This 9 slide presentation introduces the idea of metals burning using stunning images and a You Tube video of burning Iron wool with a long exposure (complete with safety information). It continues by discussing the three factors that determine the combustibility of a metal in air.

The second part of the lesson is the classic burning magnesium in a crucible complete with diagram, results table, safety instructions and a step-by-step visual guide provided by a You Tube video.
The quantitative practical shows not only how reactive metals can burn in air but also re-visits the Year 7 Conservation of Mass concept by weighing the magnesium before and the magnesium after.

The presentation concludes with a page reference to reinforce the learning and there is also a word-search included as a starter.
