Newton's Cradle

Build your own version of the classic physics toy using simple materials. This project demonstrates the principle of conservation of momentum and pays homage to Isaac Newton, who made many breakthroughs in understanding force, energy, and momentum. Learners also observe the rules of probability. Note: this activity requires the use of super glue. [Activity is publicly available through a web crawler capture on]
