Store Cupboard Science – Experiments at Home

While there are plenty of science kits in the shops, did you know that you can do loads of science with things that you already have in your store cupboard?  Science enthusiast Lisa White has put together a list of things that you need for a variety of basic science experiments.

You might need extra equipment but these are the basics. Having white vinegar, salt, bicarbonate of soda and washing up liquid in stock will be useful too!

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???

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.

A Short Story – Concrete

Cold, rough concrete beneath my burnt yellow hands, ash under my nails. I hold the butt of an already smoked cigarette in my mouth, looking hopeless. Not even the phrase, “Any spare change?” will get anybody to notice me, the old tramp of Brixton, sitting on the side of a busy main road. Every day I get unhelpful comments from young school kids, such as, “The local druggie! Ha, ha, ha…” These don’t make me feel better. It’s not my fault I’m unemployed, homeless and either drunk or high most of the time. Or is it?

People ask me how on earth I find all the money to buy over fifty cans of beer a week and a rather large variety of harmful grasses from drug-dealers. Sometimes I wonder too. I’ve only ever stolen something once. Twice then. OK! I’ve stolen eight times! Where else am I supposed to get money from (not including vulnerable children’s purses)? But, I’ve been thinking… Maybe, just maybe, it would be a slight possibility – just a slight one – that I could consider starting afresh. By ‘afresh’ I mean a new life in which I give up all my addictions, that are slowly rotting my bones, and make lasting friendships, that won’t break. Ever.
