Marble Roller Coaster G-Force STEM Challenge (FME02)

Bring gravitational potential energy, kinetic energy conversion, centripetal acceleration, G-forces, and energy efficiency ratios to life with the Marble Roller Coaster G-Force STEM Challenge (FME02)! Designed for Middle School Physical Science, Physics, Math, and STEM classes across Grades 6–8, this 3-page, print-ready lab packet challenges students to engineer foam insulation roller coasters capable of guiding a marble through vertical loops.

What Is Included in This 3-Page Packet?

• 📋 Page 1: Teacher Guide & Lesson Plan

  Features NGSS alignment (MS-PS2-2 Forces & Motion, MS-PS3-1 Kinetic Energy Relationships, MS-PS3-2 Gravitational Potential Energy), key energy physics concepts, track preparation guidelines, troubleshooting tips, and a full teacher answer key.

• 🎢 Page 2: Student Mission Card & Blueprint

  Hooks students with a theme park ride engineering scenario to design high-G vertical loop coasters. Includes material constraints (foam pipe insulation tracks cut in half, glass marble, masking tape, plastic catch cup, meter stick) and a dedicated schematic sketching zone to diagram release elevation, loop entry velocity, centripetal force vectors, and gravity-defying G-forces.

• 📊 Page 3: Testing Log & Scientific Reflection

  Features a structured lab data table tracking drop height in centimeters, loop diameter in centimeters, 360-degree loop completion success, and cup target landing rates. Includes an applied math section to calculate Energy Efficiency Ratios (Loop Height / Drop Height), followed by reflection questions analyzing potential-to-kinetic conversion efficiency, normal force, and surface friction loss.

Educational Value & Key Benefits:

• Hands-On Amusement Park Physics: Connects initial gravitational energy storage directly to loop entry velocity and centripetal acceleration.

• Integrates Applied Math & Efficiency Ratios: Teaches students how to measure vertical track heights and compute energy conservation ratios.

• Low-Cost High-Engagement STEM: Uses inexpensive items like foam pipe insulation, marbles, tape, and plastic cups for an unforgettable physical science lab across Grades 6–8.
