What is matter? Matter is everything that is around you. It has atoms and molecules and mass. Matter comes in three different states: solids, liquids, and gases. During this unit, you will develop a better understanding of matter and why it matters through lessons and experiments.


Students will understand that physical and chemical changes occur in matter by:
*describing that matter is neither created nor destroyed even though it may undergo change.
*evaluating evidence that indicates a physical change has occurred.
*investigating evidence that matter has changed in a chemical reaction.
