Student lesson
- Renewable resources are replaced naturally.
- Solar and wind do not run out.
- Many are weather-dependent.
- Sustainable management is needed for forests and fish.
Words to know
able to be replaced naturally within a human lifetime
energy from sunlight
electricity from moving water
fuel from plants or waste
1. Discover: The windy hill
On a hill above the village a row of wind turbines turns slowly. “The wind is free and never runs out,” says Ms Acheampong, “but what happens on a still day?” The class discusses storage and mixing sources.
Think: What other source could fill the gap?
2. Understand: Renewables
Idea 1: Sources
Renewable sources include solar energy, wind, hydroelectric power, geothermal heat, tides and biomass. Forests and fish are renewable only if harvested sustainably.
Idea 2: Advantages
They produce little or no greenhouse gas while operating, rarely run out and can be built at many scales, from a village solar lamp to a large dam.
Idea 3: Limits
Sun and wind vary, so we need storage and a mix of sources. Dams can flood habitats and homes. Building any system uses materials and land.
3. Worked examples
Example 1 (I show you): Match
Source and use.
- Solar.
- Wind.
- Hydro.
Answer: Examples.
Example 2 (We do it together): Compare
Pros and cons.
- Cheap running.
- Weather.
- Land.
Answer: Trade-offs.
Example 3 (You try): Plan
Mix.
Show the steps and answer
- Sun.
- Wind.
- Storage.
Answer: Reliable supply.
Did you know?
In a year the Sun delivers more energy to Earth than humanity uses in several thousand years.
Why this matters
Renewables are central to cutting emissions while meeting energy needs.
4. Explore: Model turbine
Make a paper pinwheel, hold it in front of a small desk fan (guarded, on low) and compare how many turns per ten seconds at low and medium speed.
- Make a pinwheel.
- Use a guarded fan.
- Count turns.
- Compare.
Think about it: what did you notice?
What did you notice? Faster wind gave more turns.
5. Practise
Say it in a sentence
Use these starters when you talk about the lesson. Say them out loud.
- A ___ resource is replaced naturally.
- ___ energy comes from sunlight.
- ___ power uses moving water.
- ___ is fuel from plants or waste.

Courseversity badge thresholds (overall quiz score): Gold = 90–100%; Silver = 80–89.9%; Bronze = 70–79.9%. A badge is never a full record of progress.
If a learner struggles
- Find the misconception: “Renewable means no impact.” Some impact.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Evaluate renewable resources.
- 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 renewable resources. You do not need to be an expert to help.
- Spot solar panels.
- Ask “What powers it?”
- Mind spinning fans.
- 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 renewable; describe sources; compare advantages and limits; build a model.
Prerequisite knowledge. Grade 5 ideas: weather, water cycle, ecosystems and human impact.
Materials. Paper, split pin, guarded fan. 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. Test the fan.
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). Spin a pinwheel and ask, “What powers it?”
Explanation (10 min). Teach renewables.
Guided activity (10 min). Learners test.
Independent activity (10 min). Learners explain.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. What renews? What are the limits?
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. “Renewable means no impact.” Some impact.
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. Evaluate renewable resources. 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.
