The Individual Laboratory Report Although raw data collected in the laboratory may, of course, be shared amongst group members, the

laboratory report must be the students own, individual work. The laboratory report is not a group

assignment; any plagiarism will result in a zero for the laboratory report score in addition to any other

consequences of academic dishonesty. If you are unsure as to what might constitute plagiarism within

the laboratory report, be sure to ask your TA or instructor before submitting anything.

In general, a scientific paper should:

 Be concise but descriptive

 Use a past tense, third-person narrative and strong verbs

 Be written in paragraph form

 Follow the outline provided below

Individual Laboratory Report Rubric (100 points)

Title (5 points)  5 points. A descriptive title that clearly represents the main experimental question and what

was measured (and was not copied from the Project Description). Report author's name and

group member's name(s) are listed.

 4 points. An adequate title that mostly represents the main experimental question and what

was measured (and was not copied from the Project Description). Report author's name and

group member's name(s) are listed.

 3 points. The title does not make clear what the main experimental question or what was

measured (and was not copied from the Project Description). Report author's name and group

member's names are listed.

 2 points. A generic title such as "Lab Report 1" or copied from the Project Description and/or

incomplete list of names.

 0 points. Not included.

Abstract (10 points) This section outlines the purpose of the experiment, the tests carried out, and the measured values

obtained. Details about errors that occurred, etc. should not be included. This section is essentially a brief

summary and should typically be around only four or five sentences in length.

 10 points. A clear, concise description of the purpose of the experiment, tests carried out, and

measured values obtained. The text is tightly focused and relevant.

 8 points. A decent description of the purpose of the experiment, tests carried out, and

measured values obtained. Text is fairly focused and mostly relevant.

 6 points. A mediocre description that mostly encompasses the purpose of the experiment, tests

carried out, and measured values obtained with significant details omitted. Text is only

somewhat focused.

 4 points. A poor description that mostly encompasses the purpose of the experiment, tests

carried out, and measured values obtained with significant details omitted. Text is poorly

focused.

 0 points. Not included.

Introduction (15 points) The section should state the hypotheses/objectives of the experiments and why these experiments were

carried out. This should include externally referenced information that ties into the preformed

experiment and enhances the reader’s understanding of the topic. This is also where the underlying

theory of the experiments should be described. This section should typically be about one-half to one

page in length at the most.

 15 points. The introduction contains scientific background information from relevant sources to

explain the context of why the study and the variables are important. The research question and

information are translated into student’s own words. Purpose of the experiment, research

question, hypothesis and predicted outcome are clearly stated.

 12 points. The introduction refers to some scientific background information but does not

completely support the research question or variables. Purpose, research question, hypotheses,

and predictions are stated.

 8 points. The introduction does not provide adequate background information about the

question or variables of the research question, and/or research question, hypothesis or

predictions are missing.

 5 points. Little to no background information is provided. The introduction is missing several

pieces of information including purpose, research question, hypotheses and predictions.

 0 points. Not included.

Experimental (10 points) This section should detail what was actually done in the laboratory. It is essentially a well-edited version

of the information collected in the laboratory notebook during the experiments. Calculations are not

included in this section. This section should be in your own words, and should include all pertinent

experimental details.

 10 points. The methods for data collection are clearly described (i.e. someone who has never

done this before could read the methods and easily duplicate them). Methods are written in

past tense, paragraph form and not as a list of steps.

 8 points. A few minor steps are missing but all of the important steps are included. Methods are

written in paragraph form.

 6 points. A few important steps in the methods are missing. Methods are written in paragraph

form.

 4 points. Procedures for data collection are unclear and missing important steps. Methods are

not written in paragraph form.

 0 points. Not included.

Results and Discussion (25 points) This section is typically the largest in the laboratory report and contains the following information. The

Results and Discussion section should not include data irrelevant to the discussion and conclusions

drawn.

 25 points. The results are correctly interpreted and related to the research questions,

hypotheses, and predictions. Hypotheses (both null and alternative) are accepted or rejected

with a clear explanation. The results are compared to previous research cited in the discussion

and discussed in the context of the broader scientific community. Errors in the experiment are

identified and their implications discussed, as are modifications of improvements that should be

made in future research. Sample size and extrapolation of results is discussed. Relevant

additional research questions arising from the result are posed and further studies are

suggested. Clear understanding of the results and experiment is evident

 20 points. Most of the results are correctly interpreted and related to the research questions,

hypotheses, and predictions. Hypotheses are accepted or rejected with at least a minimal

explanation. Results are compared to previous research and within the context of the broader

scientific community. Errors in the experiment are identified, as are modifications or

improvements that should be made in future research. At least one research question arising

from the results is posed and further studies are suggested. Clear understanding of the results

and experiment is evident.

 15 points. Some of the results are correctly interpreted. Results are superficially compared to

previous research. Hypotheses are accepted or rejected but no explanation is provided. Errors in

the experiment or improvements are discussed. Additional research questions and future

students are not relevant. Partial understanding of the results and experiment is evident.

 10 points. Results are incorrectly interpreted or discussion is incomplete. Hypotheses are not

addressed. No errors or modification are identified. No additional research question or future

studies are suggested. There is an overall lack of understanding of the results.

 0 points. Not included.

Conclusions (10 points) This section provides a summary of the experiment and results. It should be more in depth than the

abstract and will typically be about two paragraphs.

 10 points. A clear, concise summary of the experiment and results, with no new experimental

data added. The text is tightly focused and relevant.

 8 points. A decent summary of the experiment, with no new experimental data added. Text is

fairly focused and mostly relevant.

 6 points. A mediocre summary of the experiment that mostly encompasses the purpose of the

experiment, with no new experimental data added. Text is only somewhat focused.

 4 points. A poor summary of the experiment with significant details omitted. Text is poorly

focused.

 0 points. Not included.

References (5 points) This section records the resources used to create the lab report. This should include many more resources

than just the project description, and should be referenced throughout the report in ACS formatting.

 5 points. Each in-text citation is included in the bibliography section and vice versa. In-text

citations are formatted correctly. No direct quotes are used and all work cited is paraphrased

appropriately. Bibliography is formatted correctly and according to ACS standards.

 4 points. Minor errors in formatting but all other requirements are followed. No direct quotes

are used; all work cited is paraphrased appropriately.

 3 points. A few formatting errors in text citations or literature cited. An in-text citation or

citation in the bibliography is missing. No direct quotes are used and all work cited is

paraphrased appropriately.

 2 points. Format and style are inappropriate for the assignment and do not follow ACS

guidelines. Direct quotes are used or work is not paraphrased appropriately.

 0 points. Not included.

Figures and Tables (10 points)  10 points. The figures and tables are correctly displayed. Each figure/table is labeled (e.g. Fig. 1).

Plot axes are correctly labeled and include units. Columns and rows are clearly labeled in tables.

A clear description is given as a caption for the figure or table (i.e. a reader could look only at the

figure/table and understand the data). Figures and tables are computer generated, clear,

organized, and easy to read.

 8 points. The figures and tables are correctly displayed but have minor problems. Minor issues

with formatting but otherwise all formatting requirements are met.

 6 points. Some mistakes with figures and tables. Inappropriate format is used for plots (e.g. line

vs. bar). Important information is missing from captions. Some labels are missing.

 4 points. Figures and tables contain significant errors that lead to incorrect interpretations or

results. Labels are missing and formatting is incorrect and does not follow guidelines.

 0 points. Not included.

Overall Writing Style (10 points)  10 points. Format follows course guidelines. No obvious errors are present in writing and report

was proof read and no obvious errors are present. Writing includes complete sentences, correct
