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
9 tbsp Caffeinated coffee
9 tbsp Decaffeinated coffee
20 mL milk per cup (Total- 360 mL milk)
20 mL water per cup ( (Total- 360 mL water)
Electrical Kettle
Timer
Paper and Pencil

  • Daphnia Heart Rate

    My group recorded higher heart rate compare to the class average when we used caffeine on the Daphnia as seen in Figure 2. Several errors could have accounted for this data. This including perhaps the Daphnia’s heart rate may have changed because of fear while being moved from the bowl to the microscope slide. Another possible error could have also been the amount of time that it took to change the solutions, which could have accounted for slight variations in heart rate. Temperature is yet a further error to account for as the microscope slide temperature was constantly changing to view the specimen, and change the dosage of caffeine or alcohol.

When the hormone is active it forces the liver to provide the bloodstream with additional
