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.

SCIENCE NEWS – What is Dengue Fever and Could Genetically-Modified Mosquitoes Prevent It?
Dengue (pronounced den-gee) fever affects between 50-100 million people each year, with around 25,000 people dying from the disease. It’s most common in south America and parts of Africa, and is also known as breakbone fever because it causes such intense pain in the bones. Dengue fever is a virus that’s spread by mosquitoes, and there is no vaccine or effective drug treatment to prevent or cure it.
Get Cracking With Computer Coding for Kids
Kids computing – there’s a lot of talk going on about it right now. What do you learn about computing in your school? Are they teaching you how to make cool video games? How to come up with a story that makes sense, how to make sure that it’s engaging, that there are challenges at each level, and that there’s a reward at the end? How to build that?
How to make the bird you toss flop realistically into a pile of whatever you choose – making sure that gravity works the way you would expect it to (or not). How to craft the graphics you need to tell your story? How to publish that to your own smartphone and to share it (or sell it!) to friends and strangers?
Hmmm, I didn’t think so. “ I’d rather just do some Power Point and Word exercises, “ said no kid, ever.
