History of Computers

This would be biger than your room

Today we all have a computers for most things! Its amazing really, but the computer has been around for longer than you think.

The first computer ever made was bigger than your room. It had over one million wire’s inside! So do you think your computer’s old?

It was 1939, John V. Atanasoff and Clifford Berry developed the Atanasoff-Berry Computer (ABC) at Iowa State University, which was regarded as the first electronic digital computer. The ABC was built by hand and the design used over 300 Vacuum Tubes and had capacitors fixed in a mechanically rotating drum for memory.

The ENIAC (Electronic Numerical Integrator and Computer), was constructed in the US in 1943. It was the first really useful general-purpose computer. It was a turning point in the history of computing and was used to perform calculations and used 160 kW of power.

World War II is known to be the driving force of computing hardware development and one of such use of computers was in communications encryption and decryption. The most famous of these was the Enigma machine which broke German codes.

And in 1962 the first computer game was made, (YAY!).

The microprocessor eventually led to the development of the microcomputer during the 70′s and 80′s.

These were small, low-cost computers that individuals and small businesses could afford.

In 1985 Microsoft and Apple started a long battle over who made the best computers and software.

By the 1990s, the microcomputer or Personal Computer (PC) became a common household appliance, and became even more widespread with the advent of the Internet. Did you know that the mouse is called the mouse because of the wire coming out ofthe back.

Sir Timothy John “Tim” Berners-Lee is an English computer scientist known as the inventor of the World Wide Web as we know it today. He made a proposal for an information management system in 1989, and on 25 December 1990, with the help of Robert Cailliau and another young student, he carried out the first successful communication between a Hypertext Transfer Protocol (HTTP) client and server via the Internet.

If the Internet was not here what would we be talking on? We use the internet for lots of things today.

Now you know all about computers and now you are ready for the internet.

Gary The Clown

Today Gary the Science clown came in to talk to us. He spent the morning with several classes and then had an hour with the whole school.

He taught us lots of things about science and half the time we didn’t even realise we were learning because it was so much fun!

Some of us went up on stage and he showed us lots of tricks on gravity and how it works. Not only did we learn we had lots of fun.

Here is a photo of his presentation:

Its not rocket science… Or is it.

On Tuesday 22nd of May year 6 and Reception did a science experiment on rockets. They all loved it and wouldn’t stop talking about it all  week 

On the floor was a purple pump that you jumped on to make a rocket shoot up into the air.We interviewed some of the children and at least 90% said that the harder the force is the higher the rocket will go.

Picture of a rocket when year 6 and recxeption class did a rocket experimentMr Abberton;the year 6 teacher claimed that his rocket went the highest. His rocket didn’t go as high as wanted on his first experiment. The children estimated that the rocket only went 500 centimetres. His second shot went about 30 feet. To be quite frank reception was better than Mr Abberton.

One of the year 6 pupils quoted “It was a very fun experiance and we all loved it!”

 

 

 

Here’s a video of the event.

Are we drinking enough water? A special report.

Tuesday the 22nd of June saw record temperatures in the OLV playground (reaching 22 degrees) and big queues at the water fountain.  We asked if children are drinking enough water to keep healthy?

We sent our reporters out to see how much water the children are drinking.

Surpisingly we discovered that children don’t drink enough water a day,only a small number of children used the water fountain while we were there.

Doctors and teachers recommend that you should drink at least 1.2 litres a day – more in warm weather. (That’s about 8 glasses of water a day!) This could be pure water or orange juice, but is coca cola good enough?  Mrs Jessop says, “you need to drink about 1 to 2 litres of water and juice but no fizzy drinks . ” .
