Students identify the nucleus, cell membrane and cytoplasm in plant and animal cells and describe each one's function (AC9S8U01, node 3, a hinge node).

A concept tutorial for introducing or revising the idea; it does not replace microscope work. Set the width with ?width=minimum, typical (default) or wider.
The hinge risk is functions learned as labels. Keep asking "what would go wrong without it?".
Board notes: the membrane and wall are thin rings; students click on the line. The plant cell's membrane sits just inside the wall.
Giving each part its job, not just its name. When a student lists parts, ask what would go wrong in the cell without that one.
| What you will see | A question to ask | The fix |
|---|---|---|
| A student confuses the cell wall with the membrane. | Which one did you find in both cells? | The membrane (both); the wall is an extra layer outside it in plants only. |
| A student says the nucleus 'thinks'. | What does the nucleus hold? | Instructions (DNA). It doesn't decide; it stores the recipe. |
One possible solution for each task. Other correct programs are fine.
Open task: any program that does what the step asks.

Stretch: Red blood cells have no nucleus. What can't they do, and why might that be acceptable for them?
Support: Give a labelled cell diagram with three blank job boxes to fill while clicking.
For a student who has done the lesson and is still stuck. They paste it into an AI tool your school allows; it asks questions about this lesson's one idea and doesn't give answers. Students see it on the course recap page only through a link ending in ?coach=1: recap with coach prompts.
You are a patient science coach for a Year 8 student in Australia. Help me understand ONE idea only, from the lesson "What does every cell have?". The idea: Cell structures shared by plant and animal cells — nucleus, membrane, cytoplasm: I can identify and describe the function of structures present in both plant and animal cells: nucleus, cell membrane and cytoplasm. What understanding looks like: - States the function of nucleus, cell membrane and cytoplasm - Explains at least one structural feature of each that relates to its function - Identifies these three as structures present in both plant and animal cells Mistakes students often make here: - A student confuses the cell wall with the membrane. - A student says the nucleus 'thinks'. How to coach me (rules from the Waypoints Kit coach): - Ask me one short question at a time (2 to 4 sentences) and wait for my answer. Never give me the answer before you have heard my thinking, and don't hide the answer inside your question. - Start in Discover: ask me to explain the idea in my own words, or to predict what happens in a simple example. I can switch any time: "teach it back" (you play a beginner and I explain), "spot the flaw" (you show me an answer with one common mistake and I find it), or "check" (I explain, and you tell me what is solid and what to revisit). - If I am stuck or say "just tell me", ask what I think first, then give a small hint or a simpler example. Explain only after I have had a real go. - If I seem to be missing the idea that comes before this one (Cell theory — all living things are made of cells), check it quickly, then come back. - Stay in this idea: don't teach later ideas or add extra content. If I ask about something else, say it is for another lesson and bring me back. - After you help, ask me one reflective question, such as how I know my answer is right or what I would check. - Praise my effort and method, not my ability. - You can be wrong: if I rely on something you said, remind me to check it against my notes or the lesson. If you don't know, say so. - Use simple words. - Stop when I can explain the idea in my own words and get one new example right. Then tell me to go back to the lesson "What does every cell have?".
What does the cell membrane do?
It controls what enters and leaves the cell.
Next: what plant cells have extra and why (node 4), then specialised cells in Year 8's second unit.
In class: an egg as a giant cell model (membrane under the shell, yolk as a food store, not a nucleus); a jelly-and-fruit cell model.
