Lab day 1: Gummy bear Osmosis GUMMY BEARS · DIFFUSION: Diffusion is the random movement of molecules. · OSMOSIS : Osmosis is the diffusion of water molecules in and out of the membrane of the cell The water can be in one of these situations: 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 and see what has happened. When we look at the next day we can see some changes The colurless one has swell. This is because the water had less concentration (hypotonic) and tried to compensates the concentrations by entering the bear. The red one has shrink. This is because the water had...
