How do I make a science project based on this hypothesis/question/materials?

This is for my science project eighth grade. the question is "Caffeine affects your heart rate? My assumption is yes, and it makes my stethescope materials, coke, coffee, decaf, diet coke without caffeine and water and tea (black, green, herbal) ideas for how to turn this project? Suggested materials are also welcome. thanks!

Not a very safe. Caffeine affects the heart, it? been demonstrated in numerous scientific studies. Too can damage your heart. How about a pi? safe and subject in some way and if not crude. How much should one eat asparagus to change the color in your urine
The scientific method the result was 4 basis points. Observation, hypothesis, experiment and conclusion. Sounds like you have a good case, so as to work to set up your experiment. Use water as your negative control (while knowing that no caffiene) and then try other products accordingly. A p? t?, even those herbs contain caffeine, so be sure to take note of that when it's the real experiment. Use the stethoscope to count the heart beats per minute to say, 30 seconds after 1 minutes of consumption of each of the different drinks, or just use your imagination to provide another set of circumstances. Good luck on your project!
