1. Wheel and Axle
Year Invented: ~3500 BC
Explanation: The wheel and axle is a simple machine that consists of a wheel attached to a rod, known as an axle. This invention revolutionized transportation by allowing heavy loads to be moved with ease by rolling them along the ground.
Inventor: Unknown
2. Lever
Year Invented: 260 BC
Explanation: The lever is a simple machine that consists of a rigid bar that pivots on a fulcrum. By applying a force on one end of the lever, a larger force is generated on the other end. This allowed for the lifting of heavy objects with less effort.
Inventor: Archimedes
3. Pulley
Year Invented: 1500 BC
Explanation: The pulley is a simple machine consisting of a wheel with a groove along its edge and a rope or cable that runs through the groove. By using multiple pulleys, the direction of the force needed to lift an object can be changed.
Inventor: Unknown
4. Inclined Plane
Year Invented: 450 BC
Explanation: The inclined plane is a simple machine that is a flat surface that is angled. This allows for objects to be moved up or down with less effort compared to lifting them vertically.
Inventor: Archytas
5. Screw
Year Invented: ~200 BC
Explanation: The screw is a simple machine that is a spiral inclined plane wrapped around a rod. This design allows for the turning of the screw to create motion. Screws are commonly used in fastening objects together.
Inventor: Archimedes
6. Wedge
Year Invented: 3500 BC
Explanation: The wedge is a simple machine that is a triangular-shaped tool that is used to split, lift, or separate objects. It works by applying force to the thick end of the wedge, which then forces the two objects apart.
Inventor: Unknown
7. Water Wheel
Year Invented: 1st century BC
Explanation: The water wheel is a simple machine that uses flowing or falling water to generate power. It was used to grind grain, power sawmills, and even generate electricity in modern times.
Inventor: Greek Engineer Philo of Byzantium
8. Gear
Year Invented: c. 50 BC
Explanation: Gears are toothed wheels that mesh together to transmit motion or torque. They are used in machines to change the speed or direction of motion and are crucial in the functioning of many devices, from clocks to cars.
Inventor: Heron of Alexandria
9. Steam Engine
Year Invented: 1712
Explanation: The steam engine is a machine that converts heat energy into mechanical work by using steam as the working fluid. It played a crucial role in the Industrial Revolution by powering trains, ships, and factories.
Inventor: Thomas Newcomen
10. Computer
Year Invented: 1943
Explanation: Computers are complex machines that can store, retrieve, and process data. They have revolutionized information technology and communication, making tasks faster and more efficient.
Inventor: Howard Aiken, Grace Hopper
Create a timeline that includes at least 10 machines in total.
You must start in the year 1300 or earlier (think invention of the wheel BC) and end within the last 10 years (2012 to present).
All six types of simple machines must be present.
Each timeline entry must include the name of the machine, an explanation, an illustration/picture/blueprint of the machine and information regarding who invented the machine.
Your explanation should include how the machine works and what problem the machine solved in that time of history.
Your timeline should be created in a way that allows you to make it visually interesting and appealing but you are not limited to any one format.
