The Year Theory
Becomes Discovery
From acid chemistry to the mechanics of motion to other solar systems, your child covers every major science discipline in one complete Grade 7 year. Chemistry, biology, physics, geology, and astronomy. Built on correct models and built to last.
Solar Systems
Science that teaches
why, not just what
Most Grade 7 curricula teach properties — they tell students what things are without explaining why they work. RS4K teaches the actual mechanism. Your child learns why acids neutralize bases, why cells work the way they do, why objects follow curved paths. That is what stays.
Chemistry that goes below the surface. Acids, bases, pH, neutralization, and nutritional chemistry — each grounded in atomic theory your child already understands.
Biology from molecules to ecosystems. The microscope, protists, fungi — connected through the same framework, not taught as isolated facts.
Designed by Dr. Rebecca Woodbury — PhD biochemist, M.Ed. Curriculum & Instructional Design. No science background needed to teach it.

Each chapter builds on the atomic framework, from acid chemistry all the way to other solar systems.

From acid chemistry
to other solar systems
Book 6 begins where chemistry meets life, how acids and bases drive biological reactions, and ends by asking whether other solar systems could support life too. Every chapter earns the one that follows it.
The circumstellar habitable zone. Students ask whether other solar systems could support life and have the chemistry to understand the actual answer.
One coherent arc. Acids to astronomy. Every discipline connected. One complete Grade 7 year.
Grade 7 students ready
to understand the real mechanisms
