They then apply principles of acid-base chemistry to deal with some of our water pollution problems. Students are introduced to the concepts of probability, risk, risk comparison, and decision making.
Experimentation introduces the concepts of qualitative and quantitative analysis.
A simulated animal toxicity experiment introduces students to the need for, and limitations of, extrapolating animal data to humans. The aquifer feeding the Fruitvale well is found to be contaminated. This hands-on simulation illustrates how the source and the extent of the contamination are determined. Students take the roles of concerned professionals and community members and try to develop a clean-up strategy for the aquifer. Students explore how precipitation, oxidation-reduction, and single replacement reactions can be used in waste reduction and waste treatment processes.
