• 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.

1. Which of these does a plant need to grow well? (loud music / darkness all day / light / sweets) → lightPrompt: What does a plant get from the Sun?
2. What plants need: which statement is true? (Plants never need water. / Plants eat soil to get their food. / The more water you give a plant, the better it always grows. / Plants need air.) → Plants need air.Prompt: Think about what keeps a plant healthy.
3. What plants need: which statement is NOT true? (Plants need light to grow well. / Plants grow best in the dark. / Plants need air. / Plants need water.) → Plants grow best in the dark.Prompt: One sentence is a common mistake.

• 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.

• 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.

• Do these together. Students try each step on whiteboards before you reveal it.
• Use the hints as prompts rather than giving the answer.

1. How plants grow: which statement is true? (Plants make their own food using light energy. / Plants take in oxygen and give out only carbon dioxide all day. / Plants do not need light to make food. / Plants get most of their mass by eating soil.) → Plants make their own food using light energy.Prompt: Where does a tree's wood really come from?
2. Which gas do plants take from the air to build their bodies? (carbon dioxide / oxygen / helium / nitrogen) → carbon dioxidePrompt: It is the gas we breathe out.

• 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.

• Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.

1. How plants grow: which statement is NOT true? (The energy in plant food comes from the soil. / Plants make their own food using light energy. / Roots take in water and minerals. / Most of a plant's mass comes from carbon dioxide in the air and from water.) → The energy in plant food comes from the soil.Prompt: One sentence repeats an old idea that experiments disproved.
2. How plants grow: which statement is true? (Plants do not need light to make food. / Plants get most of their mass by eating soil. / The energy in plant food comes from the soil. / Plants release oxygen into the air.) → Plants release oxygen into the air.Prompt: Where does a tree's wood really come from?
