This lesson contains two activities to demonstrate two consequences of burning fossil fuels: air pollution and the greenhouse effect. In the first activity, students simulate the greenhouse effect with an enclosed beaker, water, Alka Seltzer, and a light source. In the second activity, a candle produces soot on a jar to simulate air pollution. Teachers should lead a wrap-up discussion to relate the two activities to the burning of fossil fuels.
