Activity: Kaboom!
By Jonathan Tilly

“Because it was travelling so fast, it heated up the air in front of it to thousands of degrees while the back side of it was still cold—as cold as space, where it came from. It slowed down so quickly that it got squeezed, which caused it to explode outwards, high in the sky…”

  1. How does the particle theory help explain the meteorite explosion?
  2. Create a labeled diagram to illustrate your explanation.

Curriculum Connection
Use the particle theory to compare how heat affects the motion of particles in a solid, a liquid, and a gas (OME, Science: 3.1).
