1. Light Microscopes
Light microscopes use a light that reflects through the stage of a microscope.
The correct way to carry a light microscope is by keeping one hang on the arm and one hand underneath the base. The microscope should rest against your body.
If you cannot show that you know how to properly transport a microscope then you will no longer be allowed to use it in class. 

2. Why use light microscopes?
We use light microscopes to see cells.
This week, we will be focusing on cells, their parts, and how to classify cells.
Parts of the Cell Theory include:
- All living things are made of cells.
- All cells come from preexisting cells.
- Cells are the basic unit of life.
The first person to discover cells was Robert Hooke.

3. Parts of the Microscope and Their Function
On the next slide there is an image of a microscope, very similar to the scopes we use in class.
Click on the boxes to see the name and function of each part of the microscope.
