Every lesson works on screen or printed — same lesson either way, for the days you want them at the table, or when there are more kids than computers.

Cost

Included in your subscription — every grade, every lesson, for every kid on your account.

Nothing extra to buy, and no per-child or per-subject fee.

How it teaches

  • A full K-12 arc: the early grades start with what a child can actually observe — light and shadow, weather, living things — middle school moves into matter, energy, cells and body systems, and high school becomes four named courses
  • Those four — Biology, Chemistry, Physics, and Earth & Space Science — are named separately so they read properly on a transcript
  • Built against the Next Generation Science Standards, which are public and free to check rather than a private scope we invented
  • An interactive periodic table and labelled diagrams the child works with directly, not photographs of somebody else's experiment
Who it fits
Families who want a real high-school science sequence at home without assembling four separate courses

Already bought Science? Bring it with you.

Most families arriving here already own something. You do not have to throw it away to use Homeschool Factory, and you do not have to choose between it and ours. Tell us the Science book you have and we turn it into a real, scheduled course — the same lessons, planner and records everything else here runs on.

How it works

  1. Step 1
    You show us the contents page

    A photo of the table of contents is enough — the page at the front listing the chapters and units. Title and edition works too.

  2. Step 2
    We read it chapter by chapter

    We scan that contents list and turn each chapter and section into real lessons, in the order the book teaches them, at a pace that fits your year.

  3. Step 3
    It runs like anything else here

    Scheduled into the planner, ticked off per kid, and counted in your records exactly like a course we wrote ourselves.

Included in every plan. No limit on how many books you bring, and no extra charge per book or per child.

Science programs families bring us

If yours is on this list, it works. If it is not, it almost certainly still works — these are just the ones we see most.

  • Apologia Science — the Exploring Creation series
  • Mystery Science — the video-led lessons with a hands-on activity
  • Berean Builders — Jay Wile's science-through-history sequence
  • Elemental Science — the classical-model science guides
  • BJU Press Science — the textbook-and-lab sequence
  • Abeka Science — the traditional textbook programme
  • Real Science-4-Kids — the short chapter books by discipline
  • Nancy Larson Science — the fully scripted elementary programme
  • Building Foundations of Scientific Understanding — the BFSU volumes
  • Generation Genius — the NGSS-aligned video library
  • Sassafras Science — the narrative science adventures

We are not affiliated with any of these publishers, we do not sell their books, and nothing here is a ranking of them. They are listed because a family may already own one.

We are not affiliated with any publisher named on this page, we do not sell their books, and nothing here ranks or rates them. They are listed because a family may already own one and we can bring it in. We deliberately quote no prices for them — those change, and a stale figure of ours is worse to a parent than no figure at all. Everything described as “Included” is our own work and is covered by one subscription, for every subject and every child on the account.
