What is Separation of Powers?

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.

What is the Separation of Powers?

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!

What is Juno?

There has been a lot of excitement about the Juno probe this week, but what is it and what is its mission?

What is Juno?

Juno is a spacecraft designed and operated by NASA, the US space agency. It was launched from Cape Canaveral on the 5th August 2011 and has taken almost 5 years to travel the 716 million kilometres to Jupiter, the largest planet in our solar system. Juno is 3.5 metres in height, and when its solar arrays are extended it’s more than 20 metres across. These arrays are covered in more than 18,500 solar cells, which allows Juno to operate even when it’s at such a great distance from the Sun.

Why is it called Juno?

In Roman mythology Juno was the Queen of the gods. She was married to the king, Jupiter, who wasn’t always well-behaved. Juno had to peer through the clouds to discover what he was up to; the spacecraft is called Juno because it will be looking beneath the clouds that cover the surface of the planet Jupiter.

Aboard the Juno craft are 3 models of Lego minifigures: Jupiter, Juno and Galileo, who discovered in 1610 that Jupiter had moons.

What is it looking for?

Jupiter is enormous; it’s two and a half times larger than all the other planets in our solar system combined. It’s made entirely of gases and is believed to have no solid surface. The planet rotates at an immense speed, completing one rotation every ten hours, and telescopes have shown us that it has a cloudy atmosphere with colourful spots and stripes. The largest of these, known as the Great Red Spot, is a storm that is several times the size of Earth and has been raging for more than 300 years.

This mission is the first time that humans will be able to glimpse what lies beneath Jupiter’s cloudy atmosphere. The main objective is to understand how the planet formed and evolved, which will give us more information about the formation of gas giants as well as the rest of the solar system. Juno will also measure the quantities of water and ammonia within the atmosphere, examine the magnetic field that surrounds the planet, observe any polar auroras and measure the gravity to see whether a solid core may exist after all.

For more information about the Juno mission you can watch this video from Nasa, and have a look at the Juno mission webpage.

Jump! into Etymology for Kids

Have you ever thought about languages, and how they develop over time?

Why do we say ‘tree’ when we look at a one of those green things outside our window, and where did the word ‘rose’ come from? (Can you tell that I am looking out of my window for inspiration?)

When we look at the links between the words that we use in English and those in a different country, we often find similarities. Information is the same in English, as in German and French, although the pronunciation is different.

The study of words is called etymology, and today Millie is going to explain a bit more about this, and tell us a bit about the word ‘JUMP’.

Adventure in Uganda

On my second day in Uganda, we went white water rafting on the Nile, near a town called Jinja. The rapids are just down river from Lake Victoria, which is where the Nile starts.

The rapids are caused by the force of the water as it crashes over rocks and around islands in the river. There used to be more rapids there, and the famous Bujugali Falls. However, a couple of years ago a dam was built across the river, which has made part of it more like a lake and has increased the water levels, wiping out lots of the rapids, including Bujugali. However, below the dam, the rapids are still just as scary! The rapids are a favourite for rafters and kayakers all over the world.
