Global Water Experiment

The Global Experiment consists of four experiments. It is expected that most teachers will work with their classes to carry out the four activities, which have explicit instructions and background materials. These will be helpful for teachers who do not have science backgrounds.

Extracting DNA from Kiwis

DNA is a special chemical found in the cells of every living thing. It’s special because it carries the instructions for making each living thing. DNA is a very long molecule but it’s so thin that you can’t normally see it. In this experiment we will show you how to extract DNA from a kiwi fruit.

Exploring acids & bases at home

You might be surprised, but loads of the household chemicals we use every day are either acids or bases. We can find out if something is an acid or a base by using an indicator. You might have come across some indicators in school e.g. litmus, but you can easily make your own indicator at home using red cabbage! We can measure how acidic or basic a substance is by using the pH scale. It goes from 0 to 14 (0 is very acidic, 14 very basic and 7 is neutral).

Smartie Chromatography

We all love sweets, especially colourful ones like Smarties, M&Ms and Skittles. But how do they get all those colours? Well, the manufacturers mix different food colourings to make the wide variety of colours we see in each pack. We can use a process called chromatography to separate the different dyes and explore the colours in sweets. Chemists use chromatography to separate difference chemicals and to investigate what is in different mixtures.

Supercool Water

Water is the only substance on our planet that exists naturally in all three states of matter. In other words, it is found as a solid, liquid and gas. Water freezes at 0oC but sometimes we can cheat and supercool it! Supercooling means bringing water below its freezing point (0oC) without it turning to solid.

Fruity Electricity

You can get a bulb or LED to light by connecting it to a battery. The first battery was made by Alessandro Volta in 1800. He created a voltage between a piece of copper and a piece of zinc placed in a solution of salt water. The voltage can be measured using a voltmeter. The voltage generated can be used to light a small torch bulb or LED. The simplest form of electrical cell or battery uses copper and zinc in a solution of dilute acid. - Find out more here!

STEM: What’s it all about?

In today’s world we face a number of challenges, from climate change to sustainable food sources, from the treatment of diseases, to online security and more. With a global population that is increasing all the time, the world needs more problem solvers skilled in science, technology, engineering and maths (STEM) to help find solutions. STEM skills are crucial to the modern world and are an important part of the Irish economy.
