1. Section 1: Physical properties of matter
Chapter 2: Matter Properties and changes

2. A) Physical Properties

3. 1) Matter: anything that has mass and takes up space

4. 2) Physical Properties: Properties that can be observed or measured without changing an object

5. a) Observable Properties: Size, Color and Smell

6. b) Measureable Properties: Melting and Boiling Point, Attraction to Magnets

7. 3) Texture: How the surface feels,eg. rough, smooth, waxy, powdery

8. 4) Malleability: ability of a substance to be hammered into thin sheets or shaped

9. 5) Ductility: ability of substance to be pulled into thin threads without breaking

10. 6) Brittle: Object break easily (opposite of malleable and ductile)

11. 7) Density: the amount of mass that fits in a given volume (mass / volume) d=m/v

12. 8) Buoyancy: The ability to float in a liquid or rise in a gas

13. a) Objects with a density lower than 1 float in water

14. a) Why do you think that happens?

15. b) Objects with a density greater than 1 sink

16. c) Gases with density lower than air rise

17. B) Physical Changes: change the physical properties of an object, but it does not become a different substance.

18. B) Physical Changes: change the physical properties not the substance.

19. 1) Example Paper cut into tiny bits
1) Example Paper cut into tiny bits. each piece is still paper, the size changed

20. 2) Example Erosion of large rocks and mountains turned into smaller pieces

21. 3) Aluminum rolled into sheet, changed its shape

22. 4) Copper pulled in threads for wiring
