GEOLogic questions are puzzles that were developed to support students understanding of geoscience concepts while challenging them to develop better logic and problem solving skills.
In this example, students are asked to match up several unique fossils with the sites and locations where they were found, as well as their geologic age.

Learning Goals

Context for Use

This activity is appropriate for a high school science class or an introductory level undergraduate geoscience course. The activity can be given as an in class assignment or for homework.

Teaching Notes and Tips

As long as the student makes a substantial effort towards solving the problem, they receive credit for the assignment. Alternatively, GEOLogic problems could be used as extra credit exercises which would be graded more rigorously.
