Context for Use

Make sure students have a basic understanding of lithologies in addition to the method of crater counting for dating and interpreting the ages of Martian terrain.

Homework/Lab

Teaching Notes and Tips

  1. Expose students to Crater Counting such that students realize the geologic timescale of Mars and dating of the Mars surface is based upon crater counting.
  2. For Homework 1 make sure students have a basic knowledge of lithology in order to interpret unconformities.
  3. Depending on class size, if possible, make copies of the geologic maps for students to use during In-Class Activity 1. If class sizes are larger than 30, include these maps in a course packet. Overhead projection of the maps may not be sufficient to engage fully in the activity.
  4. Homework 1 can be adapted for an in-class activity as desired.

Assessment

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