The Case of the Cell Phone Car Remote

The Case of the Cell Phone Car Remote is a problem-solving scenario requiring students to work together to determine if a car door can be opened remotely by using a cell phone to transmit the key fob signal.
This lesson will probably result in students wanting to go to their cars and try the cell phone remote concept. If that is possible at your school, make arrangements prior to class so students have the opportunity, once they have done the prior problem solving, to visit the parking lot. This would be an excellent time to pair math and science classes because the standards in each dovetail nicely in this lesson.
