What is the science behind the paper bridge challenge?

A single piece of paper between two stacks of books falls down under its own weight. The answer lies in folding the paper to change its cross section (the shape you see when you look at the paper edge-on).

What is the strongest shape for a paper bridge?

use cylinder or sphere shapes — or both. The triangle is the strongest to as it holds it shape and has a base which is very strong a also has a strong support. The triangle is common in all sorts of building supports and trusses. The overall shape of many bridges is in the shape of a catenary curve.

Why does a paper bridge work?

A bridge uses tension and compression to balance itself and keep it standing. These two opposing forces work together to create an equilibrium in a bridge’s structure. A bridge will buckle if compression, the force pushing down on it, becomes too much; it will snap if tension, the force pulling on it, overwhelms.

Does folding paper make it stronger?

In this activity, students experiment with a variety of shapes such as folded corrugations and rolled tubes that can make an inherently weak material such as paper much stronger. By folding or rolling the paper, you create a “thickness” which allows the paper to reinforce itself and not collapse so easily.

Can your bridge hold 100 pennies?

Can you build a bridge that holds 100 pennies, using 1 sheet of paper and up to 5 paper clips? A bridge must support its own weight (the dead load) as well as the weight of anything placed on it, like the pennies (the live load). Your paper bridge must span 20 centimeters (about 8 in.).

When a bridge is made on paper it is done using?

Line up two pieces of paper end to end, so the short edges are overlapping just slightly (by about a quarter of an inch). Use long strips of Scotch tape to bind the pieces of paper together on both sides. These two pieces of paper will make one “bridge.”

How do you make a piece of paper stronger?

All you need to do is brush a thin layer of Mod Podge on your paper and let it dry. Flip over your paper and repeat the process. Mod Podge does take longer to dry than any other method.

Is crumpled paper heavier?

As weight is product of mass and acceleration due to gravity. And gravity is inversely proportional to the square of distance from the center of earth. So the force on the folded layers would be less. So unfolded paper would be more heavy then folded one.

When a bridge drawing is made on paper is done using?

What to do with stem Paper Bridge Challenge?

Have them record their strategies. Give them a day to obtain needed materials. Use the “Build a Bridge” and “Building Stronger Bridges” Augmented triggers and have students explore different ways they could use the materials needed to design their bridge.

Is it possible to test a Paper Bridge?

Depending on the purpose of the bridge, how much weight it will need to hold, and the distance it needs to cover, engineers can figure out which bridge is the best bridge. Take up the challenge and test your paper bridge designs.

How to build a bridge using one sheet of paper?

Explain that now the students will work in pairs to build a bridge using one sheet of paper. Their goal is to design a bridge that can hold as many pennies as possible. They will get multiple sheets of paper so they can test more than one bridge design.

How can students record data on paper bridges?

Students can also record their data in a journal or spreadsheet. Using the 360 & 3D Augmented Triggers have students explore bridges. Ask students to write down their observations. What materials do you think went into making these bridges?
