All the while, students watched, analyzed and predicted how the bridges would perform.<\/p>\n<p>On Dec. 15, the winning bridge withstood a student being placed in the test bucket and 10 lb. sandbags being added to get to 497 lbs. It was constructed with popsicle sticks and glue, weighed 1.1 lbs. and covered a 14-inch span, per Mr. Grossmann, who has taught at the school for five years. He underscored that the winning bridge ended up holding more than 400 times its weight.<\/p>\n<p>The process leading up to the competition saw the students learning about civil engineering by experimenting with various forces, i.e., tension, compression and bending, and then testing different materials, including popsicle sticks, straws and string, to determine which materials were stronger or weaker, per the school.<\/p>\n<p>Throughout the process, students also researched five different types of bridges \u2014 including arch, beam, cable-stayed, suspension and truss \u2014 and discussed local bridges and why each was designed and constructed in a particular way.<\/p>\n<p>Mr. Grossmann said that as an engineering major in college, he learned the most from classes where he built things and competed against other teams. He said his students \u201cshow that same creativity and problem-solving, which I believe is strong preparation for whatever they do after high school.\u201d<\/p>\n<p>Founded in 2002, Leadership Public Schools operates charter high schools in Richmond, Oakland and Hayward and serves more than 1,700 scholars annually.
