SCIENCE NEWS – Discovery of An Underground Ocean

 

 

Earth’s Underground Ocean

 

In 1864 the French author, Jules Verne, published his novel “Journey To The Interior of the Earth”. In this book 3 men explore volcanic tunnels that lead miles beneath the Earth’s surface, and have a number of strange encounters along the way. One of these is the discovery of a massive ocean, deep underground. Now, 150 years later, it seems that Monsieur Verne’s imagination may have been more accurate than he knew.

An enormous reservoir of water, roughly 3 times bigger than all of the Earth’s oceans put together, has been detected 400 miles below the surface.

All this made me wonder – what IS sleep?  Why is it that some nights we feel like we’ve had a really good nights’ sleep, while other nights we still feel tired when we wake up in the morning?  Here’s what I’ve discovered about sleep…

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?
