Task 6

Materials and tools for a working group:

Pendulum

The aim of the task is to find out whether the pendulum oscillation speed depends on the height from which the pendulum bob is triggered. Pupils consider the following predictions:

• I think, the swing of pendulum will be faster if I trigger it from higher height.
• I think, the swing of pendulum will be faster if I trigger it from smaller height.
• I think both pendulums will swing the same rate.

They verify proposed predictions, record the results in a diagram and evaluate the research question by reference to the data obtained from the measurements. They find that the oscillation rate of the pendulum does not depend on the height from which the weights start.
