An Opinion Piece for You to Consider

Stewardship: Being a Good "Borrower" of the Earth

When you borrow a book from the library or a video game from a friend, you usually take extra care of it. You don't want to return it with torn pages or scratches. You know that it doesn't belong to you—you are just looking after it for a while.

I believe that our relationship with the Earth is exactly like that. We don't "own" the planet; we are just borrowing it from the people who will live here 100 years from now. That’s something I tell Skanda all the time. All the adults are borrowing their children's future. This idea is called stewardship.

In this week's issue, we see stewardship in action everywhere. We see it in the legacy of Dr. Jane Goodall, who spent 91 years being a voice for animals who couldn't speak for themselves. We see it in the scientists at GHGSat in Montreal, who are using their "space cameras" to find invisible leaks so we can keep our air clean.

Even the discovery of 20,000 dinosaur footprints in Italy is a reminder of stewardship. Those tracks survived for 210 million years! It makes me wonder: what are we leaving behind today that will still be here in a million years? Will it be something beautiful, or will it be our trash?

From Pixels to Pencils: A New Chapter for "Attempted Murder"

Speaking of leaving something behind, this week marks an important change for our comic strip. For the past few issues, The Philosopher and The Pragmatist have been brought to life by AI-generated art. But starting today, these two crows are being drawn by human hands—specifically, Skanda's hands.

Why make this change? Because I believe that the process of learning, struggling, and improving is more valuable than instant perfection. Why not others, you may ask? Well, eventually we might.

Over the last few years, Skanda and his best friend Abdullah created Billy Bob (their own) and a version/adaptation of Pikachu. It wasn't professional quality—the proportions were wobbly, the action sequences were confusing, and sometimes Pikachu looked more like a melted yellow marshmallow than a Pokémon. But it was theirs. They spent hours together, erasing and redrawing, laughing at their mistakes, and slowly getting better.

When I told Skanda about this transition, I gave him the comic script a full week in advance so he could practice. His first attempt? Obviously not Picasso or Bill Watterson or Dav Pilkey.

But I nudged him to try. I gave him suggestions. He was at it everyday until he was satisfied.

You’ll probably realize as you read the comic strip: Skanda's illustrations aren't as polished as what AI can generate in 30 seconds. The lines wobble. The feathers are inconsistent. But they show something AI can never demonstrate: human imagination. They show effort. They show a young person learning that quality work requires practice, feedback, and the willingness to start over when something isn't working.

I also told Skanda the truth: in the world he's growing up in, if he doesn't deliver quality work on time, AI will take his job. That's not a threat—it's reality. The only way to stay valuable is to do hard things, to practice what's difficult, and to improve. That's worth investing in.

So I increased his pay by $1.50 per issue—not because his art is better than AI (yet), but because his effort and growth deserve recognition.

The meta-comic you'll see this week jokes about an old philosophical puzzle called the "Ship of Theseus.". Imagine you have a wooden ship. Over time, you replace one plank because it's rotten. Then another. Then the sail. Then the mast. Eventually, you've replaced every single piece of the original ship. The question is: Is it still the same ship?

💡 DID YOU KNOW? Your body replaces almost all of its cells every seven to ten years? The skin cells you had when you were five years old are long gone. Your bones have rebuilt themselves. Even most of your brain cells have been replaced. If you're made of completely different atoms than you were when you were a baby, are you still you?

That is the philosophical discussion Ship of Theseus referenced in the comic strip.

The Waterloo Math Challenge

Finally, I'm thrilled to introduce a brand-new section this week (thanks to Praneetha for bringing this to my attention): The Waterloo Math Challenge.

Every week, the University of Waterloo's Centre for Education in Mathematics and Computing releases a "Problem of the Week" designed to make students think creatively, not just calculate answers. These aren't your typical textbook questions—they're puzzles that require logic, spatial reasoning, and sometimes a completely different way of looking at a problem.

Just like the scientists who tracked methane leaks from space or paleontologists who found footprints on vertical cliffs, mathematicians use patterns, persistence, and creative thinking to solve problems. Math isn't just about getting the right answer—it's about developing the kind of brain that can tackle challenges that don't have obvious solutions yet.

Starting this week, we'll feature two problems: one for grades 5/6 and one for grades 7/8. Try them with your family. Draw diagrams. Make mistakes. Get frustrated and then figure it out anyway.

Because that's what real learning looks like—whether you're drawing crows or solving star ring (see article 3) problems.

"The greatest danger to our future is apathy." — Dr. Jane Goodall

What do YOU think? What is one thing you "borrow" from your community (like a park or a school) that you could take better care of this week? And what's one skill you're willing to work hard at, even if AI can already do it better? Talk about this with your family over dinner tonight.

A Note to Our Readers: If you or your parents want to contribute to Your World Last Week—whether it's suggesting a story idea, sharing feedback, helping with illustrations, or proposing a new section—please do not hesitate to reach out. We can work together to make magic happen.

Remember: You don't have to read everything at once! Take your time and read one or two articles per day this week.

ARTICLE 1: Canada Opens Door to "Lost Canadians"

December 15, 2025 — Ottawa, Canada

🔍 UNDERSTANDING THE TOPIC: What Makes You a Citizen?

Think about being part of a club or team at school. Usually, if your parent is a member of the tennis club, you automatically get to join too. But imagine if the club had a rule that said: "Only the first child of members can join. Younger children are not allowed." That would feel unfair, right?

That's sort of what happened with Canadian citizenship. For years, some children born outside Canada weren't allowed to be citizens—even though their parents and grandparents were Canadian. Now, Canada has changed this rule to be fairer.

📊 INFOGRAPHIC: The Path to Canadian Citizenship

AI generated images may be incorrect, absurd, and/or hilarious

Infographic Questions:

  1. According to the infographic, how many days must a parent spend in Canada to show a "substantial connection"?
  2. Looking at the "Before" side, which generation was blocked from citizenship?
  3. About how many people may now be eligible for citizenship thanks to the new rule?

📰 ARTICLE

Tens of thousands of people around the world woke up on Monday, December 15, to discover something amazing: they were now Canadian citizens.

For years, these people were called "Lost Canadians"—a nickname for people who should have been citizens but weren't, because of confusing old rules. Now, thanks to a new law called Bill C-3, many of them finally belong.

💡 DID YOU KNOW? In government, a bill is like a "rough draft" of a law. It has to be read, discussed, and voted on by many people in Parliament before it becomes an official law. Bill C-3 was the third bill introduced in this session of the House of Commons!

