With the Catenary Arch Model for physical science and physics, construct the catenary arch from the provided blocks and template to see firsthand the strength and stability of this type of arch and where it may be useful—like St. Louis.
Where does the St. Louis Gateway Arch get its unusual shape? The shape is the same as the natural shape of a sagging chain held at both ends—also known as a catenary. Students construct the catenary arch from the template and provided blocks to see firsthand the strength and stability of this type of arch and where it might be useful. A perfect companion to the Roman Arch Set (AP4628). Comes complete with detailed instructions and historical background.
