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.
Great Women You Should Know – Mary Wollstonecraft
Mary Wollstonecraft is known as one of the earliest feminist thinkers and writers to become famous and influential throughout Europe. This reputation comes from the publication of her book “Vindication on the Rights of Women” in 1790. At the time it was written, women in Britain didn’t go to school, weren’t allowed to vote or do the same work as men. But who was she, and where did she come from?
What is Geocaching?
What is Geocaching? It’s like a real-life treasure hunt and is a great way to make a walk in the woods just a bit more interesting!
Julianne Robertson explains what it is and how to do it.
What is it?
Players use a handheld GPS device or a smartphone to look for a set of co-ordinates near to wherever they are and find the geocache (or treasure!) hidden at that location. These are usually a small container of some kind with a logbook and ‘treasure’ inside – this can be anything, like a little toy, some stickers, a badge, a pretty stone – basically anything small enough to fit inside and be worth finding!
Sounds good! How do I get started?
Go to the website www.geocaching.com and register – it’s free to sign up. Then you put in your postcode and you should see a list of all the geocaches near to where you live. Choose one and you’ll get the co-ordinates you need to put into the GPS, as well as a description of the area and clues about how to find the cache.
Are geocaches always hidden in the woods?
No – there are geocaches all over the world and they are usually put in places which are important to the person hiding them. Some are hidden in forest areas, others are in local parks, or city streets – even underwater! There are also different sizes of geocache and a range of difficulty – you should probably start with one that’s easy, at least to begin with!
What do I do when I find one – can I keep the treasure?!
Yes, but you should replace anything you keep with something of equal or greater value. You should also write about your find in the logbook and when you get home log your experience on the website too, so that others know the cache is still active.
Can I hide my own cache for others to find?
Yes, once you’ve found a few caches you’ll know what makes a good geocache and hiding place, and you might want to create your own! There are lots of guidelines on the website about how to do it.
Now you know about geocaching – go and try it! It’s a great activity to do with your family or a group of friends. Once you’ve found one, you’ll want to find more!

What is Falcon 9?
There has been a lot of excitement about Falcon 9, but what it it, and why is it so exciting? Our Science Editor, Samantha Gouldson, explains.
How to Be an Inventor
Have you ever thought ‘There MUST be an easier way to do this’? If you have, you are not alone. People around the world invent and re-invent products all the time. Some of them are professional, and inventing is part of their job. Others are just normal people who had a bright idea.
There are many clubs and societies which you can join and learn to invent or develop your curiosity and talent for science and invention. All inventors start somewhere, and most of them start when they are very young. Young people have the best imaginations so if there is something you think is a good idea and you want to try and create, why not join up with other young creative people and work together.
