Service:If you have any questions, please contact us. We will respond within 24 hours!Specifications:This apparatus consists of a plexiglass plate, a row of nails, a V-shaped groove, an insert, and a narrow slot.Dimensions: Approximately 42 x 32 cmInstructions:Turning the apparatus upside down, pour all the balls into the V-shaped groove, insert the insert, and then flip the apparatus so that the V-shaped groove is at the top. Pull the insert to drop the balls. Collisions with the nail array will be randomly distributed, with nails equidistant on both sides, and each horizontal position on the previous layer exactly between two nails on the next layer. When a ball contacts a nail during its fall, it has a 50% chance of falling to the left or right, then hitting the next nail, and so on, until it lands in the narrow slot on the base plate. In this way, many balls of the same size will fall through the entrance. With a sufficient number of balls, they will accumulate on the base plate, forming a pattern that approximates a normal density function (high in the middle, low at the ends, and low in the middle). This is a symmetrical antique clock, where N is the number of layers of nails.Product List:1* Galton PlatePrecautions:This instrument is made of plexiglass. Handle with care and avoid impact. Store in a cool, dry place after use.Due to different measurement methods, the dimensions may vary by 2-3 cm.

• [Advantages] It's easy to operate, making it ideal for classroom demonstrations and educational displays. Its engaging educational features will captivate physics enthusiasts.
• [Experimental Model] This versatile classroom device combines theoretical teaching with hands-on experiments. Beyond textbook learning, it allows students to experience probability phenomena firsthand through experimental activities.
• [How to Use] This device intuitively demonstrates the statistical concept of normal distribution. When the Galton plate is rotated along its axis, the steel ball bounces left and right with equal probability, allowing for the observation and analysis of velocity distribution.
• [High-Quality Materials] The Galton plate is made of a plexiglass sheet, a row of nails, V-shaped grooves, inserts, and notches, making it suitable for everyday use.
• [Exquisite Decoration] Its compact and exquisite design combines educational value with aesthetic appeal, making it a unique gift for physics enthusiasts.
