Presentation Transcript

  1. Modified from power point created by Russell Capps @ Chisholm Trail Middle School: www.nisd.org • Use as and introduction to organic compounds – have materials available for students as you present the power point and have students complete the worksheet. • Then use ppt. Elements in Organic Compounds

  2. A COMPARISON TEKS focus (7.6) Matter and energy. The student knows that matter has physical and chemical properties and can undergo physical and chemical changes. The student is expected to: (A) identify that organic compounds contain carbon and other elements such as hydrogen, oxygen, phosphorus, nitrogen, or sulfur;

  3. Alwayscontain Carbon- usually carbon/hydrogen bonds Molecules typically have asymmetrical structures & complicated formulas Biotic:Essential parts & products of living creatures (remember carbon based life forms?????) Do not have to contain carbon Molecules typically have symmetrical structures & more simple formulas Abiotic. Often mined from the earth OrganicorInorganic?

  4. Aluminum Foil • Composition: • Thin sheets of • Pure aluminum metal Origin: most abundant metal in the earth’s crust Chemistry Formula:Al Structure: INORGANIC

  5. Nail Chemistry Formula:Fe3C Structure • Composition: • Wrought Iron- A metal alloy Origin: Iron Ore mined from the earth INORGANIC

  6. Salt INORGANIC ChemistryFormula:NaCl Structure : Composition:Sodium Chloride (sodium & chlorine) Origin: Compound found in crystal form. Obtained from mines in the ground or from evaporation of sea water.

  7. Glass Marble ChemistryFormulaSiO4 Structure Composition: Soda glass is mostly made of silica INORGANIC Origin: Glass formation begins with heating and purifying grains of sand

  8. Crackers ORGANIC Composition: Crackers are primarily flour which high in Starch Carbohydrates Chemistry of Starch Formula: n(C6H10O6) Structure: Origin: Flour is processed wheat or corn

  9. Half & Half ORGANIC Composition: In addition to many other macromolecules; half & half has a high lipid (fat) content Chemistry Formula: CH3(CH2)10CO2H Structure: Origin: Half & half is a milk product typically obtained from dairy cows

  10. Legume ORGANIC Composition: In addition to many other macromolecules, legumes are high in the amino acid lysine Chemistry of Lysine: formula:C6H14N2O2 Structure Origin: Legumes are plants that grow pods possessing beans or peas

  11. ORGANIC Leaf Chemistry Formula: C55H72O5N4Mg structure : Composition: A leaf is composed of many macromolecules, including chloropyll, a chemical essential for photosynthesis Origin: Leaves are found on most photosynthetic plants
