Famous Americans Visit Evangel The third-grade students at Evangel Christian Academy recently read biographies about famous Americans. After reading their books, each child dressed up to represent his or her character and shared the information they learned with the class. In attendance that day were Laura Ingalls Wilder who brought her lantern and books; Martin Luther King Jr. who brought his Nobel Peace Prize; Johnny Appleseed who brought his Bible and apples; and George Washington, who wore his favorite white wig. Also visiting that day were Daniel Boone, Buffalo Bill, Sacagawea, Mae Jemison, Helen Keller, Harriet Tubman and Rosa Parks.

Trinity Physics Students Test Spaghetti Bridges Physics students at Trinity Presbyterian School have been studying forces in one dimension and were assigned the task of designing and constructing truss bridges of nothing more than uncooked spaghetti and hot glue. To help them get started, they tested paper bridges and learned how arches, and particularly triangles, could provide so much more support force than an ordinary flat bridge. All the finished pasta bridges competed within dimensional perimeters and a constant bridge span. The bridges were tested with how many rolls of pennies they could support. The winning design was produced by engineering extraordinaire Daniel Green. His bridge had a mass of 215.39 grams and supported a whopping total 10,331 grams (10.3 kg, 22.8 lbs) -- that’s 48 times its own mass! The class ran out of rolls of pennies and had to resort to masses, fishing sinkers, and a science book before the bridge even began to crack. Other top contenders were Jacqueline Morris, whose bridge supported 40.5 times its own mass; Colton Bassett, whose bridge supported 36 times its own mass; and Stephen Neu, whose bridge supported 33 times its own mass. From left are Colton Bassett, Dalton Bopp and Daniel Green testing a bridge. Montgomery Parents I February 2013
