Sound: Travel through Materials/ Research Echolocation

Click on the add response. Watch the video on how sound travels through air, water and solid materials. Research an animal and how it uses sound to locate things. This is called echolocation. Bats, whales, dolphins, some shrews, a few birds like the nocturnal oilbird and some swiftlets, for example, use echolocation to hunt, navigate where they are going and to communicate with others. Write a brief paragraph explaining the animal you have chosen. What material do they use for echolocation (air, water, or solid) and how does echolocation benefits the animal. Use the notes portion of Seesaw. When you are finished, click the green check mark to send to your teacher.
