Fact or Fable? Most body heat is lost through the head
Many people believe that you should keep your head covered during cold weather, as most body heat is lost through the head. It’s certainly true that any part of your body that’s exposed to cooler air will lose warmth; heat always moves from something warm to something cooler (that’s called the second law of thermodynamics). And our heads and faces are more sensitive to changes in temperature than other parts of the body.
The Cage of Society
What do you do when you see someone being bullied? And what happens when the bullies are your friends? These were the questions that were occupying the mind of 11 year old Kirsty. Here’s her story.
Not so long ago the only thing on my mind at school was to fit in with my friends and to feel like part of a group.We were a very close circle and I was positive that they were the most loyal, kind and caring friends I could wish for. However, there was one thing that concerned me, their behaviour towards a boy named Ryan.
POO-EE! Roman Toilet Seat Found Near Hadrian’s Wall
How would you like to root around in a 2000 year-old toilet?! The Romans created aqueducts, newspapers, and bound books… but did you know they helped create the toilets we have today?
Archaeologists at a Roman excavation site in Northumberland have recently uncovered a wooden toilet seat…that is 2000 years old! While it looks a bit more basic than the toilet seats we have today, it shows that they were very concerned with cleanliness.
The Roman wooden toilet seat. Not looking bad to say it’s 2000 years old! (Source.)
Movie Making Camp for Girls – Camp Reel
Have you ever thought about the people who make movies? Did you know that less that 20% of the main decision making positions in the media are held by women? This obviously affects the way that women and girls are portrayed on screen.
With media platforms like YouTube or Vimeo, its easier to get friends together and write, direct, edit your own shows and distribute them for the world to see, but where do you start? How can you make a movie? One way is to take part in a Apple Camp – check the link to see if there is one in your area.
Once you have been making films for a while, you may want to learn more about how movies are made, and how to put them together. A new venture in California aims to help girls do this – on a one week camp.
Our contributor Annie May had a chat with Esther from Camp Reel to find out more.
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.
