You can use a microscope to examine different details of microscopic organisms.

Microscopes allow you to view objects, such as small insects or microbes, that cannot be seen with the naked eye. By magnifying the objects tens or hundreds of times the actual size, a microscope gives you the opportunity to inspect the objects and to see minute details. In order to use a microscope properly, you need to follow a few guidelines that will ensure that you will be able to clearly observe details of the object placed under lens.

1

Plug the microscope cord into an electrical outlet. If your microscope is battery powered, you will not need to plug it in.

2

Set a glass slide onto a flat surface, such as a counter or table top.

3

Wet a cotton swab, and rub it onto the inside of your mouth.

4

Smear the swab onto the middle of the glass slide.

5

Place a glass slide cover over the top of the middle of the slide, covering the area where you deposited the contents of your swab.

6

Move the two slide arms to the side on the microscope.

7

Place the prepared slide onto the shelf, and lift the slide arms over the slide to hold it in place.

8

Turn on the microscope light.

9

Place your eye over the eyepiece of the microscope. You will see a bright light with blurry objects inside it.

10

Turn the coarse tuning knob, which is the larger knob on the side of the microscope. Look through the eyepiece of the microscope as you turn the knob. You will notice that the object will begin to become clearer as you turn the knob. Once the object is clear and in focus, stop turning the knob.

11

Turn the fine tuning knob, which is the smaller knob on the side of the microscope. Look through the eyepiece of the microscope as you turn the knob. The object on the microscope slide will begin to become very clear, and will display the minute detailing on it. Once the object is clear, stop turning the knob.
