Life cycle of a flowering plant
Plants
CCSS NGSS.3-LS1-1England: KS2 Y3 Plants
Objective and success criteria
Students will: Life cycle of a flowering plant.
- 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: Seeds, bulbs and germination
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 (Seeds, bulbs and germination). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- Is this a seed or a bulb: tulip? (seed / bulb) → bulbPrompt: Seeds are usually small and hard. Bulbs are rounder, with papery layers.
- What grows first out of a germinating bean? (a root / a flower / a new bean / a fruit) → a rootPrompt: The plant needs to hold on and find water first.
- Which of these is a bulb? (sunflower seed / bean / tulip / acorn) → tulipPrompt: Seeds come from inside fruits and pods. Bulbs are round and have papery layers.
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: Life cycle of a flowering plant. 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: In the life cycle of a bean plant, what comes straight after "plant with flowers"?
- Step 1: bean seed → root and shoot appear → seedling → plant with flowers → pods with new beans
- Step 2: So the answer is: pods with new beans
- Answer: pods with new beans
- 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.
- In the life cycle of a flowering plant, what comes straight after "germination"? (seed / adult plant / flowering / seedling) → seedlingPrompt: The cycle starts and ends with seeds.
- After pollination, which part of the flower becomes the fruit? (the petals / the roots / the stem / the ovary) → the ovaryPrompt: It is the part that holds the ovules, which become seeds.
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.
- In the life cycle of a bean plant, what comes straight after "root and shoot appear"? (bean seed / seedling / plant with flowers / pods with new beans) → seedlingPrompt: Picture the plant growing bigger, then making seeds.
- What is the young plant that grows from a seed called? (a seedling / a bulb / a fruit / a petal) → a seedlingPrompt: Its name has the word "seed" in it in English.
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: Seeds, bulbs and germination.
- 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.
