Nerve Sensitivity Activity

 

Materials:

Three bowls;

* Very Warm water (DO NOT BURN YOUR TEST SUBJECT!)

* Ice water

* Room Temperature water

Towel

Test subject (a parent is good for this)

 

Procedure:

Place the bowls of water in front of the test subject.  Place your test subjects’ right hand in the warm water bowl, and the left hand in the ice water bowl.  Leave the test subjects’ hands in the bowls of water for at least three minutes. 

 

Have the test subjects move their hands from the separate bowls of water and have them place both hands into the bowl of room temperature water. 

 

Ask your test subject to describe what they experience in each hand.

 

Repeat procedure using yourself as the test subject.

 

Analysis:

Explain what you sense.  Be sure to describe your sensation in detail:

 

 

 

 

 

 

 

 

 

Be sure you answer the questions using full sentences. 

 

How does your hand that was in warm water feel in the room temperature water?

How does your hand that was in ice water feel in the room temperature water?

Compare and contrast how your two hands feel.

Describe how you are sensing heat and cold.

Why do you think that the nerves in your hands sense heat and cold the way that they do?

Why does one hand feel warm and one feel cold even though they are both in the same temperature water?
