It’s genetic, isn’t it?

Genetics is the study of how genes are inherited in a population. A scientist interested in genetics is a geneticist. If something is genetic, that means it is passed to you by your Mum and Dad. You inherit genes from your parents.
Genes control most aspects of human life, from eye colour to how fast you can run. There are some fun ways to demonstrate genetics in your own family.

Take tongue rolling. The ability to roll your tongue is what we call a dominant trait. If you have the gene for tongue rolling you will be able to roll your tongue.

Rock, Paper, Scissors… Robot???

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.

Drip Drip Drip

Can you imagine not being able to turn on a water tap? Can you imagine not even having a water tap?
Today’s challenge is to notice when you do something that we all take for granted – turning that tap and letting the water flow.
Washing your hands, cleaning your teeth, taking a shower. You are thirsty, so take a big gulp of water straight from that tap after playing outside in the sun.
Every time you turn on a tap of water, think about how easy it was and what you would do without running water.

Fairtrade Bananas

You might have seen the logo – stuck to bananas, in the corner of chocolate bars or perhaps on the label of jars of coffee or boxes of tea stacked on the supermarket shelves. But have you ever wondered exactly what the table ‘Fairtrade banana’ means and who it helps? Clara Wiggins explains all.

 

Until recently I lived in St Lucia, a small island in the Eastern Caribbean. A beautiful piece of paradise, St Lucia is one of the many islands in that part of the world that has relied for years on a combination of income from tourism and the sales of its fruit and vegetables – specifically bananas – to gives its people a reasonable standing of living. Life on these small islands is tough, they are very vulnerable to things like hurricanes and outside events that stop tourists coming on holiday. But as long as people bought their produce, the people of St Lucia were able to get by and children were able to go to school and get a good education.

 

 

 

Unfortunately, things changed. A few years ago, a change in trade laws meant that the UK stopped buying so many of their bananas from St Lucia and other islands in that part of the Caribbean – known as the Windward Islands – and started buying more of them from Latin America and West Africa.

Supermarkets in this country also became increasingly competitive and wanted to offer their customers cheaper  produce to buy. As bananas have always traditionally been one of the most popular items for supermarket shoppers, these were offered at lower and lower prices – meaning the farmers who were growing them were getting paid less and all the people who relied on their income were finding it harder and harder to survive.

This is where Fairtrade stepped in. As an organisation, the Fairtrade Foundation ensures that farmers and other producers are offered a fair and stable price for their goods – and at the same time help improve the working and living conditions of the workers and their families.

After the changes to the trading laws meant fewer bananas were bought from St Lucia and the other islands, the number of banana farmers dropped from 27,000 to around 4,000 – which led to high unemployment, youth unrest and an increase in poverty. But the first consignment of Fairtrade bananas was shipped to the UK in 2000 and since then volumes have grown until today more than 90% of the farmers in the Windwards belong to a Fairtrade group. The knowledge that they will get a good price for their fruit has changed the lives of the farmers. Now they can afford things that we take for granted, like health care and decent education for their children. It also means they can use the money to invest in expanding into other areas and hopefully build back up the number of people employed in this work.

Of course Fairtrade isn’t just about bananas from the Caribbean – you can now buy a huge range of goods including chocolate, flowers, rice, sugar, even beauty products all stamped with the Fairtrade logo from countries across the globe. And every time you do so, you know you are helping someone like the banana farmers to build a better future for themselves and their families.

But as well as buying Fairtrade goods, another way to get involved is to turn your own school into a Fairtrade school.

A Fairtrade school is one that uses Fairtrade products as far as possible, commits itself to learning about how global trade works and why Fairtrade is important and takes action for Fairtrade in the school and wider community. Already, there are nearly 500 schools with Fairtrade status, with many more going through the process to gain certification.

As well as all the obvious reasons for doing it – ie helping the world become a fairer place and helping to reduce poverty – being part of a campaign to get your own school to become a Fairtrade School has many benefits closer to home. It could help you to develop your own skills, have a positive influence on your local school community and – above all – it can be great fun.
