Simple Pendulum    

Students will test two variables, to determine their effect on the pendulum’s period. Just as objects with different masses accelerate in free-fall at the same rate, changing the mass of a simple pendulum will not change its period. Changing the length of the pendulum does effect the period, with shorter pendulums having shorter periods.
