Gummy bears osmosis

LAB DAY 1 : GUMMY BEARS OSMOSIS

Diffusion: random movement of molecules.

Osmosis, is a type of diffusion of water molecules in and out of a cell, surrounded by a membrane that only allows water through.

  • Hipertonic : more concentration outside
  • Hipotonic : less concentration outside
  • Isotonic : same concentration


This day, we had to think what will happend to a :

  • Red gummy bear with a lot of salt.
  • Yellow gummy bear with honey.
  • White gummy bear with a lot of water.


My hypothesis was:

  • Red one, it will become harder.
  • Yellow one, it will become smaller and with another color.
  • White one, it will absorb the water and become harder.

The results were :

  • Red gummy bear : It lost water and become smaller. The salt absorbs the water because it has more concentration ( hypertonic ) .
  • Yellow gummy bear : Same concentration so it has the same size, but it became harder (isotonic 50 % sugar )
  • White gummy bear : is bigger because it absorbed all the water, less concentration inside (hypotonic)
