  Poor

1 pts

Fair

2 pts

Good

3 pts

Purpose
3 pts

Poor

Purpose missing or incomplete. Purspose is not clear or does not represent the full intended purpose of the lab. No chemical reactions present where appropriate
Fair

Copies the words from the text. Does not elaborate on possible outcomes. Chemical reactions are present where appropriate,but not complete.
Good

Clearly defined purpose. Good use of sentance structure. Defines intended outcomes of the lab. Chemical reactions are presented where appropriate
Data
3 pts

Poor

Data not labeled. Units missing. It is not clear what each piece of data represents. Significant figures not used.
Fair

Data is labeled but some units are missing. It is generally clear what each peice of data represents but assumptions must be made to do so. Significant figures used in some but not all measurements.
Good

Data is well labeled and presented in a logical manner (data table if necessary). The measurments have units and it is clear what each piece of data represents. Significant figures used in all measurments.
Results
3 pts

Poor

Calculations missing. Units not used. Significant figures not used.
Fair

Calculations present but units not used throughout. Calculations are not well labeled. Significant figures not used in calculations
Good

Calculations are neatly presented and are clearly labeled. Units are used throughout calculations.
Technique
3 pts

Poor

Melting points missing or extremley far from the accepted value. FTIR missing or does not show appropriate peaks. GC shows high levels of impurity. Yeild is extremely low or non-existent.
Fair

Melting points are broad or not near the accepted value. FTIR shows appropriate peaks but has a large amount of noise or not enough sample. GC shows large amounts of Impurity. Yeild is low or over 100%.
Good

Melting points are near accepted values and have a narrow range. FTIR shows appropriate bond peaks. GC shows a reasonable level of purity. Yeild is sufficient for the reaction.
Conclusions
3 pts

Poor

Conclusions are not supported by the data. Conclusions do not support the accomplishment of the purpose of the lab.
Fair

Conclusions are appropriate to the data but the data is not used to explicitly support the conclusions.
Good

Conclusions are supported by the data and reference the purpose of the lab. FTIR data is used to support presence of synthesized material. GC data is used to support the total amount of "pure" material generated.
Discussion of Error
3 pts

Poor

Discussion of error missing or incomplete. Student blames their results on their own mistakes and lack of time to do the lab.
Fair

Student lists possible ideas for error but does not provide info about how they would affect the results. Student uses "human error" and "spilling" as sources of error.
Good

Student discusses possible errors and how those errors may have directly affected the outcomes of the experiment. How would it be different as a result
Questions
3 pts

Poor

Questions missing or incomplete. Many incorrect answers.
Fair

Completed but some incorrect answers. Explanations are not thorough enough to show understanding of the material
Good

Completed and correct
Overall Report
3 pts

Poor

The report does not flow logically. Parts are missing. Handwriting is illegible.
Fair

The report is written with a logical flow but parts are incomplete
Good

Report is written neatly and is presented in a logical format. writing mistakes are crossed off with a single line and corrections written nearby.
