A YouTube History Lesson for Kids – The Berlin Wall
What was the Berlin Wall, and why was the fall of the wall so exciting – not only for Germans but for people around the world?
To understand the importance of this event, we take a good look at the news archives, in a YouTube Kids’ History Lesson – The Berlin Wall.
Have You Been ‘As Good as Gold?’
In the run up to Christmas, children are often asked if they have been ‘good’. Perhaps you have answered ‘I have been good as gold’, but do you know where that simile comes from?
Who Invented the First Electric Battery?
When we talk about electric batteries, we often talk about voltage. But did you know that this word is named after the person who invented the first electric battery? First, let’s take a look at what a volt is, and then we’ll find out more about the guy who gave the ‘volt’ its name.
What is a Volt?
A volt is defined as a unit of electric potential and electromotive force, and voltage refers to the number of those units. That sounds a lot more complicated than it is! If you think of the water in a tap being like the electricity running through a wire, the voltage means the amount of pressure. This video is quite long but explains it very well.
Why are Volts Called Volts?
Alessandro Volta
The term actually comes from a name. It was coined in honour of Italian physicist Alessandro Volta, who is recognised as the inventor of the first electric battery. During the 1790s, Volta worked on the theories of electricity of the day.
Volta disagreed with the theory proposed by fellow Italian scientist Galvani that electricity was generated by animal tissue. Instead of experimenting on frogs or other animals, Volta did experiment after experiment with metals.
His persistence paid off, and in 1800, he invented the world’s first battery, known as the ‘voltaic pile’.
The Voltaic Pile
This voltaic pile was simple but ingenious. It consisted of a pile of zinc and silver discs. But alternating between them was a piece of cardboard, or a piece of cloth, that had been soaked in saltwater.
There was a wire that connected the zinc disc on the bottom to the silver disc on the top, and this wire was capable of producing sparks.
What else Did Volta Invent?
The invention of the first electric battery brought Volta the most fame and recognition, but he also made other discoveries. He invented the electrophorus, a device that could transfer an electrical charge to other objects, as well as an electrical condensor, and the voltaic cell.
He is also known for having discovered and isolated methane gas. After his death, the volt and voltage were named in his memory.
What about Galvani?
Luigi Galvani
Yet there is one more twist to the tale. Volta’s longstanding colleague Galvani of the animal electricity theory also left his name in our language. When we say ‘galvanise’ or ‘galvanism’, that is where it comes from.
Despite their differing theories, there was no rivalry between the two scientists. They were both more concerned with the pursuit of knowledge than with whose theory would prove to be right, and it was Volta who first coined the word ‘galvanismo’ in Italian.

Ailsa – Our ContiReporter at Women’s U17 EUROS – Day Two
Tuesday 26th of November
Today was match day! England v Italy.
The match was at Telford Stadium so we had a 50 mile journey from St. Georges Park to get there.
It was a rather cold day to be outside but it wasn’t shown by any of the excited school children that flooded the ground, ready to watch the game. Before the match began outside the stadium, Continental Tyres were running a Conti Fan Zone. A variety of football activities were being run for the energetic children.
I had a go at measuring the speed of my kick. On my first go I fluffed it and didn’t even hit the target (that’s why I play in goal!) but on my second go I managed to get 29mph which was quite good.
I had to do a piece to camera about what went on before the match and interviewed two Birmingham City Ladies who were taking part in the activities.
Me and my cameraman David positioned ourselves by the team dugouts, ready and waiting for kick off. When the game finally kicked off it was a fast, exciting game.
Both teams were equal and no team was particularly dominant. The England captain, defender Leah Williamson was a stand out player as she was clearly comfortable on the ball and lead the team with ease.
At half time it was 0-0. For the second half me and David retreated to the press box, due to the days coldness, where Simon and Dad had been watching the game and famous footballer spotting.
I had to do some reporting to the camera at half time about how I thought the match was going. The second half was just as gripping and as nail-biting as the first. Unfortunately England conceded an untimely goal off a deflection. England continued to battle throughout the second half and continuously tried to win themselves back a goal, they came staggeringly close to scoring again but unluckily when the final whistle blew, Italy won 1-0.
The score didn’t reflect the game, a draw would have connoted the game more suitably. After the game, I got the chance to ask Lois Fidler a question at the after game press conference.
Following the press conference I then got the opportunity to interview the current England Ladies Manager, Brent Hills, who was lovely and chatty, I still can’t believe I got the chance to interview him.
I was also fortunate enough to be able to interview Alex Scott, England international, Dave Sampson, Bristol Academy Ladies Manager and four of the Under 17 girls, Leah Williamson, Keira Walsh, Chloe Kelly and Molly Rouse.
I was overwhelmed by the people I got the chance to talk to about the game. As the day came to a close it was time for us to go back to St. Georges Park after a long, jam-packed, thrilling day.
