In 1986, a deadly cloud of carbon dioxide gas was released from Lake Nyos in Cameroon, West Africa, killing over 1,700 people and 6,000 head of livestock. What caused this natural disaster? Students find out when they re-create the conditions at Lake Nyos. Using only simple materials such as a candle, a plastic cup, vinegar, and baking soda, students can observe first hand the nature of carbon dioxide gas and its role in this event. You will receive all necessary materials including one plastic volcano model for a class demonstration, a teacher’s guide, and student copymasters.
