Conclusion

Trial 1

Our conclusion for our experiment was that, the age group, 8-20 had the quickest reaction time. We made some errors while conducting the experiment, but none that made a major impact on the results. Overall, it was very successful and very fun to conduct.

Materials

Paper note cards, timer, camera, pencil, & table to place note cards

Repeated Trials

Test everyone in each age group twice

Questions Asked

2+2=?

What country do you live in?

Blue+Red=?

How do you spell Mississippi?

What is your favorite color?

Procedures

1. Find four people to test for each age group.

2. Ask them a series of questions, while timing them

3. Collect data and sort it by age group

4. Find the average time for each age group

5. Repeat steps 1-4 again to make sure the data you collected is accurate (repeated trials)

6. Record both sets of data on a chart and compare the two trials

7. Order the age groups based on the quickest time (first being the fastest and last being the slowest)

Hypothesis

If the human's age is between 21 & 33, then their reaction time will be quickest.

The Effect of Human Age on Reaction Time

IV, DV, and Constants

IV: Human's age (4 levels of age groups)

DV: Reaction time

Constants: time measurement (sec), amount of questions (five), and amount of possible answers (four)

Introduction

Our science question we are investigating is about the human reaction time. We are interested in this experiment because we were wondering why certain people have a faster reaction time then others. Though we didn't find much information about this experiment due to the fact that not many people have attempted this experiment, we did learn that people in their mid 20's tend to have the quickest reaction time.
