The
following question is increasingly asked by everyone as the
rates of children affected by asthma increase.
The quality
of air impacts human health dramatically and in turn humans affect
air quality. The relationship between air
quality
and human health is pointedly clear in this unit as students
explore the built community, buildings, highways, and industrial
parks, plus environmental and human health.
Using city
designs from across the globe students investigate the properties
of air and how a city’s physical layout and growth can
impact air quality. Human health is an important
consideration in city planning. Links between air pollution and
such illnesses as asthma and allergies have been established
by biomedical researchers.
The amount
of air pollution present in a city is affected by the weather
and air flow, human construction,
and traffic patterns in that region. Through this unit, students
build their understanding of how city development, air movement
and air quality all contribute to respiratory illnesses. They
demonstrate their grasp of this topic via their design of a “healthy
air” city located in one of ten locations where large cities
exist today.
This unit
addresses the education standards for 9th grade.

Major
Project
Students take on the role of city planners as they design a healthy city. Using
the
actual physical geographical location of major cities, they develop a scaled
model of a city including the zones within
a city. Students focus on excellent air quality as a feature of a healthy city
and using their understanding of climate, weather, and air movement, design their
city accordingly.
In science class, students will discover the following to
prepare them to consider these concepts in the major project:
- How winds
and water can carry pollutants in predictable paths following
currents
- How geography
affects climate
- How
microclimates can be affected by geography and human construction
In language
arts, students work with non-fiction texts as they analyze historical
journals and literary
devices to uncover values and beliefs held by the authors.
Students
also
learn to write formal papers to prepare them for the
formal city proposal as part of
the major project.
Finally, in
social studies, students will learn about human settlement,
city design and how physical systems
impact
human systems as they
design and construct a scale model city conducive to air quality
health.
