Echolocation in Action! Activity

Animals — such as bats, whales and dolphins — use sound to see by emitting sounds that echo off other objects and then return to their ears. Depending on how long it takes the sound to reach their ears and the direction it comes from, these animals can determine the location of the object.

Engineers have mimicked this natural echolocation in Sonar and Radar, which work basically the same way as echolocation in animals.

In this activity, students will try to determine the location of nine sounds made from various locations in front of, behind or to the side of them. Try to spread students out as much as possible so that each team can focus on their own clapping or snapping noises without being distracted by other teams. Conducting this activity outside or in the school gym is an excellent idea.