What Happened?

In 2009, Canada created a rule called the first-generation limit. This rule said that if you were born outside Canada to a Canadian parent who was also born outside Canada, you couldn't automatically be Canadian.

Here's an example. Imagine a Canadian diplomat named Sarah who works at an embassy in Germany. She has a daughter named Maya, who was born in Germany. Maya is Canadian—she's the "first generation" born abroad.

But what if Maya grows up, falls in love with someone in Germany, and has her own baby there? Under the old rule, Maya's baby would not be Canadian. The baby would be "second generation" born abroad, and that's where citizenship stopped.

💡 DID YOU KNOW? Canada's first Citizenship Act was created in 1947. Before that, Canadians were technically "British subjects" rather than "Canadian citizens"!

Why Did This Rule Exist?

The government said the rule prevented people from passing down citizenship forever, even if their family had no real connection to Canada. They worried about someone whose great-great-grandparent left Canada in 1900 suddenly claiming citizenship.

But many people said the rule was too harsh. In 2023, a court in Ontario agreed. Judges ruled that the first-generation limit was unconstitutional—meaning it broke the rules in Canada's Charter of Rights and Freedoms.

💡 DID YOU KNOW? About 20,000 "Lost Canadians" have already claimed citizenship since earlier rule changes in 2009 and 2015. Bill C-3 is expected to help another 115,000 people over the next five years!

💡 DID YOU KNOW? The Charter of Rights and Freedoms is like a "rulebook" for the government. It lists the most important rights that every person in Canada has, like the right to be treated fairly and the right to live where you choose. If a law breaks these rules, judges can strike it down!

The New Rule

Bill C-3 creates a fairer system. Now, if you were born outside Canada to a Canadian parent who was also born abroad, you can still be Canadian—if your parent can prove a "substantial connection" to Canada.

What does that mean? Your parent must show they spent at least 1,095 days in Canada (that's exactly three years) before you were born. They can prove this with school records, job documents, or other paperwork.

💡 DID YOU KNOW? The number 1,095 might seem random, but it's exactly 3 × 365 days. The government chose three years because it's long enough to show a real connection to Canada, but short enough to be realistic for families who move around.

Who Does This Help?

The new law helps several groups:

  1. Military families — Canadian soldiers often serve at bases around the world. Their grandchildren born abroad are now citizens.

  1. Diplomatic families — People who work for Canada at embassies and consulates abroad.

  1. Business families — Canadians who work for international companies and live overseas.

  1. Anyone affected by old rules — Some rules from the 1947 Citizenship Act treated women and men differently. Bill C-3 fixes these unfair parts too.

💡 DID YOU KNOW? Until 1977, Canadian women who married foreign men could lose their citizenship! Meanwhile, Canadian men who married foreign women kept theirs. Bill C-3 helps restore citizenship to people affected by this unfair old rule.

What Happens Now?

People who think they might qualify can apply for a proof of citizenship document. This certificate confirms they are Canadian and lets them apply for a Canadian passport.

Immigration Minister Lena Metlege Diab said the new law makes citizenship rules "fair, clear and reflective of how Canadian families live today."

For many Lost Canadians, December 15, 2025, wasn't just another Monday. It was the day they finally came home—even if they've never set foot in Canada.

💡 DID YOU KNOW? You don't have to live in Canada to be a Canadian citizen! Canada allows dual citizenship, which means you can be a citizen of Canada and another country at the same time. About 2.8 million Canadians hold citizenship in more than one country.

📋 BACKGROUND INFORMATION: Understanding Citizenship

What is citizenship?
Citizenship is your legal membership in a country. It gives you rights (like voting and holding a passport) and responsibilities (like following laws and paying taxes).

How do you get Canadian citizenship?
There are three main ways:

  1. By birth — If you're born in Canada, you're automatically Canadian
  2. By descent — If at least one parent is Canadian when you're born, you may be Canadian too
  3. By naturalization — If you move to Canada as a permanent resident and meet certain requirements, you can apply to become a citizen

What's the difference between a citizen and a permanent resident?
A permanent resident can live and work in Canada, but cannot vote or hold a Canadian passport. A citizen can do all of those things and cannot be made to leave Canada.

Key vocabulary:

  • Unconstitutional (un-kon-stih-TOO-shun-ul): Against the rules written in a country's constitution
  • First-generation limit: A rule that stopped citizenship from passing to the second generation born outside Canada
  • Substantial connection: Proof that someone has a real relationship with Canada (like living there for three years)
  • Dual citizenship (DOO-ul SIH-tih-zen-ship):
  • Being a citizen of two countries at the same time
  • Bill: A proposed law being discussed by Parliament
  • Charter of Rights and Freedoms: Part of Canada's constitution that protects people's basic rights

  1. How many days must a Canadian parent have spent in Canada to pass citizenship to a child born abroad?

  1. What year did the first-generation limit rule begin?

  1. What court ruled that the old citizenship rule was unconstitutional?

Level 2: Between the Lines 🔍

Think about what the article means

  1. Why might a family working at a Canadian embassy abroad be affected by the old citizenship rules?

  1. The article mentions that old rules from 1947 treated men and women differently. Why would this be considered unfair today?

  1. What does the term "Lost Canadians" suggest about how these people felt about not having citizenship?

Level 3: Beyond the Line 💭

Connect to bigger ideas and your own thinking

  1. Canada allows dual citizenship, but some countries (like China and Japan) do not. What might be some advantages and disadvantages of allowing people to be citizens of more than one country?

  1. The government balanced two concerns: not giving citizenship to people with no connection to Canada, but also not being too strict with families living abroad. Do you think the "three years in Canada" rule is a good balance? Why or why not?

  1. If you were a "Lost Canadian" who just learned you're now a citizen, how do you think you might feel? What might you want to do first?

ARTICLE 2: A New Medal Honours a Legend of Conservation

December 17, 2025 — London, United Kingdom

🔍 UNDERSTANDING THE TOPIC: What Is a Legacy?

Think about a time when someone taught you something important—maybe a grandparent showed you how to cook, or a coach taught you never to give up. Even when that person isn't around anymore, what they taught you lives on. You might pass those lessons to your own friends or future children someday.

That's called a legacy—the good things someone leaves behind after they're gone. Dr. Jane Goodall spent her whole life teaching people to love and protect nature. Now, a brand-new award will make sure her lessons live on forever.

