1. Introduction to the Microscope
Care
Parts
Focusing
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.

2. Microscope Care Always carry with 2 hands
Only use lens paper for cleaning
Do not force knobs
Always store covered
Keep objects clear of desk and cords

9. Using the Microscope Place the Slide on the Microscope Use Stage Clips
Click Nosepiece to the lowest (shortest) setting
Look into the Eyepiece
Use the Coarse Focus
Give students a slide from the “common things” set, each student will practice focusing and changing objectives.

10. Using High Power Follow steps to focus using low power
Click the nosepiece to the longest objective
Do NOT use the Coarse Focusing Knob
Use the Fine Focus Knob to bring the slide
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.
What can you find on your slide?
