Outcome (circle the verb and underline the qualifiers)
ES20-AS1 – Assess the impact of air quality on human and environmental health and the need for regulations and mitigating
technologies.
KNOW
UNDERSTAND
BE ABLE TO DO
Key vocabulary – pollution, mitigating, air quality,
ozone layer, volatile, allergens, stratosphere,
troposphere, particulates, emissions, population
density, regulations, contaminants, cataracts
Prior knowledge – sources of air pollution,
atmospheric layers, collecting and analyzing data,
human health issues
Concepts/ Skills to be learned – posing
questions, investigate, explain and support,
collecting and analyzing data, recognize impacts,
examine principles, develop generalizations
Examples of contaminants - as radon, carbon
monoxide, mold, volatile organic compounds,
allergens, and particulates
Troposphere contaminants - ozone,
particulates, carbon monoxide, nitrogen oxides,
lead, and sulphur dioxide
Government regulations - Air Quality Health
Index (AQHI) and the National Ambient Air Quality
Objectives (NAAQOs)
Technologies - as air scrubbers, baghouse filters,
electrostatic precipitators, and catalytic converters
The students will
understand that:
 Human activities and
technology influence air
quality
 Ozone depletion
contributes to health
issues
 Indoor air quality can be
influenced by a variety of
air contaminants
 Human health and the
environment are
connected
 There are groups
devoted to reducing the
effects of poor air quality
 Air quality can be
improved
 There is a connection
between human
population and air quality

Pose questions regarding how human activities and
technologies have influenced air quality (e.g., Is air pollution
necessary? What regions of the world are most polluted and
why? What are some local sources of air pollution?)
Investigate the role of stratospheric ozone layer depletion as a
contributor towards human health issues such as cancers and
cataracts.
Explain how contaminants affect indoor air quality
Design and carry out a process for collecting and analyzing
data to assess air quality.
Identify how contaminants in the troposphere can affect human
health and impact the environment
Recognize the impact of government regulations on minimizing
risks to environmental and human health.
Examine scientific principles of technologies have been
developed to reduce contaminants in motor vehicle and
industrial emissions.
Investigate processes designed to manage and improve indoor
air quality in residential, commercial, and industrial buildings
and structures in order to minimize damage to human health.
Develop a generalization about the relationship between
human population density and air quality.
ESSENTIAL QUESTIONS
How do humans impact air quality? And how is all of this connected to environment? How does human population factor in?
Why does air quality matter? How can it be improved?
Why is ozone depletion such a big deal?
What kinds of contaminants impact air quality and how does this happen?
Who is working on air quality issues?
