• Quick retrieval from earlier learning (Variation within a group: read the data; Camouflage, warning colours and mimicry). Students answer on mini whiteboards.
• Show answers together and note who needs support in the main task.

1. Which survival trick is this: a snowy owl in snow? (camouflage (blending in) / warning colours / mimicry (copying another animal)) → camouflage (blending in)Prompt: Is the animal hiding, showing off a warning, or pretending to be something else?
2. Which survival trick is this: a harmless milk snake banded like a coral snake? (camouflage (blending in) / warning colours / mimicry (copying another animal)) → mimicry (copying another animal)Prompt: Is the animal hiding, showing off a warning, or pretending to be something else?
3. Which survival trick is this: a stick insect on a twig? (camouflage (blending in) / warning colours / mimicry (copying another animal)) → camouflage (blending in)Prompt: Is the animal hiding, showing off a warning, or pretending to be something else?

• Show a microscope image of cells and ask what students think they are looking at.
• Share the objective: Evolution: how living things change over many generations. Read the success criteria together.

• Work through the example out loud, saying why you do each step, not just what you do.
• Example: On the Galápagos Islands, Charles Darwin noticed finches with different beak shapes on different islands. What did this suggest?
• Step 1: Finches with beaks suited to the local food survived and passed on that beak shape.
• Step 2: So the answer is: Each kind had adapted to the food on its island.
• Answer: Each kind had adapted to the food on its island.
• 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. Mary Anning found fossils of sea reptiles on the English coast in the 1800s. Why were her finds important? (They were made of gold. / They proved the sea was always the same. / They showed dinosaurs lived with people. / They showed that living things very different from today's once existed and became extinct.) → They showed that living things very different from today's once existed and became extinct.Prompt: What did her ichthyosaur look like compared with animals alive today?
2. True or false? Offspring vary and are not identical to their parents. (True / False) → TruePrompt: Variation, survival and inheritance over many generations.

• 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. True or false? Evolution happens to one animal during its life. (True / False) → FalsePrompt: Variation, survival and inheritance over many generations.
2. Giraffes have long necks. Which explanation fits evolution by natural selection? (Giraffes born with longer necks reached more food, survived and had more young. / Each giraffe stretched its neck and passed the stretch to its babies. / Necks grow when giraffes sleep standing up. / Giraffes decided to grow longer necks.) → Giraffes born with longer necks reached more food, survived and had more young.Prompt: Can a change from stretching be inherited?
