Microscope
A microscope is an instrument for viewing objects that are too small to be seen easily by the naked eye.
Micro - means very small.
Scope - is a device to look at something.
Uses more than one lens - the image magnified by one lens can be further magnified by another.

3. 4 Types of Microscopes
Simple
Compound
Stereoscopic
Electron

4. Simple Microscope
Similar to a magnifying glass and has only one lense.

5. Compound Microscope
Lets light pass through an object and then through two or more lenses.

6. Stereoscopic Microscope
Gives a three dimensional view of an object. (Examples: insects and leaves)

7. Electron Microscope
Uses a magnetic field to bend beams of electrons; instead of using lenses to bend beams of light.

8. Using the Microscope
Place the smallest objective lens over the hole in the stage.
Place the slide on the stage and fasten with the clips
Turn the coarse focus knob to make the objective lens as close to the stage as possible without touching the slide. 
Look into the eyepiece lens
Turn the fine focus knob until what you see is clear.

9. What happens as the power of magnification increases?
We can see better details with higher the powers of magnification, but we cannot see as much of the image.

10. Microscope Stations
Start at the station that matches your group number. Take turns:
Look at a specimen under the microscope. Draw what you see.
Go to class webpage, to Science>Cells, click the link for Microscope Diagram. Label the microscope diagram on the laptop.
Do the word scramble on the back while you wait.
Finish coloring and labeling your cell diagrams.
Move to the next station when directed.

11. Mystery Pictures Stations
Stations 3, 6 and 9 contain Mystery Pictures of objects that were taken with a microscope camera.
Look at the photos with a partner.
Try to identify what they are!
If you finish early, work on the word scramble on the back.
