Student lesson
- Seeds are dispersed by wind, water, animals and bursting pods.
- Seed features match the method.
- Dispersal gives seeds space and light.
- It reduces crowding.
Words to know
spreading seeds away from the parent
a flat part that helps a seed fly
small curved parts that stick to fur
a sudden bursting open of a pod
1. Discover: The sticky seeds
After a walk, Kofi finds small burrs stuck to his socks. “What are these?” he asks. “Seeds with hooks,” says his aunt. “They hitched a ride on you.”
Think: Why do seeds need to travel?
2. Understand: Dispersal
Idea 1: Why disperse?
Seeds that fall under the parent plant crowd each other and share the same light and water. Dispersal spreads seeds to new places.
Idea 2: Methods
Wind carries light seeds with wings or fluff. Water carries floating seeds like coconut. Animals carry seeds with hooks or eat fruits and drop seeds. Some pods burst, an explosion that flings seeds.
Idea 3: Matching
Each seed has features for its method: fluff for wind, a husk for floating, hooks for fur, tasty fruit for animals.
3. Worked examples
Example 1 (I show you): Method
Dandelion seed fluff.
- Light.
- Fluffy.
- Wind.
Answer: Dandelion seeds are wind-dispersed.
Example 2 (We do it together): Method
Coconut.
- Floats.
- Husk.
- Water.
Answer: Coconut is dispersed by water.
Example 3 (You try): Method
Burr with hooks.
Show the steps and answer
- Sticks to fur.
- Animals.
- Hooks.
Answer: Burrs use animals.
Did you know?
Some pods burst with enough force to throw seeds several metres.
Why this matters
Dispersal helps plants find new homes.
4. Explore: Seed drop
Compare how winged seeds and plain seeds fall.
- Drop a winged seed.
- Drop a plain bean from the same height.
- Compare time and path.
- Explain.
Think about it: what did you notice?
What did you notice? The winged seed spun and fell slowly.
5. Practise

If a learner struggles
- Find the misconception: “Seeds only fall straight down.” They travel.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Match seeds to dispersal methods.
- 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 travel. You do not need to be an expert to help.
- Look for seeds on a walk.
- Ask, “How does it travel?”
- Keep seeds out of mouths.
- 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: define seed dispersal; name dispersal methods; link seed features to methods; explain why dispersal helps.
Prerequisite knowledge. Grade 2 plant ideas: the parts of a plant, what seeds need to grow, and the plant life cycle.
Materials. Seeds, burrs, beans, 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. Collect seeds in advance.
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 winged seed and ask, “How might it travel?”
Explanation (10 min). Teach dispersal.
Guided activity (10 min). Learners test seeds.
Independent activity (10 min). Learners sort.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. How do the seeds travel? What features help?
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. “Seeds only fall straight down.” They travel.
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. Match seeds to dispersal methods. 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.
