This text and the experiments were created by sciences teacher of Genisea junior High School of Xanthi, Greece, Mrs. Lakka Irini.
The students experiment with the pendulum using different masses and measuring the period. Thus they are able to realize that the pendulum’s period does not depend on mass.
The students use different pendulum’ s length and measure its period.
They results help them to discover the relation between the length and the period of the pendulum.
At last they use different pendulum angles. They measure the period and they conclude that the pendulum’s period does not depend on the angle.
