Rubbing alcohol evaporates in your hand
A match is lit
Photosynthesis
Aluminum foil is cut in half
Two liquid chemicals are mixed together and a solid forms (precipitate) on the bottom of the beaker
Play-doh is molded into a new shape
Food is broken down into smaller particles in your stomach
Butter melts on warm toast
A bottle of water freezes in the freezer
Rust forms on a bike
