SEM Microscopes

How do you see more detail and objects that are too small to be seen with a compund light microscope? To learn more about powerful microscopes that can see the beyond the capabilities of the compund light microscope go to:

How the SEM WORKS

Imaging Technology Groups Images from SEMs

MicroAngela SEM Antics (Animations from SEMs)

Complete one or more of the following activities:

1. Tell what SEM stands for and draw and label 3-4 images as seen through an SEM.
2. Tell what SEM stands for and draw an SEM and label the parts
3. Make a VENN diagram telling the similarities and differences between an SEM and a Compound Light Microscope (the kind we use in class).
Use the following categories in your VENN Diagram:

Magnification range
Method of magnification
Dimensions (2-D, 3-D) of images
Color of images
Sample preparation
Parts of each microscope

4. Determine how SEMs can help scientists and doctors diagnose and treat disease.

5. If you could look at something under an SEM (that is not already shown on one of the websites), what would it be? Why? Draw what you think the magnified image would look like.
