Online Study Unit

Achievement Objectives:
Students will demonstrate knowledge and understanding of:

• The earthworm’s environment
• The earthworm’s body and biology
• Why earthworms are good for the soil

All about earthworms is the best website I have found to teach the anatomy of an earthworm. Study the different parts so that when you do dissect it you have an idea what to look for. Visit the other pages such as worms as recyclers, Meet Mary the Worm Woman and Visit Wendell’s cousins.
