The rubric provides grading criteria for an extinction event paper assignment. Students must: 1) Write a 1-1/2 to 2 page paper. 2) Include at least 4-5 of the listed items about the extinction event. 3) Demonstrate good effort and quality of work. The listed items to include are: the time periods, the suspected cause, two extinct animals by name, one environmental result, and what happened after the extinction to get things back on track. Students have one day in the computer lab for research and writing, and the paper is due the following day.
