Back to School STEM Activity: Paper Wind Turbine Challenge (BTS15) | Renewable

💨 Back to School STEM Activity: Paper Wind Turbine Challenge (BTS15) Harness clean energy physics and aerodynamic engineering with a hands-on mechanical challenge! The Paper Wind Turbine Challenge (BTS15) challenges middle school student teams to act as renewable energy engineers, designing a rotor blade assembly out of paper and skewers that spins in front of a fan to lift a string-bound payload. Students explore aerodynamic blade pitch, rotational torque, kinetic-to-mechanical energy transformations, and mechanical work output math (Work = m x g x d)! 📦 What is Included in This 2-Page Packet: Page 1: Student Mission Card & Blueprint: Real-world wind energy and mechanical rotor engineering scenario. Clear material constraints box (paper/cardstock, skewer axle, straw sleeve, string, paperclip, fan testing, 15 cm lift goal). Dedicated Aerodynamic Blade Pitch & Rotor Blueprint sketching zone for planning blade geometry, pitch angles, and axle winding loops. Page 2: Testing Log & Scientific Reflection: Structured Data Testing Table: Track blade counts, pitch configurations, vertical lift distance in centimeters, and lift speed in seconds across 3 prototype tests. Applied Math Connection: Calculate mechanical work output in Joules ($\text{Work} = \text{mass} \times \text{gravity} \times \text{distance}$). Physics Reflection Questions: Analyze aerodynamic blade pitch, blade count drag trade-offs, and energy conversion chains. 📐 Core STEM Skills Covered: Aerodynamic Engineering, Blade Pitch Angles & Wind Energy Rotational Kinetic Energy, Mechanical Work & Power Data Logging, Time Tracking (s), Lift Calculations (cm/m), and Work Math (Joules) Iterative Blade Tuning and Energy Transformation Mechanics 💡 Why Teachers Love This Resource: High-Impact Clean Energy Lab: Demonstrates how wind turbines convert moving air into real mechanical work in a memorable, visual way! Low-Cost Materials: Uses simple paper, wooden skewers, straws, string, and paperclips. Clean 2-Page Layout: Keeps student rotor schematics, mechanical work math, and physics reflections organized on a single front-and-back printable sheet. Format: High-resolution, print-ready PDF format (2 Pages).
