Online Resources

See the following Web sites for appropriate laboratory activities:

1. Students will model natural selection in this lab by “capturing” food using various utensils. (Lessons 10.1, 10.2, 10.3)

2. This Web site contains a large collection of population genetics labs using simple materials such as M&M's, crackers, and pop beads. (Lesson 10.3)

3. This Web site provides two different labs that allow students to explore how genetic drift causes allele frequencies to change in small populations.

These Web sites may also be helpful:

1. This Web site provides a chronology of evolutionary science, from Plato to the Human Genome Project.

2. This Web site has original articles, scientist interviews, links, and other materials for both teachers and students who want more in-depth information about many chapter topics.

3. At the URL below, you can access a wide variety of useful activities, labs, and links relating to evolution.

4. At this URL, you can find a large collection of activities on evolution.

5. This Web site is highly recommended. It provides lesson plans, common misconceptions, and many other useful resources on evolution.
