Setup

Print or hand-copy the essential prompt for Da Vinci Bridge Engineering Challenge, then set out only paper, pencils, and the common or recycled items needed for one test. Use a tabletop representation whenever the original version mentions a room, specialized device, or digital tool; the learning comes from the decisions and evidence, not elaborate scenery.

Activity

  1. Study a diagram of da Vinci's self-supporting bridge and note how the beams interlock.
  2. Build the interlocking structure across a gap using only friction, no glue or string.
  3. Gradually add weight to the center and record the maximum load before collapse.
  4. Write a short reflection connecting the design to da Vinci's Renaissance engineering notebooks.

Done when: The group has completed Da Vinci Bridge Engineering Challenge when it can write a short reflection connecting the design to da Vinci's Renaissance engineering notebooks and point to the observation, measurement, comparison, or trial that supports its conclusion.

Materials

Wooden craft dowels or popsicle sticks, weights or books for load testing
