By the end of the day today: I will be able to analyze a change in matter and determine if it is a chemical or physical change

 Matter can change  Examples: Freeze, cut, burn, etc.  2 types of changes 1. Physical changes 2. Chemical changes

 Definition: when the state or form of matter is changed without changing its chemical composition.  Examples: cutting, freezing, melting, etc.

 Definition: takes place on a molecular level and produces a new chemical substance.  A chemical change always involves a chemical reaction.

 Evidence of a chemical change:  color change, gas production, and release of heat, light, odor, or sound.  Examples: Burning (combustion), rusting, tarnishing and fermenting

 Talk over scenario with your desk partner(s).  Write either C or P on your white board.
