Pulitzer Prize winning cartoonist, sculptor, and author Went to college to become an engineer moved from San Francisco to New York drawing daily cartoons for the Evening Mail believed that there were two ways to do things: the simple way and the hard way Through his cartoon inventions, Goldberg discovered difficult ways to achieve easy results Rube Goldberg, 1923, Popular Science Magazine
To see some of Rube Goldbergs original cartoon inventions, visit this webpage: Rube Goldberg Cartoon Gallery Rube Goldberg Cartoon Gallery Videos of students Rube Goldberg machines can be found at 8th grade Rube project or Katie's 6th grade project8th grade Rube projectKatie's 6th grade project Or here amazing Rube machineamazing Rube machine
1. Turn the handle on a toy cash register to open the drawer.2. The drawer pushes a golf ball off a platform, into a small blue funnel, and down a ramp.3. The falling golf ball pulls a string that releases the magic school bus (carrying a picture of Rube Goldberg) down a large blue ramp.4. Rube's bus hits a rubber ball on a platform, dropping the ball into a large red funnel.5. The ball lands on a mousetrap (on the orange box) and sets it off.6. The mousetrap pulls a nail from the yellow stick.7. The nail allows a weight to drop.8. The weight pulls a cardboard "cork" from an orange tube.9. This drops a ball into a cup. 10. The cup tilts a metal scale and raises a wire.11. The wire releases a ball down a red ramp.12. The ball falls into a pink paper basket.13. The basket pulls a string to turn the page of the book!
The Lever A lever is a board or bar that rests on a turning point called the fulcrum. An object that a lever moves is called the load. The closer the load is to the fulcrum, the easier it is to move. The claw end of a hammer that you use to pry nails loose is an example of a lever.
Inclined Plane It is a flat surface that is raised on one end. A common inclined plane is a ramp. Inclined planes make it easier work to move objects either higher or lower.
Wheel and Axle The axle is a rod that goes through the wheel. The wheel, the round part, spins and turns the axle and allows both to move It is much easier to move things with wheels and axles.
Screw An inclined plane wrapped around a cylinder becomes a screw. A screw has sharp ridges and is not smooth like a nail. Screws can be used to lower and raise things. Screws can be used to hold objects together, like the screw on lid of a jar of peanut butter!
Wedge A wedge is made up of two inclined planes. These two flat planes meet and form a sharp edge that can be used to push things apart. A fork or the blade of an axe are both wedges. The edges of the blades are smooth slanted surfaces.
Pulley Instead of an axle, a wheel can rotate a rope or cord. In a pulley, a cord wraps around a wheel When you pull on one side of the cord, the wheel turns and the load will move. Pulleys are good for making moving heavy loads a lot easier.

Your goal is to work in groups to create a complex machine that uses at least 4 separate steps to complete the task: pop a balloon. Today, you are to draw your ideas for your machine. In the next lab, we will begin construction and testing of your complex machines.
