Friendly Competition Produces “Eggcelent Results

On Thursday, May 30th, UConn’s GK-12 program hosted the second annual Engineering Design Challenge Competition, involving student teams from Connecticut’s Technical High School System, at the Storrs campus.  The theme of this year’s competition was “Reverse Engineering Egg Crash Car.” View photos here.

In the good-natured competition, the student teams were required to apply core engineering principles in a deceptively simple, fun and engaging way while pitting their engineering knowhow against that of other Tech School students.  The participating teams were the top performers in contests held at their home Tech Schools. 

In the Egg Crash Car competition, the teams were charged with building a racecar – using only the materials provided – capable of safely transporting an uncooked egg through a variety of challenges without the precious cargo breaking.

Among the materials available were Ziplock® bags, wheels, balloons, straws, pom-poms, mouse traps, fishing line, tape, poly-fill stuffing, cotton balls and rubber bands. These raw materials produced a variety of vehicles, from sleeeggcar1ak rectangular entries to zany-looking “Mad Max” style vehicles adorned with cotton-ball armor. For each vehicle, it was stipulated that the egg “passenger” had to be removable.

The GK-12 Fellows designed three rigorous tests for the vehicles: a rear impact test, in which a suspended wooden mallet was released from three different angles into the rear of the vehicle; a rollover test, in which vehicles were released at different angles from the top of a four-foot plane; and a head-on collision test, in which CO2 canisters were attached to the rear of each vehicle as a propulsion system that carried the vehicles into a cinderblock wall. For each test, the aim was to keep the vehicle and its egg cargo intact. Other criteria included the vehicle production costs, speed and structural integrity.eggcar1

In the end, the Tech School students enjoyed a fun day of friendly competition and came away with a better appreciation of core engineering concepts such as performance-based testing, tradeoffs between material cost and quality and the iterative and challenging nature of the design process.

The competition brought together teams from the Academy of Engineering and Green Technology, Howell Cheney Technical High School, Harvard H. Ellis Technical High School, E.C. Goodwin Technical High School, Ella T. Grasso Southeastern Technical High School, Norwich Technical High School, A.I. Prince Technical High School, Vinal Technical High School, and Windham Technical High School.

The teams – along with fellow students who did not compete – were mentored throughout the 2012-13 academic year by UConn Engineering doctoral candidates who are committed to helping introduce engineering concepts in Tech School classrooms. The 2012-13 GK-12 Fellows included Juan Pablo Correa Baena (Environmental Engineering); Lu Han,  Andrea Kadilak, Joseph Parisi and Rebecca Rubinstein (all in Chemical Engineering); Justin Roller and Michael Zilm (Materials Science & Engineering); and Lou Bachenheimer and Nick Curtis (Mechanical Engineering).

The GK-12 (Graduate STEM Fellows in K-12 Education) program is an innovative educational program sponsored by the National Science Foundation.  It aims to provide teaching resources (in the form of graduate students in the engineering sciences) to classrooms in the state of Connecticut Technical High School System.
