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.

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.
Last Minute Homemade Halloween Costumes
What’s your favourite holiday? Christmas? Easter? Or is it Halloween? The day when we let our imaginations run wild and, instead of feeling that we have to prettify, we are encouraged to look as disgusting as possible.
I love Halloween, I love getting dressed up and playing games. I love bobbing for apples and grossing everyone out. Once upon a time we just threw on a sheet with eye holes cut out, those days are long gone. Now we consider our costume choices carefully. We co-ordinate, we plan and we get excited. You don’t need to spend a fortune on fancy costumes though, nor do you need to be an expert face painter. Here are a few ideas to get you started.
