Quick description/objective
Materials
Preliminary Questions
Procedure - This does not need to be EVERY single step but it should be enough that I can follow.
Data Table - You can cut out the data table and paste it in. (ONLY do this if your handwriting is neat. Otherwise, type it out.)
Analysis - GRAPHS need to be done on Desmos or similar.
Extensions - Work 1, 2, and 3 (do not actually “try” the lab for #3).
Homework - all homework should be worked on paper and will be turned in on the due date.
