Science Lesson #1

What is Chemical change?

• a change to a sample of matter in which some properties of the material change, but the identity of the matter does not.

• a change of materials into another, new materials with different properties and one or more than one new substances are formed

• Nothing changes

What is Physical change?

• a change to a sample of matter in which some properties of the material change, but the identity of the matter does not.

• a change of materials into another, new materials with different properties and one or more than one new substances are formed.

• Nothing changes
