Organic Compounds & Their Effects on Society

Scenario
|
Are organic chemicals more beneficial than harmful to
society? This is the question you and your co-workers will debate. You are
all working for a company that analyzes future trends in industries and
helps chemical industries make decisions about: production methods and
alternative processes that are available; and materials that deliver the
properties needed but at the same time are environmentally friendly.
Your company president, after reading reports about the
effects of organic chemicals on the environment, has decided that everyone
in the company should research organic compounds. A debate between
co-workers will then be held as to whether organic compounds are
beneficial or harmful and whether chemical industries should continue to
focus on organic chemicals or should they be researching alternatives. By
doing this, everyone in the company will participate in the
decision-making process.
- For this debate, each worker will research one specific chemical and
write a brief report about the properties, structure, and synthesis of
this chemical and also describe any problems or benefits associated
with its use.
- Each team will prepare for the debate by preparing supportive
arguments for each side of the issue and will write a paper
summarizing their position on the issue after the debate.
Part A: Research
First, divide into teams of three or four people. Each
team is responsible for one of the following categories:
Food additives |
Fuels |
Plastics |
Cleaning products |
Herbicides |
Cosmetics |
Lubricants |
Pesticides |
Bisphenol |
Pharmaceuticals |
Paints/solvents |
Teflon |
-
Within each category or team, each person will select
one chemical and use a variety of resources to describe:
- the formula of the chemical and in what products is the chemical
found: around the house or in industry?
- the raw materials used, their cost and processing requirements
- how the chemical is made, including word and balanced chemical
equations
- the problems and benefits associated with this chemical.
- the technologies involved in production
-
Summarize your results in an appropriate format.
Part B: Testing and Inquiry
- Design a set of procedures to test the physical properties of your
chemical. Outline your expected observations and explain your
predictions based on the chemical’s structure. Check with your
teacher and if possible, look at products that contain this chemical
and note its physical properties. Are they similar or different than
those predicted for the chemical? Explain similarities and
differences.
- Design a set of procedures to test the chemical properties of your
chemical. You will need to review or research the chemical properties
of hydrocarbons and also other families of organic compounds. Check
your procedures with your teacher. Outline your expected observations
and explain these predictions based on your research.
Part C: Analyze and Reflect
-
Prepare tables to summarize your procedures, predicted
physical and chemical properties, and explanations of those
properties.
-
In your teams, share the information you found about
you chemical. Prepare for the debate by organizing all your
information into supportive arguments for each side.
Part D: Communicate
Before the debate, each person will prepare a report that
should include:
- an introduction
- a summary recorded in an appropriate format of: the formula of the
chemical and in what products is the chemical found; the raw materials
used, their cost and processing requirements; how the chemical is
made, including word and balanced chemical equations; the problems and
benefits associated with this chemical; and the technologies involved
in production
- a table summarizing your procedures, predicted physical and chemical
properties, and explanations of those properties
- a conclusion that considers the benefits versus the problems of
using this chemical
- all references used listed in APA style
After the debate, each team will meet and review the
question of whether organic chemicals are more beneficial or harmful to
society and whether chemical industries should continue to focus on
organic chemicals or whether they should be researching alternatives. The
team should arrive at a position that is agreed upon by all members and
then write a brief summary of this position, supported by arguments from
the debate or research.
