Things to Know…
Essential Question:
Would discoveries have been made if the microscope was not invented?
Objectives:
Demonstrate the proper use of the microscope
Illustrate the parts of the microscope
Terms to know!
Magnification:
The action or process of magnifying something or being magnified. Your microscope has 3 magnifications: low, medium and high.
The total magnification is the eye piece x objective

Zacharias Janssen in the 1590’s created the “first” compound microscope.
I created the first microscope by placing two lenses on top of one another to make extra-large images.

What did Hooke see when he looked at cork?

Types of Microscopes:

Parts of the Microscope
Eyepiece:
Always 10X
Where you look through to see the image of your specimen
Body Tube
Long tube that holds the eyepiece and connects it to the objectives
Parts of the Microscope
3. Arm:
Part of the microscope that you carry the microscope with
Nosepiece:
Rotating part of the microscope at the bottom of the body tube; it holds the objectives.

Parts of the Microscope
6. Stage Clips:
clips on top of the stage which hold the slide in place
5. Objectives:
Low, medium, high, Helps magnify the image.
4X, 10X, 50X

Objectives
What happens as the power of magnification increases?
Learning Check No 1 (5 minutes- elbow partner)Copy the numbers and the magnification formula and calculate the magnification of the next objectives.
Parts of the Microscope
Stage:
Black flat area under the objectives.
it has a hole in it (see aperture) that allows light through; the specimen/slide is placed on the stage for viewing.
Parts of the Microscope
Coarse Adjustment:
Large, round knob on the side of the microscope used for focusing the specimen
Parts of the Microscope
Diaphragm:
Controls the amount of light going through the aperture
12. Light Source:
Source of light usually found near the base of the microscope; the light source makes the specimen easier to see
Parts of the Microscope
13. Fine Adjustment:
Small, round knob on the side of the microscope used to fine-tune the focus of your specimen
Use it after using the coarse adjustment knob
Parts of the Microscope
Base:
Hold the components to the microscope

Drawing Specimens
Use pencil
All drawings should include clear and proper labels (and be large enough to view details). Drawings should be labeled with the specimen name and magnification.
3. Labels should be written on the outside of the circle. The circle indicates the viewing field as seen through the eyepiece.
Notice the 3 parts:
