A GCSE essay on the effects of osmosis on potato chips in different molar solutions

Introduction: Osmosis is a special kind of diffusion. Diffusion is the movement of particles from a high concentration to a low concentration until they are spread out evenly. Osmosis is the passage of water molecules from a region of high water concentration to a region of low water concentration through a selectively permeable membrane. The diagram below shows how water molecules move through the selectively permeable membrane from the region of high water concentration to …

…increased. How accurate are my results? My results are quite accurate, however they are not totally accurate because some of the chips are slightly different masses, also to find the average mass I had to find the mean of the three masses. This meant that the results were slightly off but they are not off enough to make much of a difference as you can see because the points on the graph follow a pattern.
