Matter can undergo a variety of changes.
When matter is changed physically, generally no changes occur in the structure of the atoms or molecules composing the matter.
When matter changes chemically, a rearrangement of bonds between the atoms occurs. This results in new substances with new properties.
Differentiate between physical changes and chemical changes.
Investigate and describe how temperature influences chemical changes.
