Secular homeschool science curricula, compared

5 programs, listed alphabetically, each with its grades, method, format and cost a year as the publisher’s own site showed them on October 29, 2026. Open a card for the strengths, the watch-outs and who it fits.

What this list holds

We label a program secular when the publisher's own pages call it secular, or describe the program and the publisher without any faith terms.

Science curricula range from read-and-narrate books for young children to high school courses with lab work. Many elementary programs cover one topic a year, such as plants or the human body, rather than a little of everything.

This list holds programs sold for science on their own. Full curricula that teach it along with every other subject are on homeschool all-in-one curricula.

At a glance

  • All 5 show a price on the publisher's site. For one child and one year of the main package they run from free to $250, and 1 is free.
  • How the child works: 2 books and workbooks, 1 on screen, 2 video lessons.
  • 1 of the 5 has a placement test or level guide on the publisher's site, linked on each card.
  • Grades: all reach pre-K or kindergarten, all reach the elementary grades, 4 reach middle school and 2 reach high school.
Alphabetical. We never rank programs, and none pays to appear.

Each program in a line

  • Blossom and Root: A family that wants a gentle, hands-on year built around nature, books and art, and is happy to choose its own math.
  • Generation Genius: A family that wants ready-made, video-led science or math lessons with hands-on activities for the elementary and middle school years.
  • Khan Academy: A family that wants free, self-paced practice in math and other core subjects, with a parent who is happy to choose the courses and check progress on a dashboard.
  • Mystery Science: A family with children in kindergarten to 5th grade who wants short, ready-made science lessons with a video to start and a hands-on activity to follow.
  • REAL Science Odyssey: A family that wants one science subject a year, read aloud and done together, with hands-on labs already planned out.

Before you buy

That label is the only thing these pages say about religion. If it matters to you, read the publisher's own pages.

Look for what the experiments need: some programs sell a supply kit, others list household items. For high school, check whether a lab course counts toward the credits you plan to give.

Most publishers post samples and a placement test; each card links the placement test where the publisher has one.

How we label

Every fact on a card was read on the publisher's own website on the date shown, and the page it came from is linked. A fact we could not confirm there is left out. Costs are for one child and one year of the main package, as the publisher's page showed them that day; prices and sales change. Method and format are the publisher's own description where it gives one. The only thing we say about religion is one label, secular or faith-based, given by the rule above; where the publisher's pages don't settle it, the card has no label.
