On April 3, Mr Rettig’s Physical Science class conducted an experiment using Rube Goldberg Machines. A Rube Goldberg Machine is a deliberately complex machine, used to complete a simple task in a series of steps. The class used the Rubes to help with the class’s Energy and Change Unit. The Rubes were designed to complete simple tasks, and the students were able to break down their Rube into each individual step. From there, the students went through each step and told all of the different energies required for each step to be performed.  The energy that was transferred from one step to another were also noted and all simple machines used through the Rube were identified. This experiment was a good way to help the students learn how energies are distributed throughout different steps in simple tasks.
