Have you ever sat in a Maths class wondering if you will ever have to do long division without a calculator once you leave school? Or silently cursed your Geography teacher while learning about the formation of oxbow lakes?
And History? That’s all in the past and irrelevant, isn’t it? In this series of articles, we will look at some of the subjects we learn at school, and try and answer the question: What’s the point in learning this?
Last time we looked at uses of Physics, both in day to day life, and in careers. Today we will focus on History – the study of the past and how our society came to be as it is. Here are some ways in which studying History is useful to us:
When we study history we don’t just learn lists of facts and dates off by heart. We read lots of opinions about what happened and why, and come to our own conclusion. We base these opinions on two types of material, primary sources which are texts and drawings created at the time of the history we are studying, and secondary sources which were written after the event.
Do you ever wish you were more confident? Do you watch other kids standing in front of the class, and presenting their work, and wish you be that self-confident kid?
We often talk about self-confidence and self-esteem in tweens. These two are linked, but slightly different. Self-esteem is about how you feel about yourself, how you value your abilities and yourself. Self-confidence is about how you feel about your abilities, about trusting yourself to do something.
You could have a high self-esteem generally, but have low self-confidence in a particular area, e.g. doing maths, or standing in front of the classroom and presenting a book report.
We often split people into ‘confident’ and ‘not confident’, but we can all learn to be more confident. It just takes a bit of practice. Here are our top tips for increasing self-confidence and self-esteem!
Have you ever let go of a helium-filled balloon and let it soar into the sky? Maybe you’ve even tied a message onto the string, with your contact details and hoped that someone would let you know where it landed when it popped. These awesome girls went a big step further than that. They sent a balloon into SPACE, with a couple of Go-Pro cameras attached, in a really cool science experiment.
Do you ever wonder why people can’t pronounce your name correctly? Or struggle to say a friend’s name right sometimes? Here Avani tells us about her experiences, and how we can make the effort to pronounce things as best we can!
Do people always get your name wrong?
My name is Avani and let me start by saying: I get it.
Sometimes I spend ages teaching someone how to say my name properly (Uvni would probably be the best way to write how it’s pronounced) and other times I really can’t be bothered. I wish I had an easier name, or that people would just work harder to get it right!
Why do we find some names really difficult to pronounce and others really easy?
Here in England, people have names which come from all over the world. These names might be from places where a different language is spoken, and the different languages may also use different letters or characters to those we use for English.
My family, for example, come from a part of India called Gujarat. The Gujarati language uses a syllabary (a set of sounds) rather than an alphabet, but the syllables don’t always match up with English letter. The ‘v’ in ‘Avani’ (વ in Gujarati script) should actually be pronounced somewhere in between the English ‘v’ and ‘w’ sounds, but there isn’t an English letter that sounds exactly the same and this makes my name harder for people to remember! Also the ‘a’ and ‘u’ sounds in Gujarati are written using variations of the same symbol (અ (u) and આ (a)), which is why my name is spelt with an ‘A’, but pronounced using a ‘U’. Here’s what ‘Avani’ looks like written in Gujarati: અવનો – cool, right?
Languages which do use the same letters as those in English, may not pronounce all of them in the same way. This means that names that look similar on paper may be pronounced differently depending on where in the world someone lives. In Spanish, for example, the ‘j’ and ‘x’ letters are more like (but not identical to!) the English ‘h’, and in German, the letter ‘j’ sounds more like the English ‘y’ – can you imagine all the different ways people around the world must pronounce ‘Jesus’? You can listen to a few here!
It’s not only names from other countries that are hard to pronounce though! Have you ever thought about which common English names might be tricky for someone learning the language to get their head around? What about the name ‘Thomas’? We say it with a hard ‘T’ (like the one in ‘tree’, rather than the one in ‘three’) even though it is spelt with a ‘Th’, and we say the name ‘Charlotte’ with a ‘Sh’ sound (like in shop) even though it is spelt with a ‘Ch’ (like in chop). It must be hard to keep up with which names follow the usual pronunciation rules (like Theo or Charles) and which ones don’t!
What can I do if I think I’m pronouncing someone’s name wrong?
It is always worth checking with someone if you think you’re saying their name wrong – even if you’ve known them for ages and are embarrassed about asking, chances are they’ll be really glad to have an opportunity to correct you! However, it’s also important to remember that even if you know that the way someone says their name is different to the traditional way of saying it, you should always say their name like they have asked you to. Many people living in England, for example, prefer to go by a nickname or a more ‘Anglicised’ (English-sounding) version of their name to make things a little easier – so if you know a ‘Jesminder’ who prefers ‘Jess’, or a ‘Paulo’ who prefers ‘Paul’, you should respect their decision!
If you’ve just met someone new and have forgotten how to pronounce their name (or even if you’ve met them a few
times) – don’t despair, they probably won’t mind if you ask them again! If you are too embarrassed, though, there is a huge variety of pronunciation websites out there which will be able to help you. Click here for a good one!
Do you have a hard-to-pronounce name? Or have you ever been in an embarrassing situation over getting someone’s name wrong? Do you live in another country – which English names do you really struggle with? I’d love to hear your stories!
As well as trying to get people to say her name right, Avani Shah is currently working on a book for 8-12 year olds. She also blogs about her childhood and teenage experiences (Away with the Mice) and writes about words, etymology, and spelling for a website called Spellzone.
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.
