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

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;

Organic or Inorganic? Always contain 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

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

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

Composition: Sodium Chloride (sodium & chlorine) Salt INORGANIC Chemistry Formula: 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.

Soda glass is mostly made of silica Glass Marble Chemistry Formula SiO4 Structure Composition: Soda glass is mostly made of silica INORGANIC Origin: Glass formation begins with heating and purifying grains of sand

Flour is processed wheat or corn 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

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

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

Leaf ORGANIC Chemistry Composition: Origin: 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
