Elementary Pollute It
How do plants help provide us
with clean air?
Plants breathe in Carbon dioxide
(CO2) and out Oxygen (O2). Plants
filter the air for us and provide us
with the oxygen we need to
breathe.
True or False?
Indoor air can be as bad or worse
for you than outdoor air.
True: Since buildings are built tighter
(more energy efficient) these days,
pollutants can become trapped inside.
Which causes more air pollution.
cars or factories?
True: 60% of our air pollution
comes from the cars we drive.
What does an anemometer do?
Measures wind speed.
What does the ozone layer do?
The ozone layer is found in the upper
atmosphere (stratosphere) and it
filters out harmful ultraviolet rays
What does AQI stand for?
Hint: An AQI is like a weather forecast
that we check to see how much air
pollution is expected today.

What do the Initials CFC
stand for?
Hint: This is the chemical that tears
apart ozone in the atmosphere and
creates the “hole in the ozone layer”.
Chloro-fluoro-carbon
What does IAQ stand for?
Hint: With IAQ you are concerned with
mold, radon, and second hand smoke
Indoor Air Quality
What do the initials EPA
stand for?
Hint: This is the government agency
that protects human health and the
environment.
Environmental
Protection Agency
If I told you that the wind was
blowing 25mph, what does the
mph stand for?
Miles per hour
What element is most common
in the air we breathe?
Nitrogen
78% Nitrogen
1% other stuff
20.8% Oxygen
0.2% Carbon Dioxide
What is the chemical that we
need to breathe from the air?
Oxygen
(O2)
What is the chemical protects
us from the sun?
Ozone
(O3)
What naturally occurring
radioactive gas is found
underground that can leak into
your house and cause health
problems?
Radon
True or False:
Carbon monoxide is not harmful.
False

What is the result when water
droplets in the air combine with
air pollutants (like ozone)?
Smog
What term do we use for the phenomenon
where CO2, methane, and other gases
trap more than normal amounts of heat
inside the earth’s atmosphere.
Global
Warming
What chemical is linked to the
hole in the Ozone Layer.
CFCs (chlorofluorocarbons)
Where do excess greenhouse
gases that cause global warming
come from?
How does ozone get into the
troposphere (ground level)?
We call this “bad ozone.”
Burning fossil fuels: automobiles,
power plants, refineries
True or False: Oxygen gets to
the cells in your body by
absorbing through your skin.
False: Air, containing oxygen, is
inhaled through the mouth and
nose. The air travels to the lungs
and goes through a network of
branches. The oxygen is
absorbed into the blood stream
and travels to all parts of the
body. All other air components
(CO2, Nitrogen, etc) are exhaled.
Why is carbon monoxide
harmful to humans?
CO combines
strongly with red
blood cells
preventing them
from carrying
Oxygen to your
body
About how many times a day
do you take a breath?
22,000 respirations/day
Would it be healthy for humans to
totally get rid of the earth’s
greenhouse effect?
No! The
greenhouse
effect keeps the
earth at livable
temperatures
Humans breathe from this layer
of the atmosphere.

Bob’s best-friend? And what