📊 INFOGRAPHIC: The Life of Dr. Jane Goodall (1934-2025)

Infographic Questions:

  1. According to the timeline, in what year was Jane Goodall born?

  3. Looking at the timeline, what major event happened in 1965?

📰 ARTICLE

Just eleven weeks after the world said goodbye to Dr. Jane Goodall, scientists and musicians gathered at a famous building in London to make sure her work will never be forgotten.

On December 17, 2025, the STARMUS Festival announced a brand-new award: the Jane Goodall Earth Medal. This medal will be given to people who work to protect our planet, defend biodiversity (the variety of life on Earth), and help humans live more peacefully with nature.

💡 DID YOU KNOW? STARMUS is a unique festival that combines science, art, and music. Its name comes from "STARS" and "MUSIC." It was started by an astronomer and a rock star (Brian May from the band Queen) to help people get excited about the mysteries of the universe!

Who Was Jane Goodall?

Dr. Jane Goodall was a British scientist who changed everything we know about chimpanzees—and about ourselves.

In 1960, when she was just 26 years old, Goodall travelled to Tanzania in East Africa. She set up camp in a forest called Gombe and began watching wild chimpanzees. Back then, most scientists studied animals from far away. Goodall did something different: she lived among them.

💡 DID YOU KNOW? Goodall was inspired to study animals after reading Tarzan of the Apes when she was 10 years old. She thought Tarzan's Jane was "a wimp" and decided she would have made a better companion for Tarzan herself!

The Discovery That Changed Science

One day, Goodall watched a chimpanzee she named David Greybeard do something amazing. He ate termites (as snacks) that he fished out of a mound—with a stick he had stripped bare of its leaves.

This was huge. Until that moment, scientists believed only humans could make and use tools. Goodall's discovery proved that animals were much smarter than we thought.

Her mentor, the famous scientist Louis Leakey, said: "We now have to redefine tool, redefine man, or include chimpanzees with humans."

💡 DID YOU KNOW? Chimpanzees share nearly 99% of their DNA with humans. They're more closely related to us than they are to gorillas!

More Than Just Science

Goodall didn't stop at research. In 1977, she founded the Jane Goodall Institute to protect chimpanzees and their habitats. Then, in 1991, she created something especially important for young people: Roots & Shoots.

Roots & Shoots is a program that helps kids take action in their own communities. Young people plant trees, clean up parks, protect local wildlife, and learn to care for the environment. Today, the program runs in 75 countries around the world—including Canada.

💡 DID YOU KNOW? Until her death, Goodall travelled about 300 days every year giving speeches and meeting with young people. She believed that "every individual can make a difference."

A Medal for Earth's Champions

The Jane Goodall Earth Medal joins another famous STARMUS award: the Stephen Hawking Medal for Science Communication, named after the legendary physicist who explained the mysteries of the universe.

The organizers said the two medals now "form a unified arc of human responsibility"—from the stars above us to the living world around us. From curiosity to compassion. From exploration to stewardship.

The first Jane Goodall Earth Medal will be awarded at STARMUS VIII, a festival of science and music happening in the Canary Islands, Spain, in October 2026.

💡 DID YOU KNOW? In 2022, LEGO released a special set honouring Jane Goodall! Set #40530 includes a Goodall minifigure and three chimpanzees in an African forest scene. In 2022, Mattel also released a Barbie doll of Goodall made from recycled plastic.

Remembering a Legend

Dr. Jane Goodall passed away on October 1, 2025, in California, while on a speaking tour. She was 91 years old. Just months before her death, U.S. President Joe Biden awarded her the Presidential Medal of Freedom—America's highest civilian honour.

People around the world paid tribute. Leonardo DiCaprio called her "a true hero for the planet." The United Nations said it had lost "an extraordinary" voice for peace.

But Goodall herself always focused on hope. In her book The Book of Hope, she wrote that even when things look dark, there are always reasons to believe in a better future—especially when young people get involved.

The Jane Goodall Earth Medal will make sure that message lives on.

💡 DID YOU KNOW? In 2021, Goodall won the Templeton Prize, one of the world's largest annual awards. Previous winners include Mother Teresa and the Dalai Lama.

📋 BACKGROUND INFORMATION: Understanding Conservation

What is conservation?
Conservation is the practice of protecting natural resources—including animals, plants, water, and land—so they exist for future generations. Conservationists work to prevent species from going extinct and to keep ecosystems healthy.

What is biodiversity?
Biodiversity means the variety of life on Earth. It includes all the different species of plants, animals, fungi, and even tiny organisms like bacteria. A forest with 500 different species has more biodiversity than one with only 50.

Why does biodiversity matter?
Every species plays a role in its ecosystem. Bees pollinate flowers. Worms break down dead plants. Wolves keep deer populations in check. When species disappear, it can cause a chain reaction that affects everything else.

Who was Stephen Hawking?
Stephen Hawking (1942-2018) was a British physicist famous for his work on black holes and the origins of the universe. Despite having a disease that left him almost completely paralyzed, he became one of the most celebrated scientists in history. The Stephen Hawking Medal, created in 2016, honours people who communicate science to the public.

Key vocabulary:

  • Primatologist (pry-mah-TOL-uh-jist): A scientist who studies primates (monkeys, apes, and related animals)
  • Ethologist (ee-THOL-uh-jist): A scientist who studies animal behaviour
  • Biodiversity (BY-oh-dih-VER-sih-tee): The variety of living things in an area or on Earth
  • Legacy (LEG-uh-see): Something handed down from someone who lived before
  • Stewardship (STEW-urd-ship): Taking responsibility to care for something (like the environment)
  • Habitat (HAB-ih-tat): The natural home of an animal or plant

ARTICLE 3: Saturn's Giant Moon May Not Have an Ocean After All

December 17, 2025 — Pasadena, California, USA

🔍 UNDERSTANDING THE TOPIC: How Scientists Change Their Minds

Imagine you're doing a science experiment at school. You mix two liquids and they turn blue. "Aha!" you think. "Mixing these always makes blue!" But then you try it again with cleaner equipment and—surprise—the mixture turns purple. You weren't wrong before. You just didn't have all the information.

That's how science works. Scientists make their best guess based on what they know. When they get better tools or look more carefully, sometimes they discover something different. That's not a mistake—that's science getting smarter!

📊 INFOGRAPHIC: What's Inside Titan?

Infographic Questions:

  1. According to the "New Idea" side, what is the middle layer of Titan made of?
  2. What is the estimated temperature of the warm water pockets?
  3. Looking at the size comparison, is Titan bigger or smaller than the planet Mercury?

