In this collaborative activity, students explore major biodiversity threats and design, present, and refine solutions for preserving biodiversity.

In this activity, students engage in key science practices that scientists used to figure out ecosystem dynamics in the Serengeti.

This activity explores images of elephants with and without tusks, which serve as phenomena for learning about selection and human impacts on the frequency of traits within populations.

In this activity, students evaluate a science news article to determine whether it is a trustworthy source of information.

In this activity, students find a scientist with whom they can relate in some way and then explore and reflect upon the impact of that scientist’s work.

This activity guides the analysis of a published scientific figure from a study that investigated how gene duplication contributed to the evolution of electric fish.

This activity guides the analysis of a published scientific figure from a study on how adversity in early life impacts the long-term survival of baboons.

This interactive module explores the biology of sex determination and development in humans, set against the backdrop of the different sex testing policies implemented throughout sports history.

This activity supports the film Popped Secret: The Mysterious Origin of Corn. Students analyze data on the expression of the tb1 gene to explain how variations in this gene played a role in the evolution of corn.

This activity analyzes a published scientific figure from a study that investigated the biological importance of sleep. In this study, scientists tested whether sleep plays a role in removing harmful substances from the brain.

This interactive module allows students to examine evidence from brain anatomy, tissue histology, and genetic studies to identify possible targets for the treatment of Alzheimer’s disease.

This activity guides the analysis of a published scientific figure from the world’s longest-running controlled artificial selection study, in which scientists tested whether they could use selective breeding to change the protein concentration of maize (corn).
