Plant structures for growth, survival and reproduction
Plants
CCSS NGSS.4-LS1-1England: KS2 Y3 Plants
Objective and success criteria
Students will: Plant structures for growth, survival and reproduction.
- 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: How plants protect themselves
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 · 4 min
- Quick retrieval from earlier learning (How plants protect themselves). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- How is this plant part protected: a rose stem? (sticky sap (resin) / sharp thorns / thick, tough bark / tiny stinging hairs) → sharp thornsPrompt: What would hurt or annoy an animal trying to eat it?
- Some plants taste very bitter. How does this help them? (It helps them make food. / It makes their flowers bigger. / Animals learn not to eat them. / It makes them taller.) → Animals learn not to eat them.Prompt: Would you take a second bite of something horrible?
- True or false? Thorns help a plant take in water. (True / False) → FalsePrompt: Plants cannot move. How else could they stay safe?
Hook · 3 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 structures for growth, survival and reproduction. Read the success criteria together.
I do: model it · 7 min
- Work through the example out loud, saying why you do each step, not just what you do.
- Example: What does this structure do for the plant: thorns?
- Step 1: So the answer is: stop animals eating the plant
- Answer: stop animals eating the plant
- Pause after each step and ask a student to say what comes next.
We do: guided practice · 6 min
- Do these together. Students try each step on whiteboards before you reveal it.
- Use the hints as prompts rather than giving the answer.
- What does this structure do for the plant: tendrils? (curl around supports so the plant can climb / protects seeds and helps spread them / protects the trunk from damage and disease / anchor the plant and take in water and minerals) → curl around supports so the plant can climbPrompt: Is it for growing, staying safe, or making new plants?
- What is this structure mainly for: juicy fruit? (growth / protection / reproduction) → reproductionPrompt: Does it help the plant grow, stay safe, or make seeds?
You do: independent practice · 7 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 6 questions are on the student sheet below, with answers in the key.
Exit ticket · 3 min
- Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
- What does this structure do for the plant: fruit? (stop animals eating the plant / stops the leaves losing too much water / anchor the plant and take in water and minerals / protects seeds and helps spread them) → protects seeds and helps spread themPrompt: Is it for growing, staying safe, or making new plants?
- Why do trees in rainforests often have huge leaves with pointed tips? (Big leaves catch light in the shade; pointed tips let rain drip off. / To keep warm in winter. / To stop pollination. / To store snow.) → Big leaves catch light in the shade; pointed tips let rain drip off.Prompt: It is dark under the canopy and it rains a lot.
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: How plants protect themselves.
- 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.
