Question/Purpose
|
The purpose of the lab or the question to be answered during the lab is clearly identified and stated.
|
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.

|
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.
|
|
Safety
|
Lab is carried out with full attention to relevant safety procedures. The set-up, experiment, and tear-down posed no safety threat to any individual.
|
Lab is generally carried out with attention to relevant safety procedures. The set-up, experiment, and tear-down posed no safety threat to any individual, but one safety procedure needs to be reviewed.
|
Lab is carried out with some attention to relevant safety procedures. The set-up, experiment, and tear-down posed no safety threat to any individual, but several safety procedures need to be reviewed.
|
Safety procedures were ignored and/or some aspect of the experiment posed a threat to the safety of the student or others.

|
Conclusion
|
Conclusion includes whether the findings supported the hypothesis, possible sources of error, 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.

|
Analysis
|
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.
