The lab report is based on the cource material you will just need to read the abstract experimental procedure and re write in your own words (no parphrazing) and the data will be provided as well and you will just need to write a simple lab report with following format:
the attached lab is what will be needed to write however what is written here is just an example on the format
All reports should include the following:
• Title page
• Abstract
• Experimental Procedure
• Results
• Discussion
• Conclusion & Referecnes
• Calculations & In-Lab Printouts (as needed)
Everything should be typed. This includes chemical formulas and calculations.
Make sure to use the correct super- and subscriipts.
Use the passive voice. For example:
Correct: “The temperature increased as the mass increased.”
Incorrect: “The temperature increases as the mass decreases.”
Do not use “I” or “we.” For example:
Correct: “Using a stir plate, the chemicals were mixed.”
Incorrect: “We used a stir plate to mix the chemicals.”
Do not use contractions. For example:
Correct: “The precipitate could not be filtered.”
Incorrect: “The precipitate couldn’t be filtered.”
Do not reference yourself. Do not mention “the students” or “during the lab period.”
Abstract
The abstract is a shortened version of the paper and should contain all
information necessary for the reader to determine the following:
• What the objectives of the study were;
• How the study was done; (briefly, not in detail… do not mention
glassware, etc.)
• What results were obtained;
• What is the “real world” significance of the results?
By reading only the abstract, the reader should understand all of the above. Although
it appears as the first section in a paper, it is best to write the abstract last. Abstracts
should be only one paragraph, no more than a half-page long. To most effectively
write an abstract, include the four points above in that order.
Experimental Procedure
This is where you detail the exact procedure of the experiment. This is not a step-by-
step instructional guide. Summarize your procedure in passive voice and ensure that it
is in a paragraph form not bullet points. Include the important details, you do not need
to go into the details of specific techniques as it is assumed that your reader already
has a background in chemistry.
Results
This should be several short paragraphs describing the results obtained from your
experiment. You should use tables and/or figures to help guide your readers toward
the most important information you gathered. You will need to refer to each table or
figure directly, for example, “Table 1 lists the rates of solubility for each substance,”
or “Solubility increased as the temperature of the solution increased (see Figure 1).”
If you do use tables or figures, make sure that you do not present the same material in
both the text and the tables/figures. Any tables or figures used should not show the
collected data from the experiment, only the results determined. The results of any
calculations performed should be shown in the Results section; either in the text, or in
a table.
Describe any trends that emerge as you examine the data. For example, “Heating the
solution increased the rate of solubility of polar solids by 45%, but had no effect on
the rate of solubility in solutions containing non-polar solids.”
Discussion
Discuss any observations you recorded during the experiment to share with the reader.
List any errors or deviations that occurred during the experiment, and how they may
affect the final results.
Always refer to your results in the past tense, because the events you recorded have
already occurred. In the example above, note the use of “increased” and “had,” rather
than “increases” and “has.” You do not know from your experiment that heating
always increases the solubility of polar solids.
Conclusion
The conclusion should wrap up your report and mention how successfully your
objective was satisfied. Reiterate your main results and propose improvements to the
procedure that can help overcome the limitations of your work. This does not need to
be long.
Calculations & In-Lab Printouts
Present one sample for each type of calculation you did throughout the
experiment. Separate your calculations by parts of the experiment. Always include
units throughout the calculations. Show all numbers used in the calculation, saving
the significant figure rules for the final result. Always follow a numerical result with
an identifier. For example:
Part A: Molarity of the solvent
Molarity = moles/L
Molarity(NaOH) = 0.50 mol NaOH / 2.0010 L
Molarity(NaOH) = 0.2498 M ≈ 0.25 M NaOH
The resultant number has no meaning without the units (M) or the identifier (NaOH).
Referecnes
In-text citations are a must! You cannot claim that “extraction is used in the XYZ
industry” and have no reference to substantiate your claim. Your reader should be
able to verify the validity of your statements. Also, your references cannot be copy-
pasted links to websites. Use proper ACS referencing formatting. You can use this
website for your citations:
All work must be your own. You and your lab partner may be sharing data, but
should be writing down your own results and observations. You may work
together in performing the calculations and determining the results. But your
report must be your own work! Copying a report, either whole or in parts, is
considered a violation of the Aggie Code of Honor and any findings will be
reported to the Academic Affairs office.
I added screen shots of whatever you need and the excel sheets for the data
