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 Causes Motion Sickness?
Motion sickness is also known as travel sickness, sea sickness or air sickness. It can happen in a number of situations, not all of which involve movement, and is a very unpleasant sensation. As part of our Have You Ever Wondered series, our Science Editor Sam finds out what causes motion sickness, and if there is anything you can do to prevent it.
Under the Sea with the RRS Discovery
Last month the The RRS Discovery, the most advanced research ship was launched in Southampton.
At £75 million it is one of the most expensive research ships ever commissioned. It measures at just over 100 metres long, with seven main laboratories and a bridge like the Starship Enterprise! It has just begun expeditions around the British Isles, currently examining the UK’s continental shelf, a band of sea floor around 50m-100m deep.
“These shelves are really very important,” says Dr Sanders from the National Oceanography Centre in Southampton. “There is a lot going on in the shelf seas and we need to understand how they work so we can safeguard their future.”
Good Relationships – Healthy Relationships – Tips for Kids
Relationships are hard at any age. Remember that we don’t just talk about relationships when we mean a boyfriend or a girlfriend – it’s about how you get on with your parents, your friends and other people important to you.

Communication

Communication is the most important aspect of any relationship. Sharing things with people in your life is important. We do this mostly by speaking and listening. It is important to share how you feel about things and to listen and try to understand how others feel about things (this is called empathy).
How good are you at both talking AND listening? If you favour doing only one of them in a relationship then this isn’t as balanced as it could be- you probably need to work on doing both and so should the other person.
Also sometimes people might say something but their body language (how someone uses their body or their facial expression) maybe saying something different. Take some time to consider what is your body language saying when you talk? What is their body language saying? Do you make eye contact when you talk?
A key to successful communication is to use “I” statements instead of “you” statements- eg. “I feel sad when you call me silly” is better than “You calling me silly makes me sad” because the second one can put the person on the defensive straight away and the conversation can go badly after that.
