• Methane
• Nitrous oxide

Natural Reactions

Carbon Dioxide

• Trends in carbon dioxide levels
• Activities & Demonstrations
  • dry ice sublimation
    • "shiver dollar"
    • exthinguish candle
    • pH change
    • carbon dioxide is denser than air
    • floating soap bubbles
  • carbon dioxide production
    • yeast and sugar in flask - respiration
    • vinegar and baking soda -extinguish candle
  • combustion
    • observe a candle burn - where does the mass go?
    • combustion time under different size flasks
  • carbon dioxide release from solution
    • release pressure from cold and warm soda bottles
