Year 8 create Magnesium Oxide

On Wednesday 14 November 2018, Year 8 SISKY students performed an oxidation reaction with magnesium to create magnesium oxide. Magnesium burns in heat and produces a bright flame. Students calculated the mass of the magnesium before the reaction, and after, to show change in mass as oxygen combines with magnesium in the oxidation reaction." data-share-imageurl="">

On Wednesday 14 November 2018, Year 8 SISKY students performed an oxidation reaction with magnesium to create magnesium oxide. Magnesium burns in heat and produces a bright flame. Students calculated the mass of the magnesium before the reaction, and after, to show change in mass as oxygen combines with magnesium in the oxidation reaction. The lid of the crucible must be lifted periodically to allow oxygen to enter to continue the combustion. The lid must be quickly returned to prevent fumes from escaping and to protect eyes from the bright flame of the magnesium. The students were enthralled by the glow of the oxidising magnesium without direct contact with the burner, and their delighted faces show their enthusiasm for laboratory practicals involving combustion.
