| Description | Students are given the (hypothetical) engineering challenge to design and test a new composite material (one made from two or more materials bonded together) for use as the webbing for lawn chairs. Acting as engineers, students design and test strips of plastic chair webbing, learning about composite materials and tension as a force that acts on structural components and experiencing the engineering design/test/redesign process. Students are given the (hypothetical) engineering challenge to design and test a new composite material (one made from two or more materials bonded together) for use as the webbing for lawn chairs. They use thin plastic sheeting, masking tape, string and hot glue, aiming to achieve a design that holds the greatest possible load in tension with the least amount of stretch. Acting as engineers, students design and test strips of plastic chair webbing, learning about composite materials and tension as a force that acts on structural components and experiencing the engineering design/test/redesign process. |
