Anti-Gravity STEM Challenge: Tensegrity Forces & Equilibrium Lab + 3D Print Bundle

Bring the phenomenon of tensegrity into your classroom with a complete, hands-on physics and engineering investigation. 

Students explore how continuous tension balances isolated compression to create a stable, floating structure that holds real weight. Designed for Middle School, High School, and introductory Engineering courses.

CURRICULUM ALIGNMENT:

• NGSS MS-PS2-2 & HS-PS2-1 (Forces, Motion & Static Equilibrium)

• NGSS MS-ETS1-2 & HS-ETS1-2 (Engineering Design & Optimization)

WHAT’S INCLUDED IN THE BUNDLE:

• 4-Page Student Lab Packet (PDF): Pre-lab inquiry questions, free-body vector diagramming, data collection tables, and load-limit failure analysis.

• Complete Teacher Solution Key (PDF): Worked static equilibrium calculations (11.17 N tare, 13.62 N loaded) and overturn torque stability margins (3.18x safety factor).

• 14-Slide Classroom Presentation Deck (PDF): Visual explanations of tension vs. compression, biotensegrity in nature, and aerospace applications.

• Low-Cost Craft Stick Guide (PDF): Run this lab with popsicle sticks, string, and glue for under $0.40 per student team—no 3D printer required!

• Makerspace 3D Print Files (.STL): Complete set of 4 zero-support STLs (Base, Top platform, Morse friction pegs, and 18mm Calibration Spacer) ready for school 3D printers.

• Teacher Quickstart Guide (.txt): Suggested 3-day pacing guide, material checklist, and troubleshooting tips.
