This resource focuses on Leo's Bridge Building Challenge, where students engage with the design and structural components of a bridge model. Participants are prompted to closely examine the visual of a Warren Truss Bridge and identify three distinct parts or components of the structure. Subsequently, they are encouraged to discuss with a partner how these components contribute to the bridge's stability and the implications of a missing part in the overall design. This activity combines observation, critical thinking, and collaboration to deepen understanding of engineering concepts related to bridge construction.