📰 ARTICLE

For over 15 years, scientists believed that Saturn's giant moon Titan was hiding a secret: a massive ocean of liquid water buried deep beneath its frozen surface. Now, a fresh look at old data suggests they may have been wrong—and that's actually exciting news.

A Moon Like No Other

Titan is no ordinary moon. It's the second-largest moon in our entire solar system, measuring about 5,150 kilometres across. That's bigger than the planet Mercury! Titan is also the only moon in the solar system with a thick atmosphere—a hazy orange blanket of nitrogen that makes it look almost like a fuzzy peach from space.

Even stranger: Titan has lakes and rivers on its surface. But they're not filled with water. They're filled with liquid methane (MEH-thane)—the same gas that comes out of your stove at home. On Titan, where temperatures drop to about -179°C (-290°F), methane acts like water does on Earth.

💡 DID YOU KNOW? Titan is so cold that if you could visit, you'd find methane rain falling from orange clouds into lakes that look like they're made of liquid natural gas—because they are!

The Ocean That Wasn't

Back in 2008, NASA's Cassini spacecraft made an exciting discovery. As it flew past Titan ten times, it measured how the moon "flexed" under Saturn's gravity. The moon was squishing and stretching more than a solid ball of ice should.

Scientists concluded that Titan must have a liquid layer inside—a global ocean of water hiding beneath the ice. This was huge news because where there's liquid water, there might be life!

But a team of researchers at NASA's Jet Propulsion Laboratory (JPL) in California decided to take another look. Led by scientist Flavio Petricca, they used new computer techniques to clean up the old Cassini data. It was like putting on a better pair of glasses.

💡 DID YOU KNOW? The Cassini spacecraft orbited Saturn from 2004 to 2017. It deliberately crashed into Saturn at the end of its mission so it wouldn't accidentally contaminate any moons that might have life!

What They Found

The cleaned-up data told a different story. Instead of one big ocean, Titan probably has:

  1. A thick shell of solid ice on the outside—about 100 kilometres deep
  2. Layers of slush below that—ice that's close to melting but held solid by enormous pressure
  3. Pockets of warm liquid water scattered throughout, possibly as warm as 20°C (68°F)—that's room temperature!
  4. A rocky core at the centre

"I was introduced to the planetary science world just a few years ago, and I had always taken for granted that Titan has an ocean," Petricca said. "While working on this, it happened very often that I woke up very early in the morning because I couldn't believe what I was seeing in the data."

💡 DID YOU KNOW? Saturn has 274 known moons—more than any other planet in our solar system! Titan is by far the biggest.

Is This Bad News for Finding Life?

You might think losing an ocean is disappointing. But scientists say the opposite might be true.

"Instead of an open ocean like we have here on Earth, we're probably looking at something more like Arctic sea ice or aquifers," said Baptiste Journaux, a scientist at the University of Washington. An aquifer is an underground layer of rock that holds water—like a natural sponge.

These warm water pockets might actually be better for life than a giant ocean. The pockets could be cycling nutrients from Titan's rocky core through the slushy ice layers. Think of it like a natural recycling system that could feed tiny life forms.

💡 DID YOU KNOW? On Earth, we've found life in some of the strangest places: inside rocks, in boiling hot springs, and even in frozen Antarctic ice. Scientists call these tough organisms "extremophiles" (extreme-lovers)!

Science in Action

This story shows something important about how science works. The original Cassini scientists weren't wrong to think there was an ocean. They made the best conclusion they could with the tools they had. Now, with better techniques, scientists have a clearer picture.

"While Titan may not possess a global ocean, that doesn't preclude its potential for harbouring basic life forms," Petricca said. "In fact, I think it makes Titan more interesting."

NASA is now planning future missions to explore Titan up close. A helicopter-like drone called Dragonfly is scheduled to launch in 2028 and land on Titan in 2034. It will hop across Titan's surface, sampling the ground and searching for signs of chemistry that could support life.

💡 DID YOU KNOW? The Dragonfly mission will be the first time a flying vehicle explores another world beyond Mars. It will travel farther in one hop than any Mars rover has driven in its entire mission!

📋 BACKGROUND INFORMATION: Understanding Moons and Ocean Worlds

What is a moon?
A moon is a natural object that orbits a planet. Earth has one moon, but other planets have many more. Jupiter has 95 known moons, and Saturn has 274!

What is an "ocean world"?
In space science, an "ocean world" is any moon or planet that has liquid water, either on its surface or hidden underground. Scientists are very interested in ocean worlds because water is essential for life as we know it.

What was the Cassini mission?
Cassini was a spacecraft sent by NASA and the European Space Agency to study Saturn. It launched in 1997, arrived at Saturn in 2004, and studied the planet and its moons for 13 years. In 2017, it was deliberately crashed into Saturn to prevent any chance of contaminating moons that might have life.

Why do scientists care about Titan?
Titan is one of the most Earth-like places in our solar system (in some ways). It has an atmosphere, weather, lakes, and rivers. Even though it's extremely cold, scientists wonder if some form of life could exist there.

Key vocabulary:

  • Methane (MEH-thane): A gas on Earth, but liquid on cold Titan; the main ingredient in natural gas
  • Aquifer (AK-wih-fer): An underground layer that holds water
  • Nutrient (NOO-tree-ent): A substance that living things need to grow and survive
  • Subsurface (sub-SUR-fiss): Below the surface
  • Tidal flexing (TIE-duhl FLEHKS-ing): The way a moon gets squeezed and stretched by its planet's gravity
  • Extremophile (ex-TREE-moh-file): An organism that thrives in extreme conditions

ARTICLE 4: Photographer Finds 20,000 Dinosaur Footprints in Italian Alps

🔍 UNDERSTANDING THE TOPIC: How Do Footprints Last Millions of Years?

Think about walking on wet sand at the beach. Your footprints look perfect for a few minutes, but then waves wash them away. Now imagine if that sand dried super hard before any waves came, then got buried under more sand for millions of years. The sand turns into rock, and your footprint becomes a fossil! That's exactly how dinosaur tracks survive - they stepped in soft mud that dried, got buried, and turned to stone over millions of years.

📊 INFOGRAPHIC: "From Mud to Mountain: How Dinosaur Tracks Became Rock"

AI generated images may be incorrect, absurd, and/or hilarious

Infographic Questions:

  1. According to the infographic, how many million years ago were the footprints made?
  2. What type of rock did the sediment become over millions of years?
  3. Looking at Step 4, at what elevation (height) were the footprints found?

