Microscope powerpoint
The document provides instructions for using a microscope. It begins by naming the main parts of a microscope, including the eyepiece, body tube, revolving nosepiece, arm, objective lens, stage, stage clips, coarse focus, diaphragm, fine focus, and light. It then gives directions for safely bringing out, setting up, focusing, increasing magnification on, and putting away a microscope. The instructions explain how to place slides, adjust the objective lens, use coarse and fine focusing, and find specimens.

Editor's Notes
- #2 Students will have their microscopes out, for reference as we go through each of the steps. As an introduction, students will be asked what kinds of things they can do with this tool.
- #3 Teacher demonstrates how to hold the microscope, where the lens paper is located and how to use it. Students will be invited to turn the knobs and observe the stage as it moves up and down WITHOUT A SLIDE. Teacher will demonstrate how to store the microscope.
- #4 This is the exact version of the microscope used in class. Students will be identifying the parts on the microscopes at their desks as we go along and what their functions are.
- #5 Give students a slide from the “common things” set, each student will practice focusing and changing objectives.
- #6 Have students exchange slides so they can look at different things, walk them through using the high power objective to focus slides. Emphasize not using the coarse objective during this process, as it will crack the slides.
- #7 Have students exchange slides so they can look at different things, walk them through using the high power objective to focus slides. Emphasize not using the coarse objective during this process, as it will crack the slides.
