Classroom Ideas

The clip can be used to cover combustion as a reaction and to discuss the reactants and products. Ask students to describe a molecule of carbon dioxide to their partners. As a practical exercise, a candle could be burned and the products drawn over blue cobalt chloride paper and through limewater to show the presence of water and carbon dioxide.
