Writing Lab Reports and Scientific Papers Writing Lab Reports and Scientific Papers by Warren D. DolphinIowa State UniversityVerbal communication is temporal and easily forgotten, but written reports exist for long periods and yield long-term benefits for the author and others.Scientific research is a group activity. Individual scientists perform experiments to test hypotheses about biological phenomena. After experiments are completed and duplicated, researchers attempt to persuade others to accept or reject their hypotheses by presenting the data and their interpretations.

If the results stand up to criticism, they become part of the accepted body of scientific knowledge unless later disproved.In some cases, a report may not be persuasive in nature Tips on Writing Lab ReportsSomeTips on Writing Lab ReportsWritten by Wun Chiou(AFormer UCLA First-Year Lab Courses Teaching Assistant)Alab report is more than just something you turn in to (hopefully) get a goodgrade.

Because the ideal gas was in a closed container, its volume remained constant.

The objective of the experiment is to test whether the ideal equation of state holds. In Laboratory reports are written for several reasons. One reason is to communicate the laboratory work to management. In such situations, management often bases company decisions on the results of the report.

Lab reports are the most frequent kind of document written in engineering and can count for as much as 25% of a course yet little time or attention is devoted to how to write them well.

Worse yet, each professor wants something a little different. Regardless of variations, however, the goal of lab reports remains the same: document your findings and communicate their significance.
