Unplugged STEM Station Labs Bundle

A massive 5-unit bundle of unplugged STEM rotation packs covering seismic design, water filtration, solar grids, cyber security, and rocketry engineering. Save 20% off individual pack prices with the complete Unplugged STEM Station Centers Bundle! This massive collection features 5 complete engineering units designed to bring hands-on design, applied math calculations, technical blueprint drafting, unplugged computer logic, and real-world disaster case studies directly to your 4th through 8th-grade classroom. Every single pack in this series is 100% unplugged—requiring zero screens, devices, or expensive equipment kits. Each unit is structured for a seamless 60- to 75-minute rotation lab or multi-day STEM project using standard classroom supplies. Included Units in This Bundle: Pack 1: Earthquake Engineering & Seismic Design: Index card towers on shake tables, structural efficiency math, and the 1989 San Francisco Bay Bridge collapse case study. Pack 2: Water Filtration & Environmental Engineering: Multi-stage filter columns, flow rate calculations, and The Flint Water Crisis case study. Pack 3: Solar Power & Smart Grid Engineering: Solar collector arrays, daily watt output math, smart grid flowcharts, and The 2003 Northeast Blackout case study. Pack 4: Cyber Security, Encryption & Unplugged Coding: Caesar cipher encryption wheels, binary math, password cracking algorithms, and The Y2K Bug case study (Includes printable cipher templates). Pack 5: Aerospace & Rocketry Engineering: Straw rocket prototypes, thrust-to-weight ratio calculations, center of gravity blueprints, and the Apollo 13 case study.
