Some Earth Day events involve volunteer clean-ups, planting flower beds or unplugging your gadgets for a day. The Technion-Israel Institute of Technology, however, challenged high school students worldwide to build an Earth Day-themed Rube Goldberg Machine—and three schools came through with flying colors (all shades of green, of course).
For the uninitiated, a Rube Goldberg Machine is a wacky contraption that is deliberately over-engineered to perform a simple task by setting off a comical chain reaction. Katz Yeshiva High School of South Florida (whose team of students ranged from 9th through 11th grades), placed first in this fun but difficult challenge, winning a one-year full scholarship to the Technion.
“When I saw our school’s name appear on the screen, I was overcome with emotions of comradery and school spirit. Tens of hours of hard work had finally paid off,” said 11th grader Tani Loskove. Teammate Ty Kay added: “As a high schooler pursuing dreams of becoming an engineer, Technion’s Rube Goldberg Earth Day Challenge was a great stepping stone for me. It was my first real engineering ‘project,’ and it taught me about teamwork, advanced preparation and the differences between theoretical and applied sciences.” Other students include: Noah and Joshua Bernten, Michal Amar and Max Davis.
Working out of a student’s garage, the winning team concocted a nearly one-minute chain reaction in which Coca Cola bottles activated a toy car, sent a ball down a winding slide worthy of a Water Park, releasing liquid gallium to complete a circuit, which eventually set off a stream of water that spun a home-built Ferris wheel, knocked down popcorn boxes that activated a fan—illustrating recycling (plastic, metal and paper) and alternative energy sources (hydro, solar and wind power).
Some 24 high school teams around the world participated in the challenge. A team of judges led by Prof. Alon Wolf, Director of the Biorobotics and Biomechanics Lab at the Technion’s Faculty of Mechanical Engineering, selected the winners based both on their creative renditions of Earth Day themes and the complexity of the energy transfers from one action to the next. Le Hong Phong High School for the Gifted in Ho Chi Minh City, Vietnam placed second, while the International Bilingual School at Hsinchu-Science-Park in Taiwan came in third.

“It’s very exciting for us,” says Dr. Yosef Wolf, who heads up Katz Yeshiva’s STEM courses and started a robotics club at the school. “It’s the first engineering contest that we have ever entered, and we came in 1st place! We’ve been growing our engineering opportunities recently and we have plans to further expand our STEM offerings next year. This result has further helped to increase our students’ excitement of the upcoming initiatives.”
Note: the contest is not over yet! May 1st is the deadline for the Most Popular Clip Contest. Winners will be announced May 3rd.
