Abstract	Abstract contains a one or two-paragraph concise summary of the entire investigation and includes a quick glimpse of the results.	Abstract contains a one or two-paragraph  summary of the  investigation.	Abstract contains a   summary of the  investigation but is somewhat poorly written.	Abstract was not included or was very poorly written.
Introduction	All relevant background information is included and explained accurately.  The overall question and hypothesis have both been clearly stated here.	Most of the background info is included and explained well.  The purpose of the lab or the question to be answered during the lab is identified, but is stated in a somewhat unclear manner.  Hypothesis is stated and is relevant.	Much of the background info is missing or inaccurate.  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.  Hypothesis is stated	Background info is completely off-base OR not included.  The purpose of the lab or the question to be answered during the lab is erroneous or irrelevant.  Hypothesis is missing or not relevant.
Materials	All materials and setup used in the experiment are clearly and accurately described in specific detail.	Almost all materials and the setup used in the experiment are clearly and accurately described.	Most of the materials and the setup used in the experiment are accurately described.	Many materials are described inaccurately OR are not described at all.
Procedures	Procedures are listed in clear steps. Each step is numbered and is a complete sentence.	Procedures are listed in a logical order, but steps are not numbered and/or are not in complete sentences.	Procedures are listed but are not in a logical order or are difficult to follow.	Procedures do not accurately list the steps of the experiment.
Data	Professional looking and accurate representation of the data in tables and/or graphs. Graphs and tables are labeled and titled.	Accurate representation of the data in tables and/or graphs. Graphs and tables are labeled and titled.	Accurate representation of the data in written form, but no graphs or tables are presented or vise versa.	Data are not shown OR are inaccurate.
Analysis (detailed in the 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.	The relationship between the variables is discussed and trends/patterns logically analyzed.	The relationship between the variables is discussed but no patterns, trends or predictions are made based on the data.	The relationship between the variables is not discussed.
Conclusion (detailed in the Discussion)	Conclusion includes whether the findings supported the hypothesis, possible sources of error, and what was learned from the experiment.	Conclusion includes whether the findings supported the hypothesis and what was learned from the experiment.	Conclusion includes what was learned from the experiment.	No conclusion was included in the report OR shows little effort and reflection.
Experimental Hypothesis	Hypothesized relationship between the variables and the predicted results is clear and reasonable based on what has been studied.	Hypothesized relationship between the variables and the predicted results is reasonable based on general knowledge and observations.	Hypothesized relationship between the variables and the predicted results has been stated, but appears to be based on flawed logic.	No hypothesis has been stated.
Appearance/Organization	Lab report is typed and uses headings and subheadings to visually organize the material.  Followed all formating guidelines and did not use any personal pronouns such as "we, me, my, us, I, etc.".	Lab report is  typed and uses headings and subheadings to visually organize the material. Some formating errors or some use of "I, me, we, etc.".	Lab report is neatly written or typed, but formatting does not help visually organize the material.  Formating is inconsistent and uses too many pronouns.	Lab report is handwritten and looks sloppy with cross-outs, multiple erasures and/or tears and creases.  Poor formatting and an overuse of pronouns.
Drawings/Diagrams	Clear, accurate diagrams are included when appropriate and make the experiment easier to understand. Diagrams are labeled neatly and accurately.	Diagrams are included when appropriate and are labeled neatly and accurately.	Diagrams are included when appropriate and are labeled.	Needed diagrams are missing OR are missing important labels.
