VOCABULARY
chemical change, physical change, chemical change indicator/evidence, physical change indicator/evidence, molecules,
atoms
1.) Chemical Change Indicator: Any observable event that shows a new substance has been created.
2.) Physical Change Indicator: Any observable event that shows the original substance is still present.
3.) Physical Change: A change where the atoms are in their original arrangement and the original substance is still
present.
4.) Chemical Change: A change to matter where the atoms have been rearranged and a new substance has been
formed.
5.) atoms: the building blocks that stay the same during a chemical change, but get rearranged during a chemical
change.
6.) molecules: the “packages” of atoms that will change during a chemical change, but stay the same during a physical
change.
7.) precipitate: This is a chemical change indicator that consists of the formation of a new solid substance
