Pair with the Dashboard
The Experiment & Activity Kit
Every hard-to-find and non-household experiment item for the grade, pre-assembled and hand-packed in small batches. No supply hunting. No guessing quantities. We can personalize each kit with your child's first name.
Batch-Summer: order by August 5, ships by August 14. Available in United States.
What's inside every dashboard
Everything needed. Nothing to hunt down.
Every resource is organized by unit and lesson, accessible from the moment you subscribe.
Lesson plans
Structured lesson plans for every lesson in every unit. Teacher notes flag where atomic language matters most, so you stay accurate without becoming an expert.
Student printables
Print-ready student pages for every lesson. No formatting, no prep. Open, print, teach.
Curated digital readers
21–24 digital readers per grade, organized by unit and tagged by subject area so you match reading to your child's pace.
Atoms First language notes
Every unit flags common misconceptions and provides the correct atomic framing. You teach the mechanism, not the metaphor.
Connected science topics
Each grade weaves biology, physics, geology, and astronomy together through an atomic lens, so topics connect rather than pile up as isolated facts.
Best on tablet
The digital readers work best on a tablet, which offers a full-screen reading mode for comfortable, distraction-free reading. Lesson plans and printables open just as easily from your computer.
The Atoms First Difference
Science your child will never have to unlearn.
Most K–2 science programs teach metaphors: plants "want" sunlight, objects "want" to fall. RS4K starts at the atomic level from day one. Forces are atomic pushes and pulls. Sound is atoms vibrating. Weather is atoms moving through Earth's spheres. The mechanism is real. At K–2, children absorb it without effort. No unlearning. No retrofitting. Just science that builds.
Built for parents who read the fine print.
You've evaluated curricula. You've spotted the programs that look rigorous until you open them. RS4K was written by the scientist and educators who share your skepticism of "fun" science that skips the mechanism.
Dr. Rebecca Woodbury, PhD and M.Ed, built the Atoms First sequence so students encounter the correct foundational framework from Kindergarten forward. Decades of use in homeschool homes, co-ops, and enrichment programs back it.
Each grade dashboard works for your child's actual readiness, not an arbitrary grade label.
Lesson plans are written so you teach the atomic mechanism accurately, even if chemistry isn't your background.
RS4K has been refining science education for homeschoolers since before most modern curricula existed.
K through Grade 2 covered in three dashboards. Continue with Books 1 through 7, designed for grades 2 and up, with no gaps and no overlap.
Start the year with real science.
Choose one grade or all three. Each dashboard includes 18-month access, starting immediately.
