How to Clean Water
With poor living conditions and water shortages increasing every year across the world, the question of how to clean water efficiently is becoming ever more important.
Does Everyone Have Clean Water?
When you have clean, safe water available at the turn of a tap it’s very easy to take it for granted. But almost 750 million people don’t have access to clean water; that’s one person from every ten in the world’s population. There are many reasons for this, from poverty to poor management by governments.

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?
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’.
Winter Wonderings – Are Snowflakes Really All Different?
It’s a common belief that no two snowflakes are the same, and in a way this is true. No snowflake can ever be completely identical to another, because when you get down to the molecular level they will have slightly different kinds of water molecules, different electrons and different traces of other materials such as specks of dust.
However, if we’re talking only about the appearance and shape of a snowflake, then yes it is possible that some will have duplicates. Snow crystals can vary from fairly simple, hexagonal structures to the more complex and delicate shapes that we commonly think of as snowflakes.
The simple flakes have far fewer molecules than their larger cousins and so it’s entirely possible that you could find two that appeared identical when viewed through a microscope. The more complex structures, however, can have more than a hundred different features and each feature can form in a number of different ways. This makes it highly unlikely that you would ever find two large snowflakes that looked the same – but you could have fun trying!
