The Galton Board is a professional statistical tool used to explain the statistical distribution of molecular speed and to study models of random phenomena. It serves as a teaching tool for stochastic phenomena, statistical distribution laws, and explaining the rate of motion of gas molecules. Key benefits Visual demonstration of speed distribution: When rotated, steel balls bounce randomly and form an approximate bell curve, allowing observation and analysis of speed distribution. Clarifies stochastic models: Helps users see how random events aggregate into a predictable distribution, supporting learning about probability and kinetic theory. Classroom friendly and educational: Simple to operate, suitable for classroom demonstrations, educational displays, and engaging physics enthusiasts. Durable construction: Made from organic glass plate with a row of nails, Vshaped grooves, insert plates, and notches, designed to withstand regular use. How it works By rotating the Galton Board, steel balls bounce randomly off a triangular array of nails, producing a distribution of ball counts in the bins that approximates a bell curve. This provides a clear visual representation of speed distribution and related statistical laws.
