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!

Winter Wonderings – Why Does Frost Make Patterns?
The third #winterwonderings post from our Science Correspondent, Samantha, we take a look at why frost makes patterns. Many countries have a mythical figure like Jack Frost, who draws in the ice and frost in winter, but what really causes these gorgeous natural designs.
The Girlguide Girls’ Attitude Survey – Written By You
My name is Isla Whateley, I’m a 17-year-old Girlguiding member from Glasgow and a member of the charity’s youth panel Advocate. We discuss issues affecting girls and young women and look for ways to seek change.
Every year, Girlguiding publishes research into the opinions of girls and young women in the UK, called the Girls’ Attitude Survey. The findings from the latest report show that girls and young women are experiencing shocking levels of everyday sexism and discrimination at school, on the street and online.
For example, 75 per cent of girls aged 11-12 say sexism affects most areas of their life, 87 per cent think women are judged more for looks than ability and one in five 7-11 year-olds say they have been on a diet.
Women in Politics: Be The Change You Want To See
Recently the online parenting website Mumsnet ran a survey which found that people in politics are seen to be ‘white, middle-class and male’. We think that ANYONE can become an MP, so we decided to chat to some politicians about diversity in politics.
First up, we wanted to know what it is really like for women in politics. We asked Tina to chat with Heidi Alexander, Labour Minister of Parliament for Lewisham-East in London.
