Marble Run Challenge

This week we started a new challenge on our Lego Wall.  The challenge: Can we build a marble run that actually works? Students in grades 1-6 have contributed to the marble run so far, and are learning what works and what doesn’t work. The biggest challenge they’ve run into is keeping the marble from falling off the wall. So far they have tried making barricades to keep the marble on track and special “covers” of Legos.  Here’s grade three at work at the end of our library class today.
