Rube Goldberg Machines - Grade 9

The  Grade 9s have been working on an Interdisciplinary Unit  (IDU) this term, Science and Design.  We covered Newton's Laws in Science and in Design they used these to design a Rube- Goldberg Machine (a contrapation to complete a simple task in a complicated manner).  Today the nachines were presented and there were some great machines - one with a Star Wars theme, another with a social media theme  and two with a bathroom theme - to put toothpaste on a tooth brush.

Here are some of my wonderul Grade 9 boys - Maxime, Harren and EJ with their multi stage contraption ready to put toothpaste on a brush via a vice triggered by a series of balls running down ramps and up pulleys.
