Recall that the function of the cell membrane is to control the internal balance of the cell. It helps to maintain homeostasis. In this lab you will use vinegar, an acid, to dissolve the shell off of the egg to expose the membrane. When you place the egg in water, you will be able to observe osmosis in action over the next few days. Remember to handle the egg with a lot of care and don't forget to wash your hands each time you touch the egg.
Keep Moving! This lab activity takes 3 days to complete. Once you have this lab set up, go to the next assignment.
Here is the plan.
