A 3rd grade science fair project: Which bat ears hear the best?

Blood sucking bats are scary creatures of the night, right? Well, here in the Sonoran Desert bats are just curious animals to watch. Did you know that bats are the only mammals that can fly?

Bat Bridges

Many summer nights I find bats swooping over my swimming pool for a nice sip of water. And, every once in a while my family heads over to one of the “bat bridges” in town that house thousands of bats during the day. They are just regular car bridges that bats have decided to use as their summer home.

You can hear the bats high-pitched chirping as you walk under the bridge, even though you can’t see the bats hiding in the cracks.

Then, all of a sudden, it’s feeding time. At dusk, they all fly out at once, off to eat their dinner. Some bats around here eat mosquitos and other flying insects, while others eat fruit and nectar of cacti.

Bats make a great native animal to study.

Question: Which bat ears hear the best?

Procedure: Research bats, then make 3 different shaped bat ears (that fit behind kid ears) out of household materials, like paper plates. Alternately, make the same size and shaped ears, but out of 3 different materials, like construction paper, felt, and tin foil.

Blindfold one kid and have them hold on their bat ears. Using only hearing, measure how far away the listener can get from a ticking clock and still hear the ticking. Repeat 3 times with each type of ears.

Results: Figure out which of your bat ears could hear the best.

Judge’s comments: This was a great idea because the kids were studying bats at that time and thought of this original idea. They found out how sensitive bats ears are and recorded the information. They also made the bat ears themselves and took accurate measurements in metric units during the experiments. The students repeated their test many times to make sure the measurements were accurate. Excellent job!
