Rubber Band Ballista STEM Kit: Elastic Energy Launcher
(Science Small Production: Kinetic Energy Explorer)
🎯 Key Features & Learning Value:
Physics of Elastic Energy:
Build a functional rubber band-powered launcher demonstrating potential → kinetic energy conversion.
Quantify variables: Stretch length vs. projectile distance, Band thickness vs. force.
Engineering Design:
Test trigger mechanisms, barrel angles, and frame stability.
Optimize for accuracy, range, or power (safely!).
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:
