Osmosis and Scientific Method Lab Report Abstract The purpose of the lab is to see how different size potatoes have faster water movement depending on the concentration of sucrose it was placed in. We had two sized potatoes‚ 6g and 10g‚ and placed each in three different dilutions of sucrose at 0.5M‚ 0.1M‚ and 0.05M. We also placed a 6g and 10g potato piece in water to act as a control. Based on the weight percent change over 60 minutes‚ the 6g potato piece had faster water movement than the

Introduction Diffusion and osmosis are two types of passive transport. Diffusion is a random movement of molecules from an area of high concentration to an area of low concentration. Osmosis is a type of diffusion that diffuses water through a selectively permeable membrane. There were two parts to the experiment‚ the dialysis tubing lab and the potato lab. In the first experiment‚ the dialysis tubing acted as a semi-permeable membrane. A semi-permeable membrane is a membrane

these foods‚ but with others such as eggs. Egg proteins change when you heat them‚ beat them‚ or mix them with other ingredients. Being able to understand these changes can help you understand the roles that eggs play in cooking. The proteins in an egg white are twisted‚ folded‚ and curled up into a circular shape. Different kinds of weak chemical bonds keep the protein curled up tight in the water that surrounds it. When you apply heat an egg‚ you aggravate the egg-white proteins‚ and you make them
