More science investigations-how long can we stretch an elastic band?

Our next investigation was to find out what happens when different masses are hung from an elastic band. We had a range of elastic bands and weights and the children had to devise a fair test to investigate their question. The variables they tested were: length of elastic band; width of elastic band and mass (g). The children measured the amount the elastic band stretched.The children collected some reliable results and were able to discuss their findings using their scientific understanding of forces.
