Power up your STEM lineup with three classroom-proven resources that blend engineering design, energy devices, and core physics skills. Students build and test ember-guard prototypes (constraints, budgets, protocol, leaderboard), crack escape-style energy stations (diagram sort, circuit riddle, device flows), and run Newton’s Laws & Friction investigations (editable data tables, analysis prompts, CER). Every pack includes teacher notes, student pages, and complete answer keys. Ideal for s
