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.

Facebook For Kids – Good or Bad?

Do you use Facebook? While it is officially banned for under 13 years, a survey last year showed that almost half of Britain’s pre-teens have a Facebook account. Joanna Bradey tells us what she likes about Facebook.

 

Facebook: What’s it all about?

 

Facebook is a website created in 2004 by a US college student Mark Zuckerberg. It started off as a way of college students to network with each other, which quickly spread throughout the world, and now has millions of members. Facebook works by people registering and creating a profile for themselves, and then becoming ‘friends’ with other people. A user can update their status to let their friends know what they’re up to, upload photos to share, send private messages to each other, and play games.  You need to be at least 13 years old to be a member, and Facebook is banned in some countries altogether, like Syria and Iran.

The thing that I like about Facebook is that it is a quick and easy way to keep in touch with all those people I have met in real-life but don’t have time to write to or call them, like old workmates or family that have moved away. I can upload a photo and anyone I am friends with can see it, and comment on it. In the days before Facebook, if I wanted to share a photo with everyone, I would have to print out lots of copies and send them in the post, which is very expensive and time-consuming. Since I joined Facebook, I am better at communicating with people and I enjoy seeing what all my friends and family are doing. I think that I know them better and it’s easy to keep-in-touch.

6 Things Kids with Special Needs Wish EVERYONE Would Do

When we published our article 6 Things Parents Wish Their Kids Would Do … and 6 Things Kids Wish Their Parents Would Do, one of our readers got in touch to say we should do one for the things that kids with special needs wish EVERYONE would do. So we asked our followers, and came up with this list.

It was a bit tricky to put the list together, because there are so many different kinds of “special needs”. For some children, their disability is quite well manageable with medication, or with assistance and therapy, and you’d hardly know they had any additional needs.  You may have heard of autism or Asperger’s Syndrome – these are part of the autistic disorder spectrum, a range of conditions that affect how people communicate and relate to people around them. You can’t tell by looking at someone if they have ASD.

Other children have disabilities that are apparent when you meet them, such as those with Down’s Syndrome, which we have covered in more detail here. Or they might use a wheelchair to get around.

What thing do they all have in common? They sometimes get asked really silly questions, and get treated badly by people. Make sure you aren’t one of them, by listening to what the kids (and their parents) had to say!

Girls Don’t Need No Education

‘WHAT?!’,I hear you cry. ‘Of course we need education!’ And you are absolutely correct.
Sadly in some areas of the world, this is not seen as a basic human right. Children, especially girls, are denied access to schools.
I am sure you have all heard of Malala Yousafzai, the young education campaigner from Pakistan who was shot by people who do not agree with her campaign for girls to be educated.
Malala is carrying on a fight for education that other countries have already fought and won. Tina explains how girls in her home country, United Kingdom, were once forbidden from going to school and when this changed.
