• The aim of my project was to test the effects of caffeine on the heart rate of twenty college students

Project Overview

• Twenty University of Scranton college students- 10 males; 4 who drink caffeine, 4 who do not, and 2 controls- 10 females; 4 who drink caffeine, 4 who do not, & 2 controls

• A watch, notebook, and pen to keep track of results

What I Used For My Project

• I recorded the heart rate of students by checking their pulse at the wrist for 15 seconds, then multiplying the number by 4.

• Then I wrote the results in my notebook and converted the information onto a table.

How I Carried Out My Project

Test Males w/ Caffeine

Males w/o Caffeine

Control Group

Heart rate in beats per minute (BPM)

84 BPM 71 BPM 69

Heart rate in BPM

88 BPM 91 BPM ~~~~~

Test Females w/ Caffeine

Females w/o Caffeine

Control Group

Heart rate in beats per minute (BPM)

87 BPM 76 BPM 72 BPM

Heart rate in BPM

93 BPM 82 BPM ~~~~~

Results

• After carefully collecting and analyzing the data, I’ve concluded that caffeine consumption does increase heart rate.

• When dealing with students who regularly consume caffeine, more stress was placed on the hearts of the female subjects (table 2, column 2)

• When dealing with students who do not consume caffeine, more stress was placed on the hearts of male students (table 1, column 3)

Conclusion
