Rubber Band Stretch Experiment

Measure carefully its stretched length with a ruler.

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. Objective investigate how the distance of stretch in a rubber band at rest relates to the distance the rubber band travels after being released. Make a line graph of the rubber band stretch length y axis vs. Repeating the experiment a total of three times will help you determine if your findings are consistent and reliable.

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. After each launch have your helper. To see this in action begin by suspending a rubber band vertically then attach a weight to it. In this experiment you will find out how the stretching of a rubber band affects the amount of energy that springs out of it.

One such experiment is the effect of heat on a rubber band. But just how much energy does a rubber band have. While most objects expand when heated a rubber band contracts. 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.

Stretch your science knowledge with this experiment that defies the laws of physics. A strong rubber band may require more quarters a weaker. 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.

In the end you should have one graph with three lines each representing a different trial with a different rubber band. The rubber band is hung from the clamp stand and two points are marked on the band with the pen. The mass hanger is hung from the band and an measurement of extension taken. Will heat make a rubber band expand and get longer or contract and get shorter.
