Leaf Stomatas with Nail Polish and Cheap Classroom Microscopes

http://tayaut.net/leaf_dicot.jpeg

The school year just ended but I wanted to show off what my class was able to accomplish with some cheap high school microscopes. The images below are under-leaf impressions of diocot and monocot plants which show the stomata used to control water evaporation. To avoid the preparation of slicing leaves themselves we painted a thin layer of nail polish on the underside. Peeling this dry layer off results in a mold of the leaf itself which can then be attached to a blank slide with cellophane tape.
