Rube duffers will 'tee it up' in national contest

NOTE TO JOURNALISTS: Video and photographs of past contests are available. Journalists will not be allowed on the stage with the machines during the competition, but they are welcome on stage before and after the contest. Purdue will provide video and photo pool coverage and direct audio and video feeds. An ISDN line is available for radio interviews. Video b-roll, photos and a news release will be available the afternoon of the event. Satellite assistance is available.

WEST LAFAYETTE, Ind. -- College students from around the country will be crossing their eyes and dotting their tees at the 11th annual national Rube Goldberg Machine Contest on April 10.

The event honors the late cartoonist Rube Goldberg, who drew whimsical machines with complex mechanisms to perform simple tasks. Each year, college students are challenged to build actual functioning machines that Goldberg might have drawn. The task for 1999 is to tee up a golf ball. Previous contests have asked students to make a cup of coffee, put a stamp on an envelope and load a compact disc into a CD player and play it -- in 20 or more steps. The 1998 national competition drew teams from Texas, New York, Tennessee, Indiana and Wisconsin.

The contest, which is free and open to the public, will begin at 11 a.m. in Elliott Hall of Music on Purdue's West Lafayette campus.

Students will build their machines by combining the principles of physics and engineering with common objects such as ball bearings, mouse traps, wooden dowels, motorized toy vehicles, funnels and yards of duct tape. Each machine must run, be reset and run again in nine minutes. Points are deducted if students have to assist the machine once it's started. The teams also will be judged on the creative use of materials and use of related themes.

In addition to cash prizes for the top three teams, a "People's Choice" award will be given to the team whose machine gets the most votes from audience members.

The contest is organized by members of the Purdue chapter of Theta Tau, an engineering fraternity, with support from industrial sponsor BP Amoco. Contests for Purdue students were held from 1949 to 1955, and the fraternity revived the idea in 1983 to celebrate National Engineers' Week. The first national contest was held in 1988.

Purdue's entry was chosen in February at a local contest. The winning machine, built by the Purdue student chapter of the Society of Manufacturing Engineers, is based on the theme "Wide World of Sports" and includes a miniature downhill skier crashing in a spectacular fashion reminiscent of the opening of the ABC Sports program of the same name. It uses 55 complex steps and a variety of sporting goods to tee up the golf ball.

Last year's national contest was won by a team from the University of Texas at Austin, whose contraption used 40 mechanical, chemical and electrical steps to turn off an alarm clock.

Purdue hatches popular plans to egg on young scientists

WEST LAFAYETTE, Ind. -- For many kids, the first taste of farming may come in the classroom. A 4-H Classroom Chicken Embryology program in Lake County that started as a pilot project in two school corporations a decade ago is now in every school corporation in that county -- public and private -- and reaches about 10,000 students each year.

"It took off like wildfire," says Corinne Powell, a Lake County youth educator in the Purdue Cooperative Extension Service, who offers the program twice a year and trains teachers. "We're mainly an urban county, so many of our students don't have an opportunity to see live farm animals.

"It is our most popular 4-H classroom program, and it has opened doors for other 4-H programs in the schools." Teachers use the project to teach everything from life sciences to math, from reading to group cooperation.

For Mickey Latour, Purdue poultry specialist, visits to the classroom and thank-you letters from students are a big bonus. When Latour came to Purdue as Extension poultry specialist, his first thought was, "What can I do to serve the poultry production efforts in Indiana?"

One strategy was to formalize the loaning of incubators to schools into a curriculum-based program, which he christened "Incubators in the Classroom." During 1997-98 school year, incubators were placed in about 75 schools.

The incubators are delivered to classrooms for the last three days of the eggs' incubation. A story-line coloring book, teacher lesson plan and CD-ROM complete the curriculum.

Incubators in the Classroom has helped unite poultry promotion efforts throughout the state. The Indiana Turkey Marketing Council and the Indiana State Poultry Association have helped fund incubators (now up to 18), as well as curriculum materials and the CD-ROM, which Latour developed.

The first of its kind, the CD-ROM captures what happens inside the egg -- including a video clip of the embryo's beating heart -- before it hatches.

Because it required human intervention to complete its task, the SWE machine did not place among the top three. A team representing the Society of Manufacturing Engineers won the contest and will vie for the national title April 10 at Purdue. (Purdue News Service Photo by David Umberger)
