Bats are the only known flying mammal that as
it flies can emit sounds to locate his prey or
judge distance of a fixed object. His internal
sense of "hearing" allows him to receive a sound
picture back of where to locate the object or prey.
The students will simulate the sonar method
of echolocation that a bat uses by playing a game
with other students solely using sound** as a locator.
- **adaptation available for hearing impaired students
- OVERVIEW: Students will explore how bats use the sense of
echolocation in a game version of "Marco Polo" by
sending out sound signals to find the other players
simulating bats and insects accordingly.
- 5 minutes.
- 25 minutes.
WORDS TO KNOW:
- Locate large area for class to play the game in.
Similar to insects and birds, strong muscles provide
powerful wing strokes that aid flight. Unlike insects
and birds, many bats rely on echolocation to fly and hunt
for food. Echolocation works like the radar or sonar in
planes or ships. A bat hears the echoes and its brain
works out a sound picture of the object. It can tell if
the object is prey or part of the landscape.
While most humans are unable to hear the ultrasonic beeps of
bats, some children can. Some moths can hear the ultrasonic
pulses of bats and will change their flight path or drop to
the ground in order to evade capture. Others, like the Tiger
moth, will click back to resemble ultrasonic bat calls to confuse
bats into thinking they are another bat.
