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 reaction occurring because of the osmosis. After a three day wait the eggs will be in their final stage or transformation. Using the eggs for showing osmosis is simple because we can see what is happening to the eggs membrane. During this process thee egg also only allowed certain substances to be able to pass through its membrane while at the same time blocking others from entering. Using clear containers allowed us to watch the eggs response with each of the vinegar, karo syrup, and water. Hypothesis: This isn’t my first time doing this lab. Trying to remember from my science class in middle school I knew that the shell woud turn into a rubber like texture and I think the egg will weigh less with the vinegar and weight more when using the syrup. When using the water I think it will break down the egg. Initially I figured the egg would absorb the substance they were being submerged in. I assumed the eggs would get bigger. This being my first time I was completely excited to see the end product. Materials:

Food Scale capacity of 6.6 lbs ( or postal scale)
1 Large bottle of vinegar
1 bottle of Karo (clear)
2 raw chicken eggs
1 bowl
4 clear glass cups
2 Bottles of water

Method:
Day 1: On day one weigh the egg being used for the experiement with a scale that can measure in grams and document the weight. Place your egg in the cup you will be using making sure that you don’t break it. Place enough vinegar in the cup to be able to cover the...
