Question

investigate how the time for one oscillation of a simple pendulum depends on the height of the pendulum bob above the bench.

Answer 1

a Show a demonstration pendulum and ask students to think about the variables that may affect the time period for one oscillation.  

b Ask students to select one independent variable, collecting a set of data to investigate its effect on the oscillation time.  

 c After students have completed an initial investigation and drawn conclusions, ask them to evaluate their method in terms of its accuracy and improve on it.
