Caffeine and Alertness

Caffeine and Alertness | Science Fair Projects | STEM Projects
Do you want to know if caffeine can make you more alert? This experiment will have you drinking coffee and then testing your alertness by bursting balloons with darts.


The hypothesis is that coffee which contains caffeine will make the person more alert and energetic, resulting in the participant being able to burst more balloons.

Method & Materials

You will arrange balloons on a board, have participants burst them with darts from a distance, have them drink coffee, and then have them burst more balloons with darts.
You will need 480 balloons, 12 darts, a soft board, masking tape, 10 male and 10 female adults, and 20 cups of caffeinated coffee.


The results showed that the participants became more alert after drinking the caffeinated coffee, and were able to burst more balloons. This proved the hypothesis to be true.

Why do this project?

This science project is interesting because it tests the effects of caffeine on alertness in a fun and engaging way.

Also Consider

Experiment variations could include substituting the caffeinated coffee with a caffeinated soft drink, or testing the effects of caffeine on a different activity such as a computer game, throwing balls into a pail, or bowling.
