The Effects of Acid Rain
Students explore the effect of chemical erosion on statues and monuments. They use chalk to see what happens when limestone is placed in liquids with different pH values. They also learn several engineering approaches to reduce the effects of acid rain.
After this activity, students should be able to:
- Give examples of common acids and bases.
- Describe acid rain and chemical erosion and how they affect the environment.
- List several things that engineers are doing to reduce acid rain and its effects.
