Simple Machine Lesson Plans | ApplianceHelp A simple machine is a device used to assist people in getting work done faster and easier. Scientifically, work is known as using force upon an object in order to transport it to a new location. Pushing, pulling, and lifting are all common forms of work. Simple machines can used to simplify these actions, making it easier for the laborer to complete the task. Pulleys, levers, wedges, screws, wheels and axles, and inclined planes are all examples of simple machines. They can all help people do work in some form. Here is a list of links to lesson plans and resources for teaching students about simple machines. Simple Machine Terms – An article containing the definitions of of the six simple machines.

Kids Do Ecology Victorian Flea Circuses: A Lost Art Form "QUANTUM SHOT" #549Link - by A. Abrams If you can make a flea cooperate with you, you're probably good at politics I have to say, this is probably the strangest subject we ever talked about on Dark Roasted Blend. However, it is such a rich showcase of miniature art and craftmanship, and the "wow" factor is there as well: A flea, with legs finer than a human hair, can pull up to 700 times its own weight! (art credit: Leah Palmer Preiss) "Big fleas have little fleas... Andy Clark sends us his latest project - he's been researching this topic for about four years now and regularly publishes new discoveries along with other flea news on the Flea Circus Research Library blog. "The idea to make a Victorian Flea Chariot came to me when I wondered if it's possible to use simple techniques available in the 1800s to make one today. The chariot is approx 10mm long by 7mm wide and made from brass; the wheels are 5mm in diameter. Making the chariot can be seen here, with video of a final product. ...

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 HOMEMADE SCIENCE TOYS AND PROJECTS Magnet Man - Cool Experiments with Magnets Cool Experiments with Magnets This web site is devoted to magnetism and the cool experiments you can do with permanent magnets and electro-magnets. Some of the experiments are very basic - things you've done since third grade. Others are unique - perhaps you hadn't thought of doing some of these before, or had difficulty in trying to set them up. Lists of the materials needed for the demonstrations, directions on how to assemble them, instructions on how to show them, and notes on how they work are all here for you. Also shown are several cool magnetic toys you can buy. Have fun with hands-on experiments! Rick Hoadley(For other cool toys and puzzles, check this out!) Last updated: 26 Feb 2017. , that means that at the underlined link there is some kind of experiment you can buy or build which will help you learn about the world of magnetism.
