This document contains a rubric for grading a 3-D cell model project. Students will start with 100 points and lose points for missing or incorrectly labeling organelles, having inaccurate organelle appearances or functions, a sloppy project, submitting it late, or not making the plant or animal cell the proper shape. The rubric lists specific point deductions for deficiencies in 14 organelles and provides space to record total deductions and final grade. Late projects will lose 5 points per day of lateness and any project more than 5 days late will receive a grade of 0.
