Why does acid rain decrease the pH of some lakes and not others? Explore the role of different bottom materials in keeping the pH of lakes constant. Create mini-lakes with different bottom materials and limestone. Add acid rain to your mini-lakes and test the pH. Determine which lake bottom material is a buffer that keeps the pH of the mini-lake water relatively constant. This complete experiment setup contains all materials and does not require lab equipment.
