Rubber band elasticity and temperature from science buddies science activities for all ages from science buddies.
Rubber band elasticity and temperature conclusion.
Does cold temperature affect the elasticity of a rubber band.
Introduction background statement of the problem hypothesis.
Elasticity of a rubber band.
Effect of temperature on the elasticity of a rubber band table.
Now put the shoebox into the refrigerator for 15 minutes.
Perform multiple trials with rubber bands at different initial temperatures.
50 m and the increase in length of the rubber band was different dependent on which rubber band was used see table.
After 15 minutes remove the shoebox and measure the length of the rubber band again.
This will be the main temperature for the experiment.
The heated rubber bands were the most elastic.
Results table graph summary of results.
When the rubber bands were removed from their apparatuses a measurement was taken pre stretching.
Kimberley answer yes a rubber band will actually become softer or easier to stretch when the temperature gets colder.
2 place the first three rubber bands in a room temperature for 10 minutes.
The effect of temperature on the.
The way to think of the elasticity is in terms of entropy which is basically a measure of disorder.
Use a spring scale to measure the maximum force that a rubber band can withstand before breaking.

Rubber 1 was not as slack as thin and had a smaller circumference than rubber 2.
How does the rubber band feel now.
Put another way since you re asking about elasticity in the context of a hot and a cold rubber band loaded by the same weight i should emphasize that one can t directly measure a system s stiffness by keeping the force constant and observing the displacement when changing other things.
When the rubber bands were attached to the flags the total circumference of the rubber bands then became 0 30 m 0.
Method materials procedure diagram.
The rubber bands in freezing water were the opposite with a stretching length of 9 50 o o5 cm 0 c.
40 m and 0.
Record your data in your notebook.
Do you think that the force required to break a rubber band will change with temperature.
This activity brought to you in partnership with science buddies.
The hypothesis was supported by our experiment.
The rubber bands were suspended from a secured pencil and 400g of weight were hung from the pencil.
1 take out rubber band from the box and group them into threes for three trials at each temperature.
Stretching to the farthest extends of 17 90 o o5 cm 100 c.
For each temperature we collected data for two colored rubber bands and two natural rubber bands.
Allow the rubber band to stretch for three minutes at room temperature.
Five shots with.
