6th Grade Computer

6th grade is working on the engineering design process.  They are using Bridge Builder, a CAD software program originated by West Point.  The students use the software to create and test a bridge that they themselves design. If the bridge fails then the student modifies it and retests it until it passes.  When the bridge passes the test, then the student has to work to lower the cost of the bridge by modifying it and still have it work.
