Purpose
The purpose of a lab report is to present the work completed in a lab test or experiment. This information may be used in several different ways. For instance, a lab report may explain why certain materials reacted the way they did. Or, perhaps someone will use the data from the report to make a decision about which material to use in a design or project. In this case, you may have to argue, based on your results, why a particular material is better than another. When documenting your lab work, always consider how someone will use the information.
