Have you ever wondered…why leaves change colour in autumn?

Autumn is a season of change; the weather gets colder, there’s less daylight and leaves change colour and fall from plants. But why does this happen?

Why Do Plants Have Leaves?

Leaves contain a chemical called chlorophyll (pronounced KLO-ro-fil), which as well as giving them their lovely green colour also helps create food for the plant. The leaves act like tiny solar panels, and use the sun’s energy to convert water (from the ground) and a gas called carbon dioxide (from the air) into sugar and oxygen. This process is called photosynthesis (pronounced foto-SIN-theh-sis), and the sugar is what the plant lives on.

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!

Tarragon: the Snake in your Kitchen

Even if you are not a budding chef, you might have heard of this herb. It can be used in all sorts of ways in cooking, especially with chicken, eggs and fish. And if you are fortunate enough to have tried French cuisine, you may have had it in Bearnaise sauce.

But where did the name come from? You might think it looks very English, but in fact, this word has had quite a journey to reach us in the form it is today in English.

“Tarragon” first appeared in this form in the 1530s, but it came from an earlier English form; taragon. This was formed from the Middle French term targon, which came from Medieval Latin tragonia. But the story doesn’t end here. There is an intriguing twist in the tale.

What is a Malapropism?

You may not have had the term ‘malapropism’, but I am sure you know what a malapropism is when you hear it! It is when you get one word mixed up for another and as a result change the meaning of a sentence completely.

For example you might mean to say to your friend, “I’m bored, let’s go watch telly”, but what you actually say is, “I’m bored, let’s go eat telly”. 🙂

What is a malapropism, and why does it have such a funny name?

Stories From The Stables – Sam

This is first of a series of Stories From The Stables, by Carolyn Ward.

I fell off, honest

Learning to ride is a fabulous hobby. It can be pricey, but you can borrow a hat and crop from most stables, and start off in trousers and strong shoes. It is great exercise, very exciting, and teaches respect for animals, balance, and correct posture.

When I was very young I rode at Stourton Stables, a children’s riding school where the ponies were mostly grumpy and had to be separated in the fields for fear of kicking each other to pieces.

Oh, happy riding lesson days. Hours spent in icy pouring rain, in snow, in fog, and even more rarely; in lovely sunshine. The best riding times of year for me were spring and autumn, before and after the major insect season.
