Luna's family is exploring some ancient ruins in Israel when they notice something very interesting, two stone arches that have somehow stayed in one piece over thousands of years. It gets them wondering, how do the rocks in the arch stay together like that? Why don't they fall? What's happening here? Educational Objective: Investigate how keystones allow stone/rock arches to stay in place and support heavy structures.
