Pendulums – collecting and using data
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.
Pendulums and data collection
Use simple equipment to collect data, plot the data on a graph and use the graph to make predictions.
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.
