Desk Galton Board for STEM learning Overview A compact, durable quincunx board that turns abstract probability concepts into visible experiments. Made from acrylic and PP with sturdy pegs, Vshaped grooves, and reinforced plates, this desktop Galton Board lets students and instructors observe real time ball trajectories and statistical patterns. Key benefits Visualizes probability and randomness so students grasp normal distribution without complex math. Durable construction for repeated classroom or lab use; components hold alignment for consistent results. Compact or classroomready sizes let you choose the right scale for individual study or group demonstrations. Encourages experimental reasoning, data collection, and basic data analysis through handson activity. Simple mechanical operation: rotate to release steel balls, watch them bounce through pegs, collect results in measurable bins. Features Quincunx design with strategically placed pegs guiding steel balls into a predictable bell curve. Vshaped grooves and reinforced plates ensure smooth ball movement and long term stability. Materials: acrylic body and PP components for clear visibility and impact resistance. Operates without power; mechanical rotation releases balls for repeated trials. Sizes Small size: 16 x 12 x 7.5 cm, compact for home study, desktop experiments, or smallgroup demos. Large size: 31 x 23 x 11 cm, suitable for classroom group observations and lab demonstrations. Package contents 1 Desk Galton Board corresponding to the selected size. Use scenarios Classroom demonstration: Show a whole class how repeated trials converge on a normal distribution while collecting and analyzing results. Physics or statistics lab: Use as a handson experiment to measure outcomes, calculate frequencies, and compare empirical distributions to theoretical predictions. Home or smallgroup learning: Conduct guided activities that introduce probability, randomness, and the concept of statistical variation. Additional notes Minor color differences may appear due to lighting in photos. Slight size variations can occur due to manual measurement.
