Acid Rain 3.5 Acid Rain. Each module focuses on a topic in the life, earth, or physical sciences. Each module consists of a student book and a teacher's guide. They work with the pH scale to see how it can be used as a tool for measuring acidity, and they investigate the long-term effects of acid rain on building materials such as steel and limestone. They also simulate the formation of acid rain by dissolving gases in water, which yields acidic solutions.
Students then plan and begin to implement a long-term study on acid rain in their area.
In the final activity, they present the findings from their study in the form of a poster, a video, or a newsletter that would be helpful and clear to the general public. Acid Rain, whichis divided into 6 activities, requires a minimum of 4 weeks to complete. A narrative section at the end of the module provides background information for students on the global aspects and the chemistry of acid rain. The wraparound teacher's guide includes a unit overview, a time line for completing the module, a materials list, background information, and teaching suggestions. Properties and changes of properties in matter.
