Learning Guides. Practical Chemistry. Practical Chemistry. This website is for teachers of chemistry in schools and colleges.
It is a collection of experiments that demonstrate a wide range of chemical concepts and processes. Some of the experiments can be used as starting-points for investigations or for enhancement activities. Many have links to carefully selected further reading and all include information and guidance for technicians. Chemistry is a practical science. Practical activities are not just motivational and fun: they also enable students to apply and extend their knowledge and understanding of chemistry in novel investigative situations, which can aid learning and memory and stimulate interest.
