In Science class we've been learning about cells and what they do in a living body. Some cells are good but others can be bad, like cancer cells. We did an egg lab, where we measured the outside of the egg and put it in different liquids. This lab taught us about the cell membrane. The job of the cell membrane is to either keep things inside the cell or keep other things out. One thing I've learned that is really neat is how cells multiply. They kind of just cut in half but both new cells are the same as the original cell.
