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 Point in Learning Maths?
Have you ever sat in a Maths class wondering when you will ever need 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 maths?
Let’s start with Maths. It is a fact of life that while some people are good at Maths, for others it is a daily trial. It is, however, along with English and the sciences the subject considered to be the most important. Why? Of course, we all know that it is important to be able to count, and do simple sums, but when, in real life, do we actually use it?

Adventure in Uganda
On my second day in Uganda, we went white water rafting on the Nile, near a town called Jinja. The rapids are just
down river from Lake Victoria, which is where the Nile starts.
The rapids are caused by the force of the water as it crashes over rocks and around islands in the river. There used to be more rapids there, and the famous Bujugali Falls. However, a couple of years ago a dam was built across the river, which has made part of it more like a lake and has increased the water levels, wiping out lots of the rapids, including Bujugali. However, below the dam, the rapids are still just as scary! The rapids are a favourite for rafters and kayakers all over the world.
