1. The scanning electron microscope provides a different
type of image than the conventional electron microscope. Conduct an Internet
search to find out how the two microscopes are different from one another.
In your research, find out how the scanning electron microscope is able
to scan an object and produce an image and what its resolution and magnification
limits are. Prepare a multimedia presentation with diagrams of how the
microscope works and sample images to inform your classmates of what you
have learned. Below is a web site to get you started:
Museum of Science™, Boston: Scanning Electron Microscope

2.High-contrast microscopy has different uses, magnification,
and resolution than the ordinary light microscope. Conduct an Internet
search to find information about high-contrast microscopy. In your research,
find answers to the following questions:
a.How is the high-contrast microscope different from the
standard light microscope?
b.What type of light source does it use?
c.How are samples prepared?
d.What types of objects are best viewed using high-contrast microscopy?
e.What special features might it have?
Prepare a multimedia presentation, with diagrams of how the microscope works
and sample images, to inform your classmates of what you have learned.
