A hands-on engineering and teamwork challenge
What is an RG Machine? A compound machine – Many simple machines connected together The definition of a Rube Goldberg Machine is: a compound machine that accomplishes by complex means what could be done simply
What is a simple machine? A machine with few or no moving parts. Simple machines make work easier.
Examples of Simple Machines – Lever – Pulley – Gear – Wedge – Wheel & axle – Screw – Spring – Inclined Plane

Who was Rube Goldberg? Watch the man himself!!!
Project objectives You will form small groups to design, build, and test a small scale Rube Goldberg Machine You will examine the vocabulary associated with simple and compound machines You will examine the mathematical formulas associated with the physics of simple and compound machines Your group will present and test your machine
What you will need Your responsibility: – Specific materials for your machine Provided: – “random materials” for your machine – Tools
TODAY You will form your groups You will “name” your group Create a rough draft of your logo Begin to brainstorm ideas
