Student lesson
- Farmers use science ideas.
- Soil and water help crops grow.
- Tools make farm work easier.
- Farm animals need food, water and care.
Words to know
land used to grow crops or raise animals
to gather ripe crops
the top layer of ground where plants grow
something added to soil to help plants grow
1. Discover: The maize field
Kwame’s uncle waters his maize field in the dry season, adds compost to the soil and uses a hoe to remove weeds. “Maize needs good soil, water and light,” he says. “That is science.”
Think: What does the maize need?
2. Understand: Farming and science
Idea 1: Crops
Crops need good soil, water and sunlight. Farmers add compost or fertiliser to give plants food. They choose seeds that suit the weather.
Idea 2: Tools
Simple machines help: a hoe is a lever, a wheelbarrow carries loads and a plough turns the soil. Tools make work easier.
Idea 3: Animals and harvest
Farm animals need feed, clean water and shelter. Farmers watch for sickness. At harvest crops are gathered and stored in dry places.
3. Worked examples
Example 1 (I show you): What helps?
Compost.
- Adds food.
- Plants grow.
- Good soil.
Answer: Compost feeds the soil.
Example 2 (We do it together): Tool
A hoe.
- Removes weeds.
- Lever.
- Easier.
Answer: A hoe is a simple machine.
Example 3 (You try): Harvest
Maize.
Show the steps and answer
- Ripe.
- Gathered.
- Stored dry.
Answer: Store harvest in a dry place.
Did you know?
A single maize plant can produce hundreds of kernels.
Why this matters
Science helps farmers grow more food using less water and land.
4. Explore: Soil test
Compare soil types for plant growth.
- Fill cups with sandy and loamy soil.
- Plant a bean in each.
- Water the same.
- Record growth.
Think about it: what did you notice?
What did you notice? Soil type affected growth.

If a learner struggles
- Find the misconception: “Any soil is fine.” Soil quality matters.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Explain three ways science helps farmers.
- 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 science helps farmers. You do not need to be an expert to help.
- Visit a farm or garden.
- Ask, “What does it need?”
- Plan a garden.
- 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 science ideas to farming; name farm tools and what they do; explain why soil and water matter; describe how farmers care for animals.
Prerequisite knowledge. Grade 1 ideas: caring for our environment, keeping clean and healthy and noticing how people use materials.
Materials. Cups, soil, seeds, rulers and 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 soil samples. Prepare record 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). Show a farm picture and ask, “Where is the science?”
Explanation (10 min). Teach farming science.
Guided activity (10 min). Learners compare soils.
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. What does it need? What tool helps?
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. “Any soil is fine.” Soil quality matters.
13–15. Assessment questions, answer keys, marking scheme
Use the quiz, the 9-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. Explain three ways science helps farmers. 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.
