Newtonian Cooling Model  

Students perform an experiment with a simple temperature probe. They use their experimental results to determine a cooling constant, build a model and compare the outcome of the model with that of their experiment.

probe_temp(t) = probe_temp(t - dt) + (- rate_of_cooling) * dt
INIT probe_temp = 100
rate_of_cooling = cooling_constant*(probe_temp-room_temp)
cooling_constant = .03
room_temp = 22
