Back to School STEM Activity: Paper Roller Coaster Challenge (BTS13)

Bring gravitational potential energy to kinetic energy conversion, friction management, centripetal force mechanics, banked turn geometry, track slope optimization, and average speed calculations to life with the Back to School STEM Activity: Paper Roller Coaster Challenge (BTS13)! Designed for Middle School Physical Science, Physics, Mechanical Engineering, Math, Homeroom, and STEM classes across Grades 6–8, this 2-page, print-ready lab packet challenges student teams to engineer cardstock paper roller coaster tracks designed to maximize marble ride duration from a 40 cm starting height.

What Is Included in This 2-Page Packet?

• 🎢 Page 1: Student Mission Card & Blueprint

  Hooks students with a real-world amusement park engineering scenario. Includes strict material and design constraints (4 cardstock sheets, 1 meter masking tape, 1 marble, 40 cm fixed starting height, maximum ride duration objective) alongside a dedicated Coaster Track Schematic & Energy Map workspace to diagram track elevation changes, loop geometry, banked turn angles, and energy conversion points (PE to KE).

• 📊 Page 2: Testing Log & Scientific Reflection

  Features a structured lab testing table tracking coaster structural features, total track length in centimeters (cm), and total ride duration in seconds across 3 prototype runs. Includes an applied math section to compute Average Speed in centimeters per second (s = d / t), followed by physics reflection questions evaluating gravitational acceleration, friction reduction along paper joints, momentum maintenance, and centripetal force stabilization during turns.

Educational Value & Key Benefits:

• Hands-On Energy & Motion Physics: Demonstrates how manipulating track slope, drop height, and curve banking regulates marble acceleration and friction loss.

• Integrates Applied Math & Speed Calculations: Teaches students how to convert track length distance and stopwatch time into precise speed metrics (cm/s).

• Low-Cost High-Engagement STEM: Uses simple classroom materials like cardstock, tape, and marbles for an active, high-energy physical science challenge across Grades 6–8.
