Paper Beam Project

Materials and Equipment
1- 8 1/2" X 14" Piece of paper
White glue
Scissors or exacto knife

Background
Beams are used to form the skeletons for many types of structures (i.e. bridges, skyscrapers, towers, etc.). The size and weight of these beams is not nearly as important as their load carrying capacities. With proper design, even lightweight materials may sometimes be fabricated to produce beams with considerable strength.

Problem
Working in a group of two or three students and using the piece of paper supplied, design and construct a beam that will span an eight inch (8") space with one-half inch (1/2") of bearing surface on each end. Your group’s beam should support as much weight as possible.

Objectives
Demonstrate problem-solving skills.
Perform research on beam design (shapes, materials, etc.).
Apply math and science skills during technological activities.
Construct a beam using lightweight materials.
Practice Cadkey skills by drawing the beam design.

Limitations
Only white glue (Elmers) may be used.
No laminating is permitted.
No pins, reinforcing rods, paper clips, etc. may remain in your completed beam after the glue dries.
Use only the materials supplied to complete the project.

Notes
Here are some things to think about during testing.
Which beam design supported the most weight in your class?
Why did some designs function better than others did?
What does this activity suggest regarding the use of lightweight material in actual construction?
