Challenge question #1
Fri, 7 Mar 1997 11:45:12 -0500 (EST)
We are a homeschooling family of 11 (only 6 students at present) Two
students have graduated and 1 hasn't started yet. Three will be
participating in Journey North.
We think the answer to the sonar question is: Bats use sonar to find things
and find where they are. Their eyesight is very bad (nearly blind). They
use high pitched sounds that we cannot hear and it bounces off objects, so
then they know where those things are. Bats have very good ears so they can
hear the highpitched sound but we can't. Another form of sonar is radar.
We are very excited to join this discussion and follow the bats this
