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.

Rock, Paper, Scissors… Robot???

The game rock-paper-scissors is well known around the world. We’ve all used it as a choosing method, or simply as a game! The easiest version is played between two people. Both players choose one of the three shapes for one of their hands, and reveal their choice at the same time, hoping their choice beats their opponent.

It’s nearly impossible to gain an advantage over your opponent, unless you wait long enough to identify their choice before you make yours, but the chances are that they will realise your cunning plan and call you a cheater!

This game is not simply a choosing game. There are mathematicians dedicated to constructing algorithms for the best strategy to win, and scientists devoted to creating unbeatable robots! In fact, researchers at the University of Tokyo have created a rock paper scissors robot that wins at rock-paper-scissors 100% of the time.

What is The Point of Learning English?

Have you ever sat in a Maths class wondering why you will ever need to be able to do long division without a calculator? Or silently cursed your Geography teacher while learning about the formation of oxbow lakes? And History? That’s all in the past and irrelevant, isn’t it?

In this series of articles, we will look at some of the subjects we learn at school, and try and answer the question: What’s the point in learning this?

Last time we looked at uses of Maths, both in day-to-day life, and for your future career. Today we will focus on learning English. Once we have learned how to read, write and spell, what is the point? Will we ever need to quote Shakespearian sonnets? And who, other than writers, needs to be able to write stories and poems?

What Causes Motion Sickness?

Motion sickness is also known as travel sickness, sea sickness or air sickness. It can happen in a number of situations, not all of which involve movement, and is a very unpleasant sensation. As part of our Have You Ever Wondered series, our Science Editor Sam finds out what causes motion sickness, and if there is anything you can do to prevent it.

What does ‘social hierarchy in schools’ mean? It means the status of each person in the school.

You know how some kids are the ‘cool kids’ and some are the ‘nerds’ or the ‘geeks’. The hierarchy means the levels of ‘cool’. Our contributor Madeleine decided it was time to shake things up a bit.
