Investigation of Osmosis

Aim: I am going to investigate osmosis in plant cells by seeing how potato chips change weight in different strength sugar solutions. Introduction: 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. The tiny holes in the membrane allow water molecules to pass through. But the large solute molecules are too big to pass through the partially permeable …

…test them to see if there was a major issue. My data also fits the conclusion and the aim of my coursework was completed. The whole experiment ran smoothly so nothing had to be repeated or changed to fit in with the aims. To further my evidence I could: Test a different type of potato Cut different size chips Have chips with all different masses Change the ratio of sugar and water Change the temperature
