Please HELP!!! I need a unique Innovation that changed history!?

Assembly lines! You could talk about how machinery in the early 1900s totally changed the labor force, which led to all kinds of things like child labor and Taylorism (look it up) and dangerous working conditions and such. That, in turn, caused the labor movement, which was huge and still affects us today.

Three aspects of American culture are but are not limited to the American flag as a symbol, language, and the internet. These three aspects are all innovations unique to this society.

The American flag to Americans isn't just a flag; it symbolizes many aspects that make up this country. The American flag is comprised of red and white stripes and white stars on a blue background. The colors that make up the American flag according to the House of Representatives in a book that was published in 1977 explains that the white symbolizes purity and innocence, red stands for hardiness and bravery, and the blue is the color of the Chief. The broad band above the stripes signifies attention, firmness and justice. The star symbolizes the heavens and the celestial purpose to which man has desired from the beginning of time. The stars collectively represent each state within America that make up the United States. The stripes are the rays of light stemming from the sum. In simple terms when many Americans see the flag to them it means honor, freedom, loyalty, strength, and bravery to name a few (Streufert, 1994). To deface an American flag shows to utmost disrespect to all Americans and out country. This is why many rival countries play upon this act to show they do not like Americans.

Language is very unique to this society simply because there are many different cultures living within this country that have adopted the English language as their second language as a means to further themselves while living in America. I think it shows a lot to have had immigrants of yesterday and today enter this country with their native language and their families and out of eagerness learn the American way start by learning the common language. Although languages of these immigrants are still spoken in America within their own cultural groups English is still spoken. Today America is a bilingual country because of the many immigrants who now call America their home. As a result of this many American citizens have chosen to learn other languages as well.

The World Wide Web is certainly an innovation unique to American society. The WWW also known as the internet has changed the way we communicate in and outside of the United States. Born in 1992, since then us as Americans have learned how to live in a society where we can send emails all over the world as well as shop online. Because of this unique innovation many American can save money and time by using the internet instead of the post office.

I hope this helps.... :")

Eli Whitney's Cotton Gin

Eli Whitney was known as the King of Cotton, as he invented the cotton gin and greatly increased cotton production. The cotton gin allowed the cotton part (we use for clothing) to be stripped from the seeds by machine, as opposed to by hand. This obviously increased the speed of stripping the seeds off. Whitney's original intention for this machine was to help decrease the amount of slaves needed in the Southern US, as on cotton plantations, stripping seeds was one of their many jobs. However, the machine unfortunately had a reverse affect. Farmers saw the cotton gin as an opportunity for faster production, but now that they could strip seeds faster, they needed to pick cotton faster. Therefore, more slaves were purchased to pick the cotton, and the cotton economy (and the economy of the South as a whole) was sped up.
