The 2014 Inter-Chapter Challenge

UC Merced at the 2012 ICCThe second Inter-Chapter Challenge (ICC) will be held at the 2014 ESW-National Conference, to be hosted at Northwestern University on April 10th-13th, 2014. Participating chapters will build an inexpensive device that will be judged based on design & construction, function, and completion of several trials. The theme for this year’s ICC is boats. Unlike the previous year, there are no restrictions on power source aside from the avoidance of fossil fuel as a requirement.

Since we will be in a Great Lakes State on a university campus surrounded by bodies of water, we felt it would make sense to have this year’s Inter-Chapter Challenge involve building a boat—even a radio controlled boat! If you are planning on participating in this year’s ICC, please email Chapter Relations Coordinator Chris Thai at cthai@eswusa.org or tweet us @eswusa when you register for the conference.
