Aim: How to keep a research notebook

A Lab Notebook Is… Complete record of procedures, reagents, data, and thoughts to pass on to other researchers Explanation of why experiments were initiated, how they were performed, and the results

A Lab Notebook Is Not… A journal A record of communications A place to compile lab protocols/manuals Yours to take home

What goes inside your lab notebook… Your Name Table of Contents Main text of notebook (experimental records)

Table of Contents Table of contents helps you and others quickly find previous experiments Write down date, title of experiment, and pages

Experimental Records Date Title: One phrase describing today’s objective(s) Ex- Overview of course and laboratory rules What you did and how you did it Include materials used, along with measurements and calculations Be DETAILED! Note every step. Data (if applicable) Observations, thoughts, questions, etc. Summary: One or two sentences that summarize the day’s events Ex- Describe breakthroughs in your experiment; describe errors you committed; describe what you plan to do tomorrow based on today’s work Last thing: Initial bottom of every page

Additional Documents All letters, sketches, photos, charts, computer printouts, etc. pertinent to the project should be permanently put in the notebook with your initials and date.

General Notebook Housekeeping Use an ink pen to write in notebook Write as you go: the likelihood of remembering a procedure decreases as time elapses There should be no unmarked blank space. Either make a recognizable partition between days (ex-double squiggly line), or Draw diagonal line from corner to corner of blank space. Begin new entries on new page Draw a single line through errors; never use white-out

Lab Ethics All data go in to the notebook Even "bad" data points or “outliers” Failed experiments or contradictory experiments Do not remove pages or mistakes Record facts, not opinions Be honest!
