SUMMARY
30 minutes required. Summary by CLEAN Reviewers:
These animations depict the three major Milankovitch Cycles that impact global climate, visually demonstrating the definitions of eccentricity, obliquity, and precession, and their ranges of variation and timing on Earth.
GOALS
Goals adapted from CLEAN Reviewer comments:
-
Animations are provided of the three major Milankovitch Cycles that impact global climate, visually demonstrating the definitions of eccentricity, obliquity, and precession
-
Animated visualizations will help students who struggle to understand the concepts of precession, eccentricity, and obliquity

TEACHING NOTES / CONTEXT FOR USE
Teaching Notes / Context for use by CLEAN Reviewers:
Teaching Tips
-
Students struggle to understand these concepts of precession, eccentricity, and obliquity; this animated visualization will help.
-
The quizzes that are included are either very simplistic or problematic to get correct answers to (this is particularly true for the one on obliquity cycles). However, the visualizations, although relatively old, are accurate and well-explained.
About the Science
-
Animations are provided of the three major Milankovitch Cycles that impact global climate, visually demonstrating the definitions of eccentricity, obliquity, and precession.
-
The visual exaggeration of cycles is enormous, but is acknowledged in text on the slides.
-
Comments from expert scientist: The activity is a good review/introduction of the concepts of Milankovitch cycles.
-
The questions posed along with the progression of the activity are a good check for understanding of the material.
-
Educator should define the term "insolation" prior to use.
About the Pedagogy
-
Tests of student knowledge and skills included in the tutorial range from simplistic to frustrating, as correct answers are not identified.
-
Students click through 9 slides, choosing buttons to change states, with occasional self-tests.
Technical Details/Ease of Use
-
Easy to use. Animations, while not to scale, are accurate in their descriptions and get the job done. This should be an improvement over static diagrams for most students.
ASSESSMENT
Assessment is at the discretion of the instructor. There is a quiz at the end of the animation sequences, but note the following teaching tip from a CLEAN Reviewer:
The quizzes that are included are either very simplistic or problematic to get correct answers to (this is particularly true for the one on obliquity cycles).
SHORT DESCRIPTION
Description by activity author: In this tutorial you will learn about eccentricity, obliquity, and precession and how they change through time. You will also learn how these changes may influence the Earth's climate.
