Which part of the plant do we eat?

Plants

CCSS NGSS.1-LS1-1England: KS1 Y1 Plants

Objective and success criteria

Students will: Which part of the plant do we eat?.

  • 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: Parts of a plant

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 (Parts of a plant). Students answer on mini whiteboards.
  • Show answers together and note who needs support in the main task.
  1. The trunk of a tree is a very thick… (root / flower / stem / leaf) → stemPrompt: It holds the tree up.
  2. Plant parts: which statement is true? (Only flowers are part of a plant. / Trees are not plants. / Leaves take in water from the soil. / A tree trunk is a stem.) → A tree trunk is a stem.Prompt: Picture a plant from its roots to its flower.
  3. Which part of a plant makes food using sunlight? (the stem / the roots / the seeds / the leaves) → the leavesPrompt: Which part is usually green and flat to catch the light?

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: Which part of the plant do we eat?. 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: Which part of the plant is this food: cauliflower?
  • Step 1: These are bunches of tiny flower buds.
  • Step 2: So the answer is: flowers (flower buds)
  • Answer: flowers (flower buds)
  • 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.
  1. Which part of the plant is this food: lentils? (leaves / flowers (flower buds) / root / seeds) → seedsPrompt: Did it grow under the ground, hold the plant up, catch sunlight, bloom, or is it something you could plant to grow a new plant?
  2. Scientists call a tomato a fruit, not a vegetable. Why? (It grows under the ground. / It is red. / It grows from a flower and has seeds inside. / It is sweet like sweets.) → It grows from a flower and has seeds inside.Prompt: Cut one open: what do you find inside?

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.
  1. Which of these foods is a seed? (a carrot / a lettuce leaf / a stick of asparagus / a pea) → a peaPrompt: Which one could you plant to grow a new plant?
  2. Three of these foods come from the same plant part: leaves. Which one does NOT? (beetroot / cabbage / kale / basil) → beetrootPrompt: Name the plant part for each food.

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: Parts of a plant.
  • 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.
