CesiumChemistry 1121/1223 Lab Report Format

Following is the format for the informal and formal lab reports. Please note the following:

• The report should be typed (12 pt font, Times New Roman, double spaced) on
8 ½ x 11 paper.
• Equations and calculations may be hand written.
• Present all sections in the order given.
• The lab report is about the work you did; therefore, the discussion and

conclusions must be based on results obtained in the lab.
• (Academic Misconduct) Copying, manipulation/fabrication of data, plagiarism,

content similarities etc. will not be tolerated and will be heavily penalized. There
will be no distinction between those who copy and those who let others copy
them.

• Any changes to these guidelines will be announced.
• Important: Make a backup copy of your lab before handing it in.

Format for an Informal Report

1: Title Page
2: Introduction – Purpose and relevant equations (chemical and mathematical)
3: Experimental Method
4: Results
5 : Conclusions
6 : Questions
7 : References

Format for a Formal Report

1 : Title Page

2 : Abstract

3: Introduction – Background and Purpose

4: Materials and Method

5: Results

6: Discussion

7: Conclusion

8: Questions

9: References

Title Page
Your title page should include all of the following:

• Title of the report
• Your name
• Name(s) of your lab partner(s)
• Your instructor’s name
• Course name (including section number)
• Date of the lab and date that the lab is due.
• Location at which the lab took place

The title page should be typed (minimum 12 font). Use the entire page and ensure that
it is readable and interesting. Optional: If you have suitable graphics that can be
incorporated, please do so.

Abstract

In one paragraph, state the purpose of the lab and the major findings. Your abstract
should be concise, yet complete; it should provide an overview of your scientific
investigation. By reading the abstract, your reader should have a general idea regarding
the nature of the work, the main experimental findings and the relevance of these finding
to the scientific literature. In general, your abstract should be one paragraph and no
more than 250 words; it should stand-alone. Avoid references in the abstract.

When writing the abstract, you should consider the following:

• Why was the study performed?
• What was the purpose of the experiment?
• What basic methods were used?
• What results were obtained?
• What were the major findings?

Hint: People often find it easier to write the abstract last after the entire report is
completed.

Introduction – Background and Purpose

The Introduction is presented in paragraph form. The intention of the introduction is to
“introduce” the topic of the paper. For the formal report it should provide a brief overview
of the literature (background) such that the reader can evaluate and understand the
rational for
