- Small daily habits help.
Words to know
using resources carefully so they last and nature is protected
coal, oil or gas formed from ancient plants and animals
energy from sources that do not run out, such as sun, wind and water
using less energy or materials to do the same job
1. Discover: The light switch
Ms Smith turns off a light in the classroom. “Where does the electricity for our lights come from?” she asks. “The power station,” says Abu. “In Sierra Leone, much of our power comes from water at the Bumbuna dam, which is renewable,” says Ms Smith. “Other countries burn coal or gas, which are fossil fuels. Burning them adds carbon dioxide to the air, and scientists agree that is warming the Earth.”
Think: What small habits could save electricity at school?
2. Understand: Conservation
Idea 1: Fossil fuels and renewables
Fossil fuels (coal, oil, gas) formed from ancient plants and animals over millions of years. They are limited, and burning them releases carbon dioxide, which scientists agree is warming the Earth and changing weather patterns. Renewable energy comes from the sun, wind, flowing water and plant matter, and does not run out.
Idea 2: Renewable energy in Sierra Leone
The Bumbuna hydroelectric dam on the Seli (Rokel) River uses flowing water to make electricity. Solar panels are also used in homes, schools and clinics in many parts of the country. Using renewable sources can cut pollution and make power more reliable.
Idea 3: Daily habits
Conservation means using resources carefully. Turn off lights and fans when you leave a room, use efficient bulbs and stoves, fix leaks, walk or share transport when it is safe, and reuse things. Small habits, repeated by many people, make a large difference.
3. Worked examples
Example 1 (I show you): Name
A fossil fuel.
- Think.
- Say.
- Check.
Answer: Coal.
Example 2 (We do it together): Name
A renewable source.
- Think.
- Say.
- Check.
Answer: Sun.
Example 3 (You try): Suggest
An energy-saving habit.
Show the steps and answer
- Think.
- Say.
- Check.
Answer: Switch off lights.
Did you know?
A solar panel turns sunlight directly into electricity, and many remote clinics in Africa now use solar power to run lights and keep vaccines cool.
Why this matters
Conserving resources and switching to renewable energy helps protect the climate for the future.
4. Explore: Energy savers
Make a table of ten energy-using things at school. For each, write one way to save energy. Choose two actions your class will do and create reminder signs.
- List.
- Plan.
- Choose.
- Make.
Think about it: what did you notice?
What did you notice? Small changes add up.

If a learner struggles
- Find the misconception: “Renewable energy will never run out and costs nothing.” It needs planning and equipment.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a conservation pledge.
- 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 conservation. Please practise simple energy saving at home, where this is possible. You do not need to be an expert to help.
- Switch off lights.
- Reuse things.
- Walk safely.
- 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 conservation; distinguish fossil fuels and renewables; explain climate link; describe saving habits.
Prerequisite knowledge. Grade 4 ideas: physical geography, human settlement, resources and landscape change.
Materials. Paper, 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. Prepare energy tables.
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 light switch story.
Explanation (10 min). Teach resource conservation.
Guided activity (10 min). Energy savers.
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. How can we conserve resources and use energy wisely?
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. “Renewable energy will never run out and costs nothing.” It needs planning and equipment.
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 conservation pledge. 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.
