Watch It Move: Osmosis
A “Watch it move” animation for Biology Made Fun, Unit 5 — the code printed on page 57, Unit 5's Color & Learn three-cups page.
Animation — OsmosisThe concept animation for this page will be embedded here.
Key ideas from the lesson
- Osmosis is the movement of water across the membrane toward the side with more dissolved material.
- Put a cell in water with less dissolved material than the cell's inside and water rushes in — the cell swells.
- Reverse the setup — more dissolved material outside — and water leaves, and the cell shrivels. The membrane controls the traffic either way.
Why this helps
This is the “Watch it move” companion to Unit 5's Color & Learn three-cups page: the three setups from the unit, running side by side.
Try this
For each cup, predict before it plays: which way does the water move, and what happens to the cell? Score yourself against what the animation shows.
