We will be using a PhET Simulation.  It is set up so that the student can vary a number of parameters for a spring-mass system.  These parameters are mass attached to the spring, the spring constant, the frequency of a driver that the spring is attached to, the amplitude of the driver, and the damping factor for the system.  This can be considered air friction, and will cause energy to dissipate from the system.  One other feature is to have multiple springs attached to the driver, so direct compare-contrast can be done.

You will need to run controlled experiments.  This means keeping all values of parameters constant, while choosing only one parameter to vary.  This allows you to see the effect of that one parameter on the vibrations of the system. You can measure periods with a stop watch, and there is a ruler option built in the simulation.

Note to student: You are not expected to know much about resonance.  The challenge for you is to act like a real scientist and, purely from your observations and measurements with the computer experiment, determine the cause and effect of each parameter on the vibration of the spring, and try to find conditions where the system goes into resonance with the driver.
