Purpose

Students will engage in a hands-on project to design and construct a model bridge, applying the Triangle Sum Theorem to ensure it supports weight effectively. Throughout the project, students will collaborate, receive feedback, and reflect on their learning process, fostering self-directed learning and critical thinking. By connecting mathematical concepts with real-world engineering challenges, students will deepen their understanding of geometry and develop a sense of identity and belonging within the learning community.

Learning goals

Students will explore the application of the Triangle Sum Theorem in real-world engineering by designing and constructing a model bridge, focusing on the structural integrity and weight support. They will engage in self-directed learning by using feedback and reflection to refine their designs, fostering a deeper understanding of their learning process. Through collaborative problem-solving, students will develop critical thinking skills as they consider innovative approaches to bridge design, establishing a sense of identity and belonging within the learning community.
Competencies
  • Self Directed Learning - Students use teacher and peer feedback and self-reflection to monitor and direct their own learning while building self knowledge both in and out of the classroom.
  • Academic Mindset - Students establish a sense of place, identity, and belonging to increase self-efficacy while engaging in critical reflection and action.
  • Critical Thinking & Problem Solving - Students consider a variety of innovative approaches to address and understand complex questions that are authentic and important to their communities.

Products

Students will collaboratively design and construct a model bridge using either the Pratt truss or Warren truss design, applying the Triangle Sum Theorem to ensure structural integrity. Throughout the project, they will document their process, including sketches, calculations, and reflections on their learning journey. By the end of the week, each group will present their bridge model, supported by a written report that details their design choices, problem-solving strategies, and how they addressed feedback to refine their work.

Launch

Begin the project by visiting a local bridge or examining detailed images and videos of famous bridges, focusing on their design and structural elements. Facilitate a discussion on the role of geometry in bridge construction, emphasizing the importance of angles and weight distribution. Introduce the Triangle Sum Theorem and challenge students to consider how it might be applied in designing a bridge that balances aesthetics with functionality. Encourage students to brainstorm and sketch initial ideas for their bridge designs, fostering a sense of curiosity and engagement from the outset.

Exhibition

Students will showcase their bridge models in a classroom exhibition, inviting peers, teachers, and community members to observe and evaluate their designs. Each group will present their bridge, explaining how they applied the Triangle Sum Theorem and addressed structural integrity to support weight. Attendees will have the opportunity to ask questions and provide feedback, fostering a collaborative learning environment. The exhibition will conclude with a reflection session where students discuss their learning journey, challenges faced, and how they overcame them.
