The Paper Bridge

RICHARDTON HIGH SCHOOL TECHNOLOGY DEPARTMENT RICHARDTON, NORTH DAKOTA

THE PAPER BRIDGE

OBJECTIVE:

To learn the difference between potential and kinetic energy. To learn to use different forces of prime movers.

To learn the principles of forces like compression, torsion, strain, and shear.

To work independently or cooperatively. To learn to brainstorm (lens smashing) and develop problem solving skills. Make decisions using trial and error. Work within a given amount of time. Work with only materials given. Deal with competition with your peers.

PROBLEM:

Using a standard sheet of 8.5 x 11 sheet of paper and 10 cm of clear tape (approx. 4 inches), Construct a paper bridge that will span the greatest distance.

LIMITATIONS:

Time limits for construction is 30 minutes or instructor’s discretion.

No power tools will be used.

Exacto knife, scissors, paper cutter maybe used.

The paper bridge must be free standing (cannot be fastened to table, floor or buttresses).

All bridges must stand for 30 seconds during the testing time.

EVALUATION:

Students will test their own bridges.

The instructor will be the official timer.

20 points = Bridge with the longest span.

19 points = 90% of the longest span.

18 points = 85% of the longest span.

17 points = 80% of the longest span.

16 points = 70% of the longest span.

15 points = Bridge did not stay standing for 30 seconds
