 * __Materials&Methods__**

For our expirement we gathered the following materials: Folgers classic mild roast coffee, a coffee maker, 9oz plastic cups, stopwatches, and a table spoon. We used our spoon to add four tablespoonfuls of coffee to our coffee maker. This made two 9oz cups of coffee. We filled two cups with the coffee and made sure they were full. Next we went to our test subjects with the coffee. Before the person drank the coffee we measured his/her heart rate for 30 seconds and asked the person their caffeine intake for that day. We recorded this data to know the total intake of caffeine that may have an effect other than the coffee. Next the person drank his/her coffee. It took longer for some to drink because it is hot. After a 5-minute resting period, we checked his/her heart rate again. Note that we checked the wrist or neck to determine the heart rate. Then recorded the data.

Independent Variable: The presence of coffee.
