Pre-activity assessment: Use student responses on Student Worksheet
for Step 1: When an Extraterrestrial Object Hits the Earth to learn
what ideas students already have about how impact events have shaped
the Earth.
Post-activity assessment: Use Student Learning Assessment for Step
6: Questions You Would Ask on a Field Expedition to a Possible Impact
Crater
A rubric for scoring the worksheets appears
at the end of this activity.
Comparing pre-activity and post-activity student responses to the
worksheets for Steps 2 and 6 should provide a picture of what students
have learned.
