Winter Wonderings – Are Snowflakes Really All Different?
It’s a common belief that no two snowflakes are the same, and in a way this is true. No snowflake can ever be completely identical to another, because when you get down to the molecular level they will have slightly different kinds of water molecules, different electrons and different traces of other materials such as specks of dust.
However, if we’re talking only about the appearance and shape of a snowflake, then yes it is possible that some will have duplicates. Snow crystals can vary from fairly simple, hexagonal structures to the more complex and delicate shapes that we commonly think of as snowflakes.
The simple flakes have far fewer molecules than their larger cousins and so it’s entirely possible that you could find two that appeared identical when viewed through a microscope. The more complex structures, however, can have more than a hundred different features and each feature can form in a number of different ways. This makes it highly unlikely that you would ever find two large snowflakes that looked the same – but you could have fun trying!

What Makes a Family?
What does the word ‘family’ mean to you? It can mean many things in our society. Some define family as a mother, a father and one or more children. For others, there don’t need to be children in the home for there to be a family. Where there are children, about three quarters of the parents will be married to each other.
In 2013 the Office of National Statistics, which is a government body which takes surveys on all manner of topics to help the government make policy (rules under which we all live), found that there were 18.2 million people living in this type of family. Many more of us have families which have a different make-up. For the purpose of the survey, a family is defined as people living in the same household.
However, as many of you will know, there are other ways in which we describe our family. There are children who have two parents of the same gender, there are children who have only one parent with whom they live, other children have guardians and live with aunts, uncles or grandparents.
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. The water is trapped inside a layer of blue rock called ringwoodite, in the layer of hot rock between the Earth’s core and its surface) that is known as the mantle.
