Paper Bridges STEM Challenge

This is an awesome STEM challenge for young kids and older ones too! Explore forces, and what makes a paper bridge strong. Fold that paper and test our your paper bridge designs. Which one will hold the most coins? We have tons more easy STEM activities for you to try! 

HOW TO MAKE A PAPER BRIDGE

WHAT MAKES A PAPER BRIDGE STRONG?

Beam, truss, arch, suspension… Bridges vary in their design, their length and how they balance two main forces, tension and compression. Tension is a pulling or stretching force which acts outward and compression is a pushing or squeezing force, acting inward.

The goal is that there is no overall force to cause motion and do damage. 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.

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. Learn more about what is engineering.

BUILD A STRONG PAPER BRIDGE

While you are at it, check out these other fun paper STEM challenges… Strong Paper, Paper Chain and Walking Through Paper.

SUPPLIES:

  • Books
  • Paper
  • Pennies (coins)

INSTRUCTIONS:

STEP 1: Place several books about 6 inches apart.

STEP 2: Fold the papers into different paper bridge designs.

STEP 3: Place the paper across the books like a bridge.

STEP 4: Test how strong your bridge is by adding pennies onto the bridge until it collapses.


STEP 5: Keep a record of how many pennies your bridge could hold before it collapsed! Which paper bridge design was the strongest?
