When diffusion occurs, molecules move from a higher concentration of water towards a lower concentration of water. Mechanism by which substances are moved from the cell interior to the extracellular space as a secretory vesicle fuses with the plasma membrane. If the water outside the cell has LESS water than inside, water will move from the inside of the cell to the outside. Add 1 ¾ c of salt to 1 liter of water, 2.

If the H2O concentration in salt water is (higher / lower) than the H2O concentration in a Gummi Bear, then Gummy Bears placed in salt water will (increase/decrease/ remain. Measure the gummy bear’s volume as an irregular shaped object; fill up a graduated cylinder with a certain amount of water, place the gummy bear in the graduated cylinder, and measure the difference in milliliters. 6. This means that the gummy bear will shrink more if the salt water solution is of a higher concentration. ★ ★ Gummy Bear Osmosis Lab ★ ★ Students will observe the effects of osmosis on a gummy bear in this guided scientific method lab report. They finished the lab by writing down their conclusions on the lab sheet.
