MY APPROVED TOPIC

I was told last week on Friday that the topic i have chosen, which is "Which energy drink will have increase your heart rate the most", since i have been told i have started to research energy drinks and it's effects, i started by googling it and then proceeded by clicking on the links that are closer up the page rather than the bottom. I have been on wikipedia and some other websites. The first priority for researching energy drinks was the health effects and the maximum amount i am able to consume within a time of 24 hours. Then i looked for the prices of the energy drinks. I plan to write up a hypothesis and an aim. The result will be shown as "GUARANA Vs. TAURINE" since all the energy drinks contain a pretty high dose of caffeine.