The Discovery

When wildlife photographer Elio Della Ferrera went hiking in September 2025, he was looking for deer and vultures, not dinosaurs. But as he scanned the rocky cliffs near Bormio, Italy, through his binoculars, something strange caught his eye. The rock face was covered in unusual dips and bumps.

After hiking half a mile through thick brush to get closer, Della Ferrera realized what he'd found: dinosaur footprints. Thousands of them. On Tuesday, December 16, 2025, scientists announced that this discovery is one of the largest collections of dinosaur tracks ever found.

The footprints are in Stelvio National Park in the Italian Alps, near where the 2026 Winter Olympics will be held. Scientists estimate there are about 20,000 footprints spread across five kilometers (three miles) of mountainside.

💡 DID YOU KNOW? The footprints were hiding in plain sight on cliffs that are 2,400 to 2,800 meters high (about as tall as 400 school buses stacked up). They were hard to spot because the walls face north and stay mostly in shadow!

"This time reality really surpasses fantasy," said Cristiano Dal Sasso, a paleontologist at Milan's Natural History Museum. He got the first call from the photographer after the discovery.

Ancient Creatures on an Ancient Beach

The tracks were made about 210 million years ago during the Triassic Period. Back then, this area wasn't a freezing mountain - it was a warm, tropical coastal region next to an ancient ocean called the Tethys Ocean.

The dinosaurs that made these prints were prosauropods - long-necked plant-eaters that walked on two (and sometimes four) legs. They could grow up to 10 meters (33 feet) long and weigh up to four tons - about as heavy as three cars. Scientists think they were similar to a dinosaur called Plateosaurus.

These gentle giants traveled in herds along the muddy tidal flats, leaving their footprints in the soft ground. When the mud dried and got buried under more sediment, the prints were preserved. Over millions of years, that mud turned into dolomite rock.

💡 DID YOU KNOW? Some of the best-preserved footprints show individual toe marks! Scientists can count the digits to figure out exactly which types of dinosaurs made them.

How Did Beach Footprints End Up on a Mountain?

Here's where the story gets really cool. The footprints didn't move - the land did. Over millions of years, powerful forces inside Earth pushed the ground upward, creating the Alps mountains. The same forces also tilted the rock layers, turning them almost vertical.

That's why these footprints are on nearly vertical cliff walls instead of lying flat on the ground. The ancient beach became a mountain, and the footprints that were once horizontal are now standing up on their side.

💡 DID YOU KNOW? This is the first time dinosaur tracks have been found in the Lombardy region of Italy, and the only ones discovered north of a major fault line called the Insubric Line in the Alps!

What Makes This Discovery Special?

Scientists are excited for several reasons. First, the sheer number of tracks - 20,000 is enormous. Second, this area has never produced dinosaur fossils before, so researchers didn't expect to find anything here.

Third, because the footprints are so well-preserved, scientists can study them in detail. "For the best-preserved footprints, we can study the number of digits to better determine the animals that produced them," Dal Sasso said.

The area has been nicknamed the "valley of the dinosaurs." Some tracks also appear to belong to archosaurs - crocodile-like reptiles that were ancestors of modern alligators and crocodiles, and another dinosaur that lived in this region millions of years later.

💡 DID YOU KNOW? The Alps weren't formed yet when these dinosaurs were alive. The mountains we see today started forming about 65 million years ago - that's 145 million years AFTER these footprints were made!

What Happens Next?

Full scientific investigation will begin in summer 2026, after the Winter Olympics are over. Researchers plan to study the tracks in detail, make 3D scans, and potentially remove some footprints to display in museums.

Stelvio National Park is also planning to build a visitor center where people can see 3D-printed copies of the best-preserved tracks and learn about the dinosaurs that once walked where Olympic skiers will soon race.

"Just a few weeks before the opening of the Milan-Cortina 2026 Winter Olympics and Paralympics, this discovery sheds an unexpected and fascinating light on the mountains of Lombardy," said Milan Mayor Giuseppe Sala.

💡 DID YOU KNOW? Elio Della Ferrera, the photographer who made the discovery, had worked with paleontologists before. When he spotted the tracks, he knew exactly who to call - his previous collaboration made this major discovery possible!

📘 BACKGROUND INFORMATION

Key Terminology:

  • Triassic Period (try-ASS-ik): A time in Earth's history about 210 million years ago when the first dinosaurs appeared.
  • Prosauropods (pro-SORE-oh-pods): Early long-necked dinosaurs that were the ancestors of the giant plant-eaters.
  • Dolomite (DOH-luh-mite): A type of hard rock that forms from ancient mud and minerals.
  • Archosaurs (ARK-oh-sores): A group of ancient reptiles that includes the ancestors of dinosaurs and crocodiles.
  • Paleontologist (PAY-lee-un-TOL-uh-jist): A scientist who studies fossils to learn about ancient life.

What is the Triassic Period? The Triassic Period lasted from 252 to 201 million years ago. It came right after the biggest mass extinction in Earth's history. Dinosaurs first appeared during the Triassic Period and weren't the largest animals yet - they shared the world with many other reptiles.

What are Prosauropods? Prosauropods were early plant-eating dinosaurs with long necks, small heads, and large bodies. They could walk on two legs or four. They lived during the Late Triassic and Early Jurassic periods. Scientists think they were ancestors of the much larger sauropods (like Brachiosaurus) that came later.

What is Dolomite? Dolomite is a type of sedimentary rock made mostly of the mineral dolomite (calcium magnesium carbonate). It forms when limestone gets altered by magnesium-rich water. The Dolomite Mountains in Italy are named after this rock, and the rock is named after the French geologist Déodat de Dolomieu.

The Tethys Ocean The Tethys Ocean was an ancient ocean that separated the northern and southern supercontinents during the Mesozoic Era (which includes the Triassic Period). As continents shifted and collided over millions of years, the Tethys Ocean closed, and its seafloor was pushed up to form mountain ranges like the Alps and Himalayas.

Canadian Connection: Our Own Dinosaur Tracks Canada has its own amazing dinosaur footprint sites! The most famous is in British Columbia's Peace River Canyon, where hundreds of tracks from different dinosaur species have been found. Alberta's Dinosaur Provincial Park also has track sites, showing that herds of dinosaurs once roamed across what is now Canada.

