Student lesson
- After pollination, seeds start to form.
- The ovary grows into a fruit.
- Petals often fall off.
- Seeds are inside fruits.
Words to know
when pollen joins the female part to start a seed
the part that becomes the fruit
the part holding the seeds
a part that can grow into a new plant
1. Discover: The pawpaw
Maame cuts open a pawpaw and finds hundreds of tiny black seeds. “Where did all these come from?” she asks. Her grandmother says, “From one flower. The flower was pollinated and the fruit grew around the seeds.”
Think: What happened after the flower was pollinated?
2. Understand: Seed formation
Idea 1: Fertilisation
After pollination, the pollen joins with the female part inside the carpel. This is fertilisation. It starts a seed.
Idea 2: Fruit grows
The ovary swells and grows into a fruit. The fruit protects the seeds. Petals often dry up and fall off.
Idea 3: Many kinds
Fruits can be juicy, like mango, or dry, like groundnut pods. All hold seeds.
3. Worked examples
Example 1 (I show you): Order
Flower, pollination, seed.
- Pollination.
- Fertilisation.
- Seeds form.
Answer: Pollination leads to seeds.
Example 2 (We do it together): Fruit
What is the fruit?
- Swollen ovary.
- Holds seeds.
- Fruit.
Answer: A fruit is a grown ovary.
Example 3 (You try): Look
Cut a pawpaw.
Show the steps and answer
- Open carefully.
- Find seeds.
- Count a few.
Answer: Seeds are inside the fruit.
Did you know?
A single orchid fruit can contain millions of dust-like seeds.
Why this matters
Seeds and fruits give us food and let plants spread.
4. Explore: Fruit and seed hunt
Open fruits and find seeds.
- Choose fruits an adult has washed.
- An adult cuts them.
- Find the seeds.
- Draw and label.
Think about it: what did you notice?
What did you notice? Different fruits had different seeds.

Say it in a sentence

- The ovary becomes a ___.
- Fruits hold ___.
- Petals may fall ___.

Courseversity badge thresholds (overall quiz score): Gold = 90–100%; Silver = 80–89.9%; Bronze = 70–79.9%. A badge is never a full record of progress.
If a learner struggles
- Find the misconception: “Fruits are only sweet.” Some are dry.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Sequence flower to fruit.
- 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 seeds and fruits form. You do not need to be an expert to help.
- Cut a fruit for your child.
- Count the seeds.
- Check allergies.
- 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: describe how seeds form; link fruit to seeds; observe seeds in fruits; sequence flower to fruit.
Prerequisite knowledge. Grade 2 plant ideas: the parts of a plant, what seeds need to grow, and the plant life cycle.
Materials. Fruits, trays, plastic knife (adult use), 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. Wash fruit. Check allergies.
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 cut fruit and ask, “Where do seeds come from?”
Explanation (10 min). Teach seed formation.
Guided activity (10 min). Adult cuts fruit.
Independent activity (10 min). Learners draw.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. What happened after pollination?
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. “Fruits are only sweet.” Some are dry.
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. Sequence flower to fruit. 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.
