DESCRIPTION
Hang a single spring and the series and parallel combinations from magnetic mounts stuck to the chalkboard or whiteboard.  Mark the unstretched lengths and the stretched lengths when supporting 100 g masses and compare the spring constants.  Or hang 100 g from the single spring and 50 and 200 g from the series and parallel arrangements (as shown above) to show that the extensions are the same.
