The hypothesis is that cell phone radiation does not contain enough energy to increase the temperature of water in a test tube.

You will test three different cell phones from three different manufacturers, measure the temperature of the water before and after the cell phone is left ringing for two minutes, and record the results.

You will need an Ericsson cell phone, a Nokia cell phone, a Motorola cell phone, three test tubes, 30 ml of water, a measurement cylinder, three thermometers, and a stopwatch.

The experiment showed that the temperature of the water in the test tubes did not increase after the cell phone from the three manufacturers was left ringing for two minutes. This proves that the hypothesis is correct and that cell phone radiation does not contain enough energy to increase the temperature of water in a test tube.

This science project is interesting because it tests a common belief about cell phone radiation and provides evidence to support or refute it.

Variations of this experiment include testing other cell phone models and brands, and testing to determine if the temperature increases during cell phone conversations (as opposed to simply ringing).

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
