The Challenge

 Attention aspiring engineers! The state of

Michigan needs your help. The Mackinaw

Bridge is beginning to deteriorate and a new bridge must be built. Governor Granholm wants the most qualified team of builders to oversee the design and construction of the new bridge.

Governor Granholm has issued a challenge to find the best bridge designers this country has to offer.

The Problem

 You and a partner must make a bridge out of popsicle sticks and glue.

 The bridge must be able to span a 16 inch gap.

 The bridge must be able to hold the most amount of weight possible.

6. Popsicle sticks can overlap up to 2 ¼ inches.

Rubric

 The bridges will be graded using a rubric.

Testing

 Bridges will be tested until failure.

 Each bridge will be loaded at the center using a chain and weight system or bridge tester depending on the semester

 The bridge must be able to accommodate the testing apparatus.

Grading Items

 1. Most weight held

 2. Most efficient bridge

 3. Most aesthetically appealing bridge

Schedule

 Time is of the essence!

 Your group must fill out a daily log (every day) to keep on track.
