Online Resources

See the following Web sites for appropriate laboratory activities:

In this lab, students learn how to use a light microscope and analyze evidence from a forensic mystery.

Students prepare wet-mount slides of the aquatic plant Elodea and view them under the light microscope. Then they investigate the effects of solutions of different concentrations on the shape and size of the plant’s cells.

You and your advanced students can learn more about specific topics in cell biology with the searchable college textbook at the link below.
