Description: Description Description&Previewshipping&policyDescription:Specification NameGalton board, effective demonstration of statistical laws Material: acrylic Plastic Color: yellow white red Size: 40.5*30.5*3.5cm/16"*12"*1.5" inch Description 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. Demonstrate the statistical distribution: By rotating the Galton board, the steel ball bounces randomly, forming an approximate bell-shaped curve, which allows you to observe and analyze the velocity distribution. Easy to use and educate: The Galton board is easy to operate and suitable for classroom demonstrations, educational displays and appealing to physics enthusiasts. PREMIUM QUALITY MATERIALS: Made of plexiglass panels, rows of pegs, V-shaped grooves, inserts and notches, the Dalton board is durable and designed to withstand regular use. UNIQUE TEACHING GIFT: Its compact size makes the Galton Board an ideal addition to any desktop and a unique gift for physics enthusiasts. 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. Product List: 1* Galton board Preview: Thank you for your purchaseProblems?
