Best Homeschool Science Curriculum

7 curricula in this guide

Homeschool science curricula range from inquiry-based programs with hands-on investigations to traditional textbook approaches and creation-based programs that integrate a Christian worldview. The right pick depends on your goals: college prep, casual exploration, or compliance with state requirements.

Below we feature standout options across worldview and approach. For families wanting NGSS-aligned secular science, Mystery Science and Generation Genius lead. For young-earth Christian science, Apologia has the strongest college-recognition track record. Pair any of these with hands-on lab kits for the strongest learning outcomes.
