Students in Scott Dee's Physics class had to design and construct a paper bridge that would support the greatest weight possible.  The teams had to build the bridges using only paper and glue, staying within specific ranges for weight, height, width, and length.  Only standard 8.5 x 11" 20-lb. unlaminated paper could be used.  Above, students weigh and measure their bridges before they test their strength. 

After the weigh-in, each bridge was set up to span the gap between two of the science lab's tables.


The first team prepares to test their bridge's strength.
 Weight was added until the bridge collapsed or sagged to 90% of its original height.


The team reacts when their bridge suddenly reaches it's load limit.
