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
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. Teacher will demonstrate how to store the microscope.

3. Microscope Parts Eyepiece:
Contains a magnifying glass – ours magnifies 10X
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.

4. Microscope Parts
Arm:
Supports the body tube; carry the scope with one hand on this and one on the base
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. Microscope Parts Revolving Nosepiece:
Holds the objectives and can be rotated to changed the magnification
Scanning = 4X
Low power = 10 X
High power = 40 X
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.

6. Microscope Parts Objective Lenses: Provides magnification:
scanning objective
low-power objective
high-power objective
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.

7. Microscope Parts Coarse Adjustment:
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.
Moves the body tube to focus the image; moves quickly

8. Microscope Parts Fine Focus:
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.
Fine Focus:
Moves the body tube slightly to sharpen the image; moves slowly

9. Microscope Parts Stage: Supports the slide being observed
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.

10. Microscope Parts Stage Clips: Hold the slide in place
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.
Hold the slide in place

11. Microscope Parts Diaphragm:
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.
Diaphragm:
Opens and closes the diagram; allows more or less light to come through

12. Microscope Parts Light: Produces light so you can see through slide
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.
Light:
Produces light so you can see through slide

13. Microscope Parts Base: Supports the microscope
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.
Base:
Supports the microscope

15. Using the Microscope Place the Slide on the Microscope Use Stage Clips
Allows start with scanning objective
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.

16. Using High Power Follow steps to focus using low power
Click the nosepiece to the high power objective
Do NOT use the Coarse Focusing Knob on high power!
Use the Fine Focus Knob to bring the slide into focus
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.

17. When Finished With Lab Click the nosepiece to the scanning objective
Use the Coarse Focusing Knob to move lens all the way down towards stage
Wrap cord around base
Replace dust cover
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.

18. Calculating Total Magnification
Multiply the eyepiece (10 X) and the objective lens magnification (varies) Example: Objective lens magnifies 50 X. What is the total magnification?
