What can scientists learn about whales by listening to their sounds in the sea?
This 3-day investigation begins with students listening to a variety of underwater sounds, and deciding if the sound was made by an animal or something else. They learn about sound and how sound works in water, and about a researcher in the Bering Sea who is using sound to study the North Pacific right whale. Students learn about hydrophones and participate in an activity that simulates the use of hydrophones. Finally, they learn about spectrograms and try to identify animals by looking at the spectrograms and listening to the associated sounds.
