Cell Phone Radiation: Does it Heat Water?

Cell Phone Radiation: Does it Heat Water? | Science Fair Projects | STEM Projects
Do cell phones emit enough radiation to heat up water? Let's find out in this science project!

Hypothesis

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

Method & Materials

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.

Results

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.

Why do this project?

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

Also Consider

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).
