  • In this investigation, students measure the period of pendulums of varying lengths, plot the data on a graph and use the graph to estimate the period of two new pendulums – one with a length between two of their collected data points and one from a much longer pendulum.

    By the end of this activity, students should be able to:

    • collect and interpret data
    • construct a graph from collected data
    • use a graph to interpolate between two data points
    • use a graph to extrapolate a value beyond measured data points.

    This investigation is related to Investigating pendulums – what matters?, which investigates the variables in a pendulum system and uses similar equipment.
