Under the Sea with the RRS Discovery
Last month the The RRS Discovery, the most advanced research ship was launched in Southampton.
At £75 million it is one of the most expensive research ships ever commissioned. It measures at just over 100 metres long, with seven main laboratories and a bridge like the Starship Enterprise! It has just begun expeditions around the British Isles, currently examining the UK’s continental shelf, a band of sea floor around 50m-100m deep.
“These shelves are really very important,” says Dr Sanders from the National Oceanography Centre in Southampton. “There is a lot going on in the shelf seas and we need to understand how they work so we can safeguard their future.”
How Did the Penguin Get its Name?
These days, we all know what a penguin looks like. Even if you haven’t seen a real, live penguin, I’m sure you have seen pictures, perhaps watched them in a film. It seems strange to think that people in Europe had no idea they existed for so many centuries! Perhaps you have wondered about that part of history.
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.
