Purpose:

The purpose of this lab is to learn about different types of microscopes that we use today, learn the parts of the microscope, and how to properly use a microscope by exploring various slides.

Materials:

*Microscope
*Letter “e” slide
*Onion root slide
*Bacterial capsule slide
*Cheek smear slide

Lab Notes:

1.What is the difference between a compound microscope and a stereo microscope?
Be detailed.

Compound microscopes and stereo microscopes are different in a few ways. The compound microscope can provide a magnification up to 1000X. It is better suited to view smaller objects such as animal tissue and thin pieces of plants. The stereo microscope on the other hand is able to view much larger objects such as rocks, insects, and flowers. However, the stereo microsope has a much lower magnification range of only.

2.If the ocular of your microscope is 10x and your objective that you are viewing your specimen under is 10x, what is the total magnification?

To find the total magnification, you will multiply the ocular of your microscope by your objective. This results in the total magnification being 100x.

3.How does the light change on the compound microscope?

Light on the compound changes from adjusting the iris diaphragm

4.What is the magnification of the ocular? The magnification of the ocular is 10x.

5.Which type of microscope could you view a Frog?

A stereo microscope would allow a person to view a frog.

6.What is the circular area that you see when you look under the microscope?

The circular area you see when you look under the microscope is called the field of view. 7.What happens to the field of view as you go from low to high power on a compound microscope?

When you go from low to high power on the compound microscope the field of view decreases.
