  1. Physical and Chemical Properties MS-PS1-2 Big Picture MS-PS1-2 Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.

  2. Physical and Chemical Properties MS-PS1-2 Do Now If you were asked to describe an orange to someone who had never seen an orange, what would you tell the person? Write your response in yourscience journal.

  3. Physical and Chemical Properties MS-PS1-2 Objectives Identify physical and chemical properties of matter and how matter can undergo physical and chemical changes.

  4. Physical and Chemical Properties MS-PS1-2 Agenda • Today we will: • Watch a video on physical and chemical properties. • Complete a group activity worksheet. • Do an individual assessment worksheet. • Review and exit ticket.

  5. Physical and Chemical Properties MS-PS1-2 Vocabulary • physical property • chemical property • physical change • chemical change

  6. Section 2Physical Properties Chapter K1 Physical Properties • What Are Physical Properties? A physical property of matter can be observed or measured without changing the matter’s identity.

  7. Section 2Physical Properties Chapter K1

  8. Section 2Physical Properties Chapter K1 Physical Properties, continued • Identifying Matter You use physical properties to identify matter. • Density Density is the amount of matter in a given space, or volume. The two balls below have different densities.

  9. Section 3Chemical Properties Chapter K1 Chemical Properties • Comparing Physical and Chemical Properties You can observe physical properties without changing the identity of the substance. Chemicals properties are more difficult to observe. • Characteristic Properties The properties that are most useful in identifying a substance are characteristic properties.

  11. Section 3Chemical Properties Chapter K1 Chemical Changes and New Substances • What Happens During a Chemical Change? During a chemical change a substance changes chemical properties. • Signs of Chemical Changes Some common signs of chemical changes includes a change in color, odor, production of heat, fizzing, and so on. • Matter and Chemical Changes Chemical changes change the identity of the matter involved.

  12. Section 3Chemical Properties Chapter K1

  13. Section 3Chemical Properties Chapter K1 Physical Versus Chemical Changes • A Change in Composition Physical changes do not change the composition of a substance while chemical changes do. • Reversing Changes Many physical changes are easily reversed, but most chemical changes cannot easily be reversed.
