Objective and success criteria
Students will: Evolution and fossil evidence.
- 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: Inherited and environmental characteristics
Leads to: Natural selection and resistance
Materials: Microscope images or slides, Cell diagrams, Mini whiteboards, A diagram or short video clip of the idea, Printed student sheet (below).
Warm-up · 6 min
- 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.
- Is this characteristic inherited or environmental: flower colour of a plant variety? (inherited (from parents) / environmental (from life)) → inherited (from parents)Prompt: Were you born with it, or did it happen during life?
- Identical twins have the same genes. One becomes much stronger. Why? (Their genes changed into different ones. / They are not really twins. / Strength is never affected by exercise. / The environment, such as exercise, made a difference.) → The environment, such as exercise, made a difference.Prompt: What can be different if their genes are the same?
- Inheritance: which statement is true? (Children are always exact copies of one parent. / The language you speak is inherited. / Offspring of plants and animals usually vary from their parents. / If a parent loses a finger, its babies are born without that finger.) → Offspring of plants and animals usually vary from their parents.Prompt: Which things can be passed on in genes?
Hook · 6 min
- Show a microscope image of cells and ask what students think they are looking at.
- Share the objective: Evolution and fossil evidence. Read the success criteria together.
I do: model it · 12 min
- Work through the example out loud, saying why you do each step, not just what you do.
- Example: Mary Anning was famous for…
- Step 1: Mary Anning's fossil finds helped show that species can become extinct.
- Step 2: So the answer is: finding important fossils, such as ichthyosaurs
- Answer: finding important fossils, such as ichthyosaurs
- Pause after each step and ask a student to say what comes next.
We do: guided practice · 12 min
- Do these together. Students try each step on whiteboards before you reveal it.
- Use the hints as prompts rather than giving the answer.
- What do fossils tell us about living things? (Living things have changed over very long periods of time. / Dinosaurs lived at the same time as the first humans. / Living things have never changed. / Fossils are only made of plastic.) → Living things have changed over very long periods of time.Prompt: Older rock layers contain different fossils from newer ones.
- Evolution: which statement is true? (Dinosaurs and early humans lived at the same time. / Humans evolved from modern chimpanzees. / Individual animals evolve during their own lifetime. / Variation between individuals is needed for natural selection.) → Variation between individuals is needed for natural selection.Prompt: Evolution is about populations over many generations.
You do: independent practice · 17 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 · 7 min
- Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
- Mary Anning was famous for… (inventing the telescope / finding important fossils, such as ichthyosaurs / discovering electricity / landing on the Moon) → finding important fossils, such as ichthyosaursPrompt: She searched the cliffs of the Jurassic Coast in England.
- Evolution: which statement is true? (Species can become extinct. / Humans evolved from modern chimpanzees. / Dinosaurs and early humans lived at the same time. / Individual animals evolve during their own lifetime.) → Species can become extinct.Prompt: Evolution is about populations over many generations.
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: Inherited and environmental characteristics.
- Use concrete materials: microscope images or slides.
- 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: Natural selection and resistance.
- 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.
