Student lesson
- Weather affects crops.
- Farmers plant with the rains.
- Drought and floods harm crops.
- Forecasts help farmers plan.
Words to know
a plant grown for food or use
to gather ripe crops
a long time with little rain
a prediction of future weather
1. Discover: The late rains
Farmer Yaa waits for the first heavy rains before planting maize. This year they come two weeks late. A radio forecast says more rain is coming. “I will plant now,” she says. “The soil is wet enough.”
Think: How does Yaa use the forecast?
2. Understand: Farming
Idea 1: Weather and crops
Crops need the right amount of sunlight, warmth and water. The seasons tell farmers when to plant and when to harvest.
Idea 2: Using forecasts
A forecast predicts weather. Farmers also use local knowledge and records to choose when to plant, water or harvest.
Idea 3: Extremes
Drought dries crops. Floods can wash seeds away. Farmers adapt with drought-tolerant crops, irrigation, mulch and drainage.
3. Worked examples
Example 1 (I show you): Plan
Rains late.
- Wait.
- Forecast.
- Plant.
Answer: Use rains to time planting.
Example 2 (We do it together): Problem
Drought.
- Dry.
- Crops wilt.
- Adapt.
Answer: Drought harms crops.
Example 3 (You try): Adapt
Mulch.
Show the steps and answer
- Keeps water.
- Saves crops.
- Adapt.
Answer: Mulch helps in dry weather.
Did you know?
Some farmers plant millet and sorghum because they tolerate dry weather better than many other crops.
Why this matters
Understanding weather helps farmers feed communities.
4. Explore: Weather and seeds
Compare seeds grown with different amounts of water.
- Plant seeds in three pots.
- Give little, normal and a lot of water.
- Observe for two weeks.
- Record growth.
Think about it: what did you notice?
What did you notice? Too little and too much water both harmed growth.
5. Practise
Say it in a sentence

- A ___ is a plant grown for food.
- A long dry time is a ___.
- A ___ predicts weather.
- We ___ ripe crops.

If a learner struggles
- Find the misconception: “More water is always better for crops.” Too much harms.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Link weather to farming and adaptation.
- 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 weather affects farming. You do not need to be an expert to help.
- Talk with a farmer or elder.
- Ask, “When is planting?”
- Wash hands after soil.
- 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: link weather to crop growth; explain how farmers use forecasts; describe drought and flood effects; suggest ways to adapt.
Prerequisite knowledge. Grade 2 weather ideas: describing weather, the seasons, and how weather affects daily life.
Materials. Seeds, pots, soil, water, gloves. 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 pots.
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). Ask, “Why do farmers watch the sky?”
Explanation (10 min). Teach farming and weather.
Guided activity (10 min). Learners test water.
Independent activity (10 min). Learners plan.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. How does weather affect crops? How can farmers adapt?
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. “More water is always better for crops.” Too much harms.
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. Link weather to farming and adaptation. 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.
