Experiment To Show The Effect Of Concentration On Osmosis In Potato.

PLAN: To prove my prediction I will need the following:

                  Potatoes (the same potato size)

                 5 different concentrations of sucrose (1 of which is distilled

                 water)

                1 potato borer

             1 tile to cut the potato

             Ruler

SAFETY: I will make sure that my experiment is safe by wearing goggles where necessary and making sure that I do not spill any liquid.

Making my experiment fair: I am going to make sure that I use the same volume of sucrose solution in each boiling tube. The volume that I will use will be 20cm cubed. I will make sure that the potato chips are the same size and mass. I will make sure that I will use the same size of boiling tubes and borer. The thing that I will change in my experiment is a concentration of sucrose.

What will effect my experiment: Effectors that will effect my experiment.

The temperature of a room will effect my. So I will do the experiment in the temperature and record the temperature of each solution to make sure that they are the same. It is possible that the type of potato I will use will effect osmosis. I will therefore use the same type of potato.
