Mechanical STEM Newton's Cradle Kit

Newton's Cradle STEM Kit: Conservation of Energy & Momentum Lab

⚖️ Eco-Wooden Design | Hands-On Physics | Cognitive Development

🌟 Core Learning Principles:

1. Newtonian Mechanics Visualized:

   • Demonstrate energy conservation, momentum transfer, and elastic collisions through iconic swinging spheres.

   • Validate Newton's Third Law: "For every action, an equal and opposite reaction."

2. Quantitative Experiments:

   • Test variables: Drop height vs. swing duration, Sphere mass vs. energy transfer efficiency.

   • Measure oscillation decay to explore energy dissipation (friction/air resistance).

📦 Kit Includes:

• 5 Precision Steel Spheres (equal mass)

• Solid Wood Frame 

• Illustration manual

🧠 Skills Developed:

✅ Scientific Method: Hypothesis → Experimentation → Analysis
✅ Data Literacy: Graph energy decay over time
✅ Critical Thinking: "Why doesn’t the last sphere swing as high?"
✅ Troubleshooting: Adjust string lengths for perfect alignment

⚙️ Specifications:

• Age: 10+

• Assembly Time: 20 mins (tool-free)

• Material: Sustainably-sourced beech wood + stainless steel

🎓 Classroom Integration:

1. Physics Labs:

   • Quantify kinetic → potential energy conversion

   • Compare elastic vs. inelastic collisions

2. Math Connections:

   • Calculate momentum (p=mv)

   • Model exponential decay equations

3. Real-World Links:

   • Pendulum clocks

   • Automotive crash tests

   • Sports physics (golf/tennis ball impacts)

💡 Why Educators Choose This Kit:

• Eco-Wood: Teaches sustainability through material choice.

• Cognitive Growth: Challenges misconceptions about perpetual motion.

• Intelligent Assembly: Precision stringing develops fine motor skills.

✅ Safety & Compliance:

• Rounded edges (splinter-free wood)

• Non-toxic finishes

• Secure sphere containment
