11th Grade Chemistry
Instructors: Jeremiah Russell and Vasilii Petrenko

Introduction
Welcome to Water Quality at BLA. This is the Chemistry class website for this unit. This experimental unit was developed in a collaboration between Harvard University Graduate School of Education and Boston Latin Academy. The unit was designed using the Teaching for Understanding framework developed at Harvard.

Unit Goals
This will be a very practical unit, focused on a real-life application of Chemistry. It is designed to give you the skills and understanding to knowledgeably analyze the water quality in a body of water and to explain what has happened or is happening to produce these results. The extensive use of web resources and technology will also give you some idea of how many people and organizations are involved in work on water quality.
