Lab Reporting Guidelines

LNB

LNB Heaven

This page is designed to provide an overview of what is expected in each section of a lab. Sometimes a lab report is typed while most of the time it is directly written into the LNB. regardless of the final form, the same expectations are used. This page contains the complete list of evaluative parts to the rubric used when grading lab work. Please familiarize yourself with this as I will use it every time. Sample Lab Report [GDrive Link]
