No glue-no mortar. Structures so strong they've “held up” for over 1700 years. With this hands-on kit students learn how force vector analysis is used in architectural strength-just like the ancient Roman structures. Students first analyze the Roman arch, the caternary arch, and the corbeled arch. They then use the blocks provided to build a model Roman arch. How strong is the structure? You'll have fun testing its strength. How about a bridge-building contest?
Comes complete with blocks, detailed instructions, and historical perspectives.
