A Kid-Friendly Explanation of The Big Bang & An Amazing New Discovery by Scientists

kid-friendly explanation of Big Bang

Most scientists believe that the Universe began in a Big Bang around 14 billion years ago. The entire Universe was inside a bubble thousands of times smaller than a pinhead, and was hotter and denser than anything we can imagine.

When the explosion called the Big Bang happened, the Universe as we know it was born. In a fraction of a second, the Universe grew from smaller than a single atom to larger than a galaxy. It kept on growing, and is still expanding today.

Now researchers in America think they have found traces left in the sky that prove this that the Big Bang did really happen. It takes the form of a distinctive twist in the oldest light detectable with telescopes. These twists of light are called ‘gravitational waves’ – the effect is a little bit like how waves form on the surface when you drop a big stone in a pond. However, you also have to imagine that the Big Bang formed the pond itself.

 

 

The team leading the project, known as BICEP2, has been using a telescope at the South Pole to make detailed observations of a small patch of sky. The aim was to find evidence of ‘inflation’ – the idea that the cosmos grew rapidly in its first trillionth, or trillionth of a trillionth of a second – growing from something unimaginably small to something about the size of a marble.

The leader of the team, Prof John Kovac of the Harvard-Smithsonian Center for Astrophysics said:

 

“This is opening a window on what we believe to be a new regime of physics – the physics of what happened in the first unbelievably tiny fraction of a second in the Universe.”

 

Over the coming years, scientists will work hard to investigate every aspect of this discovery. Other experiments will be carried out to see if they can replicate the findings of the American team. If this research is confirmed, it will be one of the greatest scientific discoveries of our time.

Lots of Socks for World Down Syndrome Day

Do you sometimes wear non-matching socks? When you can’t find ones to match or just because you want to?  Well on the 21st March you have the perfect excuse to and Agi is going to tell you why.
Agi has been making videos about her life with her little sister, who just happens to have Down Syndrome, for many years. We asked her to tell us more about this condition, and about life with Magdalena and to share some of her videos with us.

 

Firstly though who am I?

I’m called Agnieszka (Agi for short) and I am home educated with my little sister Magdalena, who is 7 years old. I have a website which I blog on about our life together and anything else I am interested in. I want to be a filmmaker when I’m older, and you can view lots of films that I’ve made on my website, and Magdalena wants to be an artist. She is one of my best friends. We have loads of fun together, and I don’t treat her any differently or treat her ‘specially’, even though she happens to have Down’s syndrome. Which is where the lots of socks come in…but first, let me explain.

I would never have known this unless my little sister, Magdalena was born with an extra 21st chromosome.

Have you worked out yet why World Down Syndrome day is on the 21st of March?

It’s because people with Down syndrome have three chromosomes on chromosome number 21, instead of the usual two. This is also known as Trisomy 21.

Why is it Called Down’s Syndrome?

So why call it Down’s syndrome? No, it’s not because people with Down’s syndrome are ‘down’ or grumpy, it’s actually because Dr John Langdon Down discovered the condition, and it was named after him.

Lot’s of people my age don’t know what Down’s syndrome is, (actually lots of adults don’t either) and that can make them scared of what they don’t know about, so they ignore Magdalena or talk ABOUT her instead of TO her or say something unkind thinking she won’t understand or be hurt by it. So before I get onto the socks, I want to tell you a bit about what Down’s Syndrome is and what it isn’t!

Do Earwigs Really Live in Our Ears?

do earwigs really live in our ears

There has long been a myth that earwigs use human ears either to lay their eggs or to live in and feed off our ear wax, or other similar things. It sounds pretty gruesome, doesn’t it? After all, who would actually like the idea of an insect living inside their ear? But do earwigs really live in our ears?

Fortunately for us, it is not true. Despite their name, earwigs don’t actually live in our ears and neither do they use them to lay eggs. They much prefer their normal habitat of nests under rocks and logs or in flowerbeds. So where does the earwig get its name?

