This is the lab that I use to introduce the light microscope. The first part of the lab focuses on the proper procedures of using a microscope. Each student has to fill out the procedures section before they can start working on the field of view drawings. Once they are done then each pair of students gets a letter 'e' slide and a colored threads slide. This activity supports Grade Seven California State Science Standard 7A - Select and use appropriate tools and technology (including calculators, computers, balances, spring scales, microscopes, and binoculars) to perform tests, collect data, and display data.
