  1. Classification of Matter Mr. Autieri Unit 2—October 18, 2011 Physical Science 2011

  2. What is Matter? • _________: Any substance that takes up space and has mass. What substances are not matter? • Light • ________ • Sound

  3. Define __________- The smallest building blocks of matter. • All ________ is composed of atoms • Atoms cannot be broken down into smaller pieces by chemical means

  4. A. Pure Substances-- • A ___________is one that has a uniform (same) composition throughout.

  5. A. Pure Substances-- • 1) Element: • Simplest form of matter consisting of ____________________________. • Cannot be broken down. • EX: copper, _____________

  6. _____ CO2 Water ____________ NaCl Sodium chloride Pure Substances 2) Compounds : _____________________ chemically bonded together. Examples:

  7. ___________ Can be decomposed into simpler substances by chemical changes _________ cannot be decomposed into simpler substances by chemical changes Pure Substances Same kind of particles throughout

  8. B. Mixtures • Variable combination of ___ or more substances that are not __________ combined. ______________ _____________

  9. Mixture • May be _________ into pure substances by ________methods. • Mixtures of different compositions may have widely different properties.

  10. Element Compound Mixture Which is it?

  11. MIXTURE PURE SUBSTANCE yes no yes no Is the composition uniform? Can it be chemically decomposed? Colloids Suspensions Check-in: Matter Flowchart MATTER yes no Can it be physically separated? Homogeneous Mixture (solution) Heterogeneous Mixture Compound Element

  12. Physical Separation Techniques • By eye • ___________ to separate solid and liquid • __________ or boiling to separate two or more liquids with different boiling points

  13. Types of mixtures • Homogeneous mixture -1 phase -substances are evenly distributed -Difficult to see one substance from another eg: sugar and water • Heterogeneous mixture -2 or more phases eg: oil and water, sand and water

  14. C. Types of Mixtures #1: Solution: Substances ____________ to form a _________________ mixture. very ________ particles (can’t filter) • EX: rubbing alcohol or Sugar and water

  15. C. Types of Mixtures #2. Colloid: ____________--mix together __________-sized particles EX: milk

  16. C. Types of Mixtures #3. Suspension: ______________--seperates into layers. _______ particles cloudy EX: fresh-squeezed lemonade

  17. C. Let’s practice…. Examples: mayonnaise muddy water fog saltwater Italian salad dressing

  18. The Grand Finale Examples: graphite pepper sugar (sucrose) paint soda

  19. Classifying Matter
