CANDLE POLLUTION



This experiment got us to see one component of air pollution. Keeping the security factor in mind I did not allow each child to do it , rather I demonstrated it for the class. I put the bottom of a glass above the flame of the candle so that the glass touches the top of the flame. Soot immediately developed on the glass. I explained to students why soot was created. Soot and other air pollutants are released when humans burn fossil fuels. It gave my students first-hand experience of some of the problems associated with using fossil fuels or energy.
