Module 3 Assignment: Submit Variables, Operational Definitions, and Hypotheses
General Topic of Interest:
The impact of airplane emissions on the environment
Research Objective/Purpose:
The purpose of this study is to investigate the impact of airplane emissions on the environment
and to identify possible solutions to mitigate their effects.
Research Question(s):
How do airplane emissions contribute to climate change, and what is the magnitude of this
contribution?
Independent Variable:
Airplane Emissions - This variable represents the emissions that are released into the atmosphere
by airplanes, such as carbon dioxide, nitrogen oxides, and particulate matter (Filippone &
Parkes, 2021).
Dependent Variable:
Climate Change - This variable represents the long-term changes in the Earth's climate system,
including global warming, rising sea levels, and changes in precipitation patterns, that are caused
by the accumulation of greenhouse gases in the atmosphere, including those emitted by airplanes
(Lee et al., 2009).
3
Intervening Variable:
Atmospheric Chemistry - This variable represents the chemical reactions that take place in the
atmosphere between the emissions from airplanes and other gases, such as water vapor, ozone,
and methane, which can influence the magnitude and duration of their impact on climate change.
Moderating Variable:
Air Traffic - This variable represents the volume and distribution of airplane traffic across
different regions and seasons, which can affect the spatial and temporal patterns of emissions and
their interaction with the atmosphere.
The relationships among these variables are complex and multidirectional. Airplane
emissions are a primary cause of climate change, which in turn can feedback to influence
atmospheric chemistry and climate patterns. At the same time, atmospheric chemistry can affect
the persistence and composition of airplane emissions, as well as the radiative forcing of
greenhouse gases. Finally, air traffic can modulate the exposure of different populations and
ecosystems to airplane emissions, and the effectiveness of mitigation strategies.
Operationalizing variables is a crucial step in research because it allows us to accurately
measure and analyze the variables, we are interested in. For example, if we are investigating the
impact of airplane emissions on the environment, we need to operationalize airplane emissions as
a measurable quantity, such as the mass of pollutants emitted per flight. This ensures that we can
accurately measure the effect of airplane emissions on the environment and compare our findings
with other studies in the field. Overall, operationalizing variables is an essential aspect of
research that helps us to gain meaningful insights into complex phenomena.
Operationalizing the variables can be done in several ways. For instance, to measure
airplane emissions, we could collect data on the mass of carbon dioxide, nitrogen oxides, and
