Dirtmeister: Simple Machines -- Inclined Plane Dirtmeister's Home The Inclined Plane The inclined plane is the simplest of simple machines because to make it work, nothing moves. You move! Remember, there's always a trade-off. Dirtmeister's Home | Simple Machines | Teacher's Guide | Science Observer Astronomy Picture of the Day Discover the cosmos!

Science for Kids: Balancing Robot (FREE Printable) Here’s a super fun science activity that really gets kids thinking! Children will explore balance and center of gravity by creating a balancing robot! Follow our Science for Kids Pinterest board! *This activity was originally published on June 1, 2014 and has since been updated. This balancing robot science exploration has always been a huge favorite among my students! In this science activity kids will place two pennies in various locations on a paper robot until they’ve discovered how to make the robot balance. Materials for Balancing Robot Science Activity How to Make the Balancing Robot Print out the free printable on a sheet of white card stock, and color the robots if you’d like. To make the robot balance you’ll want to stick two pennies onto the hands of the robot. Here’s how we did it: Flip your robot over to the back. Press a penny onto each hand. Stick some more poster putty on the pennies. Press the second robot onto the back. Now you’ve got your balancing robot!

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. Pulley System A single pulley simply reverses the direction of a force. Wedge A wedge converts motion in one direction into a splitting motion that acts at right angles to the blade. Screw A screw is a central core with a thread or groove wrapped around it to form a helix. Lever A lever is a stiff rod that rotates around a pivot point. Other Elements of Machines: Though these devices were also used in machines in Leonardo's time, he experimented with them and made changes to improve how they worked. Gears Gears are toothed or pegged wheels meshed together to transmit motion and force. Cam A cam is a wheel with shaped bumps on it.

Make a Cloud Mobile Make a Cloud Mobile This mobile of beautiful, feather-weight clouds is balanced so that any gentle breeze sends them turning and twisting. Some are rain clouds, dropping sparkling showers below. But it's not just a pretty work of art. You can make this cool Cloud Mobile with common materials and supplies—and a little patience to get it balanced just right. Here's how to make your mobile. Seeing through the clouds CloudSat is an Earth satellite that studies the clouds in ways never before possible. Knowing how clouds affect Earth's climate is very important. Here is a CloudSat poster showing all the cloud types and comparing their altitudes in the sky. I hung my Cloud Mobile over my bed.

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. A tool. There are 6 basic simple machines; the lever, the wheel and axle, the inclined plane, the wedge, the pulley, and the screw. But what is work? The Lever The lever is a long tool such as a pole or a rod put under an object to lift it. Levers are all around us. The Wheel & Axle The wheel has always been considered a major invention in the history of mankind. Wheels are found where things turn in a circle such as an electric fan, a motor, a revolving door, a merry go round, and any wheel — on the car, on your skateboard, or on a bicycle. The Inclined Plane The inclined plane is simply a ramp. The Wedge The Pulley The Screw Measuring Work

Loco Beans 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. Drag the slider bars to move Harry and Pic until they have becomed balanced. Simple machines give us an advantage by changing the amount, speed, or direction of forces. Would you have a problem if the door knob came off in your hand before you unlatched the door? From day to day do you find yourself using any of the six simple machines: Wedge Lever Incline Plane Pulley Wheel Screw
