1. Physical and Chemical Properties

2. Physical Physical PROPERTY: A characteristic of a substance that can be observed without changing the substance into something else. Ex: length, color, shape, density, mass, volume, solubility,

3. Physical Physical CHANGE: A change that affects the form or appearance (i.e. size, shape or color) of a substance but does not affect its composition.

4. Chemical Chemical PROPERTY: A property used to characterize materials in reactions that change their identity.

5. Chemical Chemical CHANGE: A change in the chemical composition of a substance to produce a new material with new properties.

6. Evidence of a Chemical Change Production of Gas Change in Temperature Formation of a Precipitate Change in Color
