Who On Earth Invented … The Pedal Bin?!

Continuing our series on enterprising inventors of everyday things we take for granted, Sally Anne asks …

Who on Earth invented…the Pedal Bin?!

You’re carrying something to the bin, your hands are full and you don’t want to spill it. Thank goodness for the pedal bin! Read on to find out about the inventor who tried to make life easier.

Ergonomics is the science of making equipment which fits and works with the human body. This basically means making things work as easily and as conveniently as possible. Dr Lillian Gilbreth was a keen inventor who believed in finding the easiest way of getting things done. As such, she invented a range of gadgets to make jobs easier, including the pedal bin in the 1920s. Now we have to admit, pedal bins aren’t very exciting, but Lillian’s life definitely was.

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.

Is Black Really White?

Science will tell you that black is not a colour, rather it is the absence of colour or the fact that there is no colour there. I expect that makes you think of white, rather than black!

And that’s the interesting thing about the word black: it was nearly white. And in fact in several other languages, the same root did develop to mean white.

Carnivals Around the World

You might have heard of the carnival in Rio, but did you know that there are carnivals around the world – from Germany to Greece, USA to Italy?

Millie Slavidou explains where Carnival comes from on her blog

Long before the advent of Christianity, people held celebrations at this time of year. In Germany, they once looked forward to sending Hel, the goddess of the underworld, back down to her abode so they could herald the coming of the spring. In Greece, it was a time to worship the god Dionysus. With the arrival of Christianity, the celebrations continued, but changed in nature, gradually becoming more and more linked to the new religion. The Carnival is held in the period before the start of Lent, and Lent is the time when good Christians were supposed to fast, to abstain from meat

In the UK, we don’t celebrate Carnival, but we do prepare for Lent – that is what Pancake Day is all about, after all. Traditionally, pancakes were made to use up the eggs, fat, and butter, that were not to be eaten during Lent!

Take a trip around the world with us, to find out how other countries celebrate Carnival!
