This instrument is a teaching instrument based on the new high school textbooks, using the model designed by British biologist Dalton to study random phenomena, to illustrate the statistical regularity of the distribution of gas molecule motion rate.

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.

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.

Perfect for classroom demonstrations, educational displays, and physics enthusiasts.

Measuring 15.7" x 12", it's the ideal size for a desktop toy or a unique gift for physics lovers.

The instrument consists of a plexiglass plate, a row of nails, V-shaped grooves, insert plates, notches, etc.

Structure

This instrument is composed of plexiglass, array nails, V-grooves, plug plates, narrow slots, etc.

How to use

Invert the instrument, pour all the balls into the V-shaped groove, insert the plug, then flip it so that the V-shaped groove is on the top of the instrument, pull out the plug, and the balls fall down, collide with the nail array and scatter randomly. The distance between the nails is equal left and right, up and down, and each ball in the upper layer is exactly in the middle of the two balls in the lower layer. When the ball hits a nail during the fall, it falls to the left or right with a probability of 1/2, and then hits the next layer of nails, and continues like this until it falls into the narrow groove of the bottom plate. Drop many balls of the same size from the entrance. As long as the number of balls is large enough, it will pile up on the bottom plate into a density function graph that is close to the normal (that is, high in the middle, low at both ends, and symmetrical in the shape of an ancient bell), where n is the number of layers of nails,
