Today in class we made a hydrometer. I added a lot of rocks to the hydrometer and had clay on the top. It floated in the water. It was difficult to get some of the rocks into the hydrometer and to get it standing straight up to measure. You can use the tool to find the density of various liquids.

Today in Biology, we learned to use a microscope. My lab partner and I examined a leaf under 40x. We were able to see how many cells there are and how little the cells are.
