Echolocation in Action!
In this activity, students will experience echolocation themselves. They actually try echolocation by wearing blindfolds while another student makes snapping noises in front of, behind, or to the side of them.

We need to know where things are, and many times we need to be able to "see" something even when it's dark outside or something is far away and obstructed by the ocean or clouds. Engineers have learned from nature how to use sound and radio waves to locate objects. This is called SONAR (SOund wave Navigation And Ranging) and RADAR (RAdio wave navigation And Ranging).
After this activity, students should be able to:
- Explain the basics of echolocation.
- Explain that engineers developed SONAR based on natural echolocation.
