If you are tired of the same titration experiment year after year this may be the answer. Students measure the pH of rain water and then investigate how filtration through various soil types affects the pH to answer the question of whether the pH changes as it passes through soil

Hands-On Environmental Chemistry

Excellent activity for more advanced high school and first-year applied/environmental chemistry students. We have all heard about acid rain, but how does the environment deal with acidic pH?... See More

Excellent activity for more advanced high school and first-year applied/environmental chemistry students. We have all heard about acid rain, but how does the environment deal with acidic pH? Students are challenged to identify the ability of soil to buffer soil pH, and in the process, learn about designing an experimental procedure to test various soil types. The ability of soil to buffer pH has a great effect on the ability of various plants to grow in the soil. Once students have completed their experiments, they are challenged to discuss the results, impacts, conclusions, and questions for further research. Great way to bring some realism into the classroom. Standards correlations were not provided.
