Acid Rain and pH Visualization LabThis lab seeks to give students a more concrete understanding of the pH scale and how it applied to acid precipitation. Most students are familiar with the concept of the pH scale, and understand how to read it. However, few appreciate the exponential nature of the scale. For example, an acid of pH 4.0 is ten times stronger than an acid of pH 5.0. Students will perform a titration of eight simulated rainwater samples with sodium hydroxide (NaOH) to get a more concrete sense of how much stronger of an acid different pH levels are.

Air Pollution Lecture PowerpointThis air pollution Powerpoint lecture begins with two case studies: the Donora fluoride fog disaster, and the great London Smog of 1952. These incidents are used to illustrate the dire health and environmental effects of air pollution when it is unregulated. The rest of the Powerpoint lecture centers around the passage of the Clean Air Act and its subsequent amendments. The specific air pollution molecules, such as sulfur dioxide and carbon monoxide, that are controlled by this act are compared. Students will learn the primary sources of each pollutant and what steps have been taken to reduce the emissions of each.
Air Pollution Lecture Notes OutlineTaking efficient notes can be a big challenge for many students, especially when working from a Powerpoint lecture. This outline gives students a means to take notes that guides them toward important concepts and avoids the pitfalls of writing word-for-word or simply not taking notes at all. The outline is written as a series of questions, fill-in-the-blanks, or diagrams.
Air Pollution Study GuideOnce the instruction for the unit is completed, students can complete this study guide to aid in their preparation for a written test. The study guide is divided into two sections: vocabulary and short answer questions. The vocabulary is taken directly form the lecture, sequentially. The short answer questions are meant to model the type they may see on the exam.
