Obtain four plants, all of which are of the same size, type and grown in soil from one geographical location. Use three different energy drinks such as Red Bull, Gatorade and Rock Star and for your control plant, use tap water. Label the plants according to how you water them to note differences. Water the plants every morning accordingly and make note of any changes over three weeks.
If you're keen on undertaking a science project with energy drinks, consider the effect of the drink's sugars on the human body. Carry out a simple experiment by taking three types of energy drinks such as Red Bull, Amp and Gatorade, all of which have different sugar levels (as indicated on the cans). The timeline for this project is one week. Over this period, ingest these drinks separately, checking your blood sugar before and after. Conduct this test on more than one person to ascertain if the results are different or the same per energy drink and person.
Once you have completed the project, create a graph that shows the effects of energy drinks on different people's blood sugar levels. Make note of whether the energy drinks with the highest sugar levels show the maximum increase in blood sugar or vice versa.
Get creative with different ideas for science projects using energy drinks. One such idea might include choosing to test the specific effects of the different drink ingredients like caffeine or opt for a project that involves testing whether or not a person becomes "energized" after ingesting one. Another idea includes creating a science project using the electrolytes in an energy drink to power a light bulb. Compare which energy drink has the most "power." Instead, choose to test the effect of different energy drinks on tooth decay.
