  2. Objective: • Be able to distinguish between a physical and chemical change. • Physical and Chemical Change Introduction • Physical and Chemical Change Activity Agenda:

  3. Physical and Chemical Changes

  4. What is a Physical Change? • A physical change alters the form of a substance, but does not change it to another substance. Example: Making Orange Juice

  5. What is a Chemical Change? • When a substance undergoes a chemical change, it is changed into a different substance with different properties. Example: Baking a Cake

  6. 5 Signs of a Chemical Change • Color Change • Precipitation

  7. Precipitation • Precipitation – the solid that forms from a solution during a chemical reaction. • It looks like a cloudy solid in an otherwise clear solution.

  8. 5 Signs of a Chemical Change • Gas Production • Temperature Change

  9. 5 Signs of a Chemical Change • Changes in Characteristic Properties (odor, light given off)
