Plan In my experiment I plan to find out whether the concentration of sugar in water affects how much water will go in to a potato chip I will do this by having twelve test tubes three with one molar of sugar solution three with molar sugar solution three with molar sugar solution and three with zero molar sugar solution I will do three of each so I can take an average from the results Prediction For the investigation I think that the lower the concentration of sugar in the test tube the larger mass the potato chip will be I think this because I know that Osmosis is the movement of water molecules across a partially permeable membrane from an area of high water concentration to an area of low water concentration Therefore the water molecules pass from a high concentration in the water itself to a low concentration in the potato chip Therefore the chips in higher water concentrations will have a larger mass than in higher sugar concentrations Diagram For Prediction This is a diagram for what I predict will happen in the experiment If the potato is in one Molar solution then the increase in mass due to osmosis will be little as there is more sugar than water in the solution If it is in 05 Molar solution it should increase a little If it is in pure water then the increase will be quite a lot as there are many water molecules in water therefore due to osmosis its mass will increase more that the other two experiments Fair Test In the investigation I will make it a fair test by keeping the following things the same 1 Volume of solution 20ml 2 Same size boiling tube 3 Same type of potato 4 Temperature Room Temperature 5 Same sugar solution 6 Same size potato borer
