Gummy Bear Experiment

When you start you should have put the gummy bear in the water and the other in the plastic bag. The one in the water at the beginning of the experiment had a thickness of 9mm a width of 11mm and a height of 22mm and it had a total mass of 2.59grams and a total volume of around 2178 mm 3 The one in the plastic bag is going to be the constant It massed at 2.53 grams and had a height of 21mm a width of 12mm and thickness of 11mm and a total volume of 2772mm3 . We left ours in the water for 24 hours but the one in the bag did not fully diffuse. Because of the semi-permeable membrane that allows certain molecules to get in such as water. Osmosis allows the movement of water to get past the membrane in a cell so that it may get high concentration to low concentration.
After we took that gummy bear out of the water the size of it had changed dramatically the thickness was 25mm the width was 18mm the height was 41mm and the final volume was 18450 mm 3 and that final mass was 13.28grams. Overall we could tell that there was a lot of osmosis and diffusion happening to the gummy bear. If we were to make this experiment better I would suggest leaving the gummy bear in water till it was fully diffused. Another way we could make this experiment better would be to use more expensive gummy bears so that they would not fall apart so easily. Overall I liked the experiment and thought that we got good data it was also fun seeing how much diffusion accord with our own eyes not just the smell of it
