Simple machines

rube goldberg

We have been studying simple machines in class. Yesterday we learned how an inclined plane can make work easier and today we will be studying pulleys. This is a Rube Goldberg machine game that uses simple machines. What’s a Rube Goldberg machine?

A Rube Goldberg machine, contraption, invention, device, or apparatus is a deliberately over-engineered or overdone machine that performs a very simple task in a very complicated fashion, usually including a chain reaction. The expression is named after American cartoonist and inventor Rube Goldberg (1883–1970).  Mousetrap is an example of a Rube Goldberg machine.

Here is a fun game that uses a Rube Goldberg as a security system:

Here’s a harder one if that was too easy for you!  It uses a Rube Goldberg to bring you lunch:
