Course materials


No textbooks required

Open educational resources (OER)

The following free or inexpensive materials are used for this course:


1. Some of the labs will require you to plot data and make drawings. Most labs will be provided as Google Doc files. You have a few options on how to work with and submit these files. Three potential options are:

  • Work directly in Google Docs and export to a PDF,
  • Export the Google Doc into a Word or PDF document and complete in one of those programs,
  • Print out the labs, complete them by hand, and scan them into a PDF file.
    If you do not have a scanner, it's often possible to use a smartphone and free apps or software to convert photos of hand-written labs into PDFs.

Either way, you need to be comfortable editing digital documents, making freehand drawings, and writing equations for submission as a PDF or MS Word file. 

2. You should know how to take a screenshot
