2 pendulums with different string lengths
The goal of the task is to determine whether the pendulum oscillation rate depends on the length of the pendulum string. Pupils consider the following predictions:
They accomplish a verification of predictions, record the results in a diagram and evaluate the research question by reference to the data obtained. When creating a diagram, the teacher helps them understand how numbers are transferred to the graphical display. Pupils color a part of the column according obtained data.
