Build Your Own STEM Adventure – Rube Goldberg machines

Ideas for integrated STEM projects that align to the ACARA science understandings.

 

Rube Goldberg Machines

ACARA Science Alignment: Physical Sciences- Energy appears in different forms, including movement (kinetic energy), heat and potential energy, and energy transformations and transfers cause change within systems (ACSSU155 – Scootle )

Suggested Year Level: Year 8

Project: Students work in groups to design, construct, and test complex machines of multiple (at least 7) steps that perform a simple task (e.g. pop a balloon), using the engineering design model. They identify and use at least 3 forms of energy (e.g. kinetic, gravitational potential, sound) and identify each energy changes (transfer or transformation) that make the machine work.

Hook

Hook: Watch the film clip to OK Go’s song, ‘This too shall pass’ for a giant Rube Goldberg machine (https://www.youtube.com/watch?v=qybUFnY7Y8w)

STEM links: boost the connections with different disciplines by

· Maths – have students record the time of the machine at each stage/step and the distance and calculate the speed of movement of each step.

· Science – have students plan for and identify within their machine multiple forms of energy and energy changes.

· Engineering – have students construct the machine using everyday materials found around the school and home

· Technology – have students use technology to measure speed (timers, sensor gates) and film/document the process of building and/or performance of the final working machine (cameras, phone, editing software)

· Music/Media – have students film the performance of the final working machine and create music to accompany recording.
