Caffeine and AlertnessFeatured science projectScience project video

Conclusion

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. 

Also consider

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.
