2.0 Atmosphere

Discussion for Teachers:

Definition: http://en.wikipedia.org/wiki/Atmospheric_sciences

Objectives:

1. Understand the role between the ozone and traffic emissions, which are a health hazard.
2. Research omissions from cars, carbon dioxide, and the greenhouse effect, and nitrous oxide which is depleting the ozone, risking the lives of all species’ existence on Earth.
3. Understand that other strong emitters of nitrous oxide are coal-burning, oil-burning, and gas-burning power stations.
4. Research products that reduce ozone such as Styrofoam Cups. Ozone takes 7-10 years to reach the ozone layer before it causes damage. Ozone mends itself by moving to where the greatest damage occurs, leaving holes behind. When the weatherman says there is a percentage reduction in the ozone where you are, this is very serious to all species.
5. Invent peaceful ways to help prevent further damage.

Key Concepts:

1. The Carbon Cycle
2. Greenhouse Effect

Vocabulary: ozone, atmosphere, air, oxygen, carbon, photosynthesis, respiration, global warming, ozone depletion, pollution, atmospheric stratification (the layers of the atmosphere)

There are many teachable moments while watching this video. Discuss which layers of atmosphere they’re traveling through, the composition and temperature of the atmosphere at the different layers, and what we might expect to see. In which layer can we find Ozone?

About 90% of the ozone in our atmosphere is contained in the stratosphere. “Stratosphere is the part of the earth’s atmosphere which extends from the top of the troposphere to about 30 miles (50 kilometers) above the Earth’s surface and in which temperature increases gradually to about 32° F (0° C) and clouds rarely form here.”  – http://www.merriam-webster.com/dictionary/stratosphere

IHTEC’s Program:
Butterflies’ Breath – This program is about rain forests which are the ‘lungs’ for Earth. It is hoped that students already understand photosynthesis.
