Lab Report Assistant

This document is not meant to be a substitute for a formal laboratory report. The Lab Report

Assistant is simply a summary of the experiment’questions, diagrams if needed, and data

s

tables that should be addressed in a formal lab report. The intent is to facilitate students’

writing of lab reports by providing this information in an editable file which can be sent to an

instructor.
