 Discussion 

1. The normal water was transferred into the gummy bear the most.
2. The dry gummy bear lost 0.11 grams over a week.
3. The sugar water diffused faster than the salt water.

Diffusion is the movement of a substance from an area of high concentration to an area of low concentration. Diffusion happens in liquids and gases because their particles move randomly from place to place. Diffusion is an important process for living things; it is how substances move in and out of cells.
