Notes

1. The plastic bag turned purple, and then the iodine molecules passed through the plastic bag slowly and turned the water yellow. The cornstarch did not pass through at all.
2. The Iodine molecules were placed in the beaker, and turned the water yellow. Diffusion happened and it passed into the plastic bag, mixing with the corn starch and turning it a deep purple.
3. The Iodine molecules in both the beaker and plastic bag had already reached equilibrium and had no need for diffusion. The water stayed purple and the plastic bag turned yellow.
4. The iodine molecules moved from high concentration (in the plastic bag) to low concentration (in the beaker). The water in the beaker turned purple and the plastic bag turned yellow.
5. The iodine molecules moved from high concentration to low concentration, but the corn starch was in both the plastic bag and beaker, so both turned purple.
6. The corn starch tried to pass through to the plastic bag but it was no permeable to the substance, so it could not. The iodine molecules stayed in the same places. The bag turned yellow and the beaker turned purple.
7. Both the beaker and the plastic bag had equal iodine and corn starch molecules, so diffusion did not happen. Both the plastic bag and the water in the beaker turned yellow due to the mixture of cornstarch and iodine.
8. The cell membrane is selectively permeable and the plastic bag was also selectively permeable, it let the iodine molecules in and out but not the cornstarch molecules.
9. A movement of molecules between two areas where one substance has high concentration and the other has low concentration, so the substance with high concentration attempts to reach equilibrium by going into the other substance of low concentration.
10. They're either too big or the cell membrane will not allow the substance to pass.
11. They both showed diffusion between two different concentrated areas and changed the liquid (or egg) according to which had a higher concentration.
