### My Science Fair Experiment

1. 1. My science fair experiment By: Hannah Hoskins
2. 2. Hypothesis and Purpose <ul><li>My hypothesis is; </li></ul><ul><li>If the color yellow is seen first then it does affect how quickly a person can see an object in the dark. </li></ul><ul><li>My Purpose; </li></ul><ul><li>Is to find out what colors you can see in the dark the fastest. </li></ul>
3. 3. Things you will need <ul><li>3 pieces of paper (example yellow, purple, black) </li></ul><ul><li>Tape (to hang the pieces of paper up if you want to or u could hold them up.) </li></ul><ul><li>Stopwatch </li></ul><ul><li>At least 10 people to test this on </li></ul><ul><li>A dark room </li></ul>
4. 4. Variables <ul><li>The independent variable is the color of paper. </li></ul><ul><li>The dependent is the time it took to see the paper. </li></ul><ul><li>And the control variable is same room, same paper, and same stopwatch. </li></ul>
5. 5. Procedure <ul><li>First find a dark room </li></ul><ul><li>Next get three colors of paper. One bright like yellow, orange ,or red, another a middle color like blue green or purple, and the last could be brown or black. </li></ul><ul><li>Next hang one of the pieces of paper on a wall in the dark room. </li></ul><ul><li>Next select at least 10 people to take this test. </li></ul><ul><li>Bring the first one into the room while covering there eyes and stand them in front of the wall with the color on it. </li></ul><ul><li>Instruct the test subject to announce when they see the color on the wall and record how long it takes them to see it. </li></ul><ul><li>Remember to write down the color and the time it took for all three colors. </li></ul><ul><li>Repeat step 5,6 and 7 </li></ul>

7. 7. My Graph
8. 8. My conclusion <ul><li>The conclusion is that the hypothesis was wrong. The purple paper was seen the fastest because the retina saw the color purple and told the brain the fastest. The hypotheses predicted that since yellow was the brightest so it would be seen the quickest. The research could have come out different if a had a darker room or a bigger pieces of paper and if a had a blindfold on longer. </li></ul>
