As discussed in the intro‚ the purpose of this lab is to observe principles of homeostasis and osmosis in action. The results of this experiment showed that eggs placed in a 4 M sucrose solution lost mass over time and had the greatest percent difference in mass compared to the eggs in other solutions‚ with the 4 M egg having an average of -25.13% difference in mass. The 0.0 M solution egg only had a 12.28 average percent difference in mass‚ the 0.5 M egg with 10.39%‚ and the 1 M egg with the least

Title: Egg Osmosis Purpose: The purpose for doing this lab is to show how Osmosis takes place. It is supposed to show how the eggs would react to a change in their environment. The way to show how it would change would be putting eggs in different controlled environments. Each of the eggs will be put in three different environments. Vinegar‚ Karo Syrup‚ and water. Each egg will have to have a documented reaction that each will have. Introduction: The lab will allow us to see and explain each

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
