Microscopes: e Lab

e

Cut out a lower-case letter e from a newspaper. Create a wet mount slide by placing the e on a slide, placing a drop of water on the e, and dropping on a cover slip. Place the slide on the microscope, so that the e is facing you, as you would read it. Draw what you see through the microscope. Move the slide to the right as you watch through the eyepiece, to the left, up and down.

This is a great introductory microscope lab for students. You can easily determine if students are accurately drawing what they see through the microscope or just drawing what they think they are supposed to see.
