What is the Big Deal About Finding Richard III?

As skeleton found under a car park in Leicester has been identified as that of King Richard III, who ruled England from 1483 to 1485. Richard has been pictured as a tyrant king. There’s a story that Richard killed his own nephews, the legendary ‘princes in the tower’ in order to usurp the throne.

Nearly a century after Richard’s death, Shakespeare describes Richard as a ‘bottled spider’, a hunchback. Since Shakespeare’s time writers and artists through history have imagined Richard as a terrifying figure, whose physical disabilities are signs of his cruel inner nature.

Some historians argue that Shakespeare must have been writing propaganda to please his queen, Elizabeth I, whose grandfather Henry VII defeated Richard in battle. These historians argue that Richard’s ‘hunchback’ is an insult made up by Shakespeare, but until now, we haven’t been able to know what the truth is.

Let Toys Be Toys

Have you ever noticed that children’s toys are often labeled as “Boys” or “Girls” toys?
Very often, the girls’ toy area will be a sea of pink and glitter with a lot of beauty, cooking, fashion and baby doll items.  The boys’ area will have action figures, construction and science kids, plastic guns and dinosaurs.  Even board games can sometimes be separated in this way. Tina takes a closer look at why this is unfair for all kids, and what a group called Let Toys be Toys are doing about it.

Get Your Bake On!

 Have you been inspired by the Great British Bake Off?
We are BIG fans of 17 year old Martha, and love that she has shown Britain that kids can bake just as well (if not better!) than adults. After leaving the show, Martha said “I wanted to show that young people can do it and you don’t need hundreds of years of experience”.
A lot of you probably have already done a bit of baking with parents or grandparents, but moving on to baking independently can be a bit daunting. 
To help you get your bake on, we’ve some tips on getting started, and simple recipe ideas that will make you feel like you’ve baked a showstopper. So, move aside, mums and dads, this is all about baking for kids! 

 

 

On Your Marks, Get Set… BAKE!

Before you start to bake, get all your ingredients out and put them on the worktop. This prevents you getting halfway through the recipe and then noticing that you’ve run out of something really vital, like eggs!

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.

Who Invented the First Electric Battery?

When we talk about electric batteries, we often talk about voltage. But did you know that this word is named after the person who invented the first electric battery? First, let’s take a look at what a volt is, and then we’ll find out more about the guy who gave the ‘volt’ its name.

 What is a Volt? 

A volt is defined as a unit of electric potential and electromotive force, and voltage refers to the number of those units. That sounds a lot more complicated than it is! If you think of the water in a tap being like the electricity running through a wire, the voltage means the amount of pressure. This video is quite long but explains it very well. 

 

 

 

Why are Volts Called Volts?

Alessandro Volta

The term actually comes from a name. It was coined in honour of Italian physicist Alessandro Volta, who is recognised as the inventor of the first electric battery. During the 1790s, Volta worked on the theories of electricity of the day.

Volta disagreed with the theory proposed by fellow Italian scientist Galvani that electricity was generated by animal tissue. Instead of experimenting on frogs or other animals, Volta did experiment after experiment with metals.

His persistence paid off, and in 1800, he invented the world’s first battery, known as the ‘voltaic pile’.

 

The Voltaic Pile

Volta's Voltaic Pile, the first electric batteryThis voltaic pile was simple but ingenious. It consisted of a pile of zinc and silver discs. But alternating between them was a piece of cardboard, or a piece of cloth, that had been soaked in saltwater.

There was a wire that connected the zinc disc on the bottom to the silver disc on the top, and this wire was capable of producing sparks.

What else Did Volta Invent?

The invention of the first electric battery brought Volta the most fame and recognition, but he also made other discoveries. He invented the electrophorus, a device that could transfer an electrical charge to other objects, as well as an electrical condensor, and the voltaic cell.

He is also known for having discovered and isolated methane gas. After his death, the volt and voltage were named in his memory.

 What about Galvani?

Luigi Galvani

Yet there is one more twist to the tale. Volta’s longstanding colleague Galvani of the animal electricity theory also left his name in our language. When we say ‘galvanise’ or ‘galvanism’, that is where it comes from.

Despite their differing theories, there was no rivalry between the two scientists. They were both more concerned with the pursuit of knowledge than with whose theory would prove to be right, and it was Volta who first coined the word ‘galvanismo’ in Italian.
