Objective and success criteria
Students will: Which cell parts are in plant cells, animal cells or both?.
- 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: Plant and animal cells
Leads to: the next skill in this area.
Materials: Microscope images or slides, Cell diagrams, Mini whiteboards, A diagram or short video clip of the idea, Printed student sheet (below).
Warm-up · 5 min
- Quick retrieval from earlier learning (Plant and animal cells). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- Which part of a cell is a thin layer around the cytoplasm? (chloroplasts / nucleus / cell wall / cell membrane) → cell membranePrompt: Think about which parts are only in plant cells.
- Cells: which statement is NOT true? (Bacterial cells have no nucleus. / Both plant and animal cells have a nucleus, cytoplasm and a cell membrane. / Most plant cells have a large permanent vacuole. / Only animal cells have mitochondria.) → Only animal cells have mitochondria.Prompt: Do plant cells respire?
- Which part of a cell is made of cellulose? (mitochondria / nucleus / cell membrane / cell wall) → cell wallPrompt: Think about which parts are only in plant cells.
Hook · 5 min
- Show a microscope image of cells and ask what students think they are looking at.
- Share the objective: Which cell parts are in plant cells, animal cells or both?. Read the success criteria together.
I do: model it · 10 min
- Work through the example out loud, saying why you do each step, not just what you do.
- Example: Where is this found: cell membrane?
- Step 1: Nucleus, cell membrane, cytoplasm, mitochondria and ribosomes are in both.
- Step 2: So the answer is: both plant and animal cells
- Answer: both plant and animal cells
- Pause after each step and ask a student to say what comes next.
We do: guided practice · 10 min
- Do these together. Students try each step on whiteboards before you reveal it.
- Use the hints as prompts rather than giving the answer.
- Where is this found: cytoplasm? (plant cells only / both plant and animal cells) → both plant and animal cellsPrompt: Plant cells have everything animal cells have, plus some extras.
- Onion skin cells are from a plant, but they have no chloroplasts. Why? (The onion bulb grows underground, away from light / Onion cells are animal cells / Chloroplasts are only found in flowers / Onions are not living things) → The onion bulb grows underground, away from lightPrompt: Do all plant cells photosynthesise?
You do: independent practice · 10 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 8 questions are on the student sheet below, with answers in the key.
Exit ticket · 5 min
- Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
- Under a microscope, cells have regular box shapes, green discs and a large central space. They come from… (a leaf / human blood / a frog's skin / a cheek swab) → a leafPrompt: Which cell type has chloroplasts and a vacuole?
- Plant and animal cells: which statement is NOT true? (Plant cells do not need mitochondria because they photosynthesise. / Not every plant cell has chloroplasts. / Both plant and animal cells have mitochondria. / Animal cells have a cell membrane but no cell wall.) → Plant cells do not need mitochondria because they photosynthesise.Prompt: Do plants respire as well as photosynthesise?
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: Plant and animal cells.
- 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
- 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.
