this lesson students will apply their understanding of
weather systems, air currents, and pollution to create
an informational poster that will be presented in a mini
Purpose – To
apply knowledge and skills to create posters that inform
the public about a specific pollutant
and suggest where people with specific respiratory illnesses
might want to relocate in order to alleviate symptoms.
Students will be able to:
i. Explain how a pollutant affects their community.
ii. Propose one solution to the problem.
iii. Make a recommendation where highly sensitive groups
should relocate in order to alleviate symptoms.
Standard D - STRUCTURE OF THE EARTH SYSTEM
The atmosphere is a mixture of nitrogen, oxygen, and trace
gases that include water vapor. The atmosphere has different
properties at different elevations. Clouds, formed by the condensation
of water vapor, affect weather and climate.
Content Standard D - EARTH IN THE SOLAR SYSTEM
The sun is the major source of energy for phenomena on the
earth's surface, such as growth of plants, winds, ocean currents,
and the water cycle. Seasons result from variations in the
amount of the sun's energy hitting the surface, the tilt of
the earth's rotation on its axis and the length of the day.
Arizona Science Education Standards
Strand 6 - EARTH SCIENCE
Concept 1 – Structure of the Earth
PO 1. Describe the properties and the composition of the layers
of the atmosphere.
PO 5. Describe ways scientists explore the Earth’s atmosphere
Concept 2 – EARTH’S PROCESSES AND SYSTEMS
PO 5. Analyze the impact of large-scale weather systems on
the local weather.
This lesson was created with Tucson, Arizona in mind,
but issues of air quality affect many cities across
the United States. For more information on your local
environment contact the local department of environmental
of Tucson have higher concentrations of different pollutants.
Particulate matter tends to have
a higher concentration on the Northwest side of town due
to the prevailing winds that blow from the Southeast. Carbon
Monoxide tends to be highest near 22nd Street and Alvernon
due to the high traffic volume. Downtown also shows a higher
level of CO (although both locations are below the national
maximum allowable concentration). Carbon Monoxide levels
are higher in the winter months due to inversion layers.
Ozone levels are relatively consistent across the city,
but slightly higher levels were noted near 22nd Street
and Alvernon and at the Children’s Park in the River
and La Cholla area. Ozone levels are highest in the summer
months due to increased daylight hours.
