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.

In this activity, students explore how experimental work in zebrafish led to a better understanding of the role of the gene SLC24A5 in human skin color. The activity complements the film The Biology of Skin Color.

A number of interactive questions are embedded within the short film The Biology of Skin Color, which explores the hypothesis that the variations in skin color in humans arose as adaptations to the intensity of ultraviolet radiation in different parts of the world.

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.

This activity guides the analysis of a published scientific figure from a study that investigated a gene involved in determining human skin color.

This activity explores how scientists determined how and where corn was domesticated, as discussed in the short film Popped Secret: The Mysterious Origin of Corn.

The added information provided at pause points within the animation How We Get Our Skin Color allows for a richer exploration of the topic of human skin structure and function.

This activity explores the evidence that differences in human skin color are adaptations to varying intensity of UV light, as discussed in the short film The Biology of Skin Color.

This animation describes how skin color is generated by skin cells as protection against ultraviolet (UV) radiation.

This lesson supports concepts covered in the film The Birth and Death of Genes. After watching the film and reading a couple of scientific passages, students explain how understanding about icefish adaptations might help develop treatments for health conditions.
