Chemical and Physical Changes

Chemical changes are changes in a substance that makes a whole different substance. For example, 2 hydrogen atoms plus 1 oxygen atom make water.

Or carbon dioxide, 2 oxygen atoms plus 1 carbon atom.

Physical changes are changes in the way a substance looks. For example, if you make a golden crown.

Or a banana ripening.

And now that you know what physical and chemical changes are, you can tell if a change is a physical or chemical change.
