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 the Mexican Day of the Dead (Día de los Muertos)?

On 1st and 2nd of November, Mexico celebrates its Day of the Dead (Día de los Muertos). This is a festival that begins on 28th October and ends on a public holiday on 2nd November. During this time, Mexicans believe that the deceased have permission from God to visit friends and relatives on earth, and once again enjoy the pleasures of life. It isn’t seen as a time of sadness and mourning but as a celebration of life.

Where Does the Tradition Come From?

The Aztecs believed that death was just a part of the circle of life and offered gifts to the goddess Mictecacihuatl (“Lady of the Dead”) for deceased children and adults. This tradition was incorporated into the Catholic celebration of All Saint’s Day and All Soul’s Day when the Spanish conquered the country. You might know All Saint’s Day by its other name – Halloween!

Water and Engineering – Water, Wonderful Life

Dr Lesley Beeton is a scientist, who studies what the DNA code tells us about human life and health. She has always loved science, and believes that science doesn’t just happen in laboratories. It happens all around us. Science keeps aeroplanes flying, electricity flowing, and the internet speedy.

Dr Beeton grew up in South Africa. Some of you may have traveled there for your holidays, to see the game reserves or Table Mountain. But even if you haven’t been there, we can all still learn something from the experiences of southern Africa.

Who Invented Denim Jeans?

If you’re anything like me, you’ll live in denim jeans when you’re not at school– they’re comfy, practical and come in loads of different styles, colours and designs. I’ve also got a denim jacket, which is perfect for throwing on over dresses when it’s cold outside. Even denim gilets come in and out of fashion on a pretty regular basis.

I think it’s pretty safe to say that denim has become something of a wardrobe staple over the years and in fact, I don’t really know what I’d do without it. But jeans haven’t always looked the way they do now and trends have changed a lot over the years.

The British Skeleton Team – Sliding to Victory

How would you like to slide down a very steep and winding track of ice on something very similar to a tea tray at around 140km per hour? Yes, no, maybe. Well, there are people out there who can and do want to. And what’s more, they’re really rather good at it.

Alongside Bobsleigh and Luge, the Skeleton is one of three sliding sports that take place on artificially refrigerated ice tracks. It’s a really white knuckle experience as each skeleton athlete pushes their sled one handed away from the start before lying down with their face first as they travel the track, using their shoulders, knees and toes for steering.
