Student lesson
- People change habitats by farming, building and cutting trees.
- Some changes harm; some help.
- Reserves and gardens can protect wildlife.
- We can make better choices.
Words to know
what happens because of something
cutting down many trees
a protected area for wildlife
a garden that provides homes for wildlife
1. Discover: The new road
A new road is built through bushland near Moses’s village. Some birds disappear, and a pond dries. But the village also plants a tree belt and makes a small wildlife garden. “We harmed some things and helped others,” says the chief.
Think: Which change helped animals?
2. Understand: People and habitats
Idea 1: Harmful effects
Building roads and towns, deforestation, over-farming and pollution can destroy or split up habitats. Animals lose homes, food and water.
Idea 2: Helpful effects
People can make reserves, plant trees, build ponds and create garden habitats with flowers, logs and water for wildlife.
Idea 3: Better choices
We can plan carefully, use less, reuse and recycle, and protect nature when we build. Every choice has an effect on living things.
3. Worked examples
Example 1 (I show you): Helpful or harmful?
Cutting a forest.
- Homes lost.
- Soil washed away.
- Harmful.
Answer: Deforestation harms habitats.
Example 2 (We do it together): Helpful
A wildlife garden.
- Flowers.
- A log pile.
- Water.
Answer: A wildlife garden helps animals.
Example 3 (You try): Better choice
Build a road.
Show the steps and answer
- Plan to protect trees.
- Keep ponds.
- Plant new trees.
Answer: Plan carefully to reduce harm.
Did you know?
Wildlife bridges over roads let animals cross safely in some countries.
Why this matters
Our choices shape the habitats that animals and people share.
4. Explore: Helpful or harmful sort
Sort picture cards into helpful and harmful.
- Lay out cards.
- Sort into two groups.
- Explain each.
- Suggest a better choice for one harmful card.
Think about it: what did you notice?
What did you notice? Some actions can be improved.

- Deforestation means cutting ___ trees.
- A ___ protects wildlife.
- A wildlife ___ gives animals homes.

If a learner struggles
- Find the misconception: “People only harm habitats.” People can help too.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Sort effects as helpful or harmful and suggest a better choice.
- 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 people change habitats and how to choose well. You do not need to be an expert to help.
- Talk about changes in your area.
- Ask, “Who does it help or harm?”
- Plan a wildlife garden.
- 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: say how people change habitats; sort effects into helpful and harmful; explain how a change affects animals; suggest better choices.
Prerequisite knowledge. Grade 1 ideas: animals around us, plants around us and caring for our environment.
Materials. Picture cards, paper and pencils. 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. Gather before-and-after pictures. Prepare sorting mats.
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 before-and-after pictures and ask, “What changed?”
Explanation (10 min). Teach effects.
Guided activity (10 min). Learners sort cards.
Independent activity (10 min). Learners suggest better choices.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. Helpful or harmful? What is a better choice?
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. “People only harm habitats.” People can help too.
13–15. Assessment questions, answer keys, marking scheme
Use the quiz, the 10-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. Sort effects as helpful or harmful and suggest a better choice. 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.
