CHEMISTRY & SOCIETY: MAGICIAN & AUDIENCE
by Ken Costello
|
|
INTRODUCTION:
The first two tutorials develop your skills at scientific skepticism.
|
PROBLEM WITH AUDIENCES
Audiences come to enjoy a performance.
Their frame of mind is to entertained. Not much interest is given
to what happened in preparation of the performance or what happens
after the performance. This makes them uninformed to the full depth
of what the performance really should mean to them. As citizens and
consumers we often have the same shallow insight as audiences. We
are focused just on the product, results, performance, or solution.
This makes us rather gullible and vulnerable.

WHAT
HAPPENS BEHIND THE SCENES
To gain the ability to see through tricks and to totally
evaluate what is being presented, we need to step behind the scenes.
This is true whether it's a card trick, a chemistry trick, or anything
in between.

Our Society had three problems which we solved
using chemistry; however, in doing so, we created new problems with
negative consequences. |
| Society
Problem #1: We want a multitude
of products that are cheap and readily available. |
|
Society's Solution:
Mass Production with global distribution of
products. |
| Positive
consequences: We are all materially very wealthy. Owning many
more things than our ancestors ever dreamed of. Because of mass production
of food products, we also have access to more food than our ancestors
ever dreamed of. |

Society Problem #2: Find raw materials
that allow easier and faster production of manufactured goods. (This
problem is related to problem 1) This material should be cheap, lightweight,
waterproof, inert, and moldable.
|
Society's
Solution:
Polymers: Chaining together simple molecules allows the creation
of a variety of materials known as polymers or plastics. These simple
molecules primarily come from petroleum.
|
|
Positive impact on society:
Plastics contribute to our material wealth because they
are cheaper to manufacture. Cars are lighter in weight and therefore
produce less pollution. Our clothes are warmer, last longer, and
are easier to care for. Things are cheap enough to be disposed of;
eliminating cleaning and use of water and soap. Plastics are waterproof
and are durable in all weather conditions. Plastic containers or
bags take up less space at home or in the landfill. Some plastics
can replace body parts. |
|
| Negative
consequences:
• Because of plastics' durability, they do not decompose
easily in landfills or as litter.
• Some plastic holders for beverage bottles have strangled
marine animals.
• Plastics are made from petroleum which is a limited
resource.

polymers.

and Find plastic items around the house that has
these codes and report what polymer code is printed on them. Give at
least three.
|
|
|
Society Problem #3:
For refrigeration, we need a gas that upon compression will turn to
liquid at room temperatures. It also cannot be flammable and should
be cheap to make.
|
Society's Solution:
Combine a few chlorine atoms, fluorine atoms, and carbon
atoms to make a variety of compounds called chlorofluorocarbons.
|
|
| Positive
Impact on Society: The comfort of refrigeration was enjoyed
in homes, cars, businesses, and elsewhere. This gas was also used
to make refrigerators and freezers. Chlorofluorocarbons were useful
in spray cans, the making of Styrofoam and other foam-like plastics, fire
extinguishers, cleaning solvents, and other products. It had
a huge positive impact on society, which is why accepting its negative
consequences was difficult. |
|
|
Negative consequence: The chlorofluorocarbons
worked their way into the upper stratosphere and destroyed ozone, which
blocks the sun's high energy ultraviolet light. Excess ultraviolet
light damages skin, breaks DNA, causes skin cancer, damages eyes, kills
plants, and causes many more problems. Life on Earth will cease to exist
if too much UV light gets through the atmosphere. A hole
in the ozone layer around the south pole has grown to 10 million square
miles (twice the size of United Sates). People in Antarctica and
southern tip of South America are now warned to wear thicker clothing
for protection. The ozone level over the whole Earth has also
dropped.
