PHYSC 110:
Energy and the Environment
This course provides students not majoring in
science with an opportunity to study world
energy and environmental problems while
learning basic concepts of physical science.
What is Physical Science?

The Students
• 87% needed a physical science course to
fulfill their degree requirements.
– focus of study: education, business, fire
science
• 74% took this course because they are
interested in energy/environmental issues.
• 53% agreed with the following statement:
“The thought of taking a science course
scares me.”
• 41% are uncomfortable with math.

Why use a Geoscince Perspective?
• Overlooked aspect of
Physical Science
• Fundamental to the
understanding current
energy and environmental
issues
• Student Interest and
Engagement

Fossil fuel resources are finite and are limited by
geology
The amount of energy resources that humans
can recover is limited by technology which is
limited by natural laws
