Formal Purpose~

For our project we are researching the effects that different caffienated drinks have on your heart rate. For example, a cup of coffee may have a higher caffiene content than a can of soda, therefore giving you a higher heart rate.. But we don't know that for sure, so we're going to figure it out with this experiment. We will test the effects of caffiene by consuming different caffienated drinks for a week at a time and measuring our heart rate about 3 times a day throughout the whole week. The variables that we will be changing in this experiment are the types of caffienated beverages that we will be consuming each week. One variable that we aren't really able to control is different people's tolerance to caffiene. Some people may get really hyper and have a significant increase in heart rate when they drink caffiene, while it may not have much of an effect on others. In the first week of the experiment we will drink nothing but water, juice, etc. and be sure not to consume any caffienated drinks, the next week we will all drink coffee at the same time of day, the week after we will drink tea, and the final week we will drink soda. Each time we drink one of these beverages we will measure our heart rate right before drinking, right after, and finally about an hour after. When people see the results of this experiment they will be able to see just some of the effects that caffiene can have on your health, and may even influence them to drink less if they drink a lot of caffeinated drinks. From this experiment we can all learn what kind of effects something as simple and innocent as drinking a few sodas or coffees now and then can have on your health. (•⊙ω⊙•)
