Are You Left or Right Sided?
Question: Will people use one side of their body more than the other?

QUESTION: Will people use there right side of their body more than their left?
HYPOTHESIS: People will use their right side more than their left?
MATERIALS LIST:
0. A ball
0. A paper towel tube
0. A phone
0. Pen and paper
PROCEDURES:
Step 1: Find volunteers to do take the test.
Step 2: Once you find enough volunteers have them go through a series of test to see what part of there body is in more use.
Step 3: First you see what foot they use to kick the ball and record your data.
Step 4: Second you give them a paper towel tube and see what eye they put it up to, then record your data
Step 5: Third give them a phone and see what ear they put it up to and record your data.
Step 6: Lastly give them a pen and paper and see what hand they use to write on the paper with then record your data.
Step 7: Repeat steps three through four, for all your volunteers.

Results: The data tables shows that the biggest difference was between the right and left handed girls. The table showed that the right hand is the most dominate between men and woman. In women there was a far more difference but with the other categories it was very close. If you look at the data table you can see that men had the closes dominate in right and left hand, but you can also see that in men that there wasn’t that much of a difference. So according to our data the right part of men and women were used the most but you can also see in men that the total was right near each other.
Conclusion: Our hypothesis was correct. We stated that people will use there right side more than there left. The reason why we say this is because the majority of the people our partners and we tested were right handed and used the right side of there body more than there left. We got some information off the computer to back up some of our opinions. One website talked the handedness between rights and left, it said that handedness can be described as a hand that performs faster on manual test, according to our data that is the right hand. However I’ve found some information on the right and left hemisphere of our brain. Some people may not know that are brain is split into two such like and apple cut in half, one side of the brain is the left and another is the left. The information that we found tells me the side of the brain is specific for speech production and language comprehension. The right hemisphere comes into play when people can’t understand a certain language. Therefore our data proved that the right part of the body is used the most.
