Overview

This honor requires youth to demonstrate understanding of mechanical engineering concepts through LEGO, build a reliable and original module, and collaborate in a larger working ball contraption display.

The Challenging Part

The most challenging requirement of this honor is probably this:

8. Participate in a GBC group activity that has at least 12 modules, with two or more builders. You must successfully pass one of six marker balls to the end of the circuit. It can be an actual GBC show, an event hosted by your local club or area, or a community event.
