Bridge Building

Engineers design and build bridges to solve various transportation problems. In this bridge building unit, students at Ashford School will step into the shoes of bridge building engineers to learn what it takes to successfully design, build, test, and redesign a model popsicle stick bridge.


Assignments for 3/21/12 to 4/11/12:

3/21 - 3/23: Explore the basics of bridge building--tension, compression, and reaction forces, handling the load, choosing the appropriate bridge types for different transportation challenges.

Tasks:

  1. Click on Nova Super Bridges link (Nova Super Bridges) and complete Build a Bridge activity.
  2. Reinforce your learning by reading the end-of-the-book interdisciplinary unit at the end of the Prentice Hall Motion, Forces, and Energy book.
  3. Download "Bridge Type" worksheet in the attachments below. Complete worksheet and email completed worksheet by 3/23/12 to Mrs. Perkins at: aperkins@ashfordct.org.
  4. In groups of 2-3 students, follow the instructions on the Bridge Building Engineering Challenge (see below, as attachment), to start your quest to build the popsicle stick bridge with the highest efficiency ratio. Completed bridge "stories" should also be emailed to: aperkins@ashfordct.org.

3/21 to 4/11: Your design challenge continues until you have gone three times around the engineering design cycle. You will use iMovie to record and analyze your bridge stress test. Using iMovie will help you slow down the action, replay the action in reverse, and create still images to analyze your bridge test more effectively.

Extra credit task: Complete a poster describing a famous bridge success or failure.
This opportunity is only available when the other tasks in the Bridge Unit have been completed. See Mrs. Perkins for details.
