Do you remember how cool it was looking through microscopes when you were in school? I remember being in 7th grade and going into a small lab room filled with microscopes. We would all stand there in the dark observing all the cool stuff we could find in a few drops of pond water. It is amazing to me how many little critters live in just one tiny (gross!) drop. It also makes me want to wash my hands- a lot. The pond water lab has always been one of my favorite labs to do with my students every year. I enjoy hearing them squeal over what they see swimming around in their drop, and I don't even mind when they go through an entire bottle of hand sanitizer!
