9-7. Discuss your feelings about the Tuskegee experiment and relate the Tuskegee experiment to the current concern about how to ensure that AIDS vaccine testing does not unfairly exploit high-risk groups.

Activity 10

10-1. Examine the general shape, color, and structure of the fungal colonies.

10-2. Create slides of the fungi grown in the cultures.
