DESCRIPTION

Acid Rain: What is it and what does it do?. Acid Rain. When pollution from cars and factories enters the air it reacts with water to lower the pH of water (pH measures acidity). Rain water has a pH of 5.2 Acid rain has a pH of 4. - PowerPoint PPT Presentation

These acids lower the pH of the rain water. To give children an idea of how low a pH of 4 is, lemon juice is 2, saliva is 6, distilled water is 7, baking soda is 9 (basic). Most acid rain is derived from the midwest area where lots of industry occurs. Combined with easterly-moving weather patterns, this means that the east coast is the most damaged by acid rain in the United States. While this is not Walla Walla, do they have family and friends there? What about cool places they hope to go someday like New York city? Make acid rain relevant to their lives even if they are not directly affected by it now.*Use this to help better illustrate acid rain.*On all the pictures, as the children what effects they see and if its similar to what they observed with the garden experiment. Explain that acid rain doesnt just hurt plants, it also lowers lake and stream pH harming fish, damages soil, and erodes statues.*Make the educator-consumer-active citizen connection for the kids. Help them understand that doing just one of the things above is good, but incomplete. Explain to them that despite Walla Walla not being an area that gets acid rain deposition, they have family that live in areas that do, or might some day want to live somewhere affected by it. Make them understand the connection their local experiment has to national issues and help them understand why they should care.*Just so you have sources for those extra brainy kids!*</p></li></ul>
