A Catalyst article about practical chemistry experiments and the risks involved. The article helps in identifying, assessing and controlling the risks involved, it also includes a guide to the warning signs, labels and symbols used in laboratories.

This article is from Catalyst: GCSE Science Review 2004,...

This activity allows pupils to learn how to analyse samples on Mars. Students are given the opportunity to use targeted information in areas of astrobiology and geology, to work out what their rovers have found on Mars surface and to think like a geologist as they investigate stratigraphy (layers or rocks) using...

This collection includes the topics that were developed by international teams of teachers participating in Science Across the World between 1991 and 2010. The project was run by the Association for Science Education (ASE). A special feature of the topics is that they are available in several languages. Every topic...

This collection includes the topics that were developed for secondary students by international teams of teachers as part of the Science Across the World project. The project was run by the Association for Science Education (ASE). Every topic leads towards an exchange of findings and ideas between groups of...

The Centre for Industry Education Collaboration (CIEC) produces classroom resources and teacher guidance to help highlight the links between classroom science and science-based industry. Resources in this collection contain information about the chemical and plastics industries as well as practical guidance about...

This Catalyst article outlines volunteering opportunities for young scientists, engineers and medical students who put their studies to good use, working with local people around the world to bring the benefits of technology to communities who otherwise would go without some of the basic needs of life.

This Catalyst article describes how biophysics is helping in the search for novel antibiotics. Bacteria produce an array of proteins to kill off their competitors. These proteins, called bacteriocins, are very efficient at penetrating the defensive outer layers of bacteria cells by moving through specific membrane...

As transistors become smaller, the doping of semi-conductors becomes a significant challenge. This Catalyst article looks at how Scanning Tunnelling Microscopes can be used to manipulate individual atoms, to create electronic devices of unprecedented accuracy. The technique could also be used to fabricate quantum...

These materials look at three possible projects that relate to cleaning products and tackling microbes that spread disease: * Communications project - students act as health promotion specialists trying to persuade people about the need to wash hands after using the toilet. * Practical project - students...

Students research, and then try out, ways of detecting analgesic compounds in mixtures:

• Chemical tests for particular organic functional groups.

• Paper and/or thin-layer chromatography to separate and identify analgesic...

Produced by Solar Spark, this is a simple practical activity that can be used to show how a solar photovoltaic cell works. During a 45-60 minute session, students make solar cells out of cheap and readily accessible materials. The mechanism behind the solar cell is similar to that used in a dye-sensitised solar...
