1. A hands-on engineering and teamwork challenge

2. 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

3. What is a simple machine? A machine with few or no moving parts. Simple machines make work easier.

22. Who was Rube Goldberg? Watch the man himself!!!

23. 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

24. What you will need Your responsibility: – Specific materials for your machine Provided: – “random materials” for your machine – Tools

25. TODAY You will form your groups You will “name” your group Create a rough draft of your logo Begin to brainstorm ideas
