Apologia Science is the dominant science curriculum in Christian homeschooling, spanning K–12. The elementary Young Explorer series — including single-topic titles like Astronomy, Botany, Zoology, Anatomy, and Chemistry and Physics — is read-aloud and multi-age, letting one book teach several grade levels of siblings at once, and can be studied in any order.
Middle and high school shift to a conversational textbook written directly to the student, with a lab-based high school sequence that colleges recognize. Notebooking journals (sold separately) provide structured space for narration, diagrams, and lab reports.
Best for Christian families wanting a rigorous, faith-integrated science sequence, from gentle elementary read-alouds through college-prep high school coursework.
One of the strongest home-based options for students headed toward college science courses.
Real lab experiments and notebooking build lasting understanding, not just reading comprehension.
One elementary book can teach several grade levels of siblings at once.
