Detailed explanation-1: -Osmosis is the movement of water molecules from an area of higher concentration to lower concentration over a semi permeable surface. The gummy bear in this experiment will act as the semipermeable surface, allowing water molecules to flow in and out of the gummy bear.

Detailed explanation-2: -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-3: -If the water outside the cell has LESS water than inside, water will move from the inside of the cell to the outside. That is what happened to the Gummy Bear in the salt. The water had to move out of the Gummy Bear to “even out” the concentration of water. The Gummy Bear became smaller with less water to fill it up.

Detailed explanation-4: -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.
