What Is a Raspberry Pi… and How Does it Work?
You may have heard of a Raspberry Pi – a credit card sized computer that plugs into your keyboard and monitor – but exactly what IS a Raspberry Pi, how does it work and what can you do with it?
12 year old Elspeth takes a closer look at the mini-computer and explains how even young kids can use it to learn how computers work and how to code.
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!

The Ultimate Guide for Kids to Pack Your Own Suitcase
Welcome to our ultimate guide for kids to pack your own suitcase!
When I was a kid, my parents were Scout leaders and one of their rules was that kids should pack their own suitcases. My mum always said that if the kids packed themselves, they knew what they had in their bag or rucksack and how to find things. And they were able to pack to go home.
Now I have my own kids, I can see exactly what she meant. My kids have been packing their own suitcases since they were little. In the beginning, I’d check to ensure that they didn’t have 12 t-shirts and one pair of trousers for a week-long holiday but now I just remind them to take their toothbrush and any vital pieces of kit.
