PRODUCT DETAILS
A great hands-on lab for physical science. This set of hardwood blocks is precision-cut in the shape of a catenary arch. It needs no support because it is the ideal shape to hold its own weight. The forces acting on the arch cause it to take the shape of a curve naturally. Set of 13, precision-cut hardwood blocks (each approximately 2" L x 1/2"-1" thick); full-size template; and instructions. Grade 4 and up.
