This engineering curriculum aligns to Next Generation Science Standards ( NGSS).Įngineers approach problem-solving in a variety of ways, including fully understanding of a problem, compiling knowledge of all possible variables, and applying their experience to find a solution. Expect that the bridges can resist at least 90% of their estimated strength and in case of failure, students have to determine the possible causes. Students consider their materials’ hypothetical costs and test their constructed bridges to verify load strength. Students perform the truss bridge strength estimation using a graphic interface that determine stress-compression on the truss elements using the method of joints. In this activity students design, construct, and test the strength of a wooden truss bridge and satisfy certain conditions like span, strength, and cost.
