Grade 7 - Project

"EggsSperiment With A Cell"

    One of the cell structures you will be learning about in Chapter 1 is the cell membrane.  In the Chapter 1 Project, you will model how a cell membrane works to let water enter and leave the cell.   You will use a chicken egg as a model of a cell.  After dissolving the shell in vinegar to expose the membrane, you will soak the egg in various liquids and observe how the size of the egg changes as it takes on or loses water through the membrane.   You also will keep a daily record of observations and measurements of the egg.
