Online Resources

See the following Web sites for appropriate laboratory activities:

1. In these lab activities, students will isolate and culture bacteria in food or soil. (Lesson 13.1)

2. This lab challenges students to simulate a virus outbreak and conduct an epidemiological study to locate “patient zero.” (Lesson 13.2)

These Web sites may also be helpful:

1. Several microbe worksheets, activities, and other classroom materials are available at this URL.

2. This Web site from the CDC has a diversity of materials for the classroom pertaining to microbes and epidemiology.

3. This Web site is suitable for advanced students. It describes engineering solutions for remote sampling of extremophiles and PCR analysis of their genomes.
