What Others Are Saying About RS4K

    • “It is a fantastic book to teach science to kids with lab experiments adapted for each and every unit using the Scientific Method. For my daughter science with Exploring the Building Blocks is a unique program to enjoy as a family. (Exploring the Building Blocks of Science Book 1 Set)”

      — Carlos A.

    • “This add on kit makes the lessons super easy to do. You may have some of these items around the house but having it in one box makes these lessons way more motivating and doable! Also, some items are pretty obscure and/or a pain to find anywhere else so it’s perfect for the price! (Exploring the Building Blocks Book 3 Kit)”

      — Melissa S.

    • “Its wonderful! Does not condescend, but is easier for younger kids to conceptualize REAL science terms. I love that she will not have to relearn science with each academic age (elementary/middle/high school). Other curriculum seems to think that little kids can only understand "baby" ideas. (Exploring the Building Blocks of Science Book 2 Student Text)”

    Introducing the Building Blocks series from Rebecca Keller, PhD, and Real Science-4-Kids. Cover fundamental aspects of five science subjects over the course of one year. Building Blocks is for children from pre-k or kindergarten through middle school and is focused on using the spiral learning method.

    What is spiral learning?

    Kids learn chemistry, biology, physics, geology, and astronomy with the spiral teaching method. First, teach the basics of each topic. Throughout the year, revisit the basics while adding related details and complexity. The outcome? Children show better long-term mastery of facts and concepts. How cool is that? Plus, spiral learning adapts well to different learning styles. Visual learners revisit and expand topics using images. Verbal learners get to use reading and writing to build upon the lessons that they learned.

    What's included in the Building Blocks of Science curriculum?

    • 5 core disciplines: chemistry, biology, physics, geology, and astronomy
    • 22 chapters for one year of study
    • 44 hands-on experiments each year
