Chemical and Physical form

WALT: Understand the difference between a chemical and physical change.
Today we were learning about how matter changes the matter of the material and we were also learning about the chemical and the physical state of matter and how it changes if you applies heat or applies any other substance to the matter. We were also learning how it is often that the physical form is often reversible and it is the same as the chemical form of matter and to see if it would return to its normal state of the chemical matter.
