Create a micro environment in an aquarium where sulfur and nitrogen oxides are generated. A simulated “rainstorm” carries the airborne pollutants to the “pond” and “countryside” below. The effects are immediate, obvious and unforgettable. Bring exciting visual imagery to otherwise vague, intangible concepts. Teacher Demonstration Notes included.
Concepts: Environmental chemistry, acid–base indicators, pH, gases, neutralization reactions. Time Required: 30 minutes Materials Provided: Universal indicator, marble chips, sulfur, nitric acid, sodium hydroxide solution, hydrochloric acid solution. Note: A 15- to 20-gallon aquarium, sand or fine gravel, large disposable roasting pan and aluminum foil are required but not provided; fume hood is strongly recommended.
