![]() The school would like the new bridge to blend into the community, but also be short so as to reduce cost. Therefore, the bridge must be able to withstand extreme weather temperatures, as well as the many feet of snow and wind gusts from winter blizzards. Winters in Minnesota are extremely cold, and summers can be quite warm. You will design and present these prototype bridge designs in order to "sell" your plans to the clients.Ī school in Minnesota needs a foot bridge to provide its students, teachers and visitors a faster, more comfortable way across a small stream on campus. Your engineering team has three missions to complete. (Depending on the level of students, provide students with specific bridge designs for each scenario, or direct students to begin without any plan, as a more open-ended challenge.) In today's activity, you will be acting as engineers and be given scenarios that require you to come up with the best bridge design for each. When this problem occurs, civil engineers must find a way to safely cross the obstacle according to specifications provided by the town or state. ![]() Sometimes such a path is impossible to find, especially if a long river, large lake, or deep valley is in the region. When engineers are building a new road they try to pick a route with the fewest number of huge obstacles. Teacher Rubric for Bridge Activity (pdf) Visit [ to print or download. Refine design solutions to address criteria and constraints.Ĭreate solutions to problems by identifying and applying human factors in design.Ĭritue whether existing and proposed technologies use resources sustainably. The selection of designs for structures is based on factors such as building laws and codes, style, convenience, cost, climate, and function.īuildings generally contain a variety of subsystems.ĭevelop innovative products and systems that solve problems and extend capabilities based on individual or collective needs and wants.Īnalyze how an invention or innovation was influenced by its historical context. Make two-dimensional and three-dimensional representations of the designed solution. Requirements for design are made up of criteria and constraints.īrainstorming is a group problem-solving design process in which each person in the group presents his or her ideas in an open forum. International Technology and Engineering Educators Association - Technology There are systematic processes for evaluating solutions with respect to how well they meet the criteria and constraints of a problem.Īlignment agreement: Thanks for your feedback! Sometimes parts of different solutions can be combined to create a solution that is better than any of its predecessors.Īlignment agreement: Thanks for your feedback! Although one design may not perform the best across all tests, identifying the characteristics of the design that performed the best in each test can provide useful information for the redesign process-that is, some of the characteristics may be incorporated into the new design. This activity focuses on the following Three Dimensional Learning aspects of NGSS:Īnalyze and interpret data to determine similarities and differences in findings.Īlignment agreement: Thanks for your feedback! Practice building techniques that civil engineers use.Īnalyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.Ĭlick to view other curriculum aligned to this Performance Expectation.Observe quantitatively how bridges work under load and why engineers use different types of bridges for different places.These engineers must consider many variables when creating plans, such as distance to be spanned, where the bridge is being built (physical terrain), what type of traffic (and other loads) it must carry, materials available, budget, and what the bridge will look like.Īfter this activity, students should be able to: Civil engineers are responsible for design and construction of such structures, and they work with mechanical engineers and material engineers to design the most stable structures possible for given project restraints. Many people in different branches of engineering work to build bridges. Copyright © 2007 Brocken Inaglory, Wikimedia Commons CC BY-SA 3.0
