Impact of Age on Reaction Time in Individuals
The effect of age on reaction time is explored through a simple experiment using rulers. Different age groups - adults, seniors, and children - are compared to determine how quickly they react to stimuli. The procedure involves catching a falling ruler to measure reaction time. Results are analyzed to understand if older individuals have slower reaction times.

How does age affect reaction time? Adult Child Senior Adult
How quickly or slowly you react to something is called your reaction time. Your Reaction time is measured by how long it takes for your eyes to tell your brain that the ruler is falling and then for your brain to tell your fingers to catch it. The ruler falling is the stimulus and this type of reaction is a simple reaction. The simple reaction time is the time it takes to react to a simple stimuli- or a small change in your environment.
To find out if age affects reaction time. I want to discover this to see if I need to give my grandparents and parents extra points when playing wii tennis.
I think that the senior and the adult reaction time will be slower than the child s reaction time.

1. Sit in a chair with your arm resting on a table so that your wrist hangs off the edge. 2. Have a friend hold the ruler so that it dangles above your hand. 3. Make sure the end of the ruler is hanging between your thumb and finger. 4. When your friend lets go of the ruler, try to catch it between your thumb and finger as quickly as you can. 5. Compare the marking on the ruler where your fingers caught it to the reaction time chart. 6. Make a mark on your graph next to the matching reaction time over the Trial 1 column.

Thank-you Mom for helping me type up my report and making my board. Thank-you to my teacher for helping me measure my results and make my graph using excel. Thank- you to my grandma, mom and my friend who dropped the ruler for me.
Does my Reaction Time improve with practice? Is the reaction time different with my right hand compared to my left hand? Does my reaction time increase with fast music being played? Are boys reaction times faster than girls?
