------------------------------------------------------------------------

Equipment:

  • 4x Gummy Bears of the same color
  • 2x Petri dishes
  • Paper towels
  • Marker pen
  • Water
  • Sugar water
  • Salt water
  • Electronic balance
--------------------------------------------------------------------------

Inscutions:
  1. Get you equipment.
  2. Put on you safety glasses.
  3. Using the marker pen, write the name of the condition on the petri dish. DRY, WATER, SALTWATER, SUGAR WATER.

Discussion

  1. The normal water was transferred.
  2. The dry gummy bear lost 0.11g.
  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.
