Wind Turbine Blade Aerodynamics STEM Lab (PHY03)

Bring renewable energy physics, kinetic-to-electrical energy transformations, aerodynamic pitch vectors, and voltage improvement math to life with the Wind Turbine Blade Aerodynamics STEM Lab (PHY03)! Designed for Middle School Physical Science, Physics, Earth & Space Science, Math, and STEM classes, this 3-page, print-ready lab packet challenges students to engineer custom turbine blades and measure real electrical output.

What Is Included in This 3-Page Packet?

• 📋 Page 1: Teacher Guide & Lesson Plan

  Features NGSS alignment (MS-PS3-1 Kinetic Energy Relationships, MS-PS3-5 Energy Transfer, MS-ETS1-2 Engineering Design), key aerodynamic and electrical concepts, fan station setup instructions, testing safety tips, and a full teacher answer key.

• 💨 Page 2: Student Mission Card & Blueprint

  Hooks students with a clean energy engineering challenge to design efficient wind farm turbine rotors. Includes material constraints (hobby DC motor hub, cardstock, wooden spars, masking tape, protractor, scissors, ruler, multimeter) and a dedicated schematic sketching zone to diagram pitch angles, surface area, rotational torque, and air lift vectors.

• 📊 Page 3: Testing Log & Scientific Reflection

  Features a structured lab data table tracking blade count, blade pitch angle in degrees, generated voltage output in millivolts or volts, and rotation stability notes. Includes an applied math section to calculate Voltage Improvement Percentage across design iterations, followed by reflection questions analyzing lift vs. drag balances, angle efficiency, and energy transfer steps.

Educational Value & Key Benefits:

• Hands-On Energy Transformation Physics: Connects wind kinetic energy directly to mechanical shaft rotation and electromagnetic induction voltage output.

• Integrates Applied Math & Percentage Math: Teaches students how to read digital multimeters and compute percent change math across engineering trials.

• Low-Cost High-Engagement STEM: Uses accessible classroom materials like cardstock, skewers, tape, small DC motors, and a fan for an unforgettable physical science experiment across Grades 6–8.
