For Physics 128 you will need to purchase two items,
a lab notebook and the textbook.

The lab notebook should be bound, with numbered pages
having a grid.  You will turn in photos or scans of
the notebook pages.  I suggest at least 100 pages.
Here is an example:

The textbook for Physics 128 is

   An Introduction to Error Analysis:
      The Study of Uncertainties in Physical Measurements
   ISBN 1940380081 (978-1940380087)
   3rd Edition
   By John R. Taylor
   https://www.amazon.com/dp/1940380081/

This is an excellent book to learn from, and it does a good job
covering the basics.
