Aluminium

A Catalyst article about aluminium, a shiny silvery metal, which is extracted from its ore by electrolysis. Further addition of other metallic elements results in an alloy, which can be cast into various shapes using moulds. The article looks at the processes of extraction, casting, patterns, moulds and finishing...

An Eggsperiment on Teeth

This Catalyst article describes an experiment with fluoride toothpaste on eggshells (as a substitute for teeth). Both teeth and eggs contain calcium compounds which can be attacked by acid. When an egg is put in vinegar the shell is weakened by the acid making it soft and more fragile. When teeth are exposed to...

Ancient Air in an Antarctic Ice Core

A Catalyst article about ice cores from Antarctica which contain air bubbles which record the changing atmosphere. The Antarctic ice sheet is over 3 kilometres thick; ice cores enable scientists to sample each year of snow fall in sequence. This evidence is vital in understanding how the climate is changing. The...

Animal Testing

A Catalyst article looking at how research using animals causes heated debate. New drugs must be safety tested on two species of animals, the article looks at how many experiments use animals and how they are regulated, scientific procedures and genetically modified animals.

This article is from Catalyst:...
