Ozone
Click on: Good Up High Answer the following questions in your own words: (On separate piece of paper)
1: How can ozone be both good and bad?
-The good ozone is the one the traps the suns rays and warmth, the bad ozone is an air pollutant that is harmful for us.
2: What is happening to the “good” ozone layer?
-The good ozone layer is gradually being destroyed with the conduction of chemicals released in the air by us.
3: How much damage can 1 Chlorine atom do? Explain.
One Chlorine atom can destroy 100,000 "good" ozone molecules.
4: How does the “good” ozone protect the Earth?
-it protect the earth because it protects it from not getting too much uv light for the world to not be good enough to live in and have life
5: What is being done about ozone depletion?
-adopted a treaty called the Montreal Protocol to phase out the production and use of ozone-depleting substances.

1: What causes “bad” ozone?
- is created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOC) in the presence of sunlight.
2: What are some sources of bad ozone?
-Motor Vehicles
-Utilities
-Industrial
3: How does “bad” ozone affect human health and environment?
-Breathing ozone can trigger a variety of health problems including chest pain, coughing, throat irritation, and congestion.
4: What is being done about “bad” ozone?
-Under the Clean Air Act, EPA has set protective health-based standards for ozone in the air we breathe.
5: What can we do/actions can we take to reduce our risks?
-reformatting fuels, use public transportation, the conversion of better usage of energy source
Ozone- Air Now Go to: www.epa.gov/airnow/
In the far right corner- choose “Ozone”- found under Air Quality Basics. Read about good and bad ozone and answer the following questions.
1: Where is the good ozone located and what is its function?
-Ozone occurs naturally in the Earth's upper atmosphere - 6 to 30 miles above the Earth's surface - where it forms a protective layer that shields us from the sun's harmful ultraviolet rays
2: What depletes good ozone?
-Man made chemicals are known to destroy this beneficial ozone
3: Where is the bad ozone located and what creates it? What does NOX and VOC stand for?
-In the Earth's lower atmosphere, near ground level, ozone is formed when pollutants emitted by cars, power plants, industrial boilers, refineries, chemical plants, and other sources react chemically in the presence of sunlight.
-oxides of nitrogen and volatile organic compounds
4: List three health problems associated with bad ozone. (Hint: You may need to go to Ozone and your Health- How can ground-level ozone affect your health?)
-irritation in the lungs
-irritation in the eyes
-some may cause asthma
5: Scroll down to the Air Quality Index Color Chart- Write down a one-word descriptor of each color code.

What is the current ozone reading for our area? _________ (use color code)
-moderate yellow
Go to: www.smogcity2.org
Instructions: Change the settings in “Smog City” and notice the effects that those changes have on the amount of “smog” the city produces and the air quality.
On your paper, take notes about what the various condition changes do to the AQI.
Which set of conditions produce the best possible scenario for the city?
-The temperature would be 80 and the AQI would be 22 with good air quality.
-This meant that the population was low with low number of cars in the road but the winds have to be high. It all depends on the balance.
Which set of conditions produce the worst scenario for the people, animals and plants of Smog City?
-The worst temperature showed was 110 and the AQI was 109
-At this point was when everyone was at the maximum where everything was so high. The funny thing was that it would just be bad for those who are sensitive to this type of air.
Summary: On your paper, write a 2-3 paragraph summary about what you have learned about ozone, ozone depletion, ozone destruction and air quality by completing this assignment. Make sure to use the new vocabulary that you have learned.
This week i learned a lot about the ozone and the benefit and cons. One thing that stood out was that ozone is good up there and bad down near us. It is bad down near us because we need have more oxygen than ever. The ozone once it builds up creates a thick layer which creates the suns rays to not be reflected back as much which creates the earth to warm up. This causes a lot of problems such as for people with asthma because all the air pollution the air gets trapped and it gets harder to breathe.(bag smog) The other problem that occurred was that the ice caps are melting that can cause a lot of problems. One of the problems would be the rise of sea levels. This is not good because the land that is at sea level can get flooded.
