Galton Board - Dalton Board Probability Demonstration Model with Bell Curve, Effective Statistical Law, for Physical School Laboratory Teaching

HOW TO USE:Turn the apparatus upside down, pour all the balls into the V-groove, insert the insert plate, then flip it over so that the V-groove is on the upper part of the apparatus, pull the insert plate to make the balls fall, the collisions with the peg arrays will be randomly spread out, the pegs are equidistant left and right from each other, and each horizontal position of the upper level is located exactly in the middle of the next level's two pegs, when the balls come into contact with the peg arrays, the pegs are all in a 1/2 probability of falling to the fall to the left or to the right, and then hit the next layer of pegs, and so on, until they fall into the narrow slots in the bottom plate, thus obtaining a number of balls of the same size falling from the entrance, and as long as the number of balls is fairly large, it piles up in the bottom plate in a pattern that approximates a normal density function (i.e., high in the middle, low on the ends, and low in the) center). An ancient bell pattern with left-right symmetry, where N is the number of layers of nails.SpecificationName: Dalton Board/Galton BoardMaterial: Acrylic PlasticColor: Yellow Size: 40.5*30.5*3.5cm/16"*12"*1.5" inchProduct List:1* Galton board

• Statistical Tools: Galton board is a professional tool for analyzing the statistical distribution of molecular velocity and studying the model of random phenomena. It is used as a teaching tool to study the model of random phenomena, the law of statistical distribution and to explain the rate of motion of gas molecules.
• Premium Construction: Crafted from high-quality plexiglass, the Galton Board Desk Toy features durable components including a row of nails, V-shaped grooves, insert plates, and notches, ensuring longevity and resilience to regular use.
• Illustrative Statistical Distribution: Rotate the Galton Board to witness steel balls bouncing randomly, forming an approximate bell curve. This visual representation allows for easy observation and analysis of speed distribution, making it an ideal tool for studying statistical phenomena.
• Product Size: With dimensions of 40.5cmx30.5cm, this board is conveniently sized for tabletop use while still providing ample space to clearly illustrate the principles of randomness and distribution
• Application: Perfect for classroom demonstrations, educational displays, and physics enthusiasts.
