Reaction Time Experiment

This is an video to tell you how to test the speed of your nerves, or reaction.

You need to find a worthy partner, two rubber bands and two 30cm rulers. Then you figure out who is testing, and who is being tested. Watch the video to see how to do the procedure. Our hypothesis was that the dominant hand would be faster than the non-dominant hand.

The independent variable is how long it takes to catch the ruler. The dependent variable  is the difference between the reaction of the dominant and non-dominant hand. And the controlled variables are where the ruler drops from, position of arms,  position of fingers etc.

Steps:

1.Get a friend or a family member to do this experiment with you.

2.Put a rubber band around you index finger and

your thumb make sure that you don't put too much pressure on the rubber band you should just put enough that the rubber band won't stretch too much just a little.

3. Get your partner to line up the ruler with your index finger you should align the 0 centimetre point with your index finger.

4. Your partner will drop the ruler unexpectedly then you have to catch the ruler before it falls down on the floor. Lets say you got a hold of the ruler at 6cm then you have to record it on to a graph.

	Left Hand	Right Hand
1	31cm	31cm
2	31cm	31cm
3	31cm	31cm
4	31cm	31cm
5	31cm	31cm
6	31cm	31cm
7	31cm	31cm
