This is a video aimed at pupils in KS3/4 that shows an experiment of a rubber band being stretched. The stretching happens when masses are added to the end of the band.
There is an introduction the experiment, which aims to help pupils understand the most important ideas.
After each mass is added the rubber band, the video zooms in on the scale to allow pupils to read this.
This can form the basis of a graphing activity to find the relationship between the masses added and the extension of the rubber band. Unlike the linear relationship of the spring, there are some differences in the way the band extends, particularly towards the start and end of the experiment.
There is a PowerPoint slideshow to help focus the activity if used in a classroom.
