1. Rube Goldberg Machine

2. Rube Goldberg Machine
A contraption, invention, device, or apparatus that is purposefully made complicated to perform a simple task, it generally including chain reactions.

3. Rube Goldberg Machines
Transfers energy from the beginning to the end. Types of energies generally include gravitational, elastic, and kinetic.

4. Rube Goldberg Machine
The energy is often transferred using simple machines. The six simple machines are:
Lever
Pulley
Wheel and Axle
Inclined Plane
Wedge
Screw

5. Rube Goldberg Machine
Lever – a ridge bar that rest on a fulcrum, used to help lift an object.

6. Rude Goldberg Machine Lever Examples
Crowbar, scissors, pliers, nut cracker, wheel barrow, hammer, shovel

7. Rube Goldberg Machine Pulley
A pulley consists of a grooved wheel that turns freely in a frame called a block.

8. Rube Goldberg Machine Wheel and Axle
The wheel and axle is a simple machine consisting of a large wheel rigidly secured to a smaller wheel or shaft, called an axle.

9. Rube Goldberg Machine Incline Plane
An inclined plane is an even sloping surface.

10. Rube Goldberg Machine Wedge
The wedge is a modification of the inclined plane. Wedges are used as either separating or holding devices.

11. Rube Goldberg Machine Screw
A screw is an inclined plane that is wrapped helically around an axis
