Precious metals

Why are some metals prized more for jewellery than others? Listen to presenter Bernie Hobbs explain the chemical reaction that affects the look and durability of metals. Using the periodic table and some dazzling computer graphics, Bernie demonstrates why 'oxygen-proof, low-reactivity, transition metals' such as gold keep ...

The Reactivity Series of metals

Students use this simulation to investigate the differences between potassium, sodium, iron and gold in reactivity with water in the construction of a bridge. Teachers have to explain how the reactivity series of metals can be determined by considering their reaction with oxygen, water and acid, and how to use the reactivity ...

Displacement Reactions

Students use this interactive to test five metals in an iron sulfate solution to see if a reaction will occur and understand that more reactive metals such as magnesium, aluminium and zinc will displace less reactive ones such as iron from their compounds.

Interactive Resource

Uses of some Elements

Students use this resource consisting of ten slides with diagrams, written explanation and voice-over to understand that the properties of some metals relate to how they are used. It also explains why alloys have been produced and how they are used. There is a two-question quiz and a summary slide.
