The complete Real Science-4-Kids curriculum, from elementary through middle school.
The RS4K Science Home Library includes all seven 3-Book Trios (twenty-one books), plus the Elementary Experiment Book and the Middle School Experiment Book, twenty-three books in total. Each level, Book 1 through Book 7, comes as a 3-Book Trio: the student textbook, the student pages, and the teacher pages. It is open and go, with everything printed and ready to teach. This is the most complete way to own the full Real Science-4-Kids program.
The Atoms First Sequence:
These are not seven interchangeable books. Each one plays a specific role in building real scientific understanding, in order:
- Book 1: The Atomic Map for Real Scientific Understanding — Students learn what atoms and molecules are, the correct starting point, then use that atomic lens to explore biology, physics, geology, and astronomy.
- Book 2: The Scientific Toolkit for Independent Discovery — Students learn how scientists investigate, building the Scientist's Toolbox of observation, measurement, and models through hands-on practice.
- Book 3: When Atomic Theory Explains Everyday Life — Students apply that toolkit to see how atomic theory connects across every science and explains the world around them.
- Book 4: From Atomic Behavior to Complex Systems — Students build from the behavior of atoms up to the complex systems those atoms create.
- Book 5: The Year Science Starts Making Sense — Building on the elementary foundation, the pieces come together with new rigor and depth.
- Book 6: The Tools That Turn Theory Into Discovery — Students extend their scientific toolkit, turning atomic theory into hands-on discovery.
- Book 7: The Capstone Year Where Everything Comes Together — The final level, where the full Atoms First progression culminates.
Every book draws on chemistry, biology, physics, geology, and astronomy, always through the Atoms First approach, so concepts connect instead of sitting in isolated units. Books 1 through 4 are elementary, and Books 5 through 7 are middle school.
What's in Each 3-Book Trio:
- Student Textbook: The core reading text, carefully written and illustrated for each level
- Student Pages: Printed study and lab pages, hands-on experiments guided by the RATATAZ method (Read, Ask, Test, Answer, Talk, and Dazzle), and end-of-chapter quizzes, open and go with nothing to photocopy
- Teacher Pages: Lesson plans, full answer keys, step-by-step experiment instructions, and quiz keys for confident, stress-free instruction, even without a science background
Also Included:
- The Elementary Experiment Book (Science Books 1 through 4): All the elementary hands-on experiments in one volume
- The Middle School Experiment Book (Science Books 5 through 7): All the middle school hands-on experiments in one volume
Every book. Every level. Every component, plus both Experiment Books. One complete science library for your home, open and go.

Trusted by Families & Educators
Best science curriculum out there! Just wanted you to know how much I’ve appreciated teaching my kids from your materials.
As a science teacher, I’ve tried several programs, but RS4K stands out. The emphasis on authentic scientific vocabulary and age-appropriate foundational content makes it easy for my students to grasp complex concepts.
I love how RS4K introduces complex topics like atoms and molecules in an easy-to-understand manner for younger students. My daughter has developed a strong foundation in science and always looks forward to her lessons.
