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!

Water and Engineering – Water, Wonderful Life
Dr Lesley Beeton is a scientist, who studies what the DNA code tells us about human life and health. She has always loved science, and believes that science doesn’t just happen in laboratories. It happens all around us. Science keeps aeroplanes flying, electricity flowing, and the internet speedy.
Dr Beeton grew up in South Africa. Some of you may have traveled there for your holidays, to see the game reserves or Table Mountain. But even if you haven’t been there, we can all still learn something from the experiences of southern Africa.
