- Scarcity can be physical or economic.
- Water affects health, food and learning.
- Communities and governments can manage water together.
Words to know
water with little salt, found in rivers, lakes, groundwater and ice
a long period with much less rain than usual
water stored underground in soil and rock
systems for safe disposal of human waste and for hygiene
1. Discover: The long walk for water
Ms Smith tells a made-up story. A village has a river nearby, but the water is dirty and no pipe system exists. Children spend hours collecting water instead of studying. In another town there is a tank and tap system, but the taps run dry because the old pipes leak. “That is economic water scarcity: water exists but cannot be delivered safely,” she says. “In physical scarcity, there is truly not enough water. Solutions include protecting the river, repairing leaks, rainwater tanks and a community water committee.”
Think: How might clean water close to home change a village?
2. Understand: Water scarcity
Idea 1: Water on Earth
Only about 2.5% of the world’s water is freshwater, and most is frozen or underground. Groundwater is water stored in soil and rock. Rivers, lakes and rain supply what people use. About 2 billion people worldwide lack safe drinking water at home, according to United Nations agencies.
Idea 2: Kinds and causes of scarcity
Physical water scarcity means there is not enough water, often because of drought or high demand. Economic scarcity means water exists but pipes, wells, treatment and sanitation are lacking. Causes include climate change, population growth, pollution, leaks and waste.
Idea 3: Effects and solutions
Water scarcity affects health (disease), farming, school attendance, work and sometimes disputes. Solutions include protecting catchments (the land that feeds a river), repairing leaks, rainwater harvesting, safe wells, careful use, hygiene education and community committees. Freetown depends mainly on the Guma reservoir and its catchment.

Answer: Fixing a leak.
Did you know?
Handwashing with clean water and soap is one of the simplest ways to prevent the spread of disease.
Why this matters
Safe water protects health, learning and food.
4. Explore: Water audit
Use a made-up school water audit sheet: list water uses (drinking, handwashing, cleaning), record imaginary amounts, find three ways to save water, and design a poster for the school. Do not measure real water use unless the teacher supervises a safe activity.
- Read.
- List.
- Plan.
- Design.
Think about it: what did you notice?

If a learner struggles
- Find the misconception: “There is plenty of fresh water everywhere.” Only 2.5% of water is fresh.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a water 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 water scarcity using a made-up audit. Please talk about saving water at home. You do not need to be an expert to help.
- Save water.
- Fix leaks.
- Wash hands.
- 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 freshwater, drought, groundwater, sanitation, water stress; distinguish physical and economic scarcity; explain causes and effects; describe solutions.
Prerequisite knowledge. Grade 6 ideas: scarcity, production and consumption, population and urbanisation, and Grade 5 ideas about sustainable development.
Materials. Audit sheets, poster paper. 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 audit sheets.
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 long walk for water story.
Explanation (10 min). Teach water scarcity.
Guided activity (10 min). Water audit.
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 is water scarce and how can we manage it?
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. “There is plenty of fresh water everywhere.” Only 2.5% of water is fresh.
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 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.
