Back to School STEM Activity: Marble Maze Gravity Challenge (BTS18) | Middle School Physics Lab (Grades 6-8)

? BACK TO SCHOOL STEM ACTIVITY: MARBLE MAZE GRAVITATIONAL CHALLENGE (BTS18)

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

Master gravitational acceleration, rolling friction, and momentum control! The Marble Maze Gravitational Challenge (BTS18) challenges middle school student teams to act as mechanical engineers, constructing a hand-held tilt maze inside a box lid using straws and tape to guide a marble through complex switchbacks for maximum time.

Students explore gravitational force vectors, incline angles, rolling friction, momentum, and controlled traversal speed calculations (s = d / t)!

? WHAT'S INCLUDED IN THIS 2-PAGE PACKET?

• ? Page 1: Student Mission Card & Blueprint: Real-world mechanical controls and game physics scenario. Clear material constraints box (1 box lid, 15 straws, tape, 1 marble, gravity-driven tilt rule, 4-turn minimum requirement). Dedicated Maze Vector & Vector Pathway Blueprint sketching zone for pre-build path layout, trap placement, and switchback planning.

• ? Page 2: Testing Log & Scientific Reflection: Structured Data Testing Table (track path modifications, total traversal time in seconds, and stuck points across 3 trial runs). Applied Math Connection (calculate controlled marble traversal speed in cm/s using s = d / t). Physics reflection questions analyzing gravitational incline vectors, rolling friction, and momentum conservation.
