Climate Change: Causes and Effects

Hands-on activities help second-class students grasp abstract climate science by turning it into concrete, memorable experiences. When children sort, model, and discuss real-world examples, they build lasting understanding beyond simple memorization.

• 30 min · Whole Class

Whole Class: Weather or Climate Sort

Display picture cards of daily weather like sunny days and long-term climate graphs. Students vote and sort them on the board, then discuss differences with evidence from charts. Conclude with a class anchor chart.

Explain the difference between weather and climate.

Facilitation Tip

For the Weather or Climate Sort, prepare cards with both short-term events and long-term patterns so students practice the difference through sorting and discussion.

What to look for

Ask students to draw two pictures: one showing a typical 'weather' event and another showing a 'climate' pattern. Have them label each picture and write one sentence explaining their choice.

• 45 min · Small Groups

Small Groups: Greenhouse Blanket Demo

Each group traps heat in jars: one with a plastic cover to mimic gases, one open. Use thermometers to measure warming from a lamp. Record data and compare results on group sheets.

Analyze the human activities that contribute to climate change.

Facilitation Tip

In the Greenhouse Blanket Demo, use clear plastic bags and thermometers to make the heat-trapping effect visible to all students.

What to look for

Pose the question: 'If we use less electricity at home, how does that help our planet?' Facilitate a class discussion, guiding students to connect reduced energy use to fewer greenhouse gas emissions and slower climate change.

Activity 03

• Philosophical Chairs
• 35 min · Pairs

Pairs: Mitigation Action Role-Play

Pairs draw scenarios like a family trip and act out low-carbon choices, such as walking or recycling. Perform for class and vote on best ideas. Chart class favorites.

Evaluate potential solutions and mitigation strategies for addressing climate change.

Facilitation Tip

During the Mitigation Action Role-Play, assign roles carefully so each student has a clear, achievable part to play in reducing emissions.

What to look for

Give each student a slip of paper. Ask them to write down one thing they learned about how humans cause climate change and one action they can take to help.

Activity 04

• 20 min · Individual

Individual: My Green Choices Journal

Students list three daily actions to cut emissions, like turning off lights. Draw or write them in journals, then share one with a partner for feedback.

Explain the difference between weather and climate.

Facilitation Tip

For the My Green Choices Journal, provide sentence starters and space for drawings to support students who find writing challenging.

What to look for

Ask students to draw two pictures: one showing a typical 'weather' event and another showing a 'climate' pattern. Have them label each picture and write one sentence explaining their choice.

A few notes on teaching this unit

Start with what children already know about weather before introducing climate as patterns over time. Use simple models they can see and touch, like the greenhouse demo, to avoid abstract explanations that overwhelm young learners. Research shows hands-on science boosts retention for this age group, so keep activities concrete and connected to their daily lives.

Students will confidently distinguish weather from climate, explain how human actions cause warming, and propose small changes to help the planet. Their work will show clear connections between everyday choices and global effects.

Watch Out for These Misconceptions

• During the Weather or Climate Sort, watch for students who label short-term events as climate patterns.

  Have students work in pairs to explain their choices to each other using the cards, focusing on whether each event describes today's weather or a repeating pattern over years.

• During the Greenhouse Blanket Demo, watch for students who believe greenhouse gases only exist in factories.

  Ask students to name other sources of carbon dioxide at home, like heating or car rides, and include these in a class list after the demo.

• During the Mitigation Action Role-Play, watch for students who think individual actions cannot make a difference.

  After the role-play, gather students to share how each role contributes to reducing emissions, linking actions to real-world impact.
