LATE PENALTIES FOR LAB REPORTS

10% per week penalty up to two weeks, after which lab reports will not be accepted.

Formal Lab Reports

Theory: This section will typically be ~ 2 pages and will introduce the fundamental concepts and motivation of the lab exercise. Some of this background theory is provided in the lab manual, which you may incorporate in your own words. The theory section will typically involve references from one of more of the course texts. Include chemical structures and/or figures to illustrate, where applicable. (5 marks)

Experimental: Reference the lab manual and note experimental modifications that have been made. Also include specific information about the source and purity of chemical reagents used, make and model of specific instruments employed and operating conditions for instrumental methods. Be sure to describe how duties and responsibilities were divided for labs that involved a group effort. (5 marks)

Data and Observations: Summarize experimental data and observations in tables, wherever possible. Include enough information for the data table to stand alone as a source of information. Be sure to report the source of any data that is not your own. Attach raw data in an appendix. (5 marks)

Results: Summarize results in tables and/or figures (e.g., graphs), where possible. Be sure to include sample calculations (if any) and attach repetitive spreadsheet calculations and graphs in an appendix. (5 marks)

Discussion: Discuss the significance of your results in the context of the theory section. Your discussion should include references to the primary literature so that you can compare your results to those of others. Address any supplemental questions in your discussion section. The discussion section will typically be ~ 2 pages. (5 marks)

Full lab reports are typically about 7-8 pages of text (plus graphics, figures and tables) and will have a cap of 4000 words (no more than 10 pages of text). Each lab report will be marked out of 25 and will be evaluated on organization and presentation as well as content. Be sure to cite all references properly using the ACS style of the journal Environmental Science and Technology.
