Health and safety regulations frighten many science teachers away from exciting practical experiments. But there is no need to be afraid: support exists to ensure chemistry demonstrations are practical and safe.Wendy Butler, a teacher at St James&39; Catholic High School in Barnet, performs four experiments in a chemistry lesson on reduction-oxidation reactions with her Year 11 class. Her experiments are safe, but not entirely successful. So Wendy has a training session with CLEAPSS to ensure the job is done right. She achieves great results.Key points: * To engage students in chemistry, it?s important for demonstrations to be visually appealing * Spectacular experiments can often be performed safely * There?s lots of support available if your experiments aren?t working
