Life at Risk - Teacher's Guide

Episode Overview

In segment one Patrice looks at some of the factors that could endanger plant and animals species. Then she joins Dave to learn about the wood turtle. Next, we take an up-close look at the peregrine falcon. Finally, Sarah and Octave join Susi von Oettigen of the U.S. Fish and Wildlife Service as she monitors the health of dwarf wedge mussels.

Program Objectives

Students will:
1. Understand the species diversity helps maintain healthy ecosystems.

2. Define extinction.

3. Define endangered.

4. Name some species that are extinct or endangered.

5. Describe how changes in an environment can lead to extinction.

6. Explain the role of adaptation in extinction.

7. Describe way humans have contributed to species extinction or endangerment.

8. Recognize the distinct characteristics of the peregrine falcon.

9. Explain how the peregrine falcon was almost eliminated and how it came back from possible extinction.

Vocabulary

Endangered	Extinct
Threatened	Invasive

Previewing Activity

Using the blackboard or a wall chart, have students brainstorm factors that they think could endanger plant and animal species. When the list is done, have the student categorize the factors as natural events, human impact, or a combination of both.

Post-Viewing Activities

1. Using the list generated for the previewing activity, have students further discuss the factors on the list and identify animal and plant species that have been impacted by those factors.

2. Have each student research a plant or animal species in their state that is endangered or threatened. During their research students should identify factors that are impacting the species and identify efforts that are being made to help the species. Have them also develop other strategies for saving the species.

Hands-On: Get Active

Materials Needed

research on local endangered or threatened plant or animal species.

Process

In this activity the class selects a plant or animal species that is threatened or endangered in their area and then designs a public relations campaign to raise awareness of the plant or animal's plight.

The class should research the plant or animal and discover what is threatening it and develops a strategy for the best way to educate people about the plant or animal's status and things they can do to help save it. The campaign could involve letter writing, a poster campaign in the school or community, cleaning up the animal or plant's habitat, talking to local press, raising money or a variety of other activities.
