Physical and Chemical Changes of Matter

A physical change is a change of matter from one state (form) to another.

Examples
  • ice cream melting
  • liquid water freezing and becoming solid ice
  • cutting wood
  • clouds forming in the sky 




A chemical change is a change that forms a different kind of matter.

Examples: 
  • baking a cake
  • burning wood
  • a nail rusting
  • photosynthesis




Here's a really cool video from Scholastic on Physical and Chemical Changes of Matter. Plus there is a follow-up online multiple choice test that the kids can take after watching the video.
