Transcript of Is your non dominant hand or dominant hand more sensitive to

Is your non dominant hand or dominant hand more sensitive to the cold?
Materials!
-Two left handed people from 8th grade class
-Two right handed people from 8th grade class
-Large bag of ice(large enough to place both hands in)
-Stopwatch
-Notebook paper and pencil to record results
Steps
-Step 1-Get a large bag of ice
-Step 2-Ask someone who is right or left handed to begin(at least 2 per dominant hand)
-Step 3-Put both of their hands in the same bag of ice
-Step 4-Start the stopwatch and record how long they keep their last hand in (either right or left)
-Step 5-Make sure you record which hand is taken out first
-Step 6-Repeat steps 2-5 three times
Time And Number Of Trials
This project took six days including the time spent on the lad report and visual representation. It took two days in class to actually test the experiment. Then once that was finished, it took 3 days for the lab report with some technical difficulties. Finally this visual representation took one day to finalize and check all of my work.
First right handed person:
This right handed person took their right hand out last at a time of 16 minutes and 3 seconds.
Second right handed person:
This right handed person took their right hand out last at a time of 6 minutes and 21 seconds.

Right handed Results!
As you can now see a person who's dominant hand is the right hand their left hand is most likely more sensitive
First left handed person:
The first left handed person took their left hand out last at a time of 3 minutes and 46 seconds.
Second left handed person:
The second left handed person took their left hand out last at a time of 2 minutes exact.
Left handed results!
Now you can see that a person who's dominant hand is a left hand, their right hand is more sensitive to the cold.
Hypothesis
If both hands are in ice then your non dominant hand should come out first, because it is most likely more sensitive.
Variables
Independent variable: Dominant hand (two people for each dominant hand)

Dependent variable: Sensitivity (which hand is more sensitive to the cold)
The number of trials I made for both hands would be two so in all I had four trials. this means two left handed people and two right handed people.
Constants and Control
I had many different constants for example:
-Same size bag of ice
-Same stopwatch
-Same recorder and timer
-Same place
The control would have to be people because nothing changed except the person who had their hands in ice.
Quantitative or Qualitative?
This experiment could be both quantitative and qualitative because it is possible to tell which hand lasted longer, but it is not an exact measurement of sensitivity.
