Online Resources

See the following Web sites for appropriate laboratory activities:

3. Students can investigate behavioral responses to stimuli in insects using materials at either of the two URLs below. (Lesson 20.4)

4. You can choose from several online animal behavior labs at this Web site. Topics range from constructing ethograms to studying the human behavior of weight lifting. (Lesson 20.4)

These Web sites may also be helpful:

1. The Web sites below are searchable online field guides that you and your students can use to find descriptions and photographs of mammals. They are good sources of examples when you teach this chapter.

2. This American Museum of Natural History online exhibit provides virtual tours, videos, interactive activities, timelines, and articles on living and extinct mammals. It focuses on mammalian adaptations and evolution, and includes both student and teacher pages.

3. This Web site suggests a variety of videos, activities, and discussion topics that relate to animal behavior.

4. Students can follow the field research of zoo scientists studying applied animal behavior by reading their online field diaries. The Web site also offers articles, videos, and activities.

5. This issue of the National Science Teachers Association monthly newsletter focuses on animal behavior. It contains articles and links that are useful for both teachers and students.
