Microscopes can be used to see things too small for our eyes to see.

Micro means 'small' and scope means 'small'.

A microscope is piece of equipment used to make small objects appear larger.

The parts of the microscope are shown in the diagram below:

To see an object clearly with a microscope a specimen must be prepared first.

1. A small specimen is placed on a glass slide.

2. A dye is used to colour the specimen so it can be seen more easily under the microscope.

3. A cover slip is placed on the specimen to flatten it.

4. Tissue is used to absorb any excess dye.

5. The glass slide is placed on the microscope stage.
