1. SC.912.L.14.4 TYPE AND FUNCTION OF VARIOUS MICRSCOPES Compare and Contrast the structure and function of various microscopes

2. Why do we use a microscope? Many things are smaller than we can see with the naked eye. To accurately study Biology we need a tool to help us see these tiny things.

3. Types of Microscopes Binocular Compound Microscope A compound microscope is one that has two lens, usually one in the eyepiece and another that can be varied. These have a magnification of up to 1000X. Stereo Microscope A stereo microscope has a magnification of about 10 X. With a stereo microscope you can look at the details of larger objects. For example, an entire leaf or the whole body of a spider.

4. Electron Microscopes Objects smaller than 0.2 um can be seen with an electron microscope. (Viruses, internal cellular structures)

5. Scanning Electron Microscope Image appears in 3-dimensions and in black and white. The magnification is usually 1000X to 10,000X. It is particularly useful for studying the surfaces of cells and viruses.
