Laboratory Report Guidelines

 

These guidelines pertain mainly to the reports for the assigned laboratories.

General Guidelines

Formatting

Organization

Title Page (does not count toward page limit). The title page should contain the lab number, the lab title, your names, your section, the date, and the names of your lab partners.

Introduction (about one-half page). The introduction should contain a brief statement of (1) the purpose of the lab, (2) the environmental importance of the parameters being measured, and (3) if applicable, a hypothesis about the outcome of the lab.

Materials and Methods (about one-half to one page). The Materials and Methods section should provide a description of key steps taken in the lab.  The steps should be described in past tense (not as instructions in present tense).  Avoid narration, which is often marked by words like "first," "next," "after," and "then."  A sketch of the experimental apparatus should be included as a figure.  A description and map (figure) of the site from which the samples were obtained should be included. 

Results (about one-two pages). This section should include the results presented primarily in tables and graphs. If you said you did something in the Materials and Methods, show the results. Also, show the results of any calculations (including equations if necessary) and statistical analyses you performed.  For equations, show the general equation with variables, but do not show any step-by-step insertion of values or rearrangements to find the solution.  List the equation variables in the text and values used for the variables in the text or a table.

Discussion (about one-two pages). What do the results mean? Have your experiments tested your hypotheses (if you had any)? What problems were encountered? This is the section where you can show that you understood not only how to follow a recipe, but that you understood why you were doing the lab. Each lab will have a short set of questions that will give you a good idea of the material that should be covered in the Discussion. You should answer these questions by integrating the answers into your written discussion, not by simply answering the questions with numbered responses.

Lab Evaluation (optional; just some feedback; does not count toward page limit). Was the lab well set up? Did you learn something about the techniques? Did you learn something about the chemistry? Was this too much work? I will try to use these comments to improve labs later this semester and in following years.
