Who this lab notebook is for

This lab notebook is for high school and college students, homeschoolers taking lab sciences, and hobby scientists who want clear, dated records. It also helps tutors and science teachers who model good lab practice. If your notes are scattered across loose paper, it gives every experiment a proper home, from the first question to the final result.

How to use your lab notebook

Number each experiment and add it to the contents index so you can find it later. On the experiment entry page, write the date, aim, method and any changes you made. Record raw numbers in the data tables and plot them on the graph paper pages. Summarize what happened on the results page and write a short conclusion. Keep the reagent log and equipment log up to date so you always know what was used, when and how much.
