Simple Machine
This document introduces the six types of simple machines: wedge, wheel and axle, lever, inclined plane, screw, and pulley. It describes how each machine works and provides everyday examples. Simple machines make work easier by reducing the amount of force needed to move or lift an object. Complex machines combine two or more simple machines to further increase mechanical advantage.
Inclined Planes Screws Wedges
An inclined plane is a slanted surface that makes it easier to move an object upward than lifting straight up. It is easier to move an object up a more gradual, longer inclined plane than a steeper, shorter one. Inclined planes reduce the effort needed to move something over a long distance or raise it higher. A screw is an inclined plane wrapped around a pole or rod, and is used for holding things together, drilling, and lifting. A wedge is two inclined planes back to back, used for cutting, chopping, splitting things apart, and holding things in place. Common examples of each include ramps, stairs, drills, wood screws, axes, and knives.

Simple machine Year 6.pdf
Machines make our lives easier by allowing us to do more work with less force. There are two types of machines: simple and complex. Simple machines have few or no moving parts and include the wheel and axle, lever, inclined plane, screw, gear, pulley, and wedge. Each simple machine works by applying the mechanical advantage principle to multiply force or change its direction.
Type of simples machine
The document defines and describes the six classical simple machines: the lever, pulley, inclined plane, screw, wedge, and wheel and axle. Each machine is described in one to three sentences explaining its basic function and components. The lever has a fulcrum and uses resistance and effort forces. A pulley changes the direction of force applied and may be fixed, movable, or compound. An inclined plane provides mechanical advantage through distance rather than effort. A screw uses inclined threads to convert rotational to linear motion. A wedge uses an inclined plane to split or hold materials. A wheel and axle functions as a rotating lever with the axle as the fulcrum.
Simple machines
This document discusses simple machines and their uses. It describes six simple machines: levers, wheels and axles, inclined planes, wedges, screws, and pulleys. For each machine it explains how they work by magnifying an input force or reducing the amount of force needed. Simple machines have been used for thousands of years and were studied by Archimedes. They can be combined to create mechanical advantages in devices like bicycles.
Leo presentation
Pulleys are simple machines that help change the direction and point of application of a pulling force. Pulleys reduce the amount of force needed to lift a load by using wheels with grooves to direct ropes or cables. While the force required is reduced, the same amount of work is needed to lift the load to a particular height. Pulleys have many applications and can be found in cranes, automobiles, airplanes, and most machines.
Leo presentation
A pulley is a wheel with a groove that holds a rope or cable and changes the direction of a pulling force. Pulleys are often used in sets to reduce the amount of force needed to lift a load, though the total work required remains the same. Pulleys have many applications, including lifting objects with cranes and in automobiles and airplanes. A wedge is a piece of material thick at one edge and tapered to a thin edge, used for splitting, tightening, or levering. Examples include knife blades and scissors. An inclined plane is a surface set at an angle to the horizontal that raises or lowers loads by rolling or sliding, such as a ramp.
Lathe machine
The document provides information on the history and evolution of lathe machines. It describes early lathe models that were powered manually like the strap lathe, bow lathe, and pole lathe. It then discusses more advanced lathes that used mechanical power sources like the treadle lathe and lathes powered by a great wheel. The document also outlines the main components of a lathe like the headstock, spindle, tailstock, carriage, and tooling. It provides details on workholding devices, lathe operations, and different types of lathes used for various applications.
Notes simple machines
There are 6 simple machines: the lever, inclined plane, wheel and axle, screw, wedge, and pulley. They were first defined by Renaissance scientists and make work easier by changing the direction or magnitude of forces. Simple machines allow an applied force to work against a load through mechanical advantage. They transform energy rather than create it, as discovered by Galileo. Each machine functions differently based on its design and placement of fulcrums.

Respiratory system
The respiratory system allows us to breathe by moving air into our nose and down into our lungs. The nose filters air as it enters, while the trachea is a tube that carries air to the lungs. In the lungs, oxygen passes into the bloodstream and carbon dioxide is released, with the diaphragm and rib cage working together to expand the lungs and draw in air.
circulatory system by tenerias
The document summarizes circulation and the circulatory system. It explains that the heart pumps blood through arteries, veins, and capillaries to distribute oxygen and nutrients to the entire body in systemic circulation. The document also describes pulmonary circulation, where blood picks up oxygen in the lungs and returns to the heart via pulmonary veins. It defines the functions of key blood vessels like the aorta, which carries oxygenated blood from the heart to the body, and the superior vena cava and capillaries.
Digestive system
The document summarizes the stages of digestion, including chewing food in the mouth, food moving through the esophagus into the stomach where it mixes with gastric juices to form chyme, and finally the chyme leaving the stomach and entering the small intestine where it mixes with juices from the intestine, pancreas, and liver to separate out all the substances needed. The liver is noted as the only organ able to regenerate itself, allowing part of one person's liver to be donated to another.
