This experiment was conducted to find out how drinking caffeinated coffee will affect the alertness of an individual. The level of alertness of the test subjects will be measured by the number of balloons burst by throwing darts.
Coffee which contains caffeine will make the person more alert and energetic. This will result in the participant being able to burst more balloons.
What is caffeine?
Caffeine is normally found in coffee and tea. It helps to keep us alert and also prevents us from falling asleep. Caffeine is able to help us stay alert and awake by:
Caffeine, caffeinated, adrenaline, dopamine
The materials required for the experiment:
You should observe that the participants would become more alert after drinking the caffeinated coffee. They should therefore be able to burst more balloons after drinking the coffee as compared to before they have drunk the coffee.
Use this table below to help record your observations.
The male participants had improved their results by 23.6% after drinking the caffeinated coffee. The female participants had also improved their results by 20.8% after drinking the same caffeinated coffee.
The hypothesis is proven to be true. The caffeinated coffee has helped to improve the alertness and energy level of the participants. This has enabled them to improve their aiming and burst more balloons.
Caffeine is found not only in coffee and tea, but also in soft drinks such as Coke. Shift workers and long distance driver depend on such drinks to keep them awake.
What would happen if the experiment was conducted by substituting the caffeinated coffee with a caffeinated soft drink?
Try some other activity, like a computer game, throwing balls into a pail or bowling to measure the effects of caffeine.
