Outside-of-the-box STEM

Challenge students to unleash their imagination, grab a pile of junk, and design, test, and improve a machine that solves a simple problem.

“I needed a exciting way to teach students important STEM concepts and problem-solving.”

What is a Rube Goldberg Machine?

A Rube Goldberg Machine is a silly, over-the-top, wonderfully complicated invention that uses chain reaction to do a very simple job, like open a box, flip a switch, or pour a bowl of cereal. Learning isn’t a straight line, and neither are Rube Goldberg Machines. The Rube Goldberg iBlock is hands on project-based learning that turns trial-and-error into lessons in everything from core STEM concepts to creativity, collaboration, and perseverance.

Why purchase a Rube Goldberg Machine iBlock?

A Rube Goldberg Machine PBL (Project-Based Learning) iBlock helps you get from Point A to Point B with your invention. You’ll have everything you need to get going, from the learning content, consumables, and materials you’ll use to build your machine, to admission in the official contest.

Learn about the hands-on, skills-building, problem-solving fun that is building a Rube Goldberg Machine.

Rube Goldberg Books

The iBlock project-based learning content is a great way to support the creation of your machine, and all of the investigation, invention, and innovation that go along with it.

The iBlock guides your students through the Engineering Design Process, first building context and understanding around Rube Goldberg, simple machines, and how they come together in a Rube Goldberg Machine. Then, the content leads students through the planning, design, and construction of their machine. Finally, they’ll test and evaluate their machine, learning the importance of refining, remixing, and redesigning.

Each year, The Rube Goldberg Institute invites students around the world to design and build intentionally inefficient contraptions and compete at Regional Rube Goldberg Machine Contests. Educators can lead a team or host a contest, and every participating team earns an invitation to the World Championships at Purdue University, held each spring since 1988.

Students can compete in many ways – building physical machines, designing digital contraptions in Minecraft or Unreal Engine, or sketching their ideas in the Rube Goldberg Crazy Contraption Cartoon Contest, making it easy to engage learners of all ages and interests.

Want to see what it’s all about?

In our sample Rube Goldberg iBlock, students dive into STEM content as they experience the engineering design process first-hand. Their work culminates in the creation of their own chain reaction machine that pulls together their research, guides them through the design process, and fosters important skills like critical thinking and problem-solving.

Our approach encourages exploration, creativity, and design-thinking. We believe students learn best by doing.

Students lead the way while teachers guide and coach. There will be trial and error, testing and re-testing, and even the occasional dead end—but every obstacle becomes a springboard for new ideas, deeper understanding, and lasting success.
