Reuben Goldberg was a cartoonist who imagined machines that perform a single job or task in a complex or indirect way. He became famous for including this type of machine, now known as a Rube Goldberg, in his cartoons. A Rube Goldberg device usually includes ten steps and has a device that generates a chain reaction. Implementing Rube Goldberg activities in the classroom encourages your children to develop scientific and analytical skills.
Design a Rube Goldberg Device
Prepare a list of simple daily tasks for your students. Examples include turning on a computer, pouring water and rolling a ball across the floor. Divide students into groups and present each group with a task. Give each group time to brainstorm an appropriate Rube Goldberg device or machine that could be made to achieve the task. You can set the number of steps that are necessary for each machine. Have each group present their results to the classroom after an allotted time.
Analyze Rube Goldberg Cartoons
Rube Goldberg cartoons are stand-alone images that interest children because of the complexity of the task depicted. Divide your students into groups and present each group with one of Rube Goldberg's cartoons. Remove each cartoon's caption before distributing them. Each group must try to identify all of the steps involved in achieving the task in the cartoon. You can set up a contest-like atmosphere in your classroom where the group with the closest number of correct steps wins a prize.
Preparing to Make a Rube Goldberg Device
Children love hands-on activities and they'll have a blast trying to make a Rube Goldberg machine. Hand out sample cartoons of Rube Goldberg machines for students to observe, and in groups encourage them to brainstorm Rube Goldberg devices. Provide them with drawing materials with which to depict their ideas. Have them start by creating a plan or blueprint for their machine. They should identify the task they're trying to achieve and list all of the steps involved in achieving the task.
Making a Rube Goldberg Device
Students can use different types of papers and containers to create their contraption. Make sure there's plenty of glue and tape available with which students can put all the parts together. Remind students that their machine doesn't necessarily have to function; they just need to be able to explain how their Rube Goldberg machine should work in real life. At the end of the project period, have each group present their work to the class.
