Definition of Osmosis Osmosis is the movement of water molecules across a partially permeable membrane from a region of high water concentration to a region of low water concentration. Hypothesis I predict that the lower the concentration of the sugar solution in the test tube, the larger the mass of the potato tube. I think this because, during osmosis, the water molecules pass from a higher concentration, which [in this case] would be the water in the test tube, to a lower concentration, which, in this case would be the potato tube. Therefore the tube/s in...
sure it was well away from other people, I made sure that I handled the test tubes carefully so they did not break; I made sure that I did my experiment in a space so that I would not collide with other people.

3 Improvements for future

In the future, I could improve by repeating the experiment more often, showing more examples of osmosis, i.e. other experiments and giving more background knowledge to show how much I know already about the topic.

I could also plot more graphs which would increase my plotting skills.
