Inventions

1400's My first invention is the Anemometer. It was created in 1450 by Leon Battista Alberti. This invention was helpful because it helped us measure wind speed and velocity. This may have helped us by helping us know whether or not we can do certain things on certain days because of the wind speed and velocity. Before we had no way to know what the wind speed or velocity was.

1600's The second invention is matches. It was created in 1680 by Robert Boyle. They helped by enabling us to put out fires but be able to quickly light them again. Matches were light weight and they were very useful to start fire and do other thingsd that you would not be able to do with bigger fires.

1700's My third invention is the cotton gin. It was created April 1793. It was created by Eli Whitney. It was extremely helpful because it sped up the harvesting of process of cotton making. It also made cotton more profitable for the southern states. It made cotton production require less hours for workers. It removes the seeds from the cotton.

1800's My fourth invention is air brakes. It was created April 1869 by George Westinghouse. It helped society because it enabled locomotives to stop using fail safe accuracy by the engineer for the first time. Before accidents were often because each car had individual brake men following a signal from the engineer.

1900's My last invention is disposable diapers. It was created in 1949 by Stanley Mason. They made it safer because they did not have pins so the baby could not injure themselves in anyway. Also it did not have any leaks unlike the cloth diaper early invented.

Technology is things that are created and used by people it effects us by making our life easier and help us do jobs faster. It has gooton faster and smaller and better over time. Inventions have impacted society by making things faster and easier than before. When ever a job is really hard and slow that drives us to make new inventions to make it easier and faster. My document shows you how things have helped make life easier and faster for us.
