Each student's work should be
scored holistically as follows
Strong Indication of Competence:
The student's work is complete with thoughtful answers to questions. Work
clearly indicates that student understands the process of determining planetary
rotation and can determine the reasonableness of results.
Weak Indication of Competence:
The student's work is complete but there is little obvious work beyond
the required "fill in the blanks." Student does not use complete sentences
or work suggests that it has been done by teammates. Student understands
the concept of rotation but not how it is calculated
No Indication of Competence:
The student's work is incomplete suggesting that little effort was
made to use the pictures available to determine rotation rates.
