THSF Science vs Apologia Science

Which Homeschool Science Curriculum Is Right for You?

An honest, side-by-side look at both curricula — real costs, real pros and cons, and a clear “choose this one if…” verdict based on fit, not hype. We don't name a flat winner because the right choice depends entirely on your child.

We compare how each one teaches, not what each one charges — prices change, and a stale figure of ours helps nobody.

Ours is included. Every subject, every child on your account, no per-book or per-child fee — and that covers the planner, the subject tutors and your state's records too. Most curricula are bought one subject at a time, per child, every year.

Choose THSF Science if…

Choose Apologia Science if…

Pedagogyphenomena-first + NGSS-aligned
Parent involvementLow — kid-independent
Religious lensSecular
Age rangeK-12
GradesK – Grade 12
Time per day25-35 min

Strengths

  • 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

Weaknesses

  • A new curriculum, written this year
  • No lab kit and no hands-on experiments; this teaches the science, it does not replace a dissection tray or a microscope

Families who want a real high-school science sequence at home without assembling four separate courses
