The hypothesis is that the cement (brick) will give the least interference and that the glass will have the most interference.

You will place a remote control car's receiver back wheels on the edge of a basketball court, have someone hold the remote control transmitter outside the door of the gymnasium, and then place different materials between the transmitter and receiver to see which one causes the most interference.

You will need a stopwatch, a 27 MHz remote control car, 24 AA alkaline batteries, 6 9v batteries, cement (brick), wood, and glass.

The results of the experiment were surprising. The wood offered the most interference, and then the glass and the brick offered the least interference to the radio waves. This was different than the hypothesis, which was that the cement (brick) would give the least interference and that the glass would have the most interference.

This science project is interesting because it helps us understand which materials can cause interference to remote control devices.

Experiment variations to consider include testing different materials, such as metal or plastic, and testing different frequencies of radio waves.

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!!
