Secret Worlds: The Universe Within - Interactive Java Tutorial Secret Worlds: The Universe Within View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. InventorsToolbox: The Elements of Machines Simple Machines: These devices were all in common use for centuries before Leonardo's time. Each one makes work easier to do by providing some trade-off between the force applied and the distance over which the force is applied. Wheel and Axle In this machine a wheel or spoke is locked to a central axle so that when one is turned the other must turn. A longer motion at the edge of the wheel is converted to a shorter more powerful motion at the axle. In reverse, a short powerful force at the axle will move the wheel's edge a greater distance. Pulley System A single pulley simply reverses the direction of a force.

All About Simple Machines: Types and Functions - Easy Science For KidsEasy Science For Kids Every day you use machines without even thinking about it. A machine is anything that helps make work easier. Basic tools like staplers, screwdrivers and scissors are simple machines. These machines are all based on simple inventions like levers, planes, pulleys or wheels. All About Simple Machines: These are samples of simple machines. A lever is a stiff board or bar that rests on a base called a fulcrum.

Science Matters Yah, I know some of us are winding down from schooling for the summer months, but I can’t help but stay on the lookout for resources I know I’m going to be needing again all too soon. I’ve come across some interesting science things of late that I want to check out – perhaps you, too, can find something useful. For your perusal: Free Online Textbooks and Curriculum Simple Machines: Facts (Science Trek: Idaho Public Television) Once upon a time a person needed to move something heavy. He or she picked up a long stick and stuck it under the edge of the heavy object and then pushed down on the other end of the stick. And the first simple machine was invented. Simple machines are just that. The simplest form of using one thing to accomplish something faster or better.

Rube Goldberg : Home of the Official Rube Goldberg Machine Contests The Rube Goldberg Machine Contest (RGMC) is an annual international competition that challenges teams of students from middle school to college age to compete in building the most elaborate and hilarious Rube Goldberg Machine. A Rube Goldberg Machine is an overly complex contraption, designed with humor and a narrative, to accomplish a simple task. The 2015 Task is: ERASE A CHALKBOARD. Team Registration is open now! The RGMC is STEM and STEAM friendly, and Teams and their machines are judged on a range of criteria from absurd complexity, reliability, team chemistry, creativity, humor and story-telling -- along with the successful achievement of the task at hand.

ASPIRE Simple & Comples Machines In an unknown time and an uncharted place, the ASPIRE crew has accepted the challenge to assist in the completion of a city being constructed of massive stones. They must work without the advantage of modern technology. They have agreed to rely primarily on the use of the six simple machines to accomplish their mission. Before getting to work, two crew members, Harry and Pic, have used available materials to fashion themselves a tetter-totter just to give them something to do for fun. This never seems fair.

Dirtmeister: Simple Machines Dirtmeister's Home The Inclined Plane The inclined plane is the simplest of simple machines because to make it work, nothing moves. You move! Another name for an inclined plane is a ramp. It can be as simple as the driveway leading to your school or as sophisticated as the staircase in the Empire State Building. A ramp works by helping you lift things more easily up to a higher level.
