A lab assignment for a geology course that allows students to critically evaluate the scientific accuracy of climate concepts presented in the movies "The Day After Tomorrow" and "An Inconvenient Truth". Students summarize and analyze the strengths and weaknesses of the movies in a short paper.

Student Critiques of “The Day After Tomorrow” and “An Inconvenient Truth” Kira T. Lawrence 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 Change–“The Day After Tomorrow”
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: • Proposed mechanism for climatic change • Events that signal a change in climate • Characteristics of the storm • Rates of climate change • any errors as well as valid representations of scientific concepts • View movie • students take notes on handout • I serve popcorn and soda • Conclusion of the movie: instructor led discussion
Take Home Assignment • Using their notes from the film as well as the in-lab discussion, student write a short paper summarizing and analyzing the scientific strengths and weaknesses of the movie. • Part 1 summary of the climate concepts and events in the movie. • Part 2 assessment of the accuracy of the science presented.
Evaluation Concisely summarize? • Accuracy of Summary of Movie: • Mechanisms (10) • Storm Characteristics (5) • Climate Events (10) • Rates (5) • Accuracy of Explanation of Reality: • Mechanism (10) • Events (10) • Storm Characteristics (10) • Rates (10) • Writing: • Organization (10) • Clarity (10) • Grammar (10) Apply knowledge? Effectively Communicate?
What I’ve Found • 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. Kump, Kasting & Crane, 2004
Some Other Candidate Movies • Dante’s Peak • Volcano • The Core • Jurassic Park • Evolution • Armageddon • Deep Impact
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 • Introduction: ask them to respond to the following and assess whether or not Al Gore portrays them accurately: • Mechanisms for climatic change/ climate concepts invoked in the movie • Climate records & observations you recognize and what Al Gore says about them • According to Gore, what are the current and potential impacts of climate change? • According to Gore, how has the climate change issue been treated by media / government? • View movie • Instructor led discussion • Students answer questions: • List 3 messages you have taken away from this movie. • List 3 questions you have about climate change after watching this movie. • Do you think climate change is a moral issue? Why or why not?
