Purpose or Beginning question: What are you hoping to learn or discover by doing the lab?
This section should be completed before the lab.
The beginning question is clear and testable with the proposed procedure.
The beginning question is present but lacks clarity or testability with the proposed procedure.
There is no purpose or beginning question.
Procedure: A brief description of the procedure to be followed is included.
The procedure is written into the lab notebook before the lab. The procedure is a good summary of the procedure to be followed.
Safety: How will you stay safe? What are the precautions you will take? What are the dangerous parts of the lab? This section should be completed before the lab.
Data/Observations: A table for data should be completed before coming to lab. Observations about the chemicals and changes observed during the lab should be listed. What did you observe before, during, and after the reaction/ process?
Data tables are relevant and completed before the lab.
Observations are completed as the lab is being done and are thorough.
The procedure is written into the lab notebook before the lab.
The procedure is a rough description of the procedure to be followed
Data tables are not complete or observations are not thorough.
The procedure is written into the lab notebook before the lab. The procedure is a poor description of the procedure to be followed
Safety considerations are relevant and thorough.
Data tables are not complete and observations are not thorough.
The procedure is not written into the lab notebook before the lab but is completed afterward.
Some important safety considerations are overlooked.
Either data or observations are missing.
Procedure is not in the final lab report.
Safety considerations are absent from the lab.
Data and observations are not present in the final lab report

Calculations/ Results: All calculations should be shown. If the same calculation is done many times it is permissible to do one sample calculation and list the results of subsequent calculations. Watch your significant figures and don’t forget your units. Any graphs should be included in this sections and clearly define the dependent and independent variables.
Particulate representation: Represent the chemical or physical process you are investigating with a picture of what is happening at the scale of individual atoms and molecules.
Sources of Error: Sources of error include systematic and experimental error. They do
NOT include blaming equipment and lab partners. All equipment (and lab partners) are assumed to be functioning optimally for the entire lab. A full statement about the error and its implications for the results should be given.
Answers to Lab Questions: Lab questions from the packet should be answered thoroughly.
Calculations are accurate, error is low, significant figures are correct, and units are correct
*Sources of error are listed, explained and the effect of each error on the results is explained
*Insightfully developed through outstanding critical thinking
All lab questions are answered correctly
Calculations are accurate but error is high. Either significant figures or units are incorrect or missing
Calculations are not done correctly or units and significant figures are incorrect or missing
*Sources of error are listed and explained but some errors do not predict the effect of the error on the results
*Appropriately developed through competent critical thinking
90% of the lab questions are answered correctly
Picture(s) clearly describe what is happening at the particulate level.
75% of the lab questions are answered correctly
Calculations are inaccurate and units and significant figures are incorrect or missing
Calculations section is not included in final lab report
Picture(s) somewhat describe what is happening at the particulate level.
No pictures are included in the lab.
*Sources of error are listed but not explained or do not predict the effect on the results
*Critical thinking skill applied inconsistently
*Sources of error are listed
*
Inappropriate examples or reasons;
insufficient evidence
*Sources of error section is not included in the final lab report
All lab questions are attempted
The answers to the lab questions are not included in the final lab report

Conclusion: The conclusion should be a paragraph or two that discusses the claim you are making, the evidence for that claim and the reasoning relating the evidence to the claim. The words “claim” and” evidence” should be clearly used in the paragraph(s).
*Uses clear and
convincing reasoning, details, text-based evidence, and/or description
*Consistently uses precise language including descriptive words and phrases, sensory details, linking and transitional words to indicate tone, and/or domainspecific vocabulary.
*Uses clear reasoning, details, textbased evidence, and/or description
*Uses mostly precise language, including descriptive words and phrases, sensory details, linking and transitional words, words to indicate tone, and/or domainspecific vocabulary.
*Uses some reasoning, details, text-based evidence, and/or description
*Uses some precise language, including descriptive words and phrases, sensory details, linking and transitional words, words to indicate tone3 and/or domain- specific vocabulary.
*Inadequate reasoning, details, textbased evidence, and/or description
*Limited use of descriptions, sensory details, linking or transitional words, words to indicate tone, or domain-specific vocabulary
*Response is underdevelope d severely
lacking reasons/evidenc e
*Little to no precise language.- fundamental vocabulary mistakes
