Back to School STEM Activity: Marble Maze Gravity Challenge (BTS18)

Bring gravitational acceleration control, incline angle vector physics, rolling friction management, momentum dissipation on turns, and controlled traversal speed calculations to life with the Back to School STEM Activity: Marble Maze Gravity Challenge (BTS18)! 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 tilt-controlled straw mazes inside recycled box lids to maximize marble traversal time and control.

What Is Included in This 2-Page Packet?

• 🌀 Page 1: Student Mission Card & Blueprint

  Hooks students with a real-world game physics and mechanical controls engineering scenario. Includes strict material and design constraints (1 cardboard box lid, 15 plastic drinking straws, masking tape, 1 marble, gravity-driven tilt rule, 4-switchback minimum requirement) alongside a dedicated Maze Vector & Vector Pathway Blueprint workspace to sketch obstacle pathways, trap hazards, and incline turn angles.

• 📊 Page 2: Testing Log & Scientific Reflection

  Features a structured lab testing table tracking path geometry modifications, total maze traversal duration in seconds, and stuck point hazard locations across 3 prototype trials. Includes an applied math section to compute Controlled Marble Traversal Speed in centimeters per second (s = d / t), followed by physics reflection questions evaluating gravitational vector components, rolling friction coefficient variations along straw walls, and momentum control around 90-degree corners.

Educational Value & Key Benefits:

• Hands-On Gravity & Motion Physics: Demonstrates how altering tilt incline angles and path friction regulates gravitational acceleration.

• Integrates Applied Math & Speed Calculations: Teaches students how to combine track length measurements and timing into precise speed equations (cm/s).

• Low-Cost High-Engagement STEM: Uses simple recycled items like shallow cardboard boxes, straws, and marbles for an active, hands-on physical science lab across Grades 6–8.
