Science News For Kids – Water Found on Mars
Until 3 billion years ago, Mars was a wet planet much like Earth. It had land, an extensive atmosphere and an ocean that covered two thirds of the northern hemisphere as well as smaller bodies of water. But significant climate change caused the water and atmosphere to boil away, leaving Mars a dry and arid planet. Or so we thought… then came the news from Nasa – Water found on Mars!
Who Was Margaret Thatcher?
If you have been listening to the radio, or watching the news today, you may have heard that a woman called Margaret Thatcher has died.
You might not have heard of Mrs Thatcher – or Baroness Thatcher to use her correct title – but if you live in Great Britain, your life has been affected by her. Some adults find it amusing or shocking that tweens and teens haven’t heard of her, because she was such a large part of our lives when we were growing up. It is strange for us to realise that she is ‘History’ to you, not current ‘Social Studies!
So, who was Baroness Thatcher, and why is everyone talking about her death?

How to Be an Inventor
Have you ever thought ‘There MUST be an easier way to do this’? If you have, you are not alone. People around the world invent and re-invent products all the time. Some of them are professional, and inventing is part of their job. Others are just normal people who had a bright idea.
There are many clubs and societies which you can join and learn to invent or develop your curiosity and talent for science and invention. All inventors start somewhere, and most of them start when they are very young. Young people have the best imaginations so if there is something you think is a good idea and you want to try and create, why not join up with other young creative people and work together.
Shooting stars, Weather, and Rocks falling from the Sky!
What do shooting stars, weather and rocks falling from the sky have in common? Are you wondering whether we have gone mad asking such a question? Do rocks ever fall from the sky? Of course they do! You might know them better as “meteorites”, and they are meteors, or rocks from outer space, that fall down to the earth. And what does that have to do with weather? It’s not like they come down like rain! And before you say to yourself “meteor shower”, remember that a meteor is actually a shooting star, a space-rock that burns up in the Earth’s atmosphere. Related, yes, but weather, no.
The weather connection is through another word, generally used to mean “study of the weather”. That word is “meteorology”. As you can see, all three have something in common – the word “meteor”.
So what is this word, and how did it come to mean these different things?
Meteor came into English through French in the late 15th century. In French it was meteore. Very similar, you might think. Does this mean that it is a French word. Not at all. The next question we must ask ourselves is where did French get it from? The answer is from Medieval Latin meteorum, which meant “things in the heavens”. But this is not the end of the tale. Latin took the word from ancient Greek, and in Greek we can analyse the word to see what it really means.
The Greek word μετέωρα (meteora) can be broken into two parts: meta, which means “over, beyond” and aora, which comes from the verb αείρω/ αίρω (aeiro, airo), which meant “to raise, lift up”. Even today, in Modern Greek, αιωρείται (aioreitai) means “it hovers”. All this means that the original meaning of the word was “thing that is raised in the air”. And even in ancient times this developed to mean “things in the sky” and gradually came to have the meaning it does today.
Another interesting point is that the word “air” is in fact from the same root as αείρω (aeiro), which makes it a distant cousin, or cognate, of “meteor”.
Did you know:
One of the largest and most famous meteor craters is to be found in northern Arizona, desert of the U.S. It is 1,200m wide, 170m deep and calculated to be created 50,000 years ago! It is more commonly known as the Barringer Crater.
