Topic of Research (Chun Leong) -- Rubber bands for energy

Topic Overview
------------------------------------------------------
Rubber bands for energy

Time Required
Very Short (≤ 1 day)
Prerequisites
None
Material Availability
Readily available
Cost
Very Low (under $20)
Safety
No issues

Abstract

If you've ever been shot with a rubber band then you know it has energy in it, enough energy to smack you in the arm and cause a sting! How can the energy of a rubber band be put to work? 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

In this experiment you will investigate how the distance of stretch in a rubber band at rest relates to the distance the rubber band travels after being released.

Hypothesis and Variables
------------------------------------------------------
Hypothesis:
The longer a rubber band is stretched at rest, the further it will travel when released.

Dependent variable:
+ The distance the rubber band travels

Independent variable:
+ The distance of stretch in a rubber band

Constant:
+ The type of rubber band used


Research Questions
------------------------------------------------------
1. Where does the rubber band get the energy from?

2. What does the energy do?

3. Is there a maximum that the rubber band can be stretched?

4. How will the experiment be carried out?

5. Are there any current research about the same topic going on?

6. What equipment do you need?
