Turn abstract probability and physics concepts into handson lessons with this Galton Board Probability Demonstration Model. Designed for educators and homeschool parents, it makes normal distribution and randomness visible and engaging for students aged 14 and over under appropriate supervision. Key benefits Visual learning made concrete: 3000 or 17500 steel beads cascade through precisionarranged pegs to form a clear bell curve, helping students observe normal distribution and the central limit theorem in real time. Ready for class in seconds: arrives fully assembled so demonstrations can begin immediately with no setup. Built to last: reinforced polypropylene frame, rustresistant stainless steel pegs, and Vshaped grooves minimize jamming and wear for repeated classroom use. Flexible sizing: compact 6.7inch model fits individual desks and homeschool tables; larger 12inch model improves visibility for lecture halls, university labs, or STEM centers. Features and specifications Educational focus: ideal for middle school, school, and homeschool STEM curricula, labs, and workshops. Materials: reinforced PP frame, rustresistant stainless steel pegs, Vshaped grooves for smooth bead flow. Size options: 6.7inch model: 12 x 7 x 17 cm (4.72 x 2.9 x 6.7 in), 350 g, 3000 steel beads preloaded. 12inch model: 23 x 11 x 30.5 cm (9 x 4.3 x 12 in), 600 g, 17500 steel beads preloaded. Age guidance: intended for use by individuals aged 14 and over under appropriate supervision. Includes: 1 Galton Board and 1 English instruction manual. Practical use scenarios Classroom demonstration: Show a full lecture how random events produce a normal distribution by releasing beads and recording outcomes for discussion and analysis. Handson lab activity: Small groups collect bead distribution data, calculate mean and variance, and compare experimental results to theoretical predictions. Homeschool or science fair: Use the compact model on a desk for oneonone teaching, experiments, or an interactive science fair display that invites student participation.
