Rubber Band Stretch Experiment

Repeating the experiment a total of three times will help you determine if your findings are consistent and reliable.

Rubber band stretch experiment.

Shoot more rubber bands in the same way except stretch them back to 15 cm 20 cm 25 cm or 30 cm. In this experiment you will find out how the stretching of a rubber band affects the amount of energy that springs out of it. Objective investigate how the distance of stretch in a rubber band at rest relates to the distance the rubber band travels after being released. One such experiment is the effect of heat on a rubber band.

In the end you should have one graph with three lines each representing a different trial with a different rubber band. Make a line graph of the rubber band stretch length y axis vs. Stretch your science knowledge with this experiment that defies the laws of physics. The mass hanger is hung from the band and an measurement of extension taken.

The rubber band changes temperature for a different reason 1 than the traditional heat pump but the effect is easy to sense and the test equipment doesn t require a. To see this in action begin by suspending a rubber band vertically then attach a weight to it. The gap between the two marks will denote the extension value and so one mark should be drawn near the top and one near the bottom of the band. But just how much energy does a rubber band have.

If you have conducted this experiment correctly you will notice the band s temperature rise when you stretch it and you will notice the temperature drop when you relax the band. Supplies an empty 2 liter soda bottle permanent marker scissors pencil small thin rubber band a handful of quarters 20 25 tape paper clip hot tap water ice cubes large shallow. You want the rubber band to visibly stretch out when you hang the quarters from it but not so much that it hits the bottom of the bottle. Shoot at least five rubber bands for each stretch length.

Measure carefully its stretched length with a ruler. A strong rubber band may require more quarters a weaker. Will heat make a rubber band expand and get longer or contract and get shorter. The rubber band is hung from the clamp stand and two points are marked on the band with the pen.
