Potato and Osmosis Investigation

1. Planning

Aim: Investigating the effect of different concentration of surcose (sugar solution) on the amount of osmosis activity between the solution and a potato chip of a certain size.


Osmosis is defined as the movement of water across a semi-permeable membrane from an area of high water potential (low solute concentration) to an area of low water potential (high solute concentration). The molecules will extend to diffuse until the locality in which the substances are discovered reaches a state of equilibrium. In this experiment of osmosis, I think that the lower the sugar solution is the large the mass of the potato will be.


To have more accurate results and create a fair experiment. Ihave selected to alter the engrossment of the sugar solution. That will give me different result to conclude. The controlling variable will be the room temperature, i chose to leave it in a bath of 37 degrees, since osmosis may occur produce various results in different experiments.

Planned method:

A range of sucrose sugar solutions will be prepared with concentrations  0.4M, 0.8M and also distilled water, two for each concentration. The potato chips will be cut using a scalpel and will be measured using a ruler to have accurate results. The six potatoes will be placed in each test tube, and therefore filling the test tube with various sugar concentrated solutions up to 9ml. The experiment will then be placed in a temperature bath, keeping it at 37 degrees Celsius.


1. Prepare the concentrated sugar solution (sucrose), 0.5M, 1.0M and distilled water.

2. Get six equally measured (1.5cm) potato chips.

3. Place them in to fifteen test tubes.

5 for each with 3 different concentration

4. Pore the solution into the test tubes until it reaches 10ml ...
