Title of Experiment

I. Introduction

Describe the overall goal(s) of the experiment. What is it that you are trying to accomplish/determine with the experiment?This is often called the purpose of the experiment.

Briefly summarize any relevant background information about the experiment and/or describe the theoretical principles on which the procedure is based, including all relevant chemical equations and/or algebraic equations.

Usually the introductory section takes up about half of a page to one full page.

II. Materials and Methods

The ?Materials and Methods? section tells how the work was done. There should be enough detail that a competent student could repeat the experiment. An outline or flow chart of the procedure is appropriate.If requested by your instructor, clearly, but briefly, describe in a step-by-step fashion the procedure used for the experiment. Excessive detail is not required, however another student should be able to perform the experiment from your procedure.

Sometimes you may be asked to simply cut and paste with a glue stick (do not use staples since they are too bulky and do not hold well.) the procedure into your notebook.In these cases it is important that you read the procedure carefully before entering the lab.

III. Results 

Record neatly and directly into a ruled data table (i.e. made with a ruler!!) all pertinent measurements that are made during the lab period.

If a data table is provided with the lab handout, simply cut and paste it with a "glue stick" into your lab notebook. Do not use a stapler, as staples are too bulky and do not hold well.

If a data table is not included with the lab handout, use a ruler to construct a data table in your lab notebook so that all data is shown in an easy to read table. Pay attention to units and significant figures.

Do not attempt to discuss the interpretation of your data---this should be done in the ?Analysis of Results? section.

IV. Analysis of Results

Include in this section all Calculations, analysis and discussion of your results.

Show all calculations clearly, and with attention to significant figures and units for those experiments that involve calculations. Explain clearly what you are calculating...Don?t leave it to the reader to figure out what is being calculated!!Examples of each calculation should be provided corresponding to the table that depicts that result.You need only show one sample calculation if that calculation is used repeatedly in the analysis of the data.

If there are questions assigned with the lab activity, answer them clearly, but concisely with full sentences.Number your answers as the questions are numbered and make it clear to anyone what the question is that you are answering.

If not addressed in the assigned questions with the lab experiment, analyze your results fully. A full analysis of the results?.

-States what conclusions can be drawn from the results and explains how you arrived at these conclusions,

-Uses specific numerical data and/or observations gathered in the experiment to support all conclusions made,

-Will attempt to explain why results might be inconsistent with the predictions you made (what you thought would happen before you did your study, based on a specific hypothesis or other background information),

-Addresses the major sources of error and explains how these errors affect the results,

-Addresses problems that arose in your study and how could they be avoided in the future,

-Explains what you may have done, if anything, to improve the experiment,

-Compares your results with those of other workers and cites the references used for comparisons,

-Explains any exceptional aspects of your data or unexpected results,

-Examines your results for possible errors or bias, and

-Recommends further work that could augment the results of the study you have presented.
