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.
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.
Experimental Design Experimental design is a well-constructed test of the stated hypothesis. Experimental design is adequate to test the hypothesis, but leaves some unanswered questions. Experimental design is relevant to the hypothesis, but is not a complete test. Experimental design is not relevant to the hypothesis.
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.
Drawings / Diagrams Clear, accurate diagrams are included and make the experiment easier to understand. Diagrams are labeled neatly and accurately. Diagrams are included and are labeled neatly and accurately. Diagrams are included and are labeled. Needed diagrams are missing OR are missing important labels.
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. Data are not shown OR are inaccurate.
Error Analysis Experimental errors, their possible effects, and ways to reduce errors are discussed. Experimental errors and their possible effects are discussed. Experimental errors are mentioned. There is no discussion of errors.
Conclusion 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.
Participation Used time well in lab and focused attention on the experiment. Used time pretty well. Stayed focused on the experiment most of the time. Did the lab but did not appear very interested. Focus was lost on several occasions. Participation was minimal OR student was hostile about participating.
