Blinking

 * Topic-** Video...Computer...Games...Student...Blink...Faster
 * Question -** Do **video games/computer games** make the average **student** **blink** **faster** after they are done playing?

[|What they are for ?] [|Per Second... Per Minue]
 * Background info and Sources-**
 * A.** When we blink, sebaceous glands and tear glands lubricants our eyes to prevent them from drying out. Each time we close our eyelids, salty secretions from the tear glands sweep over the surface of the eye, flushing away small dust particles. Our eyelashes serve as dust catchers.
 * B.** A blink lasts about a 10th of a second, and almost all people blink at least 20 times a minute, or every 4 seconds.


 * Hypothesis -** My hypothesis is that the average student will blink faster after they are playing a video game because according to my research while they are staring at the screen for short periods of time between blinking dust particles will fly into the eye. Their for causing them to blink more in order to clean and remove all those particles.

Computers/video game system at least 8 students (4 boys, 4 girls) two recording charts stop watch or clock virtual games
 * Materials -** I will need...


 * Procedure -**
 * 1)** First make two recording charts.
 * 2)** Now take one of the recording charts and label it Average Blinking Chart. This is the chart that you will write down the recordings of peoples average blinks. (Recording chart 1 should look something like this... [[file:Average Blinking Chart .doc]].)
 * 3)** Use your second chart to write down the recordings of the blinks after they've played the virtual game. Label this chart "Blinks After Virtual game." (Recording chart 2 should look something like this... [[file:Blinks After virtual game recording chart.doc]].)
 * 4)** Once you've finished making both of your recording charts, you should choose at least 8 to 10 people to use for your experiment.
 * 5)** Take one of the people who have chosen an ask them to just sit and do nothing for a minute.
 * 6)** While the person is sitting their you will count how many times they're blinking. (With out them knowing)
 * 7)** Once the one minute is up record the data you received onto your Average Blinking Chart.
 * 8)** After they have sat there you will have them play a computer game for a minute.
 * 9)** After they play the computer game you will have them sit and do nothing again. An once again while they are sitting their you are to count how many times they blink.
 * 10)** Record they data you receive on step 9 and record it on your Blinks after Virtual game chart.
 * 11)** Do steps 5 through 10 to all the people you chose and make sure to record your data.
 * 12)** After you've finished your experiment, write down your conclusion and decide if you hypothesis is correct or incorrect.


 * Experiment-** Do the experiment.

.
 * Data/Results-** Here is the data and the results from my experiment, [[file:Average Blinking Chart .doc]] and

If I were to do this experiment again I would change couple of things. First of all instead of doing one person at a time I would do two people at a time by having one of them count the other ones blinks than switch off. I would do this because well I will get more data faster and I would feel more comfortable. I would also change my question to, do **video games/computer games** make the average **student** **blink** **faster** while they are playing them?
 * Conclusion-** In conclusion I found out that my hypothesis was correct. I also found out that when you tell a person why they are doing what they are doing they attend to do it more. For example when I told a student that I would be counting how many times they blinked after they played a game they blinked more often because they were thinking about it. Girls also blink more according to my data/results.
