Storyboard Text

  • You may be wondering what is a chemical change or what is a physical change, or what is this campfire classified as?
  • a physical change is where a substance is changing states and it can be reversed back like water turning to ice back to water
  • a chemical change is when a substance is mixed with another substance and makes a new substance that cannot be reversed back to normal
  • Therefore this campfire you see in front of me is a chemical change not a physical change
  • The reason behind it is because the wood burning cannot be reverted back to normal wood it will now forever stay as ashes
  • But if it were something like chopping the wood to get smaller pieces that would be physical