ARTICLE 5: The Price of Being a Kid: Canada's Youth Crisis

December 15, 2025 — Ottawa, Canada

🔍 UNDERSTANDING THE TOPIC: The "Polycrisis"

Imagine you are trying to build a Lego tower, but three different people keep trying to destroy your creation at the same time. One person is shaking the table, another is blowing a fan at your blocks, and the third is taking away your best pieces. It would be pretty hard to stay happy and finish your tower, right?

This is what some experts are calling a polycrisis (poly-CRY-sis). "Poly" means many, and "crisis" means a big problem. For young people in Canada today, the "three people" are things like high prices for food, the cost of housing, and worries about the environment. When all these problems happen at once, it can make it hard to feel positive about the future.

📊 INFOGRAPHIC: The Happiness Gap

Infographic Questions:

  1. According to the infographic, how much did grocery prices rise in November 2025?
  2. How does Canada's youth happiness rank compared to other countries this year?
  3. Looking at the "Sports Sideline," why might a family decide to stop paying for hockey or soccer?

📰 ARTICLE

For a long time, Canada was known as one of the happiest places in the world to grow up. But a major report released on Monday, December 15, 2025, shows that things are changing. Young Canadians are now part of the "unhappiest generation" in the country's history.

The Happiness Drop

The report, published by The Canadian Press, spoke to young people across the country. It found that while older Canadians are still quite happy, people between the ages of 15 and 24 are feeling "adrift."

In a global ranking of happiness, Canada's youth have seen one of the biggest declines in the world. Only four countries—including Lebanon and Afghanistan—saw a worse drop.

"We are reconfiguring our expectations," said Anthony McCanny, a researcher at the University of Toronto. This means young people are changing what they hope for because life feels more difficult.

💡 DID YOU KNOW? In 2025, Canada ranked 18th overall for happiness, but for young people, the rank was much lower. This is the first time in history that young Canadians have been less happy than their parents!

The Cost of Living

Why are young people feeling this way? A big reason is affordability. On the same day the happiness report came out, Statistics Canada released new data about prices.

It showed that the cost of food rose by 4.7% in November. Things like beef, coffee, and fresh vegetables are becoming "naughty list" items because they cost so much. When families have to spend more money on groceries and rent, there is less money left for the things that make kids happy—like travel, hobbies, and youth sports.

💡 DID YOU KNOW? The average price of a large tub of coffee hit $25 this week! That's double what it cost just a few years ago.

The "Youth Sports Crisis"

This financial pressure is creating a crisis in local sports. Many families are being "priced out" of hockey, soccer, and dance. When a season of hockey can cost thousands of dollars, it becomes a luxury that many can no longer afford.

"It's a trajectory that is not healthy," warned Toronto's police chief this week. He noted that when kids don't have affordable sports or community programs to join, they can feel disconnected from their neighbourhoods.

💡 DID YOU KNOW? Only about 35% of Canadian children are meeting their daily physical activity goals in 2025. Experts worry that high costs are keeping the other 65% on the sidelines.

Finding the "Green Hills"

Even with these big problems, young Canadians are finding ways to stay hopeful. The report calls these "green hills"—small things that bring joy. For some, it's starting a new game with friends, reading a new book, or spending time with family during the holidays.

"We have to figure it out on our own," said one young person from Vancouver. By focusing on community and helping each other, young Canadians are trying to build a happier future, even if the " Lego tower" is a bit wobbly right now.

💡 DID YOU KNOW? Despite the "polycrisis," many young Canadians are leading the way in volunteering. Canada has one of the highest rates of youth volunteering in the world!

📦 BACKGROUND INFORMATION

Key Terminology:

  • Polycrisis (poly-CRY-sis): A situation where several big problems (like the economy, the environment, and health) happen at the same time and make each other worse.
  • Affordability (uh-FORD-uh-BILL-ih-tee): Having enough money to buy the things you need and want.
  • Inflation (in-FLAY-shun): When the prices of goods and services go up over time, meaning your money buys less than it used to.
  • Consumer Price Index (CPI) (con-SOO-mer PRICE IN-dex): A tool used by the government to track how much prices are changing for average families.
  • Trajectory (truh-JEK-tuh-ree): The path or direction that something is moving in.

Historical Context:

  • 2010s: Canada consistently ranked in the top 10 happiest countries for all ages.
  • 2020-2023: The global pandemic and rising housing costs began to affect youth mental health.
  • 2025: Major reports confirm a significant "happiness gap" between young and old Canadians.

Canadian Perspective: Canada is a wealthy country, but the "cost of living" is now the #1 concern for people of all ages. For young Canadians, this means that traditional milestones—like buying a home or playing expensive sports—feel further away. However, Canadian youth are also known for being resilient and finding new ways to build community and support each other.

ARTICLE 6: Montreal Space Detectives Catch Invisible Pollution

December 16, 2025 — Montreal, Canada

🔍 UNDERSTANDING THE TOPIC: The Invisible Leak

Imagine you have a giant balloon in your living room. Suddenly, you hear a tiny hissing sound. You know air is escaping, but you can't see where the hole is because air is invisible! To find it, you might wipe soapy water over the balloon until you see bubbles.

Our planet has a similar problem with a gas called methane. It's a powerful gas that makes the Earth warmer, but it's invisible to human eyes. For a long time, we knew it was leaking from factories and mines, but we didn't know exactly where. Now, a company in Montreal has built "space cameras" that can see these invisible leaks from hundreds of kilometres above us!

📊 INFOGRAPHIC: How to Catch a Methane Leak

Infographic Questions:

  1. According to the infographic, which type of satellite gives the "Wide View" of a whole province?
  2. What size area can a GHGSat satellite focus on to find a leak?
  3. Looking at Step 3, how do scientists know where the methane is if the gas is invisible to humans?

📰 ARTICLE

While you are walking to school or playing outside, a fleet of tiny satellites is orbiting high above your head, acting like "pollution detectives." These satellites belong to a Montreal company called GHGSat, and this week, they shared a discovery that is changing how we protect our planet.

The First Global Map of Leaks

On Tuesday, December 16, scientists released the first-ever global map of methane leaks from individual buildings and factories. Using GHGSat's "space cameras," they identified 3,114 different sites around the world—including oil wells, coal mines, and landfills—that are leaking methane into the air.

Together, these sites are releasing about 9 million tons of methane every year. That is a huge amount of pollution that we couldn't see clearly until now!

