Climate & Sustainability Grade 4 Climate Action SDG 13 What Can We Do

Grade 4 Science – Climate Action (SDG 13): What Can We Do?

1. The Driving Question

"If the Earth is getting warmer and weather is getting weirder, why does what I do—like turning off lights or riding my bike—even matter? Can one kid (or one school, or one town) really change something as big as the whole planet’s climate?"

By the end of this guide, you’ll know exactly how small actions add up, why some choices matter more than others, and how to spot the difference between "feel-good" fixes and real solutions.

2. The Core Idea – Built, Not Listed

Imagine your classroom is a giant terrarium—a sealed glass box with plants, soil, and a tiny bit of water. If you leave it in the sun, the air inside gets warmer. If you add a fan (like wind), the heat spreads out. If you put in too many plants, they use up all the air and the system breaks. Now, zoom out: Earth is our giant terrarium, but instead of glass, we have the atmosphere trapping heat like a blanket. Every time we burn gas in a car, cut down a forest, or even throw away a plastic bottle, we’re adding extra "blankets" or poking holes in the system. The good news? Just like in the terrarium, small changes—like using less energy or planting trees—can help rebalance things.

But here’s the catch: not all actions are equal. Turning off a light saves energy, but convincing your town to build a wind farm saves way more. Climate action isn’t just about being "green"—it’s about being strategic. Think of it like a video game: some moves give you 10 points, others give you 1,000. Your job is to figure out which is which.

Key Vocabulary:
- Carbon footprint – The total amount of greenhouse gases (like CO₂) released by a person, place, or thing.
Example: A cheeseburger’s footprint includes the cow’s burps (methane!), the truck that delivered it, and the energy used to cook it.
- Renewable energy – Power from sources that won’t run out, like sunlight or wind.
Example: Solar panels on a school roof instead of burning coal for electricity.
- Advocacy – Speaking up to influence decisions (like laws or school rules).
Example: A 4th-grade class writing letters to the mayor to add bike lanes in their town.
- Systemic change – Fixing the rules of a system (like laws or infrastructure) so good choices are easier for everyone.
Grade 4 note: This is a big idea—you’ll learn more in middle school! For now, think of it like changing the cafeteria menu so the healthy option is the easiest choice, not the hardest.

3. Assessment Translation (Grade 4 Classroom Focus)

How this appears in class:
- Exit tickets: "Name one action you took today to reduce your carbon footprint. Explain how it helps." - Short constructed response: "Your school wants to reduce waste. Should they ban plastic water bottles or start a compost bin? Give two reasons for your choice." - Show-your-work problems: "If every student in your class turns off their computer for 1 hour a day, how many kilowatt-hours of energy would you save in a week? Use the data: 1 computer uses 0.1 kWh per hour."

Proficient vs. Developing Responses:
| Proficient | Developing | |----------------|----------------| | "We should compost because food scraps in landfills make methane, a strong greenhouse gas. Also, compost helps gardens grow, so we won’t need as many trucks to deliver soil." | "Compost is good because it helps plants." (No connection to climate or reasoning.) | | "Turning off lights saves energy, which means power plants burn less coal. Coal makes CO₂, which traps heat." | "Turning off lights is good for the Earth." (No explanation of how it helps.) |

Model Proficient Response:
Prompt: "Your family is planning a road trip. Should you drive or take the train? Give two reasons for your choice." Response: "We should take the train because trains use less fuel per person than cars. Also, trains don’t get stuck in traffic, so they’re faster and release less pollution. If we drove, we’d have to stop for gas, which comes from oil, and burning oil makes CO₂."

What teachers look for:
- Evidence: Does the answer use facts (e.g., "trains use less fuel")? - Reasoning: Does it explain how the action helps (e.g., "less fuel = less CO₂")? - Specificity: Does it name real things (e.g., "coal," "methane") instead of vague words like "bad for the Earth"?

4. Mistake Taxonomy

Mistake 1: The "Any Action = Good Action" Trap
Prompt: "List three things you can do to fight climate change." Common wrong response: 1. Recycle paper 2. Use a reusable water bottle 3. Plant a tree Why it loses credit: All three are good, but the answer doesn’t rank them. Recycling one sheet of paper saves less energy than not printing it at all, and a reusable bottle only helps if you stop buying plastic ones.
Correct approach: 1. Walk or bike to school (saves gas, reduces CO₂) 2. Eat less meat (cows make methane, a strong greenhouse gas) 3. Turn off electronics when not in use (saves energy from power plants) Why this works: It prioritizes actions with the biggest impact and explains how they help.

Mistake 2: The "One Person Doesn’t Matter" Excuse
Prompt: "Why should your family switch to LED lightbulbs?" Common wrong response: "It doesn’t matter because one lightbulb won’t stop climate change." Why it loses credit: It ignores scale. If every family in a town switches, that’s thousands of lightbulbs. Plus, LED bulbs last longer, so they reduce waste too.
Correct approach: "LED bulbs use 75% less energy than regular bulbs. If our whole town switched, we’d save as much energy as taking 100 cars off the road. Also, they don’t burn out as fast, so we’d throw away fewer bulbs." Key idea: Small actions add up—especially when lots of people do them.

Mistake 3: The "Feel-Good" Fix
Prompt: "Your school wants to reduce waste. Should they ban plastic straws or start a compost bin? Explain." Common wrong response: "Ban straws because they hurt turtles!" Why it loses credit: While straws are bad for wildlife, they make up less than 1% of plastic waste. Composting food scraps (which make methane in landfills) has a bigger climate impact.
Correct approach: "Composting is better because food scraps in landfills make methane, a greenhouse gas 25 times stronger than CO₂. Straws are a problem, but they’re a tiny part of plastic waste. Compost also helps gardens grow, so we’d need fewer trucks to deliver soil." Key idea: Some actions sound green but don’t do much. Focus on impact, not just popularity.

5. Connection Layer

1. Within science → Weather vs. Climate
   Understanding climate action helps you see why weather (short-term) and climate (long-term) are different. If you know how CO₂ traps heat, you’ll get why a cold day doesn’t mean global warming is "fake."

2. Across subjects → Math: Exponential Growth
   Climate action is about scale—like how one penny doubling every day becomes $5 million in a month. Small changes (like 1% less energy use) add up fast when millions of people do them.

3. Outside school → Fast Fashion
   The clothes you wear have a carbon footprint. A cotton T-shirt takes 700 gallons of water to make, and most end up in landfills. Now you’ll notice when brands say "sustainable" but don’t explain how.

6. The Stretch Question

"If planting trees is good for the climate, why do some scientists say we shouldn’t plant too many in certain places? What’s the catch?"

Pointer toward the answer:
Trees do absorb CO₂, but not all forests are equal. Planting trees in snowy areas (like the Arctic) can make the ground darker, so it absorbs more sunlight and warms the planet. Also, some trees (like eucalyptus) use so much water they dry out the soil, hurting other plants. The best climate action isn’t just "plant trees"—it’s "plant the right trees in the right places."
