Objective and success criteria
Students will: Plants make food from air and water.
- 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: What plants need to grow
Leads to: Photosynthesis; The energy in food started as sunlight
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 (What plants need to grow). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- A plant is not watered for a long time. What happens? (Its leaves turn blue. / It wilts (droops) and may die. / It makes more flowers. / It grows taller.) → It wilts (droops) and may die.Prompt: Plants need water to stay firm.
- What plants need: which statement is true? (The more water you give a plant, the better it always grows. / Plants never need water. / Plants need light to grow well. / Plants grow best in the dark.) → Plants need light to grow well.Prompt: Think about what keeps a plant healthy.
- What plants need: which statement is NOT true? (Plants need water. / Plants need light to grow well. / The more water you give a plant, the better it always grows. / Plants need air.) → The more water you give a plant, the better it always grows.Prompt: One sentence is a common mistake.
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: Plants make food from air and water. 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: How plants grow: which statement is true?
- Step 1: “The energy in plant food comes from the soil.” is not true: The energy comes from sunlight.
- Step 2: So the answer is: Most of a plant's mass comes from carbon dioxide in the air and from water.
- Answer: Most of a plant's mass comes from carbon dioxide in the air and from water.
- 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.
- How plants grow: which statement is true? (The energy in plant food comes from the soil. / Plants release oxygen into the air. / Plants do not need light to make food. / Plants take in oxygen and give out only carbon dioxide all day.) → Plants release oxygen into the air.Prompt: Where does a tree's wood really come from?
- What do plants take in through their roots? (carbon dioxide / sunlight / water and minerals / sugar) → water and mineralsPrompt: Roots are in the soil.
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 do plants take in through their roots? (sugar / water and minerals / sunlight / carbon dioxide) → water and mineralsPrompt: Roots are in the soil.
- How plants grow: which statement is NOT true? (The energy in plant food comes from the soil. / Most of a plant's mass comes from carbon dioxide in the air and from water. / Plants release oxygen into the air. / Plants make their own food using light energy.) → The energy in plant food comes from the soil.Prompt: One sentence repeats an old idea that experiments disproved.
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: What plants need to grow.
- 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
- Move on to: Photosynthesis; The energy in food started as sunlight.
- 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.
