• 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
