If you have access to a microscope, then this lab is fun and easy to do. If you're in the market for a microscope, you can view our microscope recommendations here. If you've got a microscope but just haven't used it for awhile (or never), then look over the experiments here first to get you started. Cloth fibers, wool, human hair, salt, and sugar all look really different under a microscope. It’s especially fun to mix up salt and sugar first, and then look at it under the scope to see if you can tell the difference.
