How Much Sleep Do Kids Need?

Julianne Robertson investigates the world of snoozes, forty winks, cat naps and snoring. What is SLEEP, why do we need it, and how much sleep do kids need?

 

A couple of nights ago I was feeling really, really tired, so I went to bed early.  I slept soundly, without even dreaming, until about 5am, when I woke up.  It felt like I’d only been sleeping for about 5 minutes!  After that, I fell back to sleep but had lots of vivid dreams and when I woke up a couple of hours later, it felt like I’d been asleep for a long time.  After all that I still felt well-rested and was ready for the day.

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…

Is The Great Wall of China Visible from Space?

The idea that the Great Wall of China can be seen from space has been around since at least 1938 and is still popular today. It certainly seems plausible that such a large, linear structure would stand out from the surrounding landscape, but it’s actually not true.

Alan Bean, the fourth man to walk on the moon, said in 1969

“The only thing you can see from the moon is a beautiful sphere, mostly white, some blue and patches of yellow, and every once in a while some green vegetation. No man-made object is visible at this scale.”

But if you can’t see the Wall from the moon, how about somewhere closer to Earth? The International Space Station (ISS) maintains a low earth orbit of between 330-435 km above our planet’s surface.

CURIOUS CREATURES 2 – The Stag Beetle

 

The strangest creatures are, to me,

The ones I love the best.

The creepy, crawly and the odd

Are cooler than the rest…

 

These magnificent beasties are the armoured vehicles of the insect population and the largest terrestrial-dwelling beetles in the UK. Their common name is a reference – unsurprisingly – to their antler-shaped “mandibles” or jaws, which they use to fight over territory, but not, perhaps surprisingly, to win the respect of female Stag Beetles..!

 

These Curious Creatures have intrigued me ever since I found an expired female stag beetle (see below ) in a south-west France many years ago. I drew it next to a blackbird’s feather, captivated by the different tones of black, the textural contrasts and inky depths of colour. I found it – and still find them all as a species – fascinating and beautiful, particularly the males, with their extraordinary maroon-red mandibles.

Is Black Really White?

black and white

Science will tell you that black is not a colour, rather it is the absence of colour or the fact that there is no colour there. I expect that makes you think of white, rather than black!
And that’s the interesting thing about the word black: it was nearly white. And in fact in several other languages, the same root did develop to mean white.
