Student lesson

- Cutting forests destroys homes.
- We can protect habitats.
- Small actions can help.
Words to know
to keep safe from harm
harmful waste in air, water or soil
rubbish left in the wrong place
looking after nature
1. Discover: The clean-up day
On clean-up day, Class 2 picks up litter around the school pond with gloves and bags. A frog hops back into the clean water. “We made it safe again,” says Efua. “Every bit of rubbish matters.”
Think: Why is litter harmful?
2. Understand: Protecting habitats
Idea 1: Threats
Habitats are harmed by litter, pollution, cutting trees and building on wild land. Animals can lose their homes, food and clean water.
Idea 2: Why protect?
We protect habitats because living things depend on them, and so do we. Forests give clean air; rivers give water; healthy nature feeds us.
Idea 3: What we can do
We can put rubbish in bins, reuse and recycle, plant trees, save water and leave wild homes alone. This is conservation.
3. Worked examples
Example 1 (I show you): Threat?
Plastic in a pond.
- Harms animals.
- Pollutes water.
- Yes, a threat.
Answer: Plastic litter harms pond life.
Example 2 (We do it together): Action
Plant a tree.
- Gives shelter.
- Cleans air.
- A helpful action.
Answer: Planting trees helps habitats.
Example 3 (You try): Why protect?
A forest.
Show the steps and answer
- Homes for animals.
- Clean air.
- Soil protection.
Answer: Forests matter to all of us.
Did you know?
A plastic bottle can take hundreds of years to break down in nature.
Why this matters
Protecting habitats keeps nature healthy for animals, plants and people.
4. Explore: Clean-up and sort
Collect safe litter with an adult and sort it.
- Wear gloves.
- Collect dry safe items only.
- Sort into groups.
- Count and graph.
Think about it: what did you notice?
What did you notice? Most litter was plastic.

If a learner struggles
- Find the misconception: “One piece of litter does not matter.” Small pieces add up.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Name three threats and three actions.
- Guided practice: work through one example together and let the learner try the next one.
- Reassess: use the quiz again or the worksheet.
- Move on when the learner shows Silver-level evidence independently.
For parents and guardians
In this lesson your child learns how to protect habitats. You do not need to be an expert to help.
- Pick up safe litter together.
- Ask, “How does it help animals?”
- Make a poster.
- Ask “how do you know?” after each answer, and listen.
- Praise effort, not only right answers. Mistakes are how we learn.
- Ten to fifteen minutes a day is better than one long session.
Teacher package
1–5. Objectives, prerequisites, materials, preparation, duration
Lesson objectives. Learners will: name threats to habitats; say why protection matters; describe actions to protect habitats; make a simple protection plan.
Prerequisite knowledge. Grade 1 ideas: animals around us, plants around us and caring for our environment.
Materials. Gloves, bags, paper, crayons and a tally chart. Low-resource options: use chalk or charcoal on a board or wall, drawings in the sand, and objects from the classroom instead of printed materials.
Preparation. Choose a safe litter-free-of-sharps area. Prepare gloves and bags.
Suggested duration. 45–60 minutes. It can be split into two shorter sessions.
6–9. Teaching procedure, explanation notes, guided and independent activities
Introduction (5 min). Show litter in a picture and ask, “What is wrong?”
Explanation (10 min). Teach threats and actions.
Guided activity (10 min). Learners clean up safely.
Independent activity (10 min). Learners make posters.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. What harms it? What can we do?
Teacher explanation notes. Start with real objects and safe, hands-on observation. Then talk about what was seen, then draw and write. Always say “how do you know?”. Keep to the safety notes, and use local, safe materials.
10–12. Differentiation, formative assessment, common misconceptions
Support. Use real objects and pictures, short sentences and a partner. Let learners point, show or draw instead of writing. Extension. Ask learners to find a new example at home and explain how they know.
Formative assessment. Listen to learners read and explain, ask “how do you know?”, and check the independent work.
Misconceptions. “One piece of litter does not matter.” Small pieces add up.
13–15. Assessment questions, answer keys, marking scheme
Use the quiz, the 11-mark exam practice and the worksheet on this page. All answers and marking guides are in the answer sections above. Re-check every answer before use.
16–19. Remediation, enrichment, homework, teacher reflection
Remediation. Name three threats and three actions. Enrichment. Look for one new example near your home or school, draw it and explain it to someone. Homework. See above.
Teacher reflection. After teaching, record: which ideas learners understood; which misconceptions occurred; which activities worked; which learners need more practice; and what to improve next time.
