In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain. Antacid tablets made with calcium carbonate are used to represent marble (also made from calcium carbonate), and vinegar is used to represent acid rain. Learners observe the effect of adding water to one tablet and vinegar to another. The tablets can be made into slightly more realistic models by drawing on them with a pencil, or rubber stamping a design with waterproof ink. This activity could be used in connection with lessons on pollution and acid rain, or lessons on art and architecture.
