Winter Wonderings – Why Can You See Your Breath When it is Cold?

This is the first in a series of posts by Sam Gouldson called Winter Wonderings. Sam will take a closer look at some of the amazing things that winter brings, such as snowflakes, ice and snow and explain the science behind the season!

You may have noticed that you can see your breath when the weather is cold, especially if you exhale really hard. But what causes this and why doesn’t it happen when it’s warm?

Jump! into Etymology for Kids

Have you ever thought about languages, and how they develop over time?
Why do we say ‘tree’ when we look at a one of those green things outside our window, and where did the word ‘rose’ come from? (Can you tell that I am looking out of my window for inspiration?)
When we look at the links between the words that we use in English and those in a different country, we often find similarities. Information is the same in English, as in German and French, although the pronunciation is different.
The study of words is called etymology, and today Millie is going to explain a bit more about this, and tell us a bit about the word ‘JUMP’.

Where Does the Word Candidate Come From?

Today is election day in UK, when the citizens of the country choose their new government. You can read all about how the elections work here. You wouldn’t think that dress codes of ancient Rome would affect the elections of today, but they do! Millie Slavidou explains.

Today is a good day to think about the word ‘candidate’. I rather like the etymology of this one.

It comes from Latin candidus, which is the past participle* of candidare, which meant ‘to make white, to make bright’.

Not because of whitewashing whatever the candidates might have said or done! It was because in ancient Rome candidates who wanted to be elected either to the Senate or any other office wore white robes.

If we take it one step further back, to a root meaning ‘white, shining’, we find that ‘candle’ is a cognate.**

 

*Past Particle

The past particle is the past form of the verb that can also be used as an adjective, like “a fallen tree”. In the case above, the adjective is like saying ‘whitened’ in English. Other examples of past particles are:

verb: bite
past particle: bitten
example: a bitten apple

verb: choose
past particle: chosen
example: aa chosen present

verb: crash
past particle: crashed
example: a crashed bicycle

 

**Cognates

A cognate is a distant relative, a word ultimately from the same root. Like a third cousin. Here are some examples of cognates.

 

14126405243_c179f6f9b8_qBook is related to beech. Well, actually, book means beech! Both come from Germanic word meaning beech tree, Buche.

Germanic runes were originally inscribed on tablets made of beech wood. Modern German for book is Buch!

 

2400500463_67988839f0_qWOOL and FLANNEL are distant cognates.  Today, fashion stores often describe plaid shirts as ‘flannel’, but it is actually a soft woven fabric, originally made of wool, but now often cotton or synthetic. You might have a flannel pyjamas, which are lovely and cosy in the winter!
The word wool is from a Proto Indo European root *wele meaning ‘wool’.
 In Welsh, the word gwlanen, means ‘wool’ and is from the same root. The word flannel comes from the woollen vests that were made, presumably by Welsh traders from Welsh sheep –  Gwlanen became fwlanen, and then flannel. So wool and flannel are distant cousins!

You will often find the word ‘candidus’ used in botany or biology to describe something that is white, such as crocus candidus or the white woodpecker Melanerpes Candidus. There is even a white monkey called Propithecus candidus.

A Homemade School

Dr Lesley Beeton visited South Africa and visited a school to find out what it’s like to go to school in South Africa.

This is the Drakensberg in South Africa. In English, it means ‘Dragon Mountain’. The children in this part of South Africa face a daily commute to school. In the area where I was staying, the nearest town was Bergville. With the windy roads through the mountains, this journey can take almost an hour. School starts early too, at eight o’clock, so that means getting up around 6 am to be ready for the taxi.

What is the Point in Learning Chemistry?

learning chemistry

Have you ever sat in a Maths class wondering why you will ever need to be able to do long division without a calculator? 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… Chemistry?
