Osmosis Experiment

Osmosis is the diffusion of water from a dilute concentration to a more concentrated solution. In all things, everything moves from high concentration areas to low concentration areas, when in water, this process is called 'Osmosis'. With potato (plant) cells, it swells up as water enters through osmosis, however, it won't burst because the cell wall is tough, and it only stretches out slightly.

Aim:

The aim of our experiment is to see how osmosis affects the shape or mass of the potatoes.

Method:

We cut up some potato with a cork borer and put 5 bits in salt solutions and 1 in a beaker of water. We took the weight before it went in the solution and left it with Clingfilm over the top of the beaker for a day. We took the weight again to see how much it had changed.

Prediction:

I think that the potatoes in the high concentration will weigh more after osmosis because it would have absorbed more of the solution.

To make it a fair test we made sure we used the same amount of water in each beaker and put the
