Helicopter Autorotation Blade Pitch STEM Lab (AERO03)

Transform simple paper whirlybirds into a rigorous, quantitative study of rotary aerodynamic forces with the Helicopter Autorotation Blade Pitch STEM Lab (AERO03)! Designed for Middle School Physical Science, Physics, Earth & Space Science, Math, and STEM classes, this 3-page, print-ready lab packet challenges students to investigate how blade pitch angle and ballast mass impact autorotation lift, terminal velocity, and emergency landing descent rates.

What Is Included in This 3-Page Packet?

• 📋 Page 1: Teacher Guide & Lesson Plan

  Features NGSS alignment (MS-PS2-2 Forces & Motion, MS-ETS1-2 and MS-ETS1-3 Engineering Design), key rotary aerodynamics concepts, drop height testing setup directions, expected learning goals, rotor folding tips, and a complete teacher answer key.

• 🚁 Page 2: Student Mission Card & Blueprint

  Hooks students with a real-world aerospace engineering mission to design unpowered emergency supply drop gliders. Includes material constraints (paper templates, paper clips, ruler, protractor, scissors, tape, stopwatch) and a dedicated schematic sketching area to diagram rotary force vectors (lift, drag, gravity, rotational torque).

• 📊 Page 3: Testing Log & Scientific Reflection

  Features a structured drop testing table recording blade pitch angle in degrees, ballast paper clip count, drop height in meters, air time in seconds, and descent velocity in meters per second. Includes an applied math section to calculate Average Descent Velocity (m/s) and Velocity Reduction Efficiency, followed by reflection questions analyzing airflow-to-torque conversion and engine-failure landing physics.

Educational Value & Key Benefits:

• Quantitative Physics with Low-Cost Materials: Uses basic paper, protractors, paper clips, and stopwatches to measure velocity reduction and rotational mechanics.

• Integrates Geometry & Physics Math: Connects angle measurement, time-distance velocity formulas, and percentage efficiency calculations directly to drop testing.

• Versatile Science Integration: Ideal for physical science forces & motion units, engineering design challenges, sub plans, or hands-on STEM activity days across Grades 6–8.
