BSTRACTFor the experiment, I researched what side of the hemisphere people use the most. My hypothesis was more people would use their left mind more because the majority of humans are right-handed. I wanted to see how the participants would have the same patterns or different patterns if they would switch sides of their body. My method of testing my hypothesis was doing simple tests on the test participants. The results came together after the experiment. It seems more people are right-handed than left or even both. The conclusion explains everything that happened during the
experiment and etc. It tells how the experiment went, telling the hypothesis, what came out of the results, and telling the background research.
Q UESTIONS & H YPOTHESIS
More people would use their left mind more because the majority of humans are right-handed.
S ome people use their creativity either when they are drawing, painting, or expressing themselves with a poem. Or just using their imagination. The right hemisphere controls the left side of your body which is the arts.
On the other side, which is the left hemisphere, controls the right side of your body meaning to do logic, science, or math. If I predict they will use the right
hemisphere the most.
B ACKGROUND R ESEARCH
The brain (-Brain, Not brian) has two halves because it can perform different functions (Agata 1). This is because the right hemisphere is more creative while the left hemisphere is more logical and analytical (Agata 1). It can also see different points of view. The left brain is believed to be used the most. Although true, the right and left brain usually work together to perform tasks. It takes these two minds to be logical and creative (Taina 1). An example of how the two hemispheres work together is like a rubix cube. It is fun but confusing. Knowledge is the transition with two sides to it, the mind which knows and the objects known (Harcourt 136). The brainstem, which is the middle of the brain, includes the midbrain, the pons, and the medulla. There are two
hemispheres that make up the brain. The right and left hemispheres work together to control each side of the body. The left half takes over the right and the right half takes over the left. They both help the body communicate with each other. The mind has a number of different possibilities. The mind stores information and memories in the long
term of time, which is why it is easy to recall information or memories. Recalling
information is a great way to exercise the mind in order to retain important information. The mind acts like a sticky note, where it retains information as to how an object looks like. Additionally, the brain retains good and bad memories (Caroline 1). It is also where imagination and creativity take place (Caroline 1). The right mind is generally used in unique or creative situations (Tania 1). Furthermore, the right mind is also used in situations to think outside the box, be artsy, or to assist the left brain .
The right mind can also take place as emotions and expressions. Nobel prize winner, Roger W. Sperry says that the right brain connects to; imagination, holistic thinking, intuition, arts, and rhythm. Even nonverbal cues, feelings, visualization, and daydreaming. This is how the right mind functions (Ann 1). The left mind takes place when doing homework, working, or solving problems. When drawing an illusion of chalk on a sidewalk or some type of graffiti, is also using the left and right hemispheres. It takes math and models to create the illusion to trick or change people's perspectives.
The right mind can carry defined activities (Scientific American 27). The right mind can carry defined activities. It is said that a person from Croton, who first considered the brain to be the place where the mind was located. That is where we think and create different things at once. The left mind is the advantage for math and reciting multiplication tables. And the right mind is the advantage of some small amount of math-related tasks, especially estimating the quantity of a set of objects (Tania 1). The left hemisphere is mostly responsible for language and speech ( Agata 1). That can also help us when we are public speaking or making a speech with someone
important or famous. Language helps us to communicate with other people. It is a good way to study this and that is where the brain saves this information. The cerebral cortex is the thin layer of the brain that covers the outer section of the cerebrum. It is covered by the meninges and often referred to as gray matter. The corpus callosum is a large, C-shaped nerve fiber pile found under the cerebral cortex. It stretches across the
midline of the brain, connecting the left and right cerebral hemispheres. And it can make up the largest collection of white matter tissue to appear in the brain.

Variables
● Independent:
○ Placement of material ● Dependent:
○ How your mind responds to your actions ● Controlled:
○ The activities
D ATA C OLLECTION
For the experiment, there were ten people who were tested on these courses. The recording was to see how the participants reacted with tasks given and see which hand or foot used in this experiment and to identify if they used their left or right
hemisphere. We recorded this three times to see if the reaction changed or stayed the same. This helped to see which people used their left or right side of their minds. There were five courses for each of the ten participants. Recorded it three times to see if anything changed.

A NALYSIS
To perform this experiment ten participants were experimented on to see if they used their right or left hemisphere. The first graph is explaining how many of the participants used their left or right side of their body to kick the ball. This will let us know if they are using their logic or the creative side of both hemispheres. If the results come out as R, R, L, or something like that then that is most likely to be that the participants are using both of their minds to work together. In the second graph, it is explained that the participants used their right side of the body more than the left side. We can see the people who are right-handed use their left mind (logic and language) to pick up and brush their hair. The third graph, it is showing the ten participants who used their right or left leg to step on the stairs. Don’t count the ones that they stepped down on only the first step. This will show which pattern they used to step up on the stairs. As we can see the participants mostly used R, L, L which means right, left, left foot. This means that they are using both of their minds to work together to solve this course. The fourth graph is showing the “Pouring Water” course. This lets us see which hand they used to pour the water into the cup. And most of the participants did their right hand. The last and final graph shows the “Open a Door” course. This part is where you let the
participant know to just open the door. And half of the participants opened the door with their right hand and a little more of the people used their left hand. After they opened the door three times the experiment was finished.
While trying to put the results together we can see out of all the participants used their right side which meant that they used more of their left hemisphere, which is their
logic and language, the most out of their right hemisphere, which is the creative side. There was no effect on the experiment rather than keeping the results of the ten participants.
C ONCLUSION
My hypothesis was which side do people use the most? The hypothesis meant to see who was more right or left handed, but as we can see there was more right handed than left handed. When the results came together it was a surprise that both right and left hemispheres were on the charts, so it means that their brains work together to help the body get past the experiment. For the background it is explaining how the left and right hemisphere work together to accomplish anything ect.The brain (-Brain, Not brian) has two halves because it can perform different functions (Agata 1). This is because the right hemisphere is more creative while the left hemisphere is more logical and
analytical (Agata 1).
Throughout the experiment it was tested on the ten participants if their left or right handed occurred to their hemisphere. most of the participants were right handed so that meant their right side of their body was controlled by the left hemisphere. The left
handed people were controlled by their right hemisphere which meant they were creative and the right handed people were all about logic and language. The data
collection was to check if they used their left or right hemisphere due to the experiment. It helped us understand how they had reacted to the experiment to give us the
information needed. It was noticed right away that more people are right handed which is controlled by the left hemisphere. But there was a twist. It also had seemed that not less than left handed people but both right and left handed were used in the experiment.
The analysis was explaining the charts and graphs gathered to see how the experiment went. Again, more people were right handed than left handed.
B IBLICAL P RINCIPLE Romans 12:2
“Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.” I chose this bible verse because no matter what side of the hemisphere
controls our body God says it's perfect. This also relates to the experiment. Our mind controls what side of the body it wants. We were testing to see what side of the hemisphere they were using.
S TUDENT L EARNING E XPECTATIONS
A2: Are skilled problem solvers that utilize critical and creative thinking skills. I choose this SLE because it also relates to this experiment. We use creative thinking skills when both of our hemispheres work together to get out of a problem. This tells how we can solve things in a creative way. It helps us see it differently than other people.
