Organic Compounds

  1. 1. The Amazing World of Organic Compounds!
  2. 2. <ul><li>Time to “Test” last year’s knowledge </li></ul><ul><li>Create a KWL Chart </li></ul><ul><ul><li>What do you know? </li></ul></ul><ul><ul><li>What would you like to know? </li></ul></ul><ul><ul><li>What did you learn? </li></ul></ul>
  3. 3. KWL Chart Know Want to Know Learned
  4. 4. <ul><li>Identify that Organic compounds contain Carbon </li></ul><ul><li>Distinguish between Organic and Inorganic Molecules </li></ul><ul><li>Analyze various compounds present in living organisms </li></ul>
  5. 5. <ul><li>VIDEO! http://www.youtube.com/watch?v=ypbb9Zi5Tao </li></ul><ul><li>Be prepared to share ideas </li></ul>
  6. 6. “ Refreshing Activity” Example Element Compound Mixture Water X Air Lead Sugar Gold Chalk Chlorine Baking Soda Ocean Water Hydrogen Smog Salt Potassium Dust
  7. 7. An organic compound always includes carbon joined to either itself or hydrogen. Inorganic Organic Carbon Hydrogen Hydrogen Hydrogen Hydrogen
  8. 8. When two or more elements combine together it is called a compound. Compounds can be classified into two main groups: inorganic and organic. Inorganic Organic Carbon Oxygen
  9. 9. The Importance of Carbon … but not every compound containing carbon is organic. All organic compounds contain carbon... Inorganic Organic
  10. 10. Organic Compounds Club MEMBERS ONLY <ul><li>phosphorus </li></ul>Other Elements in Organic Compounds <ul><li>oxygen </li></ul>Other elements can be in organic compounds such as: <ul><li>nitrogen </li></ul><ul><li>sulfur </li></ul>Carbon and hydrogen are not the only elements that might be in organic compounds.
  11. 11. Importance of Carbon <ul><li>Carbon has the ability to join with several chemicals at the same time. </li></ul><ul><li>It can also join with itself easily. </li></ul><ul><li>Carbon comprises about 19% of the weight of an animal and about 12% of the weight of a plant. </li></ul>
  12. 12. All these elements could be present in Organic Compounds! Element Symbol Atomic number Metal or Nonmetal Carbon Hydrogen Oxygen Nitrogen Phosphorus Sulfur
  13. 13. <ul><li>Lets classify different compounds! </li></ul><ul><li>What are your 4 classifications? </li></ul><ul><li>Which compound did you place under each category? </li></ul><ul><li>Why did you place them under that category? </li></ul>
  14. 14. <ul><li>What do you know about the word MONO </li></ul><ul><li>What do you know about the word POLY </li></ul><ul><li>Mono-mers and Poly-mers </li></ul><ul><ul><li>A molecule that may react chemically to another molecule of the same type to form a larger molecule . </li></ul></ul><ul><ul><li>Then what’s a Polymer? </li></ul></ul><ul><ul><ul><li>Made from monomers linked by chemical bonds and make a compound. </li></ul></ul></ul>
  15. 15. <ul><li>Lets use our compounds to differentiate between Monomers and Polymers </li></ul>Which you think is the Polymer?
  16. 16. <ul><li>Think about what you learned today! </li></ul>Don’t forget the KWL CHART!
  1. A particular slide catching your eye?

    Clipping is a handy way to collect important slides you want to go back to later.
