Summary:

Head of Science Alastair Gittner, sets up the lesson by asking his students to consider how railway tracks are joined together, using their knowledge of the reactivity series. The classic thermit reaction between iron oxide and aluminium is too dangerous for the students to carry out, so instead they react zinc and copper oxide. Mixing small quantities of zinc powder and copper oxide together, then lighting the mixture, results in a bright exothermic reaction. Students can observe a chemical reaction taking place, as well as a new substance being made. Alastair, a science teacher at Stocksbridge High School, uses this experiment across the year groups. There are some safety precautions, such as using ceramic heat proof mats and ensuring students are wearing safety glasses. The reaction produces a lot of smoke, so the lab must be well ventilated.
