Lab Report Grading Criteria

category	5 (95pts)	4 (85 pts)	3 (75 pts)	2 (65 pts)
Components of the report	All required elements are present and additional elements that add to the report (e.g., thoughtful comments, graphics) have been added.	All required elements are present.	One required element is missing, but additional elements that add to the report (e.g., thoughtful comments, graphics) have been added.	Several required elements are missing.
Introduction/ purpose	The purpose of the lab or the question to be answered during the lab is clearly identified and stated. Background information in included.	The purpose of the lab or the question to be answered during the lab is identified, but is stated in a somewhat unclear manner.	The purpose of the lab or the question to be answered during the lab is partially identified, and is stated in a somewhat unclear manner.	The purpose of the lab or the question to be answered during the lab is erroneous or irrelevant.
Procedure	Procedures are described in clear sentences. All materials and setup used in the experiment are clearly and accurately described. Diagrams/pictures are used to help illustrate procedure.	Procedures are described in a logical order, but sentence structure is weak. Almost all materials and the setup used in the experiment are clearly described.	Procedures are explained, but not in a logical order or are difficult to follow. Most of the materials used in the experiment are mentioned.	Procedures do not accurately describe the steps of the experiment. Many materials are described inaccurately OR are not described at all.
Results	Professional looking and accurate representation of the data in tables and/or graphs. Graphs and tables are labeled and titled. All calculations are shown and the results are correct and labeled appropriately.	Accurate representation of the data in tables and/or graphs. Graphs and tables are labeled and titled. Some calculations are shown and the results are correct and labeled appropriately.	Accurate representation of the data in written form, but no graphs or tables are presented. Some calculations are shown and the results labeled appropriately.	Data are not shown OR are inaccurate. No calculations are shown OR results are inaccurate or mislabeled.
Discussion	The relationship between the variables is discussed and trends/patterns logically analyzed. Predictions are made about what might happen if part of the lab were changed or how the experimental design could be changed. Conclusion includes whether the findings supported the hypothesis and possible sources of error.	The relationship between the variables is discussed and analyzed. Conclusion includes whether the findings supported the hypothesis.	No relationship between the variables is discussed. No patterns, trends or predictions are made based on the data..	A relationship between the variables is not discussed. No conclusion was included in the report OR shows little effort and reflection.
