Technology and Change

 In Social Studies, we have been working on technology advancements through time. We got into groups and chose a time of period to research about(Stone age, 20th century, etc). My group and I chose the 20th Century. After this task, we made an essay about it.  

Technology and Change Essay 

Paragraph 1: Introduction.

Re-state what the question is in a paragraph

During the 20th Century period, there were many significant technological advancements. Some of the

important inventions during this time were television, Motorola DynaTC 8000x, and vacuum cleaner.

These inventions are still widely seen and used today.

Paragraph 2: Invention 1 explained

State what the invention is, what it does and how far it has come up until today

A significant invention during the 20th Century is television. This technology was invented in 1927 by the

inventor named Philo Taylor Farnsworth. Television is an electronic device that displays sound and

image which creates programs for information, entertainment and education. With this device, we are

able to learn what’s going on around the world with the help of news. Interestingly, televisions before the

1950s were displayed in black and white. In today’s time, televisions are displayed in colour. They are also

lighter and bigger than before. The most common television used right now is a flat panel and a LED TV.

A flat-panel TV is a television displayed in a flat, thin format. A LED TV is the same as the flat-panel TV

but it has a LED light behind it. TV nowadays allows you to access many things which makes this

invention important during this time era and today.

Paragraph 3: Invention 2 explained

State what the invention is, what it does and how far it has come up until today

Another significant invention during the 20th Century is the handheld cellular phone which is called

‘Motorola DynaTC 8000x’. It was invented on April 3, 1973, by an American engineer named Martin

Cooper. He was also the first person to make a phone call. This device was first launched in 1983 and

cost $4,000. Its battery life can last between 30-35 minutes and takes 10 hours to re-charge. It weighs

1.1 kg and is about the size of a brick. Despite its heavyweight, poor battery life, and its other flaws, it

was widely known for its significant used during 20th Century period. It was the first device that allows

people to call someone without it attached to a wire. The Motorola DynaTC 8000x is still used today but

it’s reconstructed differently. Today, this device is called ‘cell phone’. A cell phone doesn’t only allow you to

call but you can take pictures, play games and text messages with it. Currently, there are 3.5 billion

cellphones sold around the world which makes it popular and significant to human beings. 

Paragraph 4: Invention 3 explained

State what the invention is, what it does and how far it has come up until today

A different significant invention during the 20th Century is a vacuum cleaner. A vacuum cleaner is a

technology that sucks up dirt and dust. It cleans floors as well as other surfaces. This was invented in

1901 by Hubert Cecil Booth. Before he made his invention, he placed a handkerchief on a chair and put

his mouth on it. He then sucked the air in and realized how much dust he gathered using a handkerchief.

This idea inspired him to make the vacuum cleaner. Unfortunately, the invention he made was so large

that it had to be carried by a horse. Today, there are many types of vacuum cleaners and it can come in

different sizes and models. Some can move by themselves and some can even collect liquid. Vacuum

cleaners are now one of the most popular technologies which are very helpful and important to people. 

Paragraph 5: Conclusion

Go over the points you have just made above

In conclusion, there were many significant inventions seen during the 20th Century time period. Some of

these inventions were television, Motorola DynaTAC 8000x and vacuum cleaner. These are all

commonly seen today all around the world and are still important.