💡 DID YOU KNOW? Methane is like carbon dioxide's "stronger cousin." Even though there is less of it in the air, it is 80 times more powerful than carbon dioxide at trapping heat in our atmosphere over a 20-year period!

Made in Montreal

GHGSat is based right here in Canada, in Montreal, Quebec. They are world leaders in this technology. Their satellites are quite small—about the size of a microwave oven—but they carry very special sensors.

These sensors don't take normal photos. Instead, they look for the "fingerprint" of methane. Every gas absorbs light in a different way. By looking at the sunlight reflecting off the Earth, the satellites can "see" the methane clouds that are invisible to us.

"This is a major advancement," said Dylan Jervis, a scientist at GHGSat. "We can now point to a specific facility and say, 'There is a leak right there. You need to fix it.'"

💡 DID YOU KNOW? GHGSat names its satellites after the children of its employees! Some of the satellites currently in space are named Claire, Iris, and Luca.

Why Catching Methane is a "Quick Win"

Stopping methane leaks is one of the fastest ways to help slow down climate change. Why? Because methane doesn't stay in the atmosphere as long as carbon dioxide.

If we stop a methane leak today, that gas is gone from the air in about 12 years. Carbon dioxide can stay for hundreds of years! This means that if we use these Montreal satellites to find and fix leaks right now, we can see the benefits for the Earth very quickly.

💡 DID YOU KNOW? Landfills (where our trash goes) are a big source of methane. When food scraps rot under piles of garbage, they create methane gas. GHGSat even found a massive leak at a landfill in Madrid, Spain, this year!

From Space to the Ground

Sometimes, the satellites find a leak but need a closer look. When that happens, GHGSat sends up airplanes equipped with the same sensors. These planes fly low over the factories and can find leaks as small as 5 kilograms per hour. That's like finding a tiny hole in a bicycle tire from an airplane!

By working with governments and companies, these Canadian space detectives are helping to "plug the holes" in our planet's atmosphere.

💡 DID YOU KNOW? Canada was one of the first countries to promise to reduce methane emissions by 75% by the year 2030. Our Montreal satellites are the main tools the world is using to make sure everyone keeps their promises!

  • Greenhouse Gas (GREEN-house GAS): A gas that traps heat in the Earth's atmosphere, like a blanket around the planet.
  • Plume (PLOOM): A column or "cloud" of gas or smoke spreading out from a source.
  • Constellation (KON-stuh-LAY-shun): In space terms, this also means a group of similar satellites working together as a team.
  • Facility-level (fuh-SIL-ih-tee LEH-vul): Looking at one specific building or factory, rather than a whole city or country.

Historical Context:

  • 1800s: Scientists first discovered that certain gases could trap heat (the Greenhouse Effect).
  • 2016: GHGSat launched its first satellite, "Claire," to prove that methane could be tracked from space.
  • 2021: Over 100 countries signed the "Global Methane Pledge" to reduce emissions.
  • 2025: The first global, facility-level map of methane is completed using Canadian technology.

Canadian Perspective: Canada is a world leader in "space-based Earth observation." Because Canada is so large, we have always needed satellites to see what is happening across our vast forests, oceans, and Arctic. GHGSat, based in Montreal, is a great example of how Canadian "brain power" is helping the entire world solve global problems.

❓ COMPREHENSION QUESTIONS

Level 1: On-the-Line 📖

  1. Where is the company GHGSat based?
  2. How many individual sites leaking methane did the new global map identify?
  3. How much more powerful is methane at trapping heat than carbon dioxide over 20 years?

Level 2: Between-the-Line 🔍

  1. Why does the author call GHGSat's satellites "space detectives"? What "crimes" are they solving?
  2. Explain why fixing a methane leak today helps the Earth faster than fixing a carbon dioxide leak.

Level 3: Beyond-the-Line 💭

  1. GHGSat names its satellites after the children of its employees. If you were an engineer at GHGSat and you built a new satellite, what would you name it and why? How would you feel seeing "your" satellite launch into space to save the planet?

ARTICLE 7: The "Super Flu" Surge: What You Need to Know

December 19, 2025 — Toronto, Canada

🔍 UNDERSTANDING THE TOPIC: The Virus That Changed Its Disguise

Imagine you are playing a game of "Guess Who" with a friend. You have a photo of your friend wearing a red hat and blue glasses. You know exactly what they look like! But then, your friend decides to put on a fake moustache, a wig, and a different coat. Suddenly, it's much harder to recognize them, right?

This is exactly what the flu virus does. Every year, scientists look at the flu and build a "wanted poster" (the vaccine) so your body's immune system can recognize it. But this year, a version of the flu called H3N2 changed its disguise very quickly. It added new "mutations" that make it look different to our bodies. This is why people are calling it the "Super Flu."

📊 INFOGRAPHIC: Staying Safe This Winter

Infographic Questions:

  1. According to the infographic, what is the name of the new flu variant?
  2. How many "new mutations" does this version of the flu have?
  3. Why is staying home considered a "defence move" for your friends?

📰 ARTICLE

As families across Canada get ready for the winter holidays, doctors are sending out an important message: the flu is back, and it's moving faster than usual. This year, a specific type of flu is making headlines, and some people are calling it the "Super Flu."

What is the "Super Flu"?

The real name of this virus is H3N2 subclade K. That's a long name, but you can think of it as a "cousin" of the regular flu we see every year.

The reason it's causing a stir is that it has seven new mutations. Mutations are tiny changes in the virus's DNA. These changes happened after scientists had already finished making this year's flu vaccine. Because of this, the vaccine isn't a "perfect match" for this specific strain.

💡 DID YOU KNOW? "Super Flu" isn't a medical term. Doctors just use it to describe a flu season that is more intense than normal. It doesn't mean the virus has "superpowers"—it just means it's good at hiding!

Why is it Spreading So Fast?

Because the virus changed its disguise, many people's bodies don't recognize it right away. This allows the virus to jump from person to person more easily.

In Canada, provinces like Alberta and Ontario are seeing the highest number of flu cases in over ten years. Health Canada says that children and teenagers under the age of 19 are being hit the hardest this season.

"It's like a forest fire that has plenty of wood to burn," says Dr. Donald Vinh, a doctor in Montreal. "Because many people haven't seen this specific version before, it can spread very quickly."

💡 DID YOU KNOW? The flu can travel through the air in tiny droplets when someone coughs or sneezes. These droplets can fly up to two metres—that's about the length of a twin-sized bed!

Does the Vaccine Still Work?

