The UK General Election – An Explanation for Kids

Every five years, United Kingdom elects a new parliament. This is called a General Election and it’s pretty complicated. If you’ve ever wondered how a country decides who is going to run things, this is how! We asked our contributor Tina Price-Johnson to write an explanation of the General Election for kids.

When I was in Year 9, my school ran a mock general election, so we could learn how an election works.  I was chosen to be the Liberal Democrat candidate, and two other students were chosen to represent the Conservative Party and the Labour Party.  We didn’t have any other parties at that time!

We had to pretend we were running to be elected as a Member of Parliament (MP), and the other students in the school were the voters.  We created posters and learned what each party stood for, so we could debate in front of the whole school and give our speeches.  We spoke to students in the hallway, and each of us had a team of other students to help us out.  This is exactly what all the candidates for MP in your local area will be doing. More or less!

Early English – The Latin Alphabet

In our last post, we discovered the runic alphabet and the Futhorc, and now we are going to look at what came next. The Latin alphabet.

The Futhorc was gradually replaced by the Latin alphabet. However, it seems that the Latin alphabet was not perfectly suited to represent English, which contained sounds that did not exist in Latin, and so people adapted it with the addition of a few runes: thorn to represent ‘th’ and wynn to represent ‘w’, as well as a few adaptations in usage of the already existing Latin letters in order to make them better suited to representing English sounds.

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

Volta's Voltaic Pile, the first electric batteryThis 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.

Who Invented Denim Jeans?

If you’re anything like me, you’ll live in denim jeans when you’re not at school– they’re comfy, practical and come in loads of different styles, colours and designs. I’ve also got a denim jacket, which is perfect for throwing on over dresses when it’s cold outside. Even denim gilets come in and out of fashion on a pretty regular basis.
I think it’s pretty safe to say that denim has become something of a wardrobe staple over the years and in fact, I don’t really know what I’d do without it. But jeans haven’t always looked the way they do now and trends have changed a lot over the years.

Have you ever wondered…about your teeth?

Have you ever had a tooth pulled out by a dentist? If you did, you may have noticed something odd. The roots were probably still attached to the tooth, unlike when a tooth falls out normally. What happens to the root of a tooth, how do teeth grow and why is it important that you take care of them? Samantha Gouldson investigates!
