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...

A Year Ten module from the Salters’ double award science course. The module begins with a survey of minerals world wide and their constituent elements. This provides opportunities for practice with symbols, formulae and equations. A practical simulation of geological...

This resource uses the context of the British Challenge for the America's Cup to explore composite and nano materials.  The video uses the challenge to build the highest performing racing yacht as an introduction to composite materials and how they are designed to improve their properties for a specific use.  This...

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...
