Transcript of Twirls, Whirls, Spins, and Turns. The Science and Reflexes of Dizziness by: Rebecca Benson

Does covering your eyes and plugging your ears help prevent dizziness while spinning? The Science and Reflexes of
Dizziness Twirls, Whirls, Spins, and Turns By: Rebecca Benson
7th Grade
Mr. Roberts
I chose this topic because I had been getting very dizzy often and I wanted to figure out what was causing it. I was going to do that on my own time but I found a way to research it now. Purpose The purpose of this experiment is to find out what simple techniques you can use to make you less dizzy while spinning. I am able to measure how dizzy a person is just by looking at their eyes. I use spin tests to see how important our eyes and ears are in balance and dizziness. It will help other scientists and my community learn more about the causes, consequences, and preventions of dizziness Hypothesis My hypothesis is that if by covering your eyes, plugging you ears, etc. then you can make yourself less dizzy while you spin. Experimental Design The constants are the chair and the environment. They do not get changed. (There are 4 volunteers). The one who is getting spun will do 3 tests. All of these tests will be done 3 times to make sure they are accurate. The volunteers will be the manipulative variable. The tests are the independent variable because they are changed. Materials -Four people
-An office chair that spins smoothly and doesn't tilt back when spinning
-A room with plenty of clearance to spin the chair
-Stop watch or a video camera with a time stamp that shows seconds
-A tripod, if you use a video camera
-Soft ear plugs for each volunteer
-Notebook or paper
-Pen or pencil Procedure 1.) Decide who will be spun in the chair first. One other person should be designated as the "observer." The observer will be in charge of the stop watch or video camera, if you are using one. Two other people will act as the "spinners" of the chair. These roles can be switched as each person takes their turn being spun in the chair.

2.) Make sure no furniture or obstacles are near or around the chair.

3.) For each test, have the volunteer sit down in the chair, insert the ear plugs, put their hands in their laps, and close their eyes. They should keep their eyes closed during each test and not open them until the observer says so. Ear plugs should also be worn during the test unless the volunteer is told to take them off.

4.) Ask the volunteer to make two fists with their thumbs straight up and keep their hands in this position on their thighs during each test. Using their thumbs, they should indicate the direction they feel they are moving while they are spinning with their eyes closed. Immediately after they stop spinning, while their eyes remain closed the volunteer should use their thumbs to again indicate if they feel they are moving to the right, left, or not at all (thumbs straight up).

5.) At the end of each spin test, ask the volunteer to remain seated, open their eyes, and look directly into the camera or at the designated observer.

6.) The observer should note or film any eye movements, time how long they last, and record which direction the eyes are moving, if they are moving at all.

7.) Each spin test should be done three times by each volunteer.

If a volunteer feels very dizzy after a test, let him/her sit in a non-moving chair for a few minutes before trying the next test. If a volunteer begins to feel sick at any time, he/she should stop all tests. As a result of my experiment I figured out my hypothesis was right. I figured out by having your ears plugged, being blindfolded, and having a gradual stop people were less dizzy. On test #1 the average dizziness rating was 3.75. On test #2 the average dizziness rating was 3.66. On test #3 the average dizziness rating was 4.33. This relates to my purpose because I learned that by stopping the spinning object gradually it will make them less dizzy. Results My major result is that by having a gradual stop with earplugs and closed eyes you wont be as dizzy.
Yes it did
It proved that the information I read was correct. I could explain that by having your eyes uncovered they move more because they are trying to look at what they see.
Yes there was actually, but we fixed it. My little brother was not answering the questions he was asked accurately because he was tired and bored.
I would of done it earlier so we weren’t as tired.
I could study about what exactly the eye movement is called. Conclusions Source 1- http://www.healthyhearing.com/content/articles/Research/Dizziness/7734-Dizziness-a-common-problem
