We are learning a lot of interesting facts about inventions and discoveries.
Let’s continue the adventure!
_ An invention is a new thing that someone has made. The computer was an invention when it was first made. We say when it was “invented”. New things that are made or created are called inventions. Cars and plastics are inventions that everyone knows. Inventions are made by inventors.
_ Many historians consider the wheel, the spear, the knife, and the arrow as the earliest inventions. They were created because of the need to hunt , provide protection and transportation.
_ Some of the most famous inventors are: Archimedes, Albert Einstein, Leonardo Da Vinci, Benjamin Franklin, Thomas Edison, Johannes Gutenberg, Alexander Graham Bell, George Washington Carver, Eli Whitney, the Wright Brothers, John Baird, Henry Ford, George Eastman, and Heinrich Hertz.
_ Probably one of the most famous inventor we all take for granted is Levi Strauss. Mr. Strauss invented blue jeans.
_ There are also many women inventors, however they are not as famous as their male counterparts. Where would the world be if Mary Anderson had not invented the windshield wiper for the automobile?
You have to inquire about one of the most important inventors, Thomas A. Edison, who invented the first commercially practical incandescent light bulb. In 1878, Edison formed the Edison Electric Light Company in New York City, on that occasion he said: “We will make electricity so cheap that only the rich will burn candles.
After this invention, daily life was much easier than before.

Who invented the telephone?
Most people will say that the telephone was invented by Alexander Graham Bell but this isn’t completely true.
Antonio Meucci had already invented a voice-communication apparatus which can be considered as the first telephone when Alexander Graham Bell was only 2 years old!
Watch this video but keep in mind that the first telephone was invented by Antonio Meucci and Graham Bell made a more modern telephone many years later.
Books, books and more books! Libraries are full of them. Bookshops sell hundreds of books every year.
Can you imagine your life without books?
Well, books are eveywhere, but before the invention of the printing press by Gutenberg things were much more difficult. Books had to be produced by hand and it was hard work, and expensive!
The invention of the printing press revolutionized the accessibility of knowledge in the Western World.
Watch this video and take some notes for your school project!
¡Hola a todos!
Comenzamos una nueva Unidad de Indagación : “Cuéntame un invento”.
Idea central: Los inventos y decubrimientos del hombre han surgido como resultado de ciertas necesidades a través del tiempo.
Perfil: Informados e instruidos, audaces y solidarios.
A lo largo de esta unidad conoceremos cómo han ido evolucionando los inventos, entenderemos por qué el ser humano inventa y reflexionaremos sobre la importancia de los inventos para la mejora de la calidad de vida.
Podemos aprender mucho sobre los inventos mientras jugamos…
Marie Curie was the author of a theory of radioactivity and the discovery of two elements, polonium and radium. She was the first woman to win a Nobel Prize and she was also the first woman to become a professor at the University of Paris.
Marie Curie’s discoveries would make radiotherapy treatments possible. So Marie Curie is well known for her contributions to the field of medicine.
You can learn more about her if you watch the video.

Let’s talk about Wood!
Wood comes from trees.
It is strong, flexible, long lasting and opaque.
Wood is used to make things such as furniture that need to be strong and last a long time.
Wood is an insulator of heat and electricity.
Let’s talk about fabrics!
Fabrics are made from thin fibres woven together.
- Some fabrics, such as wool, cotton and silk, are natural (the fibres come from living things).
- Some fabrics, such as polyester and nylons are made from synthetic fibres, which are made in factories, from chemicals.
Different fabrics have different properties. Fabrics can be stretchy (a pair of tights), insulating (keep you warm, like a woollen coat) or absorbent (a towel).
Fabrics are used to make clothes as they are flexible and comfortable, can be warm and do not wear out easily.
Let’s talk about glass!
Glass is made by melting sand and other minerals together at very high temperatures.
Glass is normally transparent, waterproof and can be made into many different shapes. Thick glass can be strong, but thin glass will break very easily.
Glass is used for objects that need to be transparent such as windows and glasses.
Let’s talk about plastic and its properties!
Plastics are materials made from chemicals and are not found in nature. They are strong and waterproof, and can be made into any shape by applying heat. Plastics can also be dyed different colours or made to be transparent.
Plastic is not magnetic. It is a good electrical insulator as it does not conduct heat or electricity.
Plastics are used to make all sorts of things, such as bags, bottles and toys.
