Transcript of Is your dominate hand more sensitive than your non-dominate

Is your dominate hand more sensitive than your non-dominate hand?

Hypothesis/Hypothèse:



We think that people will take their non-dominant hand out of the ice water first because your dominant hand gets used more than your non-dominant hand, so the dominant hand is a lot stronger than your non-dominant hand.Therefor, your non-dominant hand would be more sensitive.



Our hypothesis was that your non-dominate hand would be more sensitive, because your dominate hand is used more often than your non-dominate hand therefore , your dominate hand would be stronger, so it could handle the cold water.



•Left-handed and right-handed students


•A bowl that is big enough to put both hands in


•Ice water


•Stopwatch


•notebook for recording results

3.Record how long the student is able to keep each hand in the bowl of ice water.

5. Record whether the student is right-handed or left-handed.

6.Repeat steps 2-5 for many different right-handed and left handed students. Look over your results. Did right handed students tend to remove their right hand from water before there left hand? Did left handed students keep their right hand in the water longer than their left hand?









Materials/Matériels:



Experimental procedure/
procédure expérimentale:



1.fill the bowl with ice water


2.Tell one of the students that is helping you with your experiment to place both hands in the bowl. Instruct the students to keep his or her hand in the bowl as long as possible. ask the student to remove one or both hands when the discomfort becomes too much to bear. Both hands do not have to be removed at the same time.

3.start your stopwatch
