Back to School STEM Activity: Paper Wind Turbine Challenge (BTS15) | Middle School Physics Lab (Grades 6-8)

? BACK TO SCHOOL STEM ACTIVITY: PAPER WIND TURBINE CHALLENGE (BTS15)

2-Page Printable STEM Packet | Print-Ready PDF Format

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'S 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 cm, and lift speed in seconds across 3 prototype tests). Applied Math Connection (calculate mechanical work output in Joules: Work = mass x gravity x distance). Physics reflection questions analyzing aerodynamic blade pitch, drag trade-offs, and energy conversion chains.
