A full period's slides that reveal the comparison table one row at a time, so the class guesses before it sees.

This page is exactly what a teacher's published work will look like. Only the teacher is not real yet.

What the student does

1
Guess before the reveal
A slide shows three organelles and one question: which is missing from the animal? Then the answer comes up.
2
Compare one row at a time
A two-column table fills one row per click, so the class never sees the whole difference at once.
3
Answer at the stop slide
Every three slides there is a question slide. The class answers out loud before it moves on.
4
Write the difference in their own words
The last slide is empty but for two lines: what the plant has extra, and why it needs it.

What's inside

18 slides that cover a full period
A comparison table that fills a row at a time
4 stop slides with spoken questions

Outcomes

Names the three organelles a plant cell has and an animal cell does not.

Explains the cell wall by the plant's need to stand up without a skeleton.

Writes the difference between the two cells in two sentences of their own.

What the teacher focused on

A deck that puts the whole table on one slide ends the thinking before it starts. I reveal it row by row, and the class stays with me.

Teaching strategies

Predict, then reveal
Progressive disclosure
A spoken question every three slides

She chose a two-column table over a labelled drawing of each cell. A labelled drawing ends with the student copying names into a notebook and going quiet. The table makes them say a whole sentence: this is here, it is not there, and here is why.

Questions from inside it

1Here are three organelles: the nucleus, the cell wall, the mitochondrion. Which one is missing from an animal cell?
2Why does a plant stand upright when it has no skeleton?
3In two lines: what does a plant cell have extra, and why does it need it?

Curriculum

Grade: Grade 6
Subject: Science
Unit: The cell
Taught in: Saudi Arabia

Where this lesson sits in the curriculum

The same lesson appears in these countries' curricula. One page, five paths to it.

When to use it

The period itself

One deck covers the period end to end, and you ask the questions in between.

When a colleague covers your period

The questions and their places are in the deck, so whoever steps in knows where to stop and what to ask.

End-of-term review

Ten minutes of the same slides bring the whole difference back.

The explanation

The difference between the two cells is not a list to memorise; it follows from two ways of living. A plant stays where it is, so it builds food out of light with its chloroplasts, and it needs a stiff wall to hold it up and a big vacuole whose water keeps it taut. An animal moves to reach its food, so it does not build any, and a wall would only stop its cells from changing shape. The membrane, the cytoplasm, the nucleus and the mitochondria are in both, because every living cell needs an edge, a place to work, instructions, and energy.

Common mistakes it catches

Only a plant cell has a vacuole

An animal cell has vacuoles too — small ones, and several. The difference is size and number, not presence.

The cell wall protects the cell from microbes getting in

The wall holds the shape up. What controls entry and exit is the membrane — the wall is porous and water and salts pass straight through it.

A plant cell does not respire because it makes oxygen

It makes oxygen in the light and respires day and night. Photosynthesis and respiration run in the same cell.
