This lecture from the Lindau Nobel Laureate Meetings outlines the development of the field of quantum mechanics. The lecture describes the work of Planck, Einstein and Bohr and includes the idea of wave-particle duality, the photoelectric effect to Bohr's model of atomic structure. The lecture's emphasis is on the...

In this practical investigation, students will perform a combustion reaction using a mixture of alcohol and air in a plastic water...

This simulation explores the factors which determine the concentration of a solution. It illustrates the relationships between moles, litres and molarity by adjusting the amount of solute and solution volume.

The moles of solute and the volume of solution (water) can be changed using sliders to make...

The Association of the British Pharmaceutical Industry represents the manufacturers of most of the medicines and vaccines supplied to the National Health Service, in the UK. As part of their programme to encourage the study of science in schools, in 1995, the ABPI produced a book for post-16 students, on the...

This simulation allows students to explore molecule shapes by building molecules in 3D and seeing how the molecule's shape changes as atoms are added.

It can be used to demonstrate that:

*The molecule shape is due to repulsions between atoms.

*The bonds are not fixed in place, but can rotate...

This Catalyst article takes a look at Mount Etna on the Italian island of Sicily, the biggest and tallest active volcano in Europe and one of the most active in the world. The article explores the geology of the volcano, its history and the local habitat surrounding it including how the volcanic conditions create...

The mystery revolves round a detective story which the students gradually solve. A jeweller has been murdered: the suspects are his metal suppliers but the motive and the culprit are initially unknown.

In 2012, the Royal Institution Christmas Lectures explored the chemistry of the modern world. Following this theme, the Royal Institution asked colleagues, celebrities and scientists to choose their favourite element and explain why they liked it so much. One of these short films was published every day in December...

This Unilever Laboratory Experiment, published in 1967, describes a procedure based on the use of 1 -fluoro 2,4 dinitrophenylation (FDNB) as developed by Sanger during his studies on the structure of the protein hormone insulin. In the experiment, two dipeptides are used which contain the same two amino acids but...

From the Wellcome Trust, the 'Big Picture' looks at issues in science.

Dealing with things smaller than 100 nanometres (for comparison, a human hair is 80,000 nm wide), nanotechnologies are fast becoming the 'next big...

A Catalyst article providing examples of some drugs derived from natural substances. Many drugs which are commonly used today are similar to naturally occurring compounds which have been used for centuries to treat illnesses. Chemists have identified and purified these substances. By determining their molecular...
