Instructional Ideas

• Relate the combustion observations to combustion engines

Classroom Considerations

• Use caution with hydrogen peroxide and hydrochloric acid as both cause chemical burns and skin irritation
• Do not look at burning magnesium as it emits harmful UV radiation that will damage your retina
• Follow all safety rules with open flames

Pros

• Includes combustion of wood, candle wax, sulfur, iron, hydrogen, and magnesium
• Provides clear instructions and a diagram of how to set up the decomposition reaction

Cons

• None
