This project demonstrates the law of conservation of energy through compressing cotton balls. This is displayed through the driving question, which happens to be: what causes bits of cotton inside a small tube to ignite when you quickly compress the air inside the tube? Not only does it demonstrate the law of conservation of energy but it also demonstrates the conservation of momentum, potential and kinetic energy, and the laws of thermodynamics.
What causes bits of cotton inside a small tube to ignite when you quickly compress the air inside the tube?
