The lesson Risky Genetics from NOVA scienceNOW allows students in grades 9-12 to explore genetic testing for three specific diseases — breast cancer, lung disease and Alzheimer’s — and consider the pros and cons of discovering a person’s genotype for a particular disease.
Students play the role of genetic counselors who counsel patients about their genetic test results for genes associated with these three diseases. With the rolling of dice with a partner, each “counselor” creates a male or female character with a unique genotype. Other activities ask students to analyze genetic data for their “patients,” compare their characters’ risks of developing the diseases, and predict the disease risks for the next generation.
