::OBSERVATION::
Those drinking coffee appear to be more alert in class.
Does drinking coffee improve mental and physical function?

Can the effects of coffee alter coordination?

::HYPOTHESIS:: Caffeine improves your mental & physical reaction time to make you faster.

::EXPERIMENT/DATA::
Here we have a simple test of the speed of one’s responses. The purpose of the test is to determine what effect coffee has on a person’s reaction time.

This experiment was conducted by asking an equal number of participants, 5 who had drank coffee, and 5 who hadn’t, to catch a falling ruler when prompted by a buzzer.

Participants were asked to stand with their arms at their sides, fingers 1in apart.
As the buzzer sounded, the ruler was simultaneously dropped. Reaction times were recorded based on the time the ruler was caught.

::CONCLUSION::
After testing the reaction times of individuals who had or had not consumed coffee on that particular morning, we have concluded that there was no significant difference between reaction times. Coffee drinkers had both the fastest and the slowest time recorded at 0.175 sec and .400 sec. The non-coffee drinkers had similar results but stayed within the
