LAB DAY 1: Gummy bears osmosis
·GUMMY BEARS
·DIFFUSION: random movement of molecules.
·OSMOSIS: diffusion of water molecules in and out of a cell.
→ Hypertonic: more concentrated.
→ Hypotonic: less concentrated.
→ Isotonic: same concentration
EXAMPLE:
We have three gummy bears, one is red, anotherone is colorless, and the last one is yellow. We put the red one in salt water, the colorless one in normal water and the yellow one in honey; and we leave them for 1 day.
At the next day, we can see that they have changed. This is becouse osmosis.
The red one is smalller, the colorless one is bigger and the yellow one is the same
