Homeschooling: Free High School Astronomy Curriculum

Thank you for visiting our astronomy curriculum page!  

PLEASE NOTE (3/2020): This resource is being updated: I'm checking links and adding any other material that is helpful. 
All links and subtitles in TEAL are those that have been updated thus far. 

If you don't want your student using just Wikipedia for their research than this curriculum is for you!

When the Oldest was a senior in high school, he chose to complete Astronomy for his last science class. We found a University of Texas Astronomy book quite inexpensively, and I did some of my own research online for things to help aid in his study. The result is this syllabus - and we didn't even really need the textbook! I felt it was important to share it with others who also appreciate saving money in their homeschool budget.  

To get a feel for what a usual high school astronomy class covered, I put together a topical outline that I adapted and revised from Texas Education requirements. As my son completed the course, he marked off the topics on the outline that he has read about, researched and studied. The course outline posted below can be followed to do searches for online reading and study along with the links provided.

Whenever I give a link to a worksheet or quiz, that resource is always free, although you may need to sign up for a free account to access it.  (New additions as of 9/15/2016: worksheet/quizzes added from under various topics.)

While there are videos sprinkled throughout the outline, it is easy to supplement any subject with a video from YouTube.

There are biblical and secular resources in this outline, so I would recommend that you review material before use.  Please message me if there are any links that are not working.

If you have found this page helpful, please bookmark, subscribe to this blog for updates and pin the graphic above on Pinterest to share with other homeschool parents. However, please have any links refer back to this original post. 

There are a couple affiliate links, and if you decide to purchase something in that way, Thank You!

Astronomy and the Bible

One resource I highly recommend is the monthly magazine, "Acts and Facts" from the Institute of Creation Research.  Subscriptions are free and you can sign up on their subscription page.
