The teams of teachers implemented the integrated STE(A)M learning scenario (LS) of their choice, created by another team and are now sharing their impressions and experiences with us. STORIES OF IMPLEMENTATION Welcome to the STE(A)M IT Community for the exchange of practices based on STEAM approaches! On this section, you can find the Stories of Implementation (SoI) provided by the Pilot Leading teachers."This method involved a fairly complex mathematical procedure (the extraction of a cube root) and seems to reflect the effort to apply geometry to an important engineering problem," he said. "At some point in the third century B.C., as a result of a process of intensive testing and experimentation fostered by the Alexandrian kings, a standard method for constructing these devices was developed," Schiefsky told LiveScience. The researchers found a distinct period in the ancient texts when the new ways of thinking were incorporated into catapult design, for example. When the mathematical theories were developed, construction became much more systematic, Schiefsky said. It was a simple case of necessity being the mother of invention, with things like meat needing to be weighed and some method required to do so, Schiefsky said.Īthenians also understood the mechanics behind a basic pulley system well before Archimedes came along and invented the compound pulley, which the Greeks famously used to hoist and topple enemy ships during battles at sea. The steelyard, which used unequal arms and weights to weigh items, was one device in use well before the advent of the math that explained it. “They didn’t all go to Plato’s Academy to learn geometry, and yet they were able to construct precisely calibrated devices,” Schiefsky said, adding that craftsmen combined some improvisational trial and error with years of practice to make their machines functional. Delving through technical books-such as instruction manuals-going as far back as the fifth century B.C., Schiefsky and a team from the Max Planck Institute for the History of Science, in Berlin discovered the ancients were, in fact, building the machines anyway. "These machines changed the course of history," Schiefsky said.īefore the mathematical models were figured out by Archimedes and his contemporaries, it was assumed that craftsmen didn't have enough theoretical knowledge to construct contraptions such as the catapult and scale balance, Schiefsky said. ![]()
