Galton Board A clear, handson demonstration of random processes and statistical distribution. Constructed from plexiglass with a regular array of nails, Vshaped grooves, an insert plate, and notches, this Galton board shows how many identical balls falling through staggered rows of nails form an approximate bell curve. Key features Materials and construction: Plexiglass (organic glass) plate with a rowed nail array, Vshaped slot, insert plate, and bottom collection tray. Durable for repeated demonstrations but should be handled with care to avoid impact. Visual demonstration of probability: Each ball has an equal chance of deflecting left or right at each nail. After passing through N layers of nails with leftright symmetry, the balls collect in a distribution that approximates the normal density curve. Easy operation: Invert the board, pour all balls into the Vshaped slot, insert the plate, flip so the Vshaped slot is at the , pull the insert plate to release the balls, and watch them scatter through the nail array into the bottom slots. Educational focus: Designed for teaching stochastic models, binomial to normal distribution approximation, and the statistical interpretation of molecular speed distributions. Color options: Yellow, Blue, Red. Why choose this Galton board Makes abstract concepts tangible: Converts probability theory into a visible, repeatable experiment that reinforces classroom learning. Reliable teaching aid: Suitable for demonstrations, labs, and exhibits where clear visualization of random processes is required. Clear cause and effect: The arrangement of nails ensures each horizontal position sits midway between two nails on the row below, producing predictable combinatorial outcomes that lead to the bell shape when many trials are run. Use scenarios Classroom demonstrations of probability, statistics, and physics for middle school, school, and introductory college courses. Lab or museum exhibit to illustrate random processes and the emergence of statistical patterns from simple repeated events. Science club activity or handson workshop for exploring experimental design, data collection, and histogram formation. Care and storage The instrument is made from plexiglass and should be handled gently. Do not collide or drop the board. After use, store in a cool, dry place to preserve clarity and function.
