Dalton Board/Galton Board, Effective Statistical Law Demonstration,Experiment Model for PhysicalSchool Laboratory Teaching Demonstration Teaching (Blue)

【Professional】Statistical tools that use gas molecules to explain the statistical regularity of velocity distributions. A teaching tool for studying models of stochastic phenomena, statistical distribution laws, and explaining the rate of motion of gas molecules. 【Principle】Rotate the Galton plate to start a stream of steel balls that bounce with equal probability,Watch as steel beads bounce with equal probability to the left or right, approximating the bell curve. A must-have addition to your laboratory supplies 【Application】Perfect for classroom demonstrations, educational displays, and physics enthusiasts. 【Size】Measuring 15.7" x 12", it's the ideal size for a desktop toy or a unique gift for physics lovers. 【Material durable】The instrument consists of a plexiglass plate, a row of nails, V-shaped grooves, insert plates, notches, etc.
