- Protected areas help conserve forests.
Words to know
the clearing of forests so that land can be used for other purposes
replanting trees where forest has been cut
growing trees together with crops or livestock
the destruction of the natural home of plants and animals
1. Discover: The disappearing canopy
Mr Cole shows two made-up photographs of the same hillside, thirty years apart. In the first it is covered with tall trees; in the second there are patches of farms and bare soil. “People needed land for crops and wood for fuel and building,” he says. “But without trees, rain washes the soil away, rivers silt up, animals lose their homes and the climate changes. Communities now plant trees, protect forests such as the Gola Rainforest National Park, and grow trees with crops.”
Think: How could a village meet its need for fuel and still protect its forest?
2. Understand: Deforestation
Idea 1: Causes
Deforestation is the clearing of forests for other uses. Causes include clearing land for farming, logging for timber, cutting wood for fuel and charcoal, building roads and towns, and mining. Many people clear forests to meet real needs, so solutions must consider livelihoods.
Idea 2: Effects
Effects include soil erosion and landslides, silting of rivers, habitat loss for plants and animals, changes in rainfall, loss of timber and fruits, and more carbon dioxide in the air. Communities that depend on the forest for food, medicine and income can be affected.
Idea 3: Solutions
Solutions include laws and protected areas such as Gola Rainforest National Park, reforestation (replanting where forest was cut), afforestation (planting where there was none), agroforestry, community forestry, cleaner cooking energy and fair incomes from sustainable products such as cocoa grown under shade trees.
3. Worked examples
Example 1 (I show you): Define
Deforestation.
- Think.
- Say.
- Check.
Answer: Clearing forests.
Example 2 (We do it together): Define
Agroforestry.
- Think.
- Say.
- Check.
Answer: Trees grown with crops.
Example 3 (You try): Name

- Think.
- Say.
- Check.
Answer: Clearing for farms.
Did you know?
Forests cover about one third of the world’s land and are home to most of the world’s land-living plants and animals.
Why this matters
Forests protect soil, water, air and life, so we must care for them.
4. Explore: Cause, effect, solution chain
Using three made-up forest cards, build a chain from cause to effect to solution. Choose one solution, explain who would carry it out and how it also supports livelihoods. Present.
- Read.
- Build.
- Choose.
- Present.
Think about it: what did you notice?
What did you notice? Good solutions meet people’s needs too.

If a learner struggles
- Find the misconception: “Deforestation has only one cause.” There are many.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a forest chart.
- 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 studies causes, effects and solutions for forest loss. Please talk about caring for trees. You do not need to be an expert to help.
- Care for trees.
- Discuss needs.
- Avoid blame.
- 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: define deforestation, reforestation, afforestation, habitat loss; explain causes; explain effects; describe solutions.
Prerequisite knowledge. Grade 6 ideas: scarcity, production and consumption, population and urbanisation, and Grade 5 ideas about sustainable development.
Materials. Forest cards. 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. Prepare forest cards.
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). Tell the disappearing canopy story.
Explanation (10 min). Teach deforestation.
Guided activity (10 min). Cause effect solution chain.
Independent activity (10 min). Discuss.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. Why are forests disappearing and what can be done?
Teacher explanation notes. Start with a picture, story, map or local example. Then talk about what was seen, then draw and write. Always ask “how do you know?” and invite more than one view. Treat every family, culture and community with respect, and never ask learners to share private information.
10–12. Differentiation, formative assessment, common misconceptions
Support. Use pictures, maps, real objects and short sentences, and let learners work with a partner. Let learners point, show, act or draw instead of writing. Extension. Ask learners to find a new example from their own community and explain how they know.
Formative assessment. Listen to learners read and explain, ask “how do you know?”, and check the independent work.
Misconceptions. “Deforestation has only one cause.” There are many.
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. Make a forest chart. Enrichment. Find one new example near your home or school, draw or write about 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.
