• create a time line that includes at least 10 machines in total
• you must start in the year 1300 or earlier and end within the last 10 years
• all six types of simple machines must be present
• each time line entry must include the name of the machine, an explanation, an illustration of the machine and information regarding who invented the machine
• your time line should include how the machine works and what problem the machine solved in that time of history
1. Year: 300 BC
Machine: Lever
Explanation: A lever is a simple machine that consists of a rigid beam or rod pivoted at a fixed point called a fulcrum. It helps to lift or move heavy objects with less effort.

2. Year: 200 BC
Machine: Wheel and axle
Explanation: The wheel and axle is a simple machine that consists of a circular object (the wheel) attached to a rod (the axle). It allows for the efficient movement of objects by reducing friction.

3. Year: 100 AD
Machine: Pulley
Explanation: A pulley is a simple machine that consists of a wheel with a groove and a rope or cable that wraps around it. It allows for the lifting of heavy objects by distributing the weight across multiple ropes.

4. Year: 400 AD
Machine: Inclined plane
Explanation: An inclined plane is a simple machine that is a flat surface that is tilted at an angle. It allows for the easier movement of objects up or down a slope, reducing the amount of force needed.

5. Year: 600 AD
Machine: Screw
Explanation: A screw is a simple machine that consists of a long inclined plane wrapped around a cylindrical post. It is used to fasten objects together or to lift heavy loads by rotating the screw.

6. Year: 800 AD
Machine: Wedge
Explanation: A wedge is a simple machine that is a triangular-shaped object used to split or lift objects apart. It helps to apply force in a concentrated area to accomplish a task more efficiently.

7. Year: 1000 AD
Machine: Waterwheel
Explanation: The waterwheel is a machine that uses flowing water to generate power for grinding grains or other tasks. It harnesses the energy of moving water to perform mechanical work.
Illustration:
8. Year: 1200 AD
Machine: Windmill
Explanation: A windmill is a machine that uses the power of wind to generate electricity or pump water. It consists of rotating blades that are turned by the wind to produce energy.

9. Year: 1600 AD
Machine: Steam engine
Explanation: The steam engine is a machine that uses the power of steam to generate mechanical work. It played a key role in the Industrial Revolution by powering factories, transportation, and more.

10. Year: 2000 AD
Machine: Computer
Explanation: A computer is a machine that processes information and performs tasks based on programmed instructions. It revolutionized the way we work, communicate, and access information in the modern world.
