Organic macromolecules

Matter consists of chemical elements in pure form and in combinations called compounds. Water is the universal medium for life on Earth, and Carbon in the backbone of life. Carbon enters the biosphere trough the action of plants and it is able to form molecules joining with elements such as Oxygen, Nitrogen, Sulphur, and Phosphorus to form organic macromulecules which compose living organisims.

Instructions: in this web quest you will find questions about the conformation, structure, and function of organic macromolecules. At the end of these questions, you will find a link that may help you with the answer. Open a word document and identify it with your complete name. When you are done answering the web quest sent it to your teacher: vanevet77@hotmail.com

Evaluation:
You will be graded as follows (rubric description):
Ø Followed instructions precisely: Student followed all directions given by the teacher at the beginning of the class. (20 points)
Ø Quality of writing: There is a thesis that summarizes upcoming content. Grabs the reader’s attention uses proper vocabulary terms for the science content, correct punctuation and grammar (20 points)
Ø The question is answered correctly and in a concise and clear matter (20 points)
Ø Usage of Internet addresses and info: uses the specific address that is published and if not cites the author or source (20 points)
Ø Completeness: The work is finished completely at the end of the 45 minute period class. If not, it will be graded according to how many questions are answered of the total (20 points)
TOTAL. 100 points
