Resources for Earth Science and Astronomy for the Logic Stage

Spine Texts*

The following books are the main spines of this program. You will need to purchase both of these to complete the reading assignments scheduled in this program. (Note—The editions noted here are the most current editions. However, the past two editions of each of these spines will also work.)
