Key Words Simple machines, complex machines, work, wheel, axle, inclined plane, wedge, screw, lever, pulley Summary The students will be introduced to the seven types of simple machines and their functions. The students will be challenged to identify simple machines they come in contact with everyday.
Machines are tools that help people do work more easily. In physics, you do work anytime you use force to move an object. Skateboards, cars, bikes, shovels, boats, doors, light switches, and stairs are all machines. Simple machines are the most simple tools. There are six of them: LEVER WHEEL & AXLE PULLEY INCLINED PLANE SCREW WEDGE
Lesson Synopsis. Students learn the basic principles of simple machines and explore everyday uses. Simple machines are "simple" because most have only one moving part. "Work" is only done when something is moved (displaced) by a force (push or pull). Machines do not reduce the amount of work for us, but they can make it easier. Year Levels.
Define a problem that can be solved with the use of simple machines. Collaborate to sketch a solution to the problem Compare solutions to predict which will work better.
Machines are devices by means of which a primary force (called the effort) exerted over some displacement at one location gives rise to a secondary force (called the load) and displacement at a different location.
Simple Machines 1 introduces students to the six types of machines that make work easier to do. These are the inclined plane, wedge, screw, lever, wheel and axle, and pulley. Students will learn to name and describe these machines and will be able to invent something that uses at least two of them.
A machine is, in a very general sense, a combination of parts we use to over-come a resistance (which is also a force, like a large rock that needs to be removed) by transferring or transforming energy, usually that exerted by a human being. There are fundamentally three basic machines — the lever, the inclined plane and the wheel and axle.
