What is a Stick Bomb?

11-year-old Andre Jefferson explained stick bombs as being, ‘a kinetic chain reaction that is weaved together with jumbo popsicle sticks, that creates tension, and when you take one of the sticks out, it releases potential energy and makes it pop up about this high’.

Green and Growing: The Life of a Seed

As you know, there is a vast number of different kinds of plants growing all over the world, from snowy slopes to Amazon rain forests to dusty deserts: plant life is everywhere. So how does it all work? Lets start with seeds.

 

 The Life of  a Seed

Picture a seed – I am sure you have all seen them. It will have a hard outer shell to protect it. When it has found the right conditions of warmth and moisture, this shell will crack or split as a root pushes its way out to take hold in the soil. Then the plant will start to grow and a shoot will make its way upwards, with the root growing down, to draw moisture from the ground and provide some balance for the plant, keeping it firm in its place.

Just like you and me, plants need food to grow. Their food is very different from ours, of course! Here’s what they do: the leaves draw water up from the roots, through the stem, and they also soak up sunlight and air. These three things combine to make food in the leaves, where it is stored. Now think of an onion. It is formed to store the food for the plant.

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!

Women You Should Know… Agnes de Mille
