Engineering Day - March 20, 2007

Once again, we will be hosting Engineering Day including spontaneous design activities, mouse trap car races and a machine design competition. There will be two levels of machine competition: Senior for high schools and Junior for 8th grade classes.

Competition will be held in the Walker Cisler Center on the campus of Lake Superior State University. Doors will open at 8 a.m. for set-up. Competition begins at 9 a.m.

Please register your teams by 5 p.m. on Friday, March 9.

Machine essays describing how the machine functions and the steps used must be submitted by 4 p.m. on Wednesday, March 14. They can either be mailed, e-mailed or faxed. See registration form for addresses and numbers.

Senior Division teams are limited to three per school and six "official" members per team, of which only two may come into contact with the machine during competiton. Medals and certificates are awarded to first through third place, ribbons for first through fourth, and a traveling trophy for first. Please see Competition Challenge for rule change.

Junior Division teams are also limited to three per school, eight members per team of which only two may come into contact with the machine during competition. Ribbons and certificates are awarded for first through fourth place and a trophy for first.

Mouse trap car teams are limited to two members. At this time, there is no limit to the number of teams. Ribbons are awarded to first through fourth for speed and distance, and a trophy to the combined first place winner.

We have set the date a month later than usual to encourage participation in events such as FIRST and still have the opportunity to attend Engineering Day. To register your team, please send an e-mail to:

Registration and Judging:

Following are downloadable Word documents. The judging form will help you see how your machine will be judged during competition.

The registration forms ask for t-shirt quantities and sizes. The department has chosen instead to give participants insulated lunch bags. We hope you will find our substituted item more useful and enjoyable.

Please note: The Rube Goldberg organization has made several changes this year, and there will not be a national competition until spring 2008 at Purdue University. The organization is focusing on increasing competitions at the local and regional levels. In addition, the organization has introduced a $300 per team fee, of which we were able to get the organization to waive $200. We believe it is in the best interest of our participating schools and the current economic climate of most Michigan school districts to encourage a competition based on creativity, developing teamwork and a positive experience versus fund-raising and potentially-increased levels of competition intensity. Therefore, this year we are holding our event "independent" of the official Rube Goldberg organization at no cost to our participants. However, we will use the challenge and rules devised by Rube Goldberg, Inc. in order to continue the consistency of past competitions.
