Introduction: This section should cover the chemistry concept(s)/theory involved in the experiment. Explain what this experiment is about and how the goal of the experiment will be accomplished. The introduction should not be lab procedure. Use your own words but please use your textbook as a resource in understanding and explaining the principles underlying the lab.

Procedure: This section should be a general procedure that you followed to complete the lab.  There is NO need to go into great detail, but you need to report enough detail that a reader understands how you completed the lab.  Make sure that you include what web resources that you will use for the lab.

Note: All the above sections of an experimental report should be prepared in advance.

Data/Observations:  As part of your pre-lab you are required to prepare any data tables you need for the experiment in advance. For most of these labs, you will record your all primary data, such weighing measurements, volume measurements, observations of chemical reactions, and the like which will be recorded as you perform the experiment. Whenever it is possible, record data and observations in a table format. It is bad laboratory practice to record primary data on paper towels, napkins, or scratch paper. It is very important to write the data and observations accurately and neatly in your lab notebook. This is precisely why we are haivng you prepare the data tables you need for the experiment in advance so that you can record the data in lab early.
