You may have noticed that you can see your breath when the weather is cold, especially if you exhale really hard. But what causes this and why doesn’t it happen when it’s warm?
Have you ever heard this term and wondered what is the separation of powers exactly, and why is it so important? If so, then read on because we are going to explain it!

Separation of powers isn’t a new idea – in fact, even the Ancient Greeks had a version of this political system, as did the Romans. There are variations in place across the world.
Each country has a slightly different setup, so we’ll use the United States to explain the concept.
The idea behind it is to have a system in place that prevents one person or group from having all the power over an entire country. If you think back to the days when countries were ruled by a king or queen, who made decisions that affected the lives of everyone who lived in their kingdom – sometimes that went well, but often it didn’t. Instead of one person having all the power, a democracy splits the power between different people or groups of people.
When you think of the person who runs the country, you probably think of the President. The President represents the EXECUTIVE branch of the government.
In the USA, that means that the President executes the instructions of Congress, signs Executive Orders, selects judges to be approved by Congress, and is in charge of the armed forces (the navy, army and airforce).
By the way – don’t get confused by the word ‘execute’, which can mean ‘to put to death, to murder’ but can also mean ‘to carry out, to accomplish’. The President carries out the instructions from Congress, he doesn’t kill them all!
Moving to a new school is always scary, whether you’re moving from primary school to high school or into a new school in a different area. What can you do to make it easier?
My kids are old hands at this because they’ve moved school so often, even going into schools in a new country where they haven’t known the language. We’ve lived in Germany, Switzerland and UK and they’ve been to local schools speaking German, French and English. It wasn’t ever easy but they’ve made great friends who they still keep in touch with now that they’ve moved on.
I asked them for their advice on moving to a new school.
Hiccups are caused by the diaphragm (pronounced DYE-uh-fram). This is a large, dome-shaped muscle that sits at the bottom of your chest cavity, below your lungs. When we breathe in the diaphragm tightens, helping to pull air into the lungs, and when it relaxes it forces the air back out again. Sometimes the diaphragm becomes irritated and instead of tightening smoothly it does it in a jerky way, which makes air suddenly rush into your throat. This air is stopped when it hits the voice box and makes the opening between the vocal cords close very suddenly. This is what produces the sound of the hiccup.
