Student lesson
Words to know
water falling from clouds
a tool that measures rainfall
balls of ice from storm clouds
a seasonal wind that brings heavy rain
1. Discover: The rain gauge
Afua sets up a rain gauge: a clear bottle with a ruler scale. After a storm she reads 18 millimetres. “That much water covers the ground to a depth of 18 mm,” she says.
Think: Why do farmers record rainfall?
2. Understand: Precipitation
Idea 1: Formation
Tiny cloud droplets or ice crystals collide and grow. When they are heavy enough, gravity pulls them down as precipitation.
Idea 2: Kinds
Rain and drizzle are liquid. Snow is ice crystals. Sleet is partly melted snow. Hail forms in strong storm clouds as layers of ice.
Idea 3: Measuring
A rain gauge collects rain in a straight-sided container with a scale in millimetres. West Africa gets most rain in the wet season, and some regions have a monsoon.
3. Worked examples
Example 1 (I show you): Name
Ice balls.
- Hail.
- Storm.
- Layers.
Answer: Hail.
Example 2 (We do it together): Measure
Rain gauge.
- Straight sides.
- mm.
- Level.
Answer: Read in millimetres.
Example 3 (You try): Explain
Why farmers care.
Show the steps and answer
- Crops.
- Season.
- Water.
Answer: Rain feeds crops.
Did you know?
The largest hailstone ever recorded in the United States was about 20 centimetres across.
Why this matters
Precipitation fills rivers, feeds crops and shapes climate.
4. Explore: Rain gauge
Make a rain gauge from a plastic bottle and ruler, place it outdoors and record daily rain for a week.
- Cut the bottle (adult).
- Invert the top.
- Add a mm scale.
- Record daily.
Think about it: what did you notice?
What did you notice? Rainfall varied a lot from day to day.

If a learner struggles
- Find the misconception: “Rain comes from the Sun.” From clouds.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Measure precipitation.
- 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 measures rainfall. You do not need to be an expert to help.
- Place a cup outside.
- Ask “How much fell?”
- Stay in during storms.
- 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: name forms of precipitation; explain formation; measure rainfall; link to climate and farming.
Prerequisite knowledge. Grade 4 ideas: rocks and soils, weather, the water cycle basics, evaporation and condensation.
Materials. Bottle, ruler, tape. 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. Cut bottles.
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). Look out the window on a wet day and ask, “How much rain?”
Explanation (10 min). Teach precipitation.
Guided activity (10 min). Learners build.
Independent activity (10 min). Learners record.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. How much? What kind?
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. “Rain comes from the Sun.” From clouds.
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. Measure precipitation. 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.
