PURPOSE (WHY?) To test how caffeine affects consumers by having them ingest energy drinks.Basically, we want to see ifthe energy drinks live up tothe expectations promised to the consumers.
BACKGROUND INFO Caffeine is one of the most popular drugs in the world. The average American ingests 4 gallons of energy drinks a year. Over eighty-five percent of Americans overuse doses of caffeine every day.
BACKGROUND INFO Caffeine can be both helpful and harmful to the human body, depending on how much is ingested.
BACKROUND INFORMATION Most energy drinks contain between 70 and 200 milligrams of caffeine. Common drinks, such as Monster Energy, RockStar Energy, and Red Bull, have around 160 milligrams.
QUESTION Do major energy drinks actually increase overall performance and, if so, which drink is the most effective?
HYPOTHESIS If the effects of Red Bull, Monster, and Rockstar energy drinks onthe performance of thirteen-year-old students are compared to students without the beverages, then…
HYPOTHESIS …students consuming the energy drinks, especially Red Bull, will have a significantly greater performance than students without the drinks, and students drinking Monster or Rockstar.

OBSERVATIONS- At the beginning of the testing, the test subjects seemed tired and unenthusiastic.- Students seemed more excited by having the drinks than by actually drinking them.
OBSERVATIONS -A few test subjects claimed to have been nauseous with bad vision after drinking their energy drink.-The student’s results for the second test were extremely close to one another.
