1. What is matter? Anything that has mass and takes up space. Everything around you.

2. What types of matter do you see?

3. How would you classify the matter in this picture?

4. Pure substance or a mixture? A sample of matter is either pure: – made up of only one kind of matter Mixture – made up of different kinds of matter.

5. Substance – Matter, either an element or compound, with the same fixed composition and properties (water) Pure Substance – Has a uniform and unchanging composition

6. Pure Substances Atom: –the smallest particle of an element

7. Pure Substances Element –has a fixed composition because it contains only one type of atom –No two elements contain the same atoms. –They are listed on the Periodic Table of Elements

8. Elements Most elements (100) are solids at room temperature (20°C). 11 are gasses. 2 are liquids. All elements are represented by symbols

9. Compounds/Mixtures Compound – – is a substance that can be broken down into simpler substances. The simpler substance is either are either elements or other compounds. –Ex. H 2 0 → H 2 + 0 2

10. Physical Property a characteristic of a material that can be observed or measured without changing the composition of the material

11. Physical Properties Extensive properties –Dependent upon the amount of the substance present –Mass, length, and volume Intensive properties –Independent of the amount of substance present –Density is the same is the same no matter how much is present

12. Physical Property Density (m/v) Color Odor Taste Hardness Melting point Boiling point

13. Physical Property Viscosity – Tendency of a liquid to keep from flowing. –Higher viscosity, slower the fluid moves.

14. Physical Property Conductivity – A materials ability to allow heat to flow.

15. Physical Property Conductivity – A materials ability to allow heat to flow.

16. Physical Property Malleability – the ability of a solid to hammered into sheets

17. Physical Property Hardness – Based on if one object can scratch another.

18. Physical Property Melting and Boiling Points- –M.P. – Solid to Liquid –B.P. – Liquid to Gas

19. Physical Properties Filtration – a process to separate materials based on their size Examples: coffee filters a screen to find artifacts at a historical site

20. Physical Properties Distillation – a process that separates substances in a solution by using their boiling points

21. Chemical Properties an ability of a substance to combine with or change into one or more other substances

22. Chemical Properties Flammability – a materials ability to burn in the presence of oxygen

23. Chemical Property Reactivity – the property that describes how readily a substance combines chemically with other substances

24. Sodium, reacting violently with water http://ruminatingdude.blogspot.com/2005/08/justifying-what-we-teach-in-hs.html?

25. Recognizing Chemical Change A chemical change –when a substance reacts and forms one or more new substances

26. 3 Common Types of a Chemical Change 1.A change in color. 2.Production of gas. 3.Formation of a Precipitate.

27. –Precipitate is a solid that forms and separates from a liquid mixture.

28. Physical or Chemical
