Rubber Band Stretch Experiment

Shoot at least five rubber bands for each stretch length.

Rubber band stretch experiment.

After each launch have your helper. To see this in action begin by suspending a rubber band vertically then attach a weight to it. 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. The water temperature x axis.

Make a line graph of the rubber band stretch length y axis vs. In the end you should have one graph with three lines each representing a different trial with a different rubber band. The mass hanger is hung from the band and an measurement of extension taken. A strong rubber band may require more quarters a weaker.

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

Stretch your science knowledge with this experiment that defies the laws of physics. Objective investigate how the distance of stretch in a rubber band at rest relates to the distance the rubber band travels after being released. While most objects expand when heated a rubber band contracts. 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.

But just how much energy does a rubber band have. 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. Repeating the experiment a total of three times will help you determine if your findings are consistent and reliable. One such experiment is the effect of heat on a rubber band.
