Air Pollution

molecules per million air molecules. Many come from directly identifiable
sources; sulfur dioxide, for example, comes from electric power plants burning
coal or oil. Others are formed through the action of sunlight on previously
emitted reactive materials. For example, ozone, a dangerous pollutant in smog,
is produced by the interaction of hydrocarbons and nitrogen oxides under the
influence of sunlight. Ozone has also caused serious crop damage. On the other
hand, the discovery in the 1980s that air pollutants such as fluorocarbons are
causing a loss of ozone from the earth's protective ozone layer has caused .....

Hydroponics
Words: 1002 - Pages: 4.... Not only dose hydroponics produce bigger, better, and more
healthier plants than the traditional dirt, but it can also be greatly
beneficial on things like submarines, space stations, off-shore oil rigs, or any

During this experiment we'll be looking for which plant life well do
best with hydroponics, by measuring which plant has grown the highest or
bushiest. We also well be looking for green and healthy looking leaves on the
plants. We have no idea what the results might be, so this should be an exciting
experiment.
Problem
Which form of plant life will thrive the most in a hydroponics
