Acid Rain and Buffers
Learn how certain types of lake bottoms can act as buffers.
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.
