1) Describe what you know about whiskers.
2) Have you ever seen an animal use its whiskers? Explain.

3) How do scientists know Etruscan shrew uses its whiskers to find crickets? Explain which whiskers the shrews use to find the best place to bite a cricket.
4) If you trimmed the macrovibrissae and microvibrissae on an Etruscan shrew, and then released it in the wild, what might happen to it?
5) Why do you think scientists placed a blindfold and earmuffs on Henry while running the motorized paddle?
6) Was Henry the seal better at telling apart two paddles of different sizes when the paddles moved: a) at the same speed? b) at different speeds?

2) First, brainstorm a list of animals that have whiskers. Next, list several ways each animal uses its whiskers to either find its way or locate food.
1) Blind people may not have sensitive whiskers but still use their sense of touch to help find their way. Do you think we could make homes, schools and offices more touch-friendly? What additional information about these settings could we make available to blind people through their sense of touch?
