  1. What if your job was to organize everything in the world? How do you do it?

  2. Essential Question • What are common properties of matter?

  3. D Identifying the Unknown Patterns help scientists predict. Scientists noticed that liquids have more energy than solids. If you discovered a brand new liquid, you could assume that it could be cooled to form a solid, for example. Engage

  4. D A property is a characteristic that identifies a substance. A fingerprint is also like a property because it identifies people. The robber’s fingerprint identifies him. A fingerprint is a property of a person.

  5. The fox can be identified by the poo he dropped on the ground, so the poo is like a property of the fox. A property is a characteristicthat identifies a substance For example, poo-poo is a characteristic that identifies wild animals. Here is a chart that matches poo-poo to different animals.

  6. What does the word property mean • In math class? • In a Novel read in English class?

  7. A property is a characteristic that identifies substances, not people or wild animals.Melting point is a property of substances. For example, the melting point of gold is 1064.43 C or 1947.97 F In contrast, the melting point of gallium is 30 °C or 89 °F If the melting point of a metal is 1064.43 °C; that is a clue that it is gold. If a metal does not melt in your hand, it is not gallium.

  8. Common Properties of Matter • Volume – how much space a substance takes up • Mass and Weight – how heavy a substance is • Density – how tightly packed the molecules in a substance are: mass/volume • Color – Duh. • Boiling/Freezing/Melting Temperature – the temperature at which a substance will change states (boil from liquid to gas, freeze from liquid to solid, melt from solid to liquid)

  9. Special Properties of Matter luster Magnetism malleability plasticity tenacity Solubility viscosity Brittleness combustibility conductivity ductility elasticity flexibility hardness

  10. Combustibility • Ability to burn • Used for fuel

  11. Conductivity Ability to let heat and electricity pass through it Insulator: Resists heat and electricity

  12. Ductility • Ability to be drawn into finewires Copper is ductile

  13. Tenacity • Resists being pulled apart

  14. Elasticity • Ability to be stretched and return back to original shape and size For example: Rubber bands are Elastic

  15. Flexibility • Ability to bend without breaking • Example: paper clip, wire

  16. Brittleness • Easily breaks into pieces • Fragile/ delicate Brittle

  17. Malleability The ability to be hammered into thin sheets

  18. Plasticity • Ability to be shaped/molded in different ways • Example: clay

  19. Viscocity • Resists flowing (liquids) • Flows slowly • Example: corn syrup

  20. Solubility • Ability to dissolve in water or any solvent

  21. Magnetism • Ability to attract iron

  22. Hardness • Can resist being scratched by another material • Moh’s Scale of Hardness : Diamond scale 10 as the hardest mineral

  23. Luster • Shiny, ability to reflect light • Example: gold, silver, aluminum

  24. Some properties of elements are shown in the periodic table • Metals - shiny, malleable, ductile, good conductors, high melting pts., mostly solid • Metalloids- show some metal and some non-metal properties • Non-Metals - dull, brittle, non/poor conductors, mostly solids or gases
