Electrons in atoms and molecules

This is an interactive resource about how the interactions of electrons with matter are central to many technologies from transistors, diodes, and smoke detectors to sophisticated imaging, lasers, and quantum computing. Students explore electron cloud models of atoms involved in covalent bonding and ionisation and relate ...


Laptop wrap: Modelling atoms

A page with a focus on exploring different models of the atom. Includes tasks to present models of the atom.


Build an atom

This is an interactive resource that allows students to build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Students can view the atoms using the electron shell model or cloud model. A small set of games give students the opportunity to review their understanding of how ...


Atomic structure

This is an interactive resource about ion formation, isotopes, and electron orbital placement. Students construct models of atoms with properties of particular mass and charge; create models of atoms with different stabilities by adding or subtracting neutrons, protons, and electrons to a model atom; and determine that ...


VisChem topic 7: intermolecular forces

This web page contains animations demonstrating situations in which dispersion forces, ion-dipole forces and hydrogen bonding occur. Several animations show hydrated ions, and the effect of hydration on dissolving and reaction rates is discussed in explanatory text. A document containing lesson plans and student worksheets ...


VisChem topic 6: molecular structure, shape and polarity

This web page contains ten animations of molecules and compound ions as well as nine QTVR objects showing organic molecules. The animations rotate the molecules to show their structure fully. The QTVR objects can be manipulated by the user so that, as well as being rotated, different ways of modelling the molecules can be seen.


VisChem topic 8: chemical properties of water and aqueous solutions

This web page contains video clips, animations and student worksheets that investigate the chemical properties of water and aqueous solutions. The major topics cover the structure and bonding of water, acids and bases, dissolving, ionic solutions, precipitation and complexation.


Oresome world

This interactive resource takes students on a journey of discovery in the energy and mining world. Oresome world contains five games or modules: Coal, Energy, Gas, Low emissions and Mining, and within each of these there are several facilities to explore, such as the Underground mining site, Hydroelectric power station, ...


VisChem topic 9: physical properties of water

This web page contains a video, animations and a student worksheet exploring the influence of structure and bonding on the physical properties of water. Two animations showing structure and bonding in oxygen are provided for comparison.
