Rubberbands & Engineering
By Barb Stephens
You can try an experiment to learn more of the characteristics of rubber bands
and other elastic material. Get a collection of different sized rubber bands.
Measure them for length, width and thickness (if you can). Make a chart that
shows this information and mark each rubber band clearly so you know which is
which. (Using colored rubberbands is best.)
Rubberband | Original | Stretched | Length | Width | Thickness | Length | Width | Thickness |
With each rubber band, attach one end to a cup hook that is screwed into a
board. Attach the other end to a known weight. How far down does each rubber
band stretch? Does its thickness change? Does its width change? Which rubberband
is the strongest? Which rubberband is the weakest? How can you tell?
