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?
