to use more than needed
a small hole that lets water escape
to use water again
1. Discover: The dripping tap
Selina notices a dripping tap behind the school kitchen. She puts a bowl under it and, after a day, it has collected a whole bucket. “That is a lot of wasted water,” says her teacher. The tap is fixed and the class makes posters.
Think: How could we have saved it?
2. Understand: Saving water
Idea 1: Why save?
Fresh water is limited. In dry seasons wells and rivers can run low. When we conserve water there is more for everyone.
Idea 2: Ways to save
Turn off taps, fix leaks, use a cup to brush teeth, take short washes and water plants in the evening. Do not waste water.
Idea 3: Reuse
Used water from washing vegetables can water plants. Rainwater can be collected in clean containers. This is a way to recycle water.
3. Worked examples
Example 1 (I show you): Save?
A running tap while brushing teeth.
- Wastes water.
- Turn it off.
- Use a cup.
Answer: Turn off the tap to save water.
Example 2 (We do it together): Leak
A dripping tap.
- Drips add up.
- Fix it.
- Save a bucket a day.
Answer: Fix leaks to save water.
Example 3 (You try): Reuse
Veg washing water.
Show the steps and answer
- Water plants.
- Not wasted.
- Reuse.
Answer: Reuse water for plants.
Did you know?
A tap dripping once per second can waste more than 10,000 litres in a year.
Why this matters
Saving water protects the environment and helps communities in dry seasons.
4. Explore: Measure water use
Measure the water used for washing hands with and without turning off the tap.
- Wash hands with a basin for 10 seconds.
- Count cups used.
- Compare running water vs basin.
- Record in a table.
Think about it: what did you notice?
What did you notice? Running water uses much more.
5. Practise
Say it in a sentence
Use these starters when you talk about the lesson. Say them out loud.
- We ___ water to save it.
- A ___ wastes water.
- We can ___ water for plants.
- Fix a ___.

If a learner struggles
- Find the misconception: “Water will never run out.” It can be short.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: List five ways to save water and explain why.
- 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 learns how to save water at home. You do not need to be an expert to help.
- Find leaks together.
- Ask, “How can we save?”
- Make a water plan.
- 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: say why saving water matters; list ways to save water; measure water use; make a water-saving plan.
Prerequisite knowledge. Grade 1 ideas: weather and the sky, water around us and keeping our environment clean.
Materials. Cups, bowls, paper, crayons and tally sheets. 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 basins. Prepare record 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). Show a dripping tap picture and ask, “What is wrong?”
Explanation (10 min). Teach conservation.
Guided activity (10 min). Learners measure water.
Independent activity (10 min). Learners make posters.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. How can we save water? How much?
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. “Water will never run out.” It can be short.
13–15. Assessment questions, answer keys, marking scheme
Use the quiz, the 11-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. List five ways to save water and explain why. 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.
