Seeing in the Dark: Using Sound To Navigate Science Hall

	Here, Lawrentian Jodi Sedlock helps demonstrate how to find a building blindfolded using echolocation.
Here, two blindfolded GEMS students find where the building is located using echolocation with clickers.
	This is a close up view of the clickers used for echolocation.
We pretended to be like bats and used clickers to determine echos if we were standing in front of a building or open space. The clickers told us where we were!

During the lecture we were taught different and interesting things about bats. We learned about pitches, and how they find their prey with echolocation. We also got to see some dead bats that Jodi had brought back from the Philippines. All in all, this session was fun and educational!

Ask Me Questions:
Why can you hear echoes of short sounds better than long sounds?
If you are a bat that needs to detect prey far away, should your "voice" be high or low?
