3 take one rubber band from the three and cut it at a point.
The hypothesis was supported by our experiment.
Results table graph summary of results.
The heated rubber bands were the most elastic.
Does cold temperature affect the elasticity of a rubber band.
2 place the first three rubber bands in a room temperature for 10 minutes.
Introduction background statement of the problem hypothesis.
The rubber bands were suspended from a secured pencil and 400g of weight were hung from the pencil.
Elasticity of a rubber band.
Rubber 1 was not as slack as thin and had a smaller circumference than rubber 2.
Use a spring scale to measure the maximum force that a rubber band can withstand before breaking.
How does the rubber band feel now.
For each temperature we collected data for two colored rubber bands and two natural rubber bands.
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.
Kimberley answer yes a rubber band will actually become softer or easier to stretch when the temperature gets colder.
Record your data in your notebook.
When the rubber bands were attached to the flags the total circumference of the rubber bands then became 0 30 m 0.
Then measure the length of the rubber band with the ruler.
After 15 minutes remove the shoebox and measure the length of the rubber band again.

Allow the rubber band to stretch for three minutes at room temperature.
Rubber band elasticity and temperature from science buddies science activities for all ages from science buddies.
50 m and the increase in length of the rubber band was different dependent on which rubber band was used see table.
