Research Question

How will caffeine, guaranine, and ginsenosides affect the central and peripheral nervous system (Reaction time, blood pressure, and pupil dilation)?

Support from Mrs. Churchill/McDonald

This lab can be done at home, but a few questions may come up. If my group has any questions, we will ask.

Expected Time Line

EXPECTED TIME LINE

How long will it take to set up and design your lab?

-The lab has been designed. The subject will take 200 mg of the stimulant and it's effects will be measured after 10 minutes of the dose in this order: Reaction time, blood pressure, pupil dilation.

How long will it take to collect your data?

-It may take up to 2 weeks to collect the data.

How long will it take to analyze your data?

-It will not take any longer that one week to analyze data.

How long will it take to report your data/finish publishing your lab on your web page?

-The lab should be finished early May.

Methods (2)

Reaction Time: A yardstick will be dropped vertically near the subject's open hand. This will be done 3 times, and the number the subject's index finger touches will be recorded. The average will be found.

Blood Pressure: A blood pressure measuring device will be used.

Pupil Dilation: The subject will have his/her eyes exposed to a flashlight. Then, the subject will be put in a dark room for 2 minutes. A picture will be taken of the subject's eye.
