Prepare Lab Notebook

 

 

 

 

 

 

 

 

Write in Ink

Leave 2 pages for Table of Contents

Begin new experiment on a new page (edit table of contents)

Title and Date top of page

*Write chemical equation on first page

*Include molecular weights, amount of material needed, melting points, etc. in a table

 

Summarize procedure

 

Complete sentences not required!

 

Prepare tables etc. for Data and Observations

 

You will work from this procedure

 

Lab Manuals will NOT be used once experiment begins

 

(* - only for reaction experiments)
