Words to know
the clearing of forests, often permanently
planting trees to restore a forest
wood used for building and making things
the variety of living things in an area
1. Discover: The Gola forest
Mr Cole shows a map of Sierra Leone with green areas. “The Gola Rainforest National Park is one of the largest areas of rainforest left in West Africa, home to birds, monkeys and forest elephants,” he says. “Forests hold soil, clean water and store carbon. When trees are cleared for farms, charcoal or timber, habitats shrink. Communities, scientists and government work together to protect and restore forests.”
Think: What would be lost if the forest disappeared?
2. Understand: Forestry
Idea 1: Why forests matter
Forests are home to rich biodiversity. They hold soil in place, protect water sources, shade crops, influence climate, and provide food, medicine, fuel and timber. Many families rely on forest products for part of their livelihood.
Idea 2: Forests in Sierra Leone
Sierra Leone has areas of rainforest, such as Gola Rainforest National Park, and protected places like Tiwai Island and the Loma Mountains. Many species live there, some found nowhere else. Parks and reserves are managed to protect them while supporting local people.
Idea 3: Loss and recovery
Deforestation happens through clearing for farms, firewood and charcoal, logging, mining and settlement. It can cause erosion, floods, drought and loss of wildlife. Reforestation, protected areas, cleaner cooking fuels, tree nurseries, fair rules and community forest management help forests recover.
3. Worked examples
Example 1 (I show you): Define
Deforestation.
- Think.
- Say.
- Check.
Answer: Clearing forests.
Example 2 (We do it together): Define
Reforestation.
- Think.
- Say.
- Check.
Answer: Planting trees to restore.
Example 3 (You try): Name
A protected area.
Show the steps and answer
- Think.
- Say.
- Check.
Answer: Gola Rainforest National Park.
Did you know?
Tropical rainforests cover a small part of Earth but are home to a large share of its plant and animal species.
Why this matters
Protecting forests protects water, climate, wildlife and livelihoods.
4. Explore: Forest decisions
Read a short made-up case about a community near a forest. List needs for farmland, fuel and income. Suggest three ways to meet needs while protecting the forest. Give one reason for each.
- Read.
- List.
- Suggest.
- Share.
Think about it: what did you notice?
What did you notice? Solutions work best when communities help plan.

If a learner struggles
- Find the misconception: “Forests only matter to animals.” They help people too.
- 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 forests. Please plant or care for a tree if you can. You do not need to be an expert to help.
- Plant a tree.
- Save paper.
- Use wood wisely.
- 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 forest, deforestation, reforestation, timber, biodiversity; describe forests of Sierra Leone; explain causes of deforestation; explain solutions.
Prerequisite knowledge. Grade 5 ideas: natural resources, land use, resource management and conservation.
Materials. Maps, pictures. 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 pictures.
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 Gola forest story.
Explanation (10 min). Teach forests.
Guided activity (10 min). Forest decisions.
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 do forests matter and how can we protect them?
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. “Forests only matter to animals.” They help people 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. 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.
