Vast Deserts on Mars

Summary

Using a Sandbox experiment and Google Earth students will study the formation of dunes and relate their observations to Mars dune field imagery.

Learning Goals

Students will be able to:
  • Identify wind current directions on Earth and Mars.
  • Explain the formation of certain dune morphologies.
  • Use Google Earth to identify changing paleocurrent direction, bounding surfaces, and their potential to be observed/preserved on Mars.

Context for Use

This learning module is meant for adaptation in an introductory earth science course and/or planetary science course.  The In-Class Activities can be easily adapted for homework when desired.

Teaching Notes and Tips

  • For larger classes (>20 students) you can either create your own Sandbox Dune demonstration or use the Video demonstration (see Resources).
  • In Homework 1: students will need a clear understanding of how dunes and dune processes are recorded in the rock record (marching away from you, toward you, paleocurrent direction etc.).
  • You will often integrate the Explain and Explore sections of the In-Class Activities. Interact with the students as they "explore" and help them define terms/principles (Ex: Sandbox Dunes).

Assessment

Methods of assessment are within each individual In-Class Activity and Homework.
