Lafayette College
Geology 115: Earth’s Climate:
Past, Present and Future
• An introductory lab science course that partially
satisfies a science distribution requirement. (~50
students; Lecture 3x/ week, 50min; Lab 1/week, 2 hr 50min, 3
sections)
• Course Objectives:
– Gain knowledge about and understanding of the Earth, its
processes, climate and evolution through time
– Learn to collect/ analyze/ synthesize/ and evaluate scientific
information and apply the knowledge you have gained to new
situations
– Be able to effectively communicate what you have learned
– Enjoy learning the material in this course
Lab#9 A Hollywood Depiction of Abrupt Climate

Lab#9 A Hollywood Depiction of Abrupt Climate
Change – “The Day After Tomorrow”
Objective:
• Allow students to use new expertise to critically evaluate the
scientific validity of the climate concepts and events shown in
the movie: “The Day After Tomorrow.”
Motivations:
• Allow students to apply new scientific understanding to a new
situation.
• Help students think more critically about how science is
presented in popular culture.
• Improve students’ skills in communicating what they have
learned.
Prelude:
• Several in-class lectures on abrupt climate change. Textbook
reading as well as short articles.
In-Lab Assignment
•
Introduction - provide handout; ask them to pay specific
attention to:
–
the following topics:
1)
2)
3)
4)
–
•
any errors as well as valid representations of scientific concepts

What I’ve Found
Kump,
Kasting &
Crane, 2004
• Most are able to solidly critique the depiction of thermohaline
circulation in the movie: both the accuracy of the mechanism
as well as rates of change.
• Struggle with evaluating the storm and the “events” which are
primarily related to weather.
• Good teachable moment about the difference between
climate and weather.

Lab#11 “An Inconvenient Truth”
Final Lab of the Semester
• Prelude: all previous climate related course materials.
(This is a capstone lab).
• Objective:
• Allow students to use new expertise to critically
evaluate the scientific validity of the climate
concepts presented in: “An Inconvenient Truth.”
• Motivations:
• Allow students to apply scientific understanding/
skills acquired in this course to a new situation.
• Help students recognize that what they have learned
is directly relevant to understanding a major modern
day environmental problem.
In-Class Activities
