From Electrons
to Exploring
the Universe
22 chapters across chemistry, biology, physics, geology, and astronomy — including "Are We Alone?" and "Into Space We Go!" The complete advanced Grade 5 science year.

Grade 5 science that puts
kids a full level ahead
While other Grade 5 students review the basics, RS4K students are mastering electron chemistry, wave physics, ecology, and astronomy — in one year.
22 chapters — electrons to the cosmos. Chemistry, biology, physics, geology, and astronomy in one complete year.
Teacher dashboard included. Lesson plans, lab pages, and quizzes for every chapter — nothing to build from scratch.
Designed by Dr. Rebecca Woodbury — PhD biochemist, M.Ed. Curriculum & Instructional Design.
Chemistry · Biology · Physics · Geology · Astronomy
Every chapter builds on the one before it — from the smallest scale to the largest.
The foundation that shows up
when stakes are highest
Grade 5 STEM competitions, gifted program placements, and selective middle school admissions reward the student who built a real science foundation early.
STEM competitions reward early science. Students who covered electron chemistry and wave physics in Grade 5 walk into competitions already speaking the language.
RS4K Grade 5 students stand out in every class that follows — year after year, because the foundation was built right.
Book 4 covers material most schools skip until high school — electron sharing, ecological systems, wave physics, and real astronomy.
Every chapter.

Science Book 4 is available in four formats to fit how your family or school works. See all options and pricing on the product page.
From electrons to
"Are We Alone?"
Science Book 4 starts with how electrons are shared between atoms — and ends with whether anyone else is out there. The final five chapters cover real astronomy: scale, exploration, the search for life.
Grade 5 students ask "Are We Alone?" — and understand exactly why it's a real scientific question.
Electrons to ecology to cosmos. One coherent 22-chapter arc, one grade 5 year.
