LAB REPORT GUIDELINES

Once you have completed your research, you will need to prepare an investigation report that consists of three sections that provide answers to the following questions:

Section 1: Introduction and Guiding Question
What question were you trying to answer and why? (Hint: For the "why," refer to the introduction of your lab. This will help you to determine the background information necessary to answer your guiding question. In other words, why is the guiding question important to your understanding of chemistry?)

Section 2: Method
What did you do during your investigation and why did you conduct your investigation in this way?

Section 3: Argument
What is your argument?

NOTE: Please refer to your rubric for how each section and the overall paper will be assessed.

Formatting Guidelines:

• When titling your paper, please put the following in the header of every page, aligned to the right: Your Name and GEN CHEM 806-134. Then begin your paper with our lab title, centered. FYI, all lab titles are listed and hyper linked to their directions below.

• Your report should answer the three questions listed above in two pages or less.
• The report must be typed and any diagrams, figures, or tables should be embedded into the document.
  • NOTE: The degree symbol in Google doc is under: choose the "Insert" menu, choose "Special Characters," then choose the "Symbol" drop down menu and "Miscellaneous" drop down menu. The degree symbol is at the top of the symbol screen.
• In the way of paragraph spacing, please use 1.5 rather than single or double. Also, please indent the first line of each paragraph 0.5 inches.
• Be sure to write in a persuasive style; you are trying to convince others that your claim is acceptable or valid!

When asked to share your report with me, abiding by the due date is critical. To be sure that your report shared properly, I will respond to the Google share email that is automatically sent to me.
