  Marconi was born in Italy in 1874.

He was a great scientists and famous inventor.

He had a lab in which he did a lot of experiments with radio waves.

LABORATORY

laboratory – lab

Marconi wanted to invent a telegraph machine without wires.

wires

His machine used radio waves instead of wires in order to send messages through the air.

At first it could not send signals for more than a kilometer.

That is why Marconi kept working hard. He wanted to build a better machine to send messages across the ocean.

In 1901 he went to Newfoundland and installed a lot of antennas.

He tried out his machine and it worked. Marconi sent a radio signal to a nearby ship and the ship sent a message back.

That ship was about 3500 kilometers across the Atlantic Ocean.

In 1909 Marconi won a Nobel Prize.

 Marconi invented the radio too!

It could send voices over the air. He set up his own radio station.

When he died in 1937 all radio stations fell silent for two minutes to honour him.

Useful tips!

  • Talk about scientists and inventions.

  • Try to explain the difference between a telegraph machine and a telephone.

  • Try to explain the difference between an invention and a discovery.

THE INDUSTRIAL REVOLUTION

      The Industrial Revolution is the period between 1760 and 1840 in Great Britain. It is the time when a lot of important things were invented. For example,  the steam power, the telegraph and the factories! Most of the industries produced textile and clothing. During this historical period cities became bigger and bigger and plenty of people left the land they worked in the countryside to move in the cities. They all worked in factories where the conditions were horrible. The newcomers lived in small rooms, worked for long hours and had very poor hygiene. They were not paid very well and were often separated from their children. The children had to work too!!! One of the work they had to do was to clean the chimneys of the factories and the houses!!! This was a typical job for them because, being small, they could get into the chimneys and clean them well. These children were called chimney sweepers.

      During the Industrial Revolution a lot of kids were orphans and had to live with other children without parents or relatives. It is true that the times were difficult but it is also true that they were exciting. The train could transport heavy goods  and people could travel long distances for shorter time. The telegraph helped them receive news faster. These were all signs of progress! We can say that the Industrial Revolution is a very particular type of revolution because it was based mostly on economic and social changes. Soon after the Industrial Revolution began in England, it crossed the ocean and reached America too.
