Life as a Child with a Chronic Condition

A chronic condition means a type of illness or disability which will be a part of your life for the rest of your life, and will mean medication or other type of medical treatment such as physiotherapy (exercises designed to treat and strengthen your body) and regular visits to the doctor or hospital or both.
If you’ve been diagnosed with a chronic condition, it can be scary and upsetting. You may not know what was happening,  and you will probably have lots of questions. We spoke to Tina, who grew up with a chronic condition on what’s learned over the years, and asked her advice on living well with a health condition.

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.

Do You Hate School Uniform? – Written By You

My name is Daisy, I’m eleven years old and although I am English, I have lived in Germany nearly all my life! I speak German and English and can read and write both too. I enjoy writing and listening to music and am the middle child of three. My mother is an author.

Does your school have a school uniform? Having to wear those scratchy skirts? Tight stockings? With our normal clothes, you can show what kind of person you are! You can send a message out to the world with how you dress, what makeup you were and how you have your hair done!

School uniforms are stopping all this. Not being allowed to choose what to wear seems so unfair! Wouldn’t it be fair if we could choose if we wanted uniforms or not? People are debating on school uniforms and deciding if they should stay!
