Plant reproduction: seeds versus runners, bulbs, tubers and cuttings
Plants
CCSS NGSS.3-LS1-1England: KS2 Y5 Living things and their habitats
Objective and success criteria
Students will: Plant reproduction: seeds versus runners, bulbs, tubers and cuttings.
- I can answer questions on today's skill on my own, without help.
- I can explain each step and say why it works.
- I can check my answer and spot a mistake.
Before and after
Needs first: Pollination and seed dispersal
Leads to: the next skill in this area.
Materials: Real plants or seeds, Hand lenses, Mini whiteboards, A diagram or short video clip of the idea, Printed student sheet (below).
Warm-up · 5 min
- Quick retrieval from earlier learning (Pollination and seed dispersal). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- How are the seeds of this plant mainly spread: thistle? (wind / animals / water / exploding pods) → windPrompt: Are the seeds light and fluffy, hooked or tasty, able to float, or in a pod?
- Which part of the flower makes pollen? (the petal / the root / the stigma / the anther (part of the stamen)) → the anther (part of the stamen)Prompt: It is at the top of the stalks in the middle of the flower.
- Which plant's seeds are mainly spread by wind? (gorse / cherries / water lily / sycamore (maple)) → sycamore (maple)Prompt: Think about the shape of each seed or fruit.
Hook · 5 min
- Bring in a plant that has been kept in the dark next to one in the light, and ask what happened.
- Share the objective: Plant reproduction: seeds versus runners, bulbs, tubers and cuttings. Read the success criteria together.
I do: model it · 10 min
- Work through the example out loud, saying why you do each step, not just what you do.
- Example: How is this new plant produced: a daffodil bulb splitting into new bulbs?
- Step 1: A new plant grows from part of one parent and is identical to it.
- Step 2: So the answer is: from part of one parent (asexual reproduction)
- Answer: from part of one parent (asexual reproduction)
- Pause after each step and ask a student to say what comes next.
We do: guided practice · 10 min
- Do these together. Students try each step on whiteboards before you reveal it.
- Use the hints as prompts rather than giving the answer.
- How is this new plant produced: a geranium cutting in water? (from seeds (sexual reproduction) / from part of one parent (asexual reproduction)) → from part of one parent (asexual reproduction)Prompt: Did it come from a seed, or from a piece of one plant?
- Gardeners take cuttings from a rose bush with perfect flowers. Why not just plant its seeds? (Cuttings grow into plants identical to the parent; seeds may differ. / Seeds are only for trees. / Cuttings grow slower. / Rose seeds never grow.) → Cuttings grow into plants identical to the parent; seeds may differ.Prompt: Which method has only one parent?
You do: independent practice · 10 min
- Students work on the student sheet. Circulate and check the first two answers of every student early.
- Students who finish: write a question of their own for a partner, with the answer.
The 8 questions are on the student sheet below, with answers in the key.
Exit ticket · 5 min
- Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
- How is this new plant produced: a potato tuber sprouting? (from seeds (sexual reproduction) / from part of one parent (asexual reproduction)) → from part of one parent (asexual reproduction)Prompt: Did it come from a seed, or from a piece of one plant?
- What is one advantage of plants making seeds rather than copies? (Seeds are always identical. / Copies spread further. / Seeds need no pollination. / Seeds create variety, so some young may survive changes such as new diseases.) → Seeds create variety, so some young may survive changes such as new diseases.Prompt: If every plant were identical, one disease could affect them all.
Watch out for
- Everyday meanings of words getting in the way of the science meaning: define key words explicitly.
- Remembering facts without the reason: ask "why?" and "what is the evidence?"
Support and stretch
Support
- Review first: Pollination and seed dispersal.
- Use concrete materials: real plants or seeds.
- Give the first step of each question, or a partly worked example to finish.
- Pair with a confident partner for the guided practice.
Stretch
- Explain a common mistake in writing and how to fix it.
- Write a word problem that uses today's skill, then solve a partner's.
