Homeschool Science Curriculum
What actually works — written by someone who scored 1,307 homeschool curricula on 10 dimensions, including how seriously they take lab work.
The short version
Science is where homeschool either soars or stalls. The kid who loves dissection at 8 is the kid who picks bio at 18; the kid who only ever read about photosynthesis is the kid who tests out of biology and never takes another science class. So the curriculum question reduces to one thing: does the program actually do experiments, or does it just describe them?
That, plus secular vs. religious framing, narrows the field of "best homeschool science curriculum" from hundreds of options to about eight programs that matter. Don't pick by box appeal. Pick by lab quality.
What to look for
- Real labs, not lab descriptions — every chapter should have hands-on experiments with materials lists, not just "imagine you mixed these"
- Honest framing — the program is upfront about whether it's secular, classical, or faith-integrated, so you know what you're buying
- Spiral or mastery, deliberately chosen — either revisits topics with increasing depth (spiral) or covers one branch deeply per year (mastery), but doesn't accidentally do neither
- Lab kits available — pre-packaged supplies you can actually order, not a 40-item scavenger hunt at three different stores
- High school transcript-ready — covers enough hours and lab work that "Biology with Lab" on a transcript means something
The programs that actually work
Apologia (Christian, dominant in religious homeschool)
The default for religious homeschoolers. Rigorous high school sequence — Exploring Creation with Biology, Chemistry, Physics — that's widely accepted by Christian colleges and most state universities. Strong lab work, conversational tone, well-supported lab kits from Home Science Tools. Treats evolution as a worldview question; if that's a dealbreaker for you, this isn't the program. If it's a feature, Apologia is the most-used homeschool science curriculum in America for a reason.
Berean Builders (Christian, classical, by Jay Wile)
Written by the same author who built Apologia's original high school courses, but classical-trajectory and chronologically organized — science taught alongside the history of the people who discovered it. Strong on hands-on labs. The high school courses (Discovering Design with Chemistry, etc.) are now a credible alternative to Apologia for families who want classical pedagogy without sacrificing rigor.
Real Science 4 Kids (secular, K-12 spiral)
Probably the strongest secular option. Spirals through chemistry, biology, physics, geology, and astronomy every year, going deeper each pass. Treats mainstream science as mainstream science. Lab books are separate purchases but well-designed. Good fit for families who want a coherent K-12 spine without religious framing.
Elemental Science (classical, secular)
A classical four-year cycle (biology, earth/astronomy, chemistry, physics) that pairs with whatever spine you're already running — Story of the World, Well-Trained Mind, anything. Light teacher prep, real labs, and you can layer it onto a literature-based curriculum without rebuilding your whole schedule. Best for families who already know they're classical.
Mr. Q's Affordable Science (free PDFs, secular)
Surprisingly good, surprisingly free. Mr. Q (a former public school science teacher) gives away the Life Science PDF and sells the rest cheap. Secular, lab-rich, written like a real teacher actually talks. Not the prettiest layout — but if budget is a constraint and you don't need a glossy book, this punches several weight classes above its price.
What to avoid
- Textbook-only programs that skip lab work entirely ("read chapter 4, answer questions" with no experiments)
- "Science encyclopedia" curricula that read like reference books — pretty pictures, no investigation, no scientific method
- Programs that hide weak content behind glossy production — Usborne-style box appeal without an actual scope and sequence
- Anything that promises a "complete K-12 science program" in one slim workbook a year. Real science takes time.
Find your match in 5 minutes
Our matcher asks 7 questions about your child — grade, secular vs. religious preference, lab tolerance, what you've already tried, budget — and ranks options from our database of 1,307 curricula scored on 10 dimensions including lab depth and transcript-readiness. Free, no signup required to see recommendations.
A dedicated science mode (with lab-budget filters and high-school-transcript planning) is in the works.
Common questions
Do I need lab equipment to homeschool science?
Yes — at least the basics. Science without labs is just reading about science. For elementary, kitchen materials and a $30 microscope. For middle school, add a balance, thermometer, and a basic chemistry kit. For high school, plan on $200-500/year in supplies or use a co-op lab.
Apologia vs. Real Science 4 Kids — which is better?
Different products for different families. Apologia is Christian, young-earth, dominant in religious homeschool — rigorous, but treats evolution as a worldview question. Real Science 4 Kids is secular, spirals K-12, and treats mainstream science as mainstream. Pick on framing, not just rigor.
Is BookShark Science enough on its own?
For elementary, yes — it's a complete secular literature-based program with included experiment kits. For middle school it's still solid but lighter on labs. For high school, most families switch to a dedicated bio/chem/physics program or dual-enroll.
How do I teach high school chemistry without a home lab?
Buy a program-matched lab kit (Apologia and Berean Builders both sell them), use a co-op for the lab day only, or dual-enroll at community college. Avoid pure-textbook chemistry with no labs — colleges notice.
