MYP 7.4.7: Pollution from fossil fuels, limited to SO2 (acid rain) and CO2 (greenhouse effect)

Objectives

 

 

Introduction:

Revision of topic 7.3.2

Small samples of sulphur could be burned in gas jars and then shaken with water. The resultant solution could be tested using universal indicator.

There are candles that have been impregnated with sulphur that could be burned in a gas jar. Strips of magnesium could represent architecture that becomes corroded.

Student Activity

Students could look at the reaction between hydrochloric acid and marble chips. It is possible to measure the rate of erosion (chemical reaction) by leaving the chips in acid for a measured time and drying and weighing.

The students could design an experiment to investigate this effect.
