Echolocation

My first grade scientists are studying nocturnal animals. After learning that we need light to see, we paired up and turned on and off the overhead lights while we watched our pupils change size.

Shhh! Don’t wake up the lab bats!

 

Then we learned how bats use echolocation to locate their prey. We are investigating how echolocation works in the pictures below.


Sonar is modeled after echolocation.
