Osmosis - Plan Input Variable: Strength of water/sugar solution. Controlled: * Type of substance (in this case a potato chip). * Size of potato. * Conditions i.e. they are all in the same light and heat. * Volume of solution. Outcome: The change in length/mass of the chip. Prediction - I predict that the stronger the solution (external) the more the potato chip will lose mass due to osmosis. I have based my prediction on the theory of osmosis. When plant cells are placed in water, the water enters the cells. Each cell is surrounded by a cell membrane. It separates of the cell from the outside. The cell membrane has tiny holes in it. This allows small molecules to pass through but not large ones. The cell membrane is partially permeable. Osmosis is a special kind of diffusion to do with water molecules. It occurs when two solutions are separated by a partially permeable membrane. The stronger...