This is the most important question! Even though the vaccine isn't a perfect match, doctors say it is still your best defence.

Think of the vaccine like a seatbelt. A seatbelt might not stop every bump in the road, but it keeps you much safer if there is an accident. Data from Europe shows that the flu shot is still 70% to 75% effective at keeping children out of the hospital.

"The vaccine still gives your body a 'head start' in the fight," says Dr. Isaac Bogoch from Toronto. "It makes the illness much milder and helps you get better faster."

💡 DID YOU KNOW? It takes about two weeks after you get the flu shot for your body to build up its full "shield" of protection. That's why doctors suggest getting it before the holiday parties start!

How You Can Help

You have more power than you think! By following a few simple steps, you can help stop the "Super Flu" from spreading to your grandparents, your teachers, and your friends.

  1. The Elbow Sneeze: Always cough or sneeze into your elbow, not your hands.
  2. The 20-Second Scrub: Use soap and warm water. Scrub the backs of your hands and between your fingers.
  3. Listen to Your Body: If you have a fever or a scratchy throat, tell an adult. Staying home for a day or two can save your whole class from getting sick.

💡 DID YOU KNOW? Most people who get the flu feel better in about a week. The best "medicine" is usually lots of water, soup, and rest in bed while watching your favourite movie!

📦 BACKGROUND INFORMATION

Key Terminology:

  • Mutation (myoo-TAY-shun): A small change in the genetic code of a virus that can change how it looks or acts.
  • Strain (STRAYN): A specific "version" or "type" of a virus.
  • Immune System (im-YOON SIS-tum): Your body's internal army that fights off germs and viruses.
  • Mismatch (MIS-match): When the strains in the vaccine don't perfectly match the viruses actually spreading in the community.
  • Subclade (SUB-klayd): A smaller group within a larger family of viruses (like a specific branch on a family tree).

Historical Context:

  • 1918: The "Spanish Flu" was one of the most famous flu outbreaks in history.
  • 1968: The H3N2 strain first appeared and caused a global pandemic.
  • 2025: The "subclade K" mutation emerges, causing a surge in cases across the Northern Hemisphere.

Canadian Perspective: Canada has a very strong system for tracking the flu called FluWatch. Every week, doctors across the country report how many people are sick. This helps the government decide where to send more medicine and vaccines. Even though this year is tough, Canada's hospitals are working hard to make sure everyone gets the care they need.

🎨 POLITICAL CARTOON ANALYSIS: The Long Wait

Understanding Political Cartoons

Political cartoons use humor, exaggeration, and symbolism to comment on current events. They make us think critically about important issues while entertaining us. Learning to "read" political cartoons is an important media literacy skill!

This Week's Cartoon: "The Lost and Found"

Analysis Questions:

Level 1: Identifying Elements

  1. What is the label on the wooden box in the cartoon?
  2. What is the person in the box holding, and what is the guard handing to them?
  3. What years are written on the box?

Level 2: Understanding the Message 

  1. Why is the person in the box wearing old-fashioned clothes? (Hint: Look at the date 1947 on the box!)
  2. What does the "key" represent in the guard's speech? (Hint: Think about the new law, Bill C-3).
  3. Why did the cartoonist use a "Lost and Found" box to represent these people? How does it connect to their nickname?

Level 3: Critical Thinking 

  1. Political cartoons often use exaggeration. What is exaggerated in this cartoon? (Does anyone actually live in a box for 78 years?) Why did the artist choose to show it this way?
  2. The guard says "Sorry about the wait." Do you think a simple apology is enough for people who have waited decades for their rights? Why or why not?
  3. Extension: If you were to draw a cartoon about the "Super Flu" surge, what symbols would you use to show the virus and the vaccine?

Think About It: Cartoons can make a serious political problem (like citizenship laws) look funny. Does this make the problem seem less important, or does it help more people understand it?

📸 NEWS PHOTO ANALYSIS: Walking on Walls

Understanding News Photography

News photographs capture real moments in time and help us understand events happening around the world. Photographers make important choices about what to photograph, when to take the shot, and how to frame it. These choices shape how we understand the news.

This Week's Photo: "The Vertical Beach"

Artistic rendition of a photograph.

Analysis Questions:

Level 1: What Do You See?

  1. Describe the person in the photograph. What are they wearing and what are they doing?
  2. What do the "indentations" on the rock wall look like to you?
  3. What is visible in the background of the photo that tells you about the environment?

Level 2: Understanding Choices 

  1. Why do you think the photographer included the scientist in the photo instead of just taking a picture of the footprints? (Hint: Think about "scale"—how big things are!)
  2. The photo is taken during the "golden hour" when the sun is low. How does the long shadow help us see the footprints better?
  3. What story does this image tell about the work of a scientist? Is it always done in a lab?

Level 3: Critical Analysis 

  1. This photo shows footprints on a vertical wall, but we know dinosaurs couldn't walk up walls like Spider-Man. How does this photo help you visualize the "power" of the Earth to move mountains?
  2. What emotions does this photograph make you feel? (Excitement? Fear of heights? Wonder?) Why?
  3. If you were the photographer, would you have taken this photo from the ground looking up, or from a helicopter looking across? How would that change the "feeling" of the photo?
  4. Think About It: Photos can make a discovery feel "real" in a way that just reading numbers (like "20,000 footprints") cannot. Why do you think humans need to see evidence to believe it?

For Your Portfolio: If you were to take a photo of a "discovery" in your own backyard or school, what would it be? How would you frame it to make it look important?

🧮 THE WATERLOO MATH CHALLENGE

GRADE 5/6: Icy Star Rings

Michel makes coloured ice in the shape of a star ring by pouring coloured water into a special mold and freezing it. Some of his ice stars are shown.

Michel’s mold consists of an outer star and an inner star, and water is poured between the inner and outer star walls.

  1. The diagram shows the inner and outer stars from Michel’s mold. The inner star is divided into five outer triangles, shown in grey, and five inner triangles, shown in white. The outer triangles each have a base of 3 cm and a height of 1.7 cm. The inner triangles each have a base of 3 cm and a height of 2 cm. Determine the area of the inner star.

  1. If we ignore the inner star, then we can divide the outer star into five outer triangles and five inner triangles, like we did with the inner star in part (a). The base and height of each of the triangles in the outer star are twice the base and height of their corresponding triangle in the inner star. Determine the area of the outer star.

  1. The shaded region represents the area between the inner and outer star walls. Use your calculations from parts (a) and (b) to determine the area of this region.
