As a home educating parent of 11 years, I love sharing some of the best homeschool resources that I’ve come across for exploring all kinds of subjects and topics. I previously published a post on homeschool secular curricula for history (find secular history curriculum) and Spanish homeschool curriculum. I also wrote about 100+ homeschool resources. Today’s post is about the best secular homeschool science curriculum!
If you are a homeschool mom or dad looking for some of the best secular homeschool science curriculum for every interest and grade level, keep reading (and bookmark) this post.
Although it seems that a lot of science curriculum is developed by faith-based companies, there are several options available for homeschooling families who would rather take a more secular or neutral standpoint.

What Is Secular Homeschool Science Curriculum?
The word secular has evolved to mean a variety of things, so I think it is important to identify what this means from a scientific point of view. Secular science curriculum should not be based on any one set religion.
Instead, it includes acceptable scientific theories that are not influenced by religious beliefs.
Secular science curriculum also doesn’t teach intelligent design (God), or “new Earth science” which is a set of beliefs that isn’t accepted by today’s scientific community.
Overall, a secular science curriculum seeks to present theoretical content that can be further studied and backed up by factual findings. There are a lot of great options so you can design a complete secular homeschool curriculum for your science exploration.
Why Use a Secular Homeschooling Curriculum for Science?
The reasons to use a science program or curriculum that is separate to religious instruction are many and varied. It is possible to argue that children will get a better education if personal beliefs are kept separate to scientific fact.
This doesn’t stop families of faith (usually Christian homeschoolers but also frequently Muslim or Jewish families) from also bringing up their children in a way that aligns with their beliefs. It simply means that children can benefit from an objective view based on physical science facts (as far as we know them).
It may also be the best choice to avoid religious homeschool curriculum when it comes to science if your children may attend public schools at some point. It means that they will be better aligned with what other children are learning in the core subjects, which is an important factor in adapting when moving out of the homeschool world.
I have rounded up some great science curriculum for secular homeschoolers- these are divided into subscription boxes, books, online classes and curriculum packages.
