Chemical Bonding, Reactions, and Families of Chemicals
by Gerry Tessner
Bear Creek Middle School,Fairburn, GA
designed for 8th grade Physical Science.
The student will be able to: define chemical bonding and describe ionic, covalent, and metallic bonds; predict the formation of compounds between elements; describe the parts of a chemical reaction and the factors that affect the rate of a reaction; describe the characteristics of the various types of reactions and give examples of each; state the properties and structures of the families of chemical compounds.
You will choose from the following 3 areas to determine your grade. Each area, except labs, will go into your notebook and must be listed on your table of contents. Labs will be turned in with the coversheet/checklist as usual. Points given are for completion and accuracy.

Area III: CHOOSE ONE ONLY/25 points
Write an essay that clearly shows you understand the material in these
1. New medicines frequently appear on the market. Find out how chemists
experiment to develop new drugs and what testing procedures are used. Are
the procedures too strict? Why or why not?
2. A tremendous amount of money was spent on the restoration of the Statue
of Liberty. Much of this money was raised by a foundation comprised of
private citizens who devoted a great amount of time and energy to the
Do you think such a great expenditure of money and effort worthwhile, or
could it have been better spent on other things? Take a stand on this
and present arguments to support your position.
3. Acidic substances released into the atmosphere by certain industries can
eventually result in acid rain, which is destructive to many plants and
animal life forms. What can be done about this problem?
4. Many people believe that life based on hydrocarbons may exist on other
planets. Others disagree. Still others believe that the silicon-based
organisms may exist on other worlds. What is your opinion?
