Evolution – Diversity of Life
Scientists noticed animals with backbones share similar bone structure despite having different forms, such as fins, arms, and wings. Young scientists gain an appreciation for evolution by understanding the history of the theory. They...

Population Genetics
Genetic variation shows the health of a population, yet cheetahs show very little variation over that last 10,000 years. Scholars learn the importance of genetic variation in populations after viewing an informative presentation. It...

The Ecology of Lyme Disease
Areas that previously included no risk of Lyme disease now have cases every year. Scholars learn about the spread of Lyme disease and the relationship with ecological succession. Then, they discuss possible solutions using the known food...

The Value of Behavioral Variation in Homo sapiens
Students look at the behavioral characteristics of their peers from a historical perspective, and realize that, in the larger scheme of a community, these behaviors do have some value, and that a society as complex as ours does need the...
