Weekly All School Bulletin
A unique melding of new and old technology took place on campus recently. The two Geometry classes spent several days last week in groups wandering around the campus acting as surveyors with a very high-tech device (their iPad) and a very low-tech device (a straw) attached to the top of it.
They were using an app on their iPads which turned them into "inclinometers" (which measure angles) with the straw as their viewfinder, along with another low-tech device (a tape measure), to determine "angles of elevation" or "angles of depression." Their task then was to use basic trigonometric ratios to find the height of a number of things on campus, such as St. Margaret's Hall or our beautiful Copper Beech tree below the South Porch.
After gathering their data, each group created a packet of tables and drawings to illustrate their use of trigonometry to better understand how mathematics is used every day in the "real-world."