 

Old English Origins

Yet the name itself suggests that this has been a myth for a long time, so let’s examine the name. It can easily be split into two parts: ear and wig. These two parts both come from Old English; which is what we call the language as it was spoken when it was first written down, right up to the tenth century. So this would include the period of Kind Alfred the Great; he of the burning cakes.

In Old English, the words were eare and wicga. The first part, which you can recognise quite easily, meant ‘ear’. But the second part, wicga, meant ‘insect, beetle, worm’. The interesting thing is that it came from a root that did not have anything to do with insects at all, but instead meant ‘wiggle’.

Think about how even today we say ‘wiggly worm’; or think about how you would describe the movement of a caterpillar. You can see how this word came to be associated with insects. So if we put the two parts of our word together again, we have ‘ear-insect’. It seems that our very early linguistic forebears did indeed believe that earwigs lived in the ear.

Blame it on the Romans

But where did this myth that they dwell in our ears come from? It is not unique to English; in German it is known as Ohrwurm, or ‘earworm’, and it is the same in Welsh with pryf clustiog; while in French it is perce-oreille, or ‘ear-piercer’.

To find the origins of the myth, we have to go back in time all the way to the days of the Romans. In around 77 CE, Roman naval commander and writer Pliny the Elder published his work Historia Naturalis, or Natural History.

In it he writes about a great deal of the natural world, including insects. It is here that the myth may have begun, as he writes about earwigs getting into the ear. Perhaps he saw one that had happened to go into the ear by chance, much as a fly or a spider might, and jumped to the wrong conclusions.

The Pincer Insect

Other languages have taken the name from the apearance of the insect; in Italian it is known as forbicina, and in Spanish it is tijereta, while Greek has ψαλίδα [psalida] All three of these translate as ‘little scissors’, deriving from the pincers that the earwig uses to catch its prey.

Ailsa – Our ContiReporter at Women’s U17 EUROS – Day Two

 

 

Tuesday 26th of November

Today was match day! England v Italy.

The match was at Telford Stadium so we had a 50 mile journey from St. Georges Park to get there.

It was a rather cold day to be outside but it wasn’t shown by any of the excited school children that flooded the ground, ready to watch the game. Before the match began outside the stadium, Continental Tyres were running a Conti Fan Zone. A variety of football activities were being run for the energetic children.

I had a go at measuring the speed of my kick. On my first go I fluffed it and didn’t even hit the target (that’s why I play in goal!) but on my second  go I managed to get 29mph which was quite good.

I had to do a piece to camera about what went on before the match and interviewed two Birmingham City Ladies who were taking part in the activities.

Me and my cameraman David positioned ourselves by the team dugouts, ready and waiting for kick off. When the game finally  kicked off it was a fast, exciting game.

Both teams were equal and no team was particularly dominant. The England captain, defender Leah Williamson  was a stand out player as she was clearly comfortable on the ball and lead the team with ease.

At half time it was 0-0. For the second half me and David retreated to the press box, due to the days coldness, where Simon and Dad had been watching the game and famous footballer spotting.

I had to do some  reporting to the camera at half time about how I thought the match was going. The second half was just as gripping and as nail-biting as the first. Unfortunately England conceded an untimely goal off a deflection. England continued to battle throughout the second half and continuously tried to win themselves back a goal, they came staggeringly close to scoring again but unluckily when the final whistle blew, Italy won 1-0.

The score didn’t reflect the game, a draw would have connoted the game more suitably.  After the game, I got the chance to ask Lois Fidler a question at the after game press conference.

Following the press conference I then  got the opportunity to interview the current England Ladies Manager, Brent Hills, who was lovely and chatty,  I still can’t believe I got the chance to interview him.

I was also fortunate enough to be able to interview Alex Scott, England international, Dave Sampson, Bristol Academy Ladies Manager and four of the Under 17 girls, Leah Williamson, Keira Walsh, Chloe Kelly and Molly Rouse.

I was overwhelmed by the people I got the chance to talk to about the game. As the day came to a close it was time for us to go back to St. Georges Park after a long, jam-packed, thrilling day.
