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 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 guides the analysis of a published scientific figure from a study that investigated how salt affects the electron transport chain.

This activity accompanies the video Seed Dispersal and Habitat Fragmentation. Students use data from published studies to understand patterns of seed dispersal and apply these ideas to the design of a conservation area.

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 explores images of plant cells and structures, which serve as phenomena for learning about how plants respond to stimuli.

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 activity guides the analysis of a published scientific figure from a study on prehistoric human food sources. In this study, scientists used carbon isotopes to determine how the advent of agriculture affected human diets.

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).

In this activity, students further explore the short film Popped Secret: The Mysterious Origin of Corn, by working through the mathematical concepts behind George Beadle’s claim that teosinte is the wild ancestor of maize.

A number of questions are embedded within the short film Popped Secret: The Mysterious Origin of Corn, which explores the genetic and archaeological evidence that corn was domesticated from a wild Mexican grass called teosinte.
