Exploring Skin Sensitivity

Problem: What parts of the body (forearm inside, leg calf, fingertips) are most and least sensitive to touch?

Research: 1) Please list 4 skin covered parts of the external human body that need to be most sensitive to touch to allow humans to survive.

2) Please list 4 skin covered parts of the external human body that do not need to be that sensitive to touch and would still allow human survival in our environment.

3) What are the advantages given to you by a skin covering that is sensitive to touch?

Hypothesis:

Procedure: Listen carefully to details given by your instructor on how to conduct this test.
