Children arrange the pieces to end to end in descending order, causing marbles to roll down the slope on their own. Because of the small scale of the materials, this investigation requires patience, precision and promotes motor skill development. We’ve also discovered that as certain marbles travel and descend down the course, they make musical tones!
