Student lesson
- Water moves in a cycle.
- Only a small share of water is fresh and reachable.
- Wells, boreholes and dams provide water.
- Water must be treated and saved.
Words to know
the way water moves between the sea, the air and the land
water that is not salty, such as in rivers, lakes and underground
a deep narrow hole drilled to reach water underground
to make water clean and safe to drink
1. Discover: The journey of a raindrop
Ms Smith draws a raindrop. “This drop falls on a hill,” she says. “It runs into a stream, joins a river and flows to the sea. The sun warms the sea and lifts some water into the air as vapour. High in the sky it cools and forms clouds. Then it falls again as rain.” Abu asks, “Is there enough clean water for everyone?” “There is a lot of water,” says Ms Smith, “but most is salty. Fresh, clean water is precious.”
Think: Why must we take care of our water?
2. Understand: Water
Idea 1: The water cycle
The water cycle has four steps: evaporation (sun turns water into vapour), condensation (vapour cools into clouds), precipitation (rain, hail or snow falls) and collection (water gathers in rivers, lakes, the sea and underground). Water is used again and again.
Idea 2: How much is usable
About 97 percent of Earth’s water is salty. Only about 3 percent is freshwater, and most of that is locked in ice or deep underground. People get water from rivers, wells, boreholes, dams and collected rain. Sierra Leone has plenty of rain, but clean water can still be hard to reach in some places.
Idea 3: Keeping it safe and saved
Water must be purified to be safe: filtered, treated or boiled by an adult. We save water by turning off taps, fixing leaks, collecting rain and not polluting rivers. Good management shares water fairly among homes, farms and wildlife.
3. Worked examples
Example 1 (I show you): Order
Water cycle.
- Think.
- Order.
- Say.
Answer: Evaporation, condensation, rain, collection.
Example 2 (We do it together): Define
Freshwater.
- Think.
- Say.
- Check.
Answer: Not salty.
Example 3 (You try): Suggest
Show the steps and answer
- Think.
- Say.
- Check.
Answer: Fix leaks.
Did you know?
If all of the world’s water filled a bucket, the freshwater we can easily reach would be only a few drops.
Why this matters
Clean water is vital for health, farming and life.
4. Explore: Water cycle model
Draw or make a water cycle model in a sealed clear container with a teacher. Label evaporation, condensation, precipitation and collection. List five ways to save water.
- Draw.
- Label.
- Observe.
- List.
Think about it: what did you notice?
What did you notice? Water changes form and returns.

If a learner struggles
- Find the misconception: “All water is safe to drink.” Only treated water is safe.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a water-saving poster.
- 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 the water cycle and conservation. Please practise saving water at home. You do not need to be an expert to help.
- Turn off taps.
- Collect rain safely.
- Fix leaks.
- 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: describe the water cycle; explain freshwater scarcity; describe water sources and treatment; explain conservation.
Prerequisite knowledge. Grade 4 ideas: physical geography, human settlement, resources and landscape change.
Materials. Paper, pencils, clear container. 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 water cycle diagrams.
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 journey of a raindrop story.
Explanation (10 min). Teach water management.
Guided activity (10 min). Water cycle model.
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 does water move, and how can we use it 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. “All water is safe to drink.” Only treated water is safe.
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 water-saving poster. 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.
