General Science: Plant cell and animal cells...up close and personal

Last week we continued our investigations with microscopes. Having already gotten some experience with the ins and outs of using a microscope, we focused on different kinds of cells. The kids got a chance to compare plant and animal cells by extracting human cheek cells (sounds much more painful than it actually is) and onion cells (a little smelly, but otherwise no tears). We talked about how animal cells are more "blob-like," and plant cells have a rigid exterior, which makes them look like boxes or bricks.
