Complete curriculum for all three middle school levels, ready to teach from day one. This set includes all three 3-Book Trios for Real Science-4-Kids Books 5 through 7 (nine books), plus the Middle School Experiment Book, ten books in total. Each level comes as a 3-Book Trio: the student textbook, the student pages, and the teacher pages. Built for middle school learners ready to go deeper, the set is open and go, with everything printed and ready to teach. The Atoms First Sequence Continues: Like the elementary books, Books 5 through 7 are not single-subject volumes. Each one draws on chemistry, biology, physics, geology, and astronomy, always through the Atoms First approach, and builds on the foundation established in Books 1 through 4. 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. What's in Each 3-Book Trio: Student Textbook: Comprehensive middle school science with greater depth, detail, and scientific vocabulary Student Pages: Printed lab worksheets, critical-thinking questions, and review exercises aligned to every chapter, open and go with nothing to photocopy Teacher Pages: Complete lesson guides with answer keys, discussion questions, and scheduling suggestions, so you can teach with confidence even without a science background Also Included: The Middle School Experiment Book (Science Books 5 through 7) gathers the hands-on experiments for all three middle school levels in one volume. Three levels. Nine books plus the Middle School Experiment Book. A complete middle school science curriculum, open and go. Also available: Elementary Set (Books 1 through 4) and the RS4K Science Home Library (all 7 books).
