Galton board: a bell curve from chance
Balls fall through rows of pegs and pile up in a bell shape. Hands-on probability and the normal distribution for kids 9+.
Interactive experiments for kids, students and teachers. Run each one right on the page, then open a copy in the Tymora editor and change mass, friction, elasticity or gravity. Every experiment comes with discussion questions and a version to try at home.
