• Quick retrieval from earlier learning (Inherited and environmental characteristics). Students answer on mini whiteboards.
• Show answers together and note who needs support in the main task.

1. Is this characteristic inherited or environmental: dyed hair? (inherited (from parents) / environmental (from life)) → environmental (from life)Prompt: Were you born with it, or did it happen during life?
2. A plant grown in a dark cupboard is tall, thin and pale. Its seeds are planted in sunlight. The new plants are… (white, because their parent was in the dark / unable to grow / normal and green, because the pale look was caused by the environment / pale, because they inherit it) → normal and green, because the pale look was caused by the environmentPrompt: Is being pale passed on in the seeds?
3. Inheritance: which statement is true? (Some characteristics depend on both genes and environment. / If a parent loses a finger, its babies are born without that finger. / Children are always exact copies of one parent. / The language you speak is inherited.) → Some characteristics depend on both genes and environment.Prompt: Which things can be passed on in genes?

• Show a microscope image of cells and ask what students think they are looking at.
• Share the objective: How the environment can change an organism's traits. Read the success criteria together.

• Work through the example out loud, saying why you do each step, not just what you do.
• Example: Flamingos are born grey. Why do adult flamingos turn pink?
• Step 1: The flamingo's diet, part of its environment, gives it its pink colour.
• Step 2: So the answer is: Pink colours in the shrimps and algae they eat build up in their feathers.
• Answer: Pink colours in the shrimps and algae they eat build up in their feathers.
• 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. Identical twins grow up in different countries. One becomes much more muscular. What best explains this? (They have different parents. / One of them grew an extra bone. / Muscles are inherited only. / Different exercise and diet changed their bodies.) → Different exercise and diet changed their bodies.Prompt: Identical twins share the same inherited information.
2. Is this trait mostly inherited, or affected by the environment: how well you can ride a bike? (mostly inherited / affected by the environment) → affected by the environmentPrompt: Was the living thing born with it, or did it come from how it lives?

• 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.

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

1. Is this trait mostly inherited, or affected by the environment: a plant leaning towards a window? (mostly inherited / affected by the environment) → affected by the environmentPrompt: Was the living thing born with it, or did it come from how it lives?
2. Traits and the environment: which statement is true? (A plant kept in the dark will pass paleness on to its seeds. / Identical twins always have exactly the same weight. / The environment cannot change any trait. / Some turtle eggs hatch as males or females depending on how warm the sand is.) → Some turtle eggs hatch as males or females depending on how warm the sand is.Prompt: Were the traits born in, or caused by how the living thing grew up?
