Overview

The oceans are filled with many unusual invertebrates. This lesson will explore these organisms and the means by which they survive in and adapt to their watery environment.

Major corporate support is provided by Canon U.S.A., Inc. and Ford.

Subject Matter

Life Science, Living Environment, or Biology


Learning Activities

Students will be able to:
  • identify the difference between invertebrate and vertebrate organisms.
  • identify various types of invertebrates and place them in zoological classes.
  • create a food web of these organisms.
  • describe how human activity can impact the oceanic environment through off-shore drilling, pollution and fishing.

Standards
