Purpose
In the real world, many millennials and adults are encouraged into drinking coffee because they believe that it increases their energy and helps to concentrate better. We have decided to investigate the placebo effect and see how the type of caffeine affects one’s concentration and heart rate.
Safety Hazards
Don't leave the kettle unattended
Do not give a dangerous amount of caffeine to the participants.
Make sure you wear the proper attire for the experiment.

Dependant Variable: Heart rate and Concentration.
Control Group: All the participants did the concentration test before being exposed to coffee in order to be able to compare the outcomes without the independant variable with the results with the independent variable.
Control Variables: Same participants, same gender, same amount of water, same age group, same time wait.
Hypothesis
In this investigation, I want to find out whether the type of caffeine has an effect on the human body’s heart rate and concentration. After conscientiously researching the placebo effect and the effect caffeine has on the human body, I presume that If the participants drink both caffeinated or decaffeinated coffee the results of their heart rate and concentration will be higher than the results before drinking coffee. To be specific I do estimate that the heart rate and concentration will be affected remarkably by the caffeinated coffee more that the decaffeinated coffee. Materials
