Background Information

The websites on the bottom are where I got my information from and to learn that from the beginning that the dominant hand was going to be more sensitive than the non- dominant hand.

ypothesis

I predict that the dominant hand is going to be the least sensitive because you mainly do everything with it and it being cold is just something that wouldn’t phrase it that much. The non- dominant hand

i

would say would be the most sensitive because you rarely do anything to it so it actually feeling and doing something it is going to react differently to the cold water causing it to be more sensitive to the ice water than the dominant hand.Slide5
