Description of the activity/assignment

Students are taught how to use FossilPlot software in the lab prior to this exercise. Students work individual to work through the short exercise, handing in a copy of the diversity graphs for the brachiopod orders (which will be tested in the following midterm) and a completed worksheet. The exercise reinforces the main functions of FossilPlot and addresses basic concepts on diversity and biostratigraphy. Once the assignments are collected and graded, we discuss the outcomes of the exercise in class.

Determining whether students have met the goals

Answers to the questions on the worksheet are 'right or wrong' based on if the student followed correct procedure in answering the question. The final open question (on biostratigraphy vs radiometric dating) is used as a gateway question to be expanded in the following lab.
