Start Science the Atoms-First Way

Start with the Placement Quiz. It quickly confirms your best starting point. For most early learners and new homeschoolers, Book 1 is the right beginning. Once you purchase, use the Digital Hub as your main navigation for teaching resources.

The Digital Hub is where your digital resources are organized—Teacher Dashboards, digital textbooks, labs, quizzes, and more—so you can teach from one place. It is designed to be the primary navigation for your digital teaching materials.

The Teacher Pages provide an open-and-go format with everything planned for you. Each lesson includes 35–45 minute activities, and the weekly schedule varies naturally by chapter—some weeks are 4 days, others are 3 days. Simply follow along and teach.

Yes. RS4K is designed for parents without a science background. The atoms-first approach gives you a clear framework, and the Teacher Pages guide you through each lesson. If you're unsure, start with the Placement Quiz to remove doubt about where to begin.

Atoms are the unifying idea across sciences. Most elementary programs teach disconnected topics; RS4K starts with the building blocks of everything. Students get a framework that connects chemistry, biology, and physics from the beginning.
