Straw Structures

Students were learning the Engineering and Design Process (or part of it) through building Straw Structures?

Materials:

  • 50 straws
  • 50 pipe cleaners
  • 25 paper clips

Objective:

Build the tallest free-standing structure possible that will hold a golf ball at the top, using the giving materials.

Constraints:

  • Must support the golf ball for at least 1 minute.
  • Must work with partners and make everyone feel included.
  • Must take apart the structure and clean up when finished.

Method and Timing:

  • 5 minute individual brainstorming time – students were to be working independently (quietly) in their science notebook, sketching or writing out notes to share with their group
  • 5 minute team planning time – share their ideas with their table partners, figure out a way to combine their plans, or use some of the ideas
  • 20 minute build time – making adjustments as they go

Reflect and Revise

  • The whole block of time was used for the planning and building. We have did not have time for the reflect and revise.
