This document provides a grading rubric for lab reports with criteria in 5 areas: introduction, methods, results, discussion/conclusion, and writing mechanics. Each criterion is scored on a scale of 0 to 20, with higher scores indicating more complete and accurate components that clearly communicate the experimental process and outcomes. The rubric provides descriptions of the qualities expected for basic (C-range), proficient (B-range), and exemplary (A-range) performance in each area.
