Detailed explanation-1: -Why a Gummy Bear? The Gummy Bear has a selectively permeable coating which will allow water molecules to diffuse across, but inhibiting other larger molecules. In this osmosis experiment the water molecules move into the bear, thus enlarging it.

Detailed explanation-2: -The gummy bear in the lab is going to be a prime example for osmosis, which is the flow of water from an area of high concentration to low concentration.

Detailed explanation-3: -When you put a gummy bear in water, it is a solute, and the water molecules are a solvent. Since the gummy bear does not contain water (remember, the water was removed when the gummy bear was made), water now moves into the bear by the process of osmosis.

Detailed explanation-4: -A gummy bear will grow when placed in a variety of liquids by using the process known as osmosis. Since the gummy bear water was removed when it was created when a gummy bear is placed in water the water will move into the bear by osmosis.

Detailed explanation-5: -The gummy bears get bigger or smaller after soaking in the liquids because of a process called osmosis. Osmosis lets water pass in or out of a cell’s membrane in an attempt to equalize the molecules inside and out.
