Galton Board Probability Distribution Model, 15x11cm Acrylic Statistics Teaching Tool for Education Description

Galton Board What it is A desktop demonstration device that visualizes probability and normal distribution by directing steel balls through a peg array to form an approximate bell curve. Key benefits Makes abstract statistics intuitive: watch random trajectories produce a predictable distribution and reinforce the concept of the normal curve. Engaging teaching tool: ideal for classroom demonstrations where visual observation and instructor guidance build understanding and curiosity. Ready for lab or use: compact desktop size and clear construction let students and educators focus on results and analysis. How it works Principle: rotate the Galton plate to release a stream of precisely measured steel balls. Each ball bounces left or right with equal probability as it passes the peg array, accumulating into a bellshaped distribution matched to the normal curve printed on the panel. Demonstration output: the falling beads form an approximate bell curve that can be observed and analyzed to study velocity and distribution properties. Features Materials: transparent acrylic panels for clear observation and durability, plus accurately sized steel balls for consistent results. Size: 15*11cm, designed for desktop use and easy setup. Performance: peg arrangement and calibrated components produce repeatable statistical patterns for demonstration and experiment. Use scenarios Classroom demonstration: show probability and the law of large numbers during a statistics or physics lesson. Laboratory supplement: use as a handson tool for experiments on distribution and particle behavior. Student exploration: small group activity for observing randomness, collecting counts, and comparing them to theoretical curves. Specifications Name: Galton Board Color options: red and white, gray and white, black and white, Ivory Gray Purpose: Desktop Size: 15*11cm Packing list: 1 * Galton board What makes it stand out Clear acrylic construction and precisely measured steel balls, with a normal distribution curve marked on the panel for direct visual comparison and reliable classroom demonstrations.
