• 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
• Always contain Carbonusually carbon/hydrogen
bonds
• Molecules typically have
asymmetrical
structures &
complicated formulas
• Biotic:
Essential parts &
products of living creatures
(remember carbon based life
forms?????)
or
Inorganic?
• Do not have to contain
carbon
• Molecules typically have
symmetrical structures
& more simple formulas
• Abiotic. Often mined
from the earth
