Homeschool Science Curriculum — Complete Guide for K-12 Christian Families
Homeschool science curriculum gives Christian families a choice that public school removes: whether to teach from a biblical creation framework, an intelligent design framework, or a conventional evolutionary framework. That choice is legally protected in all 50 states for homeschool families and is one of the primary academic reasons families choose homeschool over public school. This guide covers the top homeschool science programs, the full K-12 scope and sequence, lab science at home, and how to choose a program that matches your family’s worldview and your student’s academic goals.
This guide is part of Zion Academy’s homeschool subjects curriculum guide resource library for homeschool families.
Science is also the homeschool subject most parents feel least qualified to teach at the high school level — chemistry, physics, and advanced biology require content knowledge that many parents do not have. This guide covers the programs that solve that problem, including video-based and online homeschool science courses that deliver high school lab science without requiring a parent with a science degree.
Zion Academy’s curriculum guide covers how science integrates into the full K-12 academic program across all 50 states.
What Top Homeschool Science Curriculum Programs Are Available?
What Is Apologia Educational Ministries — The Standard in Christian Homeschool Science?
Apologia is the most widely used Christian homeschool science curriculum in the United States, built on a young-earth creation science foundation and designed specifically for homeschool use. Apologia’s science curriculum covers grades K through 12 in 2 series: the Exploring Creation elementary series (grades K through 6) and the high school science sequence (grades 7 through 12). The Exploring Creation series covers zoology (2 volumes), botany, astronomy, anatomy/physiology, chemistry/physics, and general science in a conversational, first-person narrative style that reads as if a knowledgeable adult is teaching the child directly.
The Apologia high school sequence begins with Exploring Creation with General Science (grade 7) and Physical Science (grade 8), then moves to Biology, Chemistry, Physics, and Advanced Biology in grades 9 through 12. Each high school course is designed as a 1-credit lab science course with labs built into the curriculum using household materials or simple lab kits available separately. Apologia’s biology, chemistry, and physics courses are accepted by college admissions when accompanied by an accredited transcript. Apologia also offers online academy courses for families who want video instruction by a certified teacher rather than parent-led instruction.
Answers in Genesis — Young-Earth Creation Science
Answers in Genesis (AiG) publishes the Answers Bible Curriculum’s science components and the God’s Design for Science series, covering grades 1 through 8 from a young-earth creation science perspective. AiG’s curriculum is more explicitly apologetics-oriented than Apologia — it includes direct engagement with evolutionary arguments and systematic responses from a biblical standpoint. The God’s Design series is organized into 4 product groups: Life (plants, animals, human body), Physical World (simple machines, forces, matter), Space and Earth (universe, earth, weather/water), and Our Universe, with each group covering grades 1-8 in 3 volumes.
AiG is the right choice for families who want science curriculum that explicitly prepares students to understand and respond to evolutionary claims from a biblical creation standpoint, not just to ignore them. AiG science curriculum integrates apologetics training into science content in a way that Apologia’s curriculum does not.
Real Science-4-Kids — Content-Neutral, Rigorous Academics
Real Science-4-Kids (RS4K) is a secular-compatible science curriculum published by Gravitas Publications, covering pre-chemistry, pre-biology, pre-physics, and pre-earth science in grades K through 5, with full high school chemistry, biology, and physics courses. RS4K takes no position on origins — the curriculum teaches the scientific content without evolutionary narrative framing or creation science framing, leaving worldview integration to the family. The curriculum is written at a rigorous academic level: the Level 1 chemistry course for grades 1-4 uses accurate chemical nomenclature, introduces the periodic table, and teaches atom structure as real science content rather than simplified analogies.
RS4K is used by both secular homeschool families and Christian homeschool families who want rigorous academic science content and prefer to address worldview questions through Bible and apologetics curriculum separately rather than integrating them into science. It is also used by dual-perspective families where the parents hold different views on origins and want neutral science instruction.
BJU Press Science — Christian, Structured, Complete
BJU Press Science is a complete K-12 science curriculum from Bob Jones University Press that integrates a Christian worldview throughout and covers all standard science content areas at each grade level. BJU Press science is more structured and textbook-based than Apologia, with defined chapter tests, teacher editions with scripted lessons, and a scope and sequence aligned to college-prep standards. BJU Press Science is available in 2 forms: traditional textbooks for parent-taught homeschool and Distance Learning video courses for families who want certified teacher instruction.
BJU Press high school science covers Biology, Chemistry, Physics, Earth Science, and Marine Biology, each as a 1-credit lab science course. BJU Press Distance Learning science courses include lab materials sent to the student’s home and online lab videos for labs that cannot be conducted at home. BJU Press is the strongest choice for Christian homeschool families who want a rigorous, traditional science curriculum with a complete teacher’s guide and grading system.

This page covers the specific content, apologetics approach, and program comparisons for creation science in homeschool.
The Creation vs. Evolution Question in Homeschool Science
Christian homeschool families can teach creation science without legal restriction in all 50 states. The US Supreme Court’s Edwards v. Aguillard decision (1987) prohibits teaching creation science in public schools as a matter of Establishment Clause law. That ruling applies exclusively to government schools. Private schools and homeschool families operate outside the Establishment Clause, and parents hold complete curriculum authority over the content their children receive. No state homeschool law prohibits teaching any particular scientific framework.
The practical question for Christian homeschool families is not whether they can teach creation science — they can — but what curriculum best equips their students to understand both the biblical creation account and the scientific content required for college admission. The answer is a 3-part curriculum: first, rigorous creation science content that explains what the young-earth or old-earth position holds and why; second, exposure to the arguments for evolutionary theory so students can engage them accurately; third, apologetics training that connects origins science to theological foundations. Apologia covers point 1 best. AiG covers all 3. No secular science program covers any of the 3.
