Students study echolocation and understand how dolphins use it to locate prey, escape predators, and navigate their environment. They view a video, "In the Wild-Dolphins with Robin Williams" and see first hand how dolphins communicate. ...

Students identify the different parts of a wave. In this physics activity, students explain how animals communicate using sound waves. They discuss the effect of Navy's sonar on dolphins and whales.

Young scholars predict the shape of an unknown object by bouncing a ball on it. In this physics lesson, students relate this activity to how dolphins use echo-location to navigate. They analyze their lab result and discuss findings.

Pupils work together to discover the concept of echolocation. They examine dolphins and their behaviors. They discuss how humans could use this information to help them in their everyday lives as well.

Students examine the effects of bycatching on water environments. They discover how echolocation works. They participate in a simulation of the process to use it while walking blindfolded.
