Rubber Band Ballista STEM Kit: Elastic Energy Launcher

(Science Small Production: Kinetic Energy Explorer)

🎯 Key Features & Learning Value:

  1. Physics of Elastic Energy:

    • Build a functional rubber band-powered launcher demonstrating potential → kinetic energy conversion.

    • Quantify variables: Stretch length vs. projectile distanceBand thickness vs. force.

  2. Engineering Design:

    • Test trigger mechanisms, barrel angles, and frame stability.

    • Optimize for accuracy, range, or power (safely!).

  3. Historical Connection:

    • Relates to ancient torsion artillery (e.g., Roman ballistae) and modern catapult principles.


📦 Kit Includes:

  • Pre-cut wooden frame pieces

  • Multiple rubber band strengths

  • Adjustable launch platform

  • Manual with experiment prompts

🎯 Skills Developed:

✅ Scientific Method: Hypothesize, test, measure, refine
✅ Physics Principles: Hooke’s law, trajectory, elasticity
✅ Critical Thinking: Troubleshoot jams/inefficiencies

⚙️ Specifications:

  • Age: 8+ (Safe for classrooms)

  • Build Time: 25 mins

  • Max Range: 3m+ (adjustable)

  • Tools: No glue/screws – friction-fit assembly

💡 Perfect For:

  • Physics labs on energy types

  • Math integration (graphing distance/angle)

  • History lessons on ancient warfare tech

  • STEM clubs & science fairs

"皮筋枪" = Rubber Band Gun – transforms play into rigorous physics exploration!
Safety Note: Foam projectiles only | Eye protection recommended


🎓 Educational Prompts:

  1. "How does band stretch distance affect kinetic energy?"

  2. "Design a target challenge: Accuracy vs. Power trade-offs"

  3. "Compare your launcher to medieval siege engines"


Why Teachers Love It:

  • Teaches energy concepts through tangible excitement

  • Fosters iterative design ("Why did my projectile veer left?")

  • Aligns with "动手动脑" (hands-on/minds-on) pedagogy
