This video case study explores whether elephants can detect, interpret, and respond to signals delivered by underground vibrations.

This activity guides the analysis of a published scientific figure from a study that tested how bats use echolocation to adjust their hunting behavior.

This interactive module explores how different animals — elephants, birds, and bats — have evolved distinct ways of using sound to communicate.

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.

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 animation illustrates how the human cochlea, a structure in the inner ear involved in hearing, receives sound in the form of vibrations.
