Bridges Contest Day
We are building bridges!  Each of our construction companies had a budget of $1,550,000 to construct a bridge that has a strict set of conditions that it must meet.  They designed the bridge on plan paper, wrote supply orders and checks and kept construction records.  This group is the first to finish.

 

 

 

 

 

 

 

 

 

 

 Mrs.Cochran is doing the stress test for one of our bridges. This bridge is holding 15 bottles of glue, 3 staplers and a large 3-hole puncher. Score is 10/10!
Here the design test successful; both the boat and the truck can travel under and over the bridge respectively.
This bridge strains against the weighted bucket attached below it.
Here is the set up for the strength test.
