Author: James Trodden Hands-on Activities Using the Microscope I always start my microscope unit by first discussing the parts and proper care and handling, but before I spend to much time on this and get boring I jump into an activity. Using a newspaper I have the students cut out a letter,(e works the best)using the microscope they then focus in on the letter. It is easier to teach microscope skills with the letter than any other material. Students then focus on it at higher magnifications. Students become facinated by actually being able to see the individual dots that make up the letter. In the next lesson I use an onion as the material to look at. The best cells from the onion are achieved by peeling back a layer, on the inside a thin layer of tissue can be removed from the onion that is transparent and works well. Be sure to wet mount( place in a drop of water) the onion cell or it will dry.
