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.

Egg Box Gardening

I started a little experiment of my own this spring. I wanted to find an easy way of sowing seeds for growing vegetables at home. I have a small veggie patch, but I worked out last year that I could grow a lot more, if only I had  many more seedlings to plant out.

But sowing seeds can be a bit fiddly, and then you’ve got to plant out each tiny plant. That takes a lot of time. I wanted more veggies for less work, so I collected as many egg boxes as I could find, and sowed seeds into each egg holder. The pictures show the planting and growing on of broad beans, but I have also used the egg boxes for runner beans, radishes, beetroots, spinach, tomatoes, rocket, pak choi and patty pans.

And it’s not too late to start growing your own right now. You don’t even need a veggie patch in the garden; plant the egg boxes into a pot or container for your window sill or patio.

The Doncaster Book Awards – By Kids for Kids

Doncaster Book Awards Shortlist 2018

There are lots of children’s book awards, but the Doncaster Book Awards is special. That’s because children decide not only which books they want to win, but even which ones are on the shortlist.
Doncaster is in Yorkshire, in the north of England. Lots of schools in the area, alongside many home-educated kids, register and take part in the awards. First, the children select the shortlist for different categories of books, and these are then voted on by all the schools and the children. Sometimes book publishers ask to get their books on the list, but the answer is always no. This one is by children, for children!

Stories From The Stables – Sam

This is first of a series of Stories From The Stables, by Carolyn Ward.
I fell off, honest 

Learning to ride is a fabulous hobby.  It can be pricey, but you can borrow a hat and crop from most stables, and start off in trousers and strong shoes.  It is great exercise, very exciting, and teaches respect for animals, balance, and correct posture.

When I was very young I rode at Stourton Stables, a children’s riding school where the ponies were mostly grumpy and had to be separated in the fields for fear of kicking each other to pieces.

Oh, happy riding lesson days. Hours spent in icy pouring rain, in snow, in fog, and even more rarely; in lovely sunshine.  The best riding times of year for me were spring and autumn, before and after the major insect season.
