Register Open for Teams & Volunteers – 21Apr17 Trebuchet Egg Throw Competition

2017 Trebuchet Egg Throw Competition

The 9th Annual Trebuchet Egg Throw Contest will be held on Friday, April 21, 2017 at:
Bettendorf High School
3333 18th Street (football practice field south of track/football stadium)
Bettendorf, Iowa 

Bad Weather Plan:  We plan to hold the event event if it rains unless we encounter extreme conditions (rain all day, lighting or high winds).  If we decide to postpone for the entire day, we will send out an e-mail early on Friday morning and post on this event page.  If we need to reschedule, which is very unlikely, we will reschedule to Monday, April 24, 2017.

Last year, 25 teams from 5 area high schools participated.  The competition is part of the QC High School Tech Challenge.  High school teams and individuals received points from each of the 3 QC Tech Challenge events (Battle of Bridges Contest, Trebuchet Egg Throw Contest, and Cardboard Boat Race.  A traveling trophy is provided to the top high school and an award to the top scoring individual along with a scholarship.

Teams:  Teams will consist of a minimum of three students (recommend no more than eight) and one advisor. A student is someone who has not yet graduated from high school. An advisor may be a teacher, principal, parent, or guardian or anyone designated by the school that is an adult and willing to take on the challenge and responsibility.

Event Overview:  Teams design & build trebuchets to launch raw eggs at targets at three, specified distances 75, 100, and 125 feet. Each team will get four shots at each distance with the two best shots counted for scoring. This field competition will count for 60 of the total 100 possible points.

In addition to the trebuchet, a presentation worth up to 40 points is given by each team to local engineers from the QCESC. 

An optional stand-alone contest and team prize will be given for the trebuchet that launches an egg the longest distance with additional two eggs and launches allowed per team.
