Six Ace Classroom Gadgets You Won’t Want to Miss
There’s no getting around it – school can sometimes feel like a drag. We’re willing to bet that some of these cool gadgets and new technology would make school life much easier!
Under the Sea with the RRS Discovery
Last month the The RRS Discovery, the most advanced research ship was launched in Southampton.
At £75 million it is one of the most expensive research ships ever commissioned. It measures at just over 100 metres long, with seven main laboratories and a bridge like the Starship Enterprise! It has just begun expeditions around the British Isles, currently examining the UK’s continental shelf, a band of sea floor around 50m-100m deep.
“These shelves are really very important,” says Dr Sanders from the National Oceanography Centre in Southampton. “There is a lot going on in the shelf seas and we need to understand how they work so we can safeguard their future.”
A Kid-Friendly Explanation of The Big Bang & An Amazing New Discovery by Scientists
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.

Why DO Kids Want to Play Minecraft?
Sitting back, ready for another interesting and rather aggressive night on COD (Call of Duty), I launch my dashboard to see the usual suspects all gathered playing the latest shoot ’em ups.
Except one. Looking again, I notice my 13-year-old brother Jimbob is playing a game I’ve never seen – MINECRAFT.
After much persuasion and explanation “COME ON BRO, BUY IT PLEASE, YOU BUILD STUFF”, I decide to purchase it, in order to support him in our mum’s campaign to play online more responsibly.
The game launches and all I see is blocks. Have I got the right game? Where are the graphics?
Wandering mindlessly around, past trees, rivers and spiders, until Harvey Jimbob asks me to come to his house. Here’s the strangest part: he built it.
What is the Orionid Meteor Shower?
This October Earth will be passing through the tail of Halley’s comet, which will mean a shower of meteors flashing across the night sky. Our science editor Sam Gouldson explains.
What is Halley’s Comet?
A comet is a lump of rocky particles, ice and dust all bound together like a dirty snowball. When the comet nears a star, its surface transforms from a solid to a gas. The star’s light shines through these gases and makes them visible to observers as a fuzzy cloud around the comet’s centre, and a tail streaming out behind.