Students who apply to secular colleges with Apologia or BJU Press transcripts are not disadvantaged in admissions when the courses are labeled correctly (Biology, Chemistry, Physics) and the grades are issued on an accredited transcript. Admissions officers evaluate lab science credit by course title and credit hours, not by the textbook used. What matters for college admission is that the student completed 3 to 4 lab science credits in high school, not which publisher produced the textbook.
Lab Science at Home — How to Run Experiments in Your Homeschool Program
Lab science at home is achievable at every grade level from kindergarten through 12th grade, and no homeschool family needs a professional laboratory to complete a rigorous science curriculum. The 3 options for lab science in homeschool are: built-in curriculum labs, commercial lab kits, and virtual labs.
Built-in curriculum labs are included in Apologia, BJU Press, and RS4K at every level. Apologia’s high school courses include a list of labs for each module using common household materials (vinegar, baking soda, measuring cups, magnifying glass) or materials available at a hardware or craft store. BJU Press Distance Learning includes a lab kit sent to the student’s home. These built-in labs are sufficient to earn the lab science credit designation on a homeschool transcript.
Commercial lab kits for homeschool are available from several suppliers. Home Science Tools is the most widely used supplier for homeschool lab kits, offering curriculum-specific kits for Apologia, BJU Press, and RS4K, as well as general chemistry and biology kits. A complete Apologia Biology lab kit from Home Science Tools costs approximately $100 to $150 and includes dissection specimens, slides, and microscope slides for the full year. A basic microscope for homeschool biology costs $80 to $150 and is sufficient for all microscopy labs in Apologia Biology.
Virtual labs are the third option for high school lab science, particularly for chemistry and physics labs that require equipment or materials that present safety concerns at home. eScience Labs and Labster both offer virtual lab platforms used by accredited online homeschool programs. Virtual labs are accepted by most college admissions as equivalent to in-person labs when documented on an accredited transcript.
Homeschool Science — Grade Progression K Through 12
Grades K Through 2 — Nature Study and Basic Science Exploration
Kindergarten through 2nd-grade science is nature study, observation, and basic inquiry. Students observe plants, animals, weather, and the natural world. They learn scientific vocabulary (classify, observe, predict, record), perform simple experiments (what happens when you mix vinegar and baking soda), and develop curiosity about the created world. Formal textbook science is not required in grades K through 2 — structured nature journals, science read-alouds, and observation-based activities build the scientific disposition that formal study requires later. Apologia’s Exploring Creation with Botany and Zoology series works well as structured nature study at this level.
Grades 3 Through 6 — Life, Earth, and Physical Science
Grades 3 through 6 introduce the 3 major science content areas: life science (biology, ecology, human body), earth science (geology, weather, astronomy), and physical science (matter, energy, forces, simple machines). Most curricula rotate through these 3 areas across 4 years — life in grade 3, earth in grade 4, physical in grade 5, and a survey in grade 6. Apologia’s Exploring Creation series covers specific topics (astronomy, botany, zoology) in each year rather than rotating, making it distinctive in this grade band. BJU Press Science and RS4K rotate through all 3 areas annually.
Grades 7 Through 8 — General and Physical Science
Grades 7 and 8 are the bridge years between elementary science and high school lab science. Most homeschool programs cover general science (scientific method, earth science, life science, physical science survey) in grade 7 and physical science or pre-physical science (matter, motion, energy, waves, electricity) in grade 8. Apologia uses grade 7 for General Science and grade 8 for Physical Science. These 2 years are the preparation for high school Biology, Chemistry, and Physics, which require the scientific method, unit analysis, and graphing skills introduced at the middle school level.
Grades 9 Through 12 — High School Lab Science Sequence
High school science in homeschool requires a minimum of 3 lab science credits for college admission and 4 credits for competitive admissions. The standard sequence is Biology (grade 9), Chemistry (grade 10), Physics (grade 11), and an elective science (grade 12). The most common elective science in Christian homeschool is Advanced Biology (Apologia Marine Biology, Human Anatomy and Physiology, or Advanced Biology in Creation) or Earth Science. All 4 years of Apologia high school science, all 4 years of BJU Press high school science, and all RS4K high school courses count as lab science credits when documented on an accredited transcript.

Frequently Asked Questions About Homeschool Science
What is the best homeschool science curriculum for Christian families?
The best homeschool science curriculum for Christian families is Apologia for families who want a conversational, parent-friendly program with explicit young-earth creation science integration, or BJU Press for families who want a structured, textbook-based program with a complete teacher’s guide and distance learning option. Answers in Genesis is the best choice for families who want explicit apologetics training alongside science content. Real Science-4-Kids is the best choice for families who want rigorous academic content and prefer to address worldview separately.
Do homeschool students need lab science for college admission?
Homeschool students need 3 lab science credits for most 4-year university admissions and 4 lab science credits for competitive university admissions. The 3-credit minimum is typically Biology, Chemistry, and Physics. Home labs conducted with commercial lab kits, built-in curriculum labs, or virtual lab platforms all count toward the lab science designation when documented correctly on an accredited transcript. Zion Academy’s accredited transcripts document lab science credits in the format colleges expect.
Can I teach high school chemistry and physics at home without a science background?
High school chemistry and physics can be taught at home without a science background using 3 tools: video-based curriculum (Apologia online academy, BJU Press Distance Learning), dual-enrollment at a community college, or an accredited online homeschool program like Zion Academy where certified science teachers deliver instruction. Most homeschool parents who are not scientists successfully support high school chemistry and physics by using the teacher’s edition answer keys to check student work while the video or online instruction delivers the content.
