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. 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
