Home For Teachers For Students Basic Topics ... More Below! Acid Rain What is it? Acid rain is a term which you may have heard, but not quite understood. It certainly sounds very nasty doesn't it? But, unlike in cartoons, acid rain does not burn through everything that it touches! It does cause a lot of damage to buildings, plants, animals, and even humans, however. It is also a bit misleading, because even pure rainwater is slightly acidic. 'Acid rain' just means that the rain is more acidic than it should be. Before we look at what damage acid rain actually does, it is best to look at why it happens. How acid rain is formed The main elements which are responsible for acid rain, are sulphur and nitrogen (in gas form). Both of these can be caused by a number of things, including some human activities, but they are also made naturally. Human activities which produce sulphur dioxide and nitrous oxides include burning fossil fuels (like coal, and crude oil). Two things that are highly responsible for causing acid rain are power stations and factories. Although these are essential to human life in this day and age, they make large amounts of sulphur dioxide and nitrous oxides. In fact, power stations produce 70% of all of the chemicals which are responsible for acid rain.

Acid Rain What is the pH of rain in your area? Students take pH measurements for rain in their neighborhood and compare it with other students' findings. This activity is best when conducted over several weeks during a rainy time of year. Materials pH test strips 1 plastic 1-oz. cup for each student What To Do DISTRIBUTE one cup and five test strips per student. Students take cups home. Each time it rains, students COLLECT rain water in their cups. They TEST the water with one strip of pH paper, and bring the pH paper to class. DRAW a map of the neighborhood on a wall chart. Students PIN their paper on the map in the location where they collected the rain water. On successive rainy days, student PIN additional papers to the right of previous ones. As a class, DISCUSS the pH of water in the neighborhood. Did the pH change over time? Was the pH different in different areas? What are some possible reasons for this? What's Happening?

Acid Rain Written by Colin Hocking, Jacqueline Barber, and Jan Coonrod This stimulating unit fosters scientific inquiry and critical thinking skills as it harnesses the curiosity, agility, and determination of student minds to study the troubling environmental issue of acid rain. Students learn about acids, bases, and the pH scale; make "fake lakes" and determine how their pH changes after an acid rainstorm; present a play on the effects of acid rain on aquatic life; determine the effect of various dilutions of acid on seed germination; and hold a town meeting to discuss possible solutions to the problem of acid rain. A "startling statements" game challenges students' preconceptions and prompts investigation. In addition to providing much information on acid rain, the unit encourages students to analyze complex environmental issues for themselves, and emphasizes community cooperation (making it an effective companion unit to the GEMS guide Time: Eight or more 45- to 60-minute sessions.

Peggy travels to the Wolf Ridge Environmental Learning Center to learn about acid rain. ACID RAIN What causes acid rain? How does acid rain damage the environment? Is acid rain harmful to people? How does the acid get in the rain? Is there any way to stop the damage it causes? DISCUSSION Acid rain is considered by many people to be one of the most serious environmental problems of our time. It is a global problem that is gradually affecting our world. The term acid rain was coined by Angus Smith when he wrote about industrial pollution in England. Some rain is naturally acidic because of the carbon dioxide (CO2) in air that dissolves with rain water and forms a weak acid. This kind of acid in rain is actually beneficial because it helps dissolves minerals in the soil that both plants and animals need. Recently there has been some concern that the acidity of rain caused by man has increased over the last several decades. Acid rain attacks wildlife, crops and lakes. It can cause the death of forests and damage buildings and monuments. It is even harmful for human beings.

A R R F Buying Pollution Right Out of the Sky! A R R F Mission Statement The Acid Rain Retirement Fund was founded to prevent air pollution by buying it right out of the sky. The U.S. Environmental Protection Agency issues pollution allowances or permits that enable companies to emit sulfur dioxide (SO2). These permits are auctioned off to the public and a permit for one ton of sulphur dioxide has sold for $80-$1,600/ton. The Acid Rain Retirement Fund raises funds and bids alongside polluters for as many pollution allowances as our funds can buy. We then retire that pollution credit permanently. As we buy pollution allowances we remove that amount of sulfur dioxide from our ecosystem forever. As we retire more pollution allowances, the price will go up. Polluting companies will need to bid larger amounts of money to continue polluting. As the price of polluting goes up, companies will be more inclined to invest money in technologies that remove pollution before it reaches the smokestack. The Acid Rain Retirement Fund is a nonprofit corporation that uses 100% of the money donated to buy pollution allowances. No portion of a donor's money will be use for administrative purposes unless the

The corrosive nature of acid rain causes widespread damage to the environment. The problem begins with the production of sulfur dioxide and nitrogen oxides from the burning of fossil fuels , such as coal, natural gas, and oil, and from certain kinds of manufacturing. Sulfur dioxide and nitrogen oxides react with water and other chemicals in the air to form sulfuric acid, nitric acid, and other pollutants. These acid pollutants reach high into the atmosphere, travel with the wind for hundreds of miles, and eventually return to the ground by way of rain, snow, or fog, and as invisible “dry” forms.

Since then regulations have been enacted in North America and Europe to curb sulfur dioxide emissions from power plants; these include the U.S. Clean Air Act (as reauthorized and expanded in 1990) and the Helsinki protocol (1985), in which 21 European nations promised to reduce emissions by specified amounts. To assess the effectiveness of reductions a comprehensive study, comparing data from lakes and rivers across N Europe and North America, was conducted by an international team of scientists in 1999. The results they reported were mixed: while sulfates (the main acidifying water pollutant from acid rain) were lower, only some areas showed a decrease in overall acidity. It remained to be determined whether more time or a greater reduction in sulfur emissions was needed to reduce freshwater acidity in all areas. See

Acid Rain Simulation Louie Beuschlein YES! I'd like to download the original onto Microsoft Word 6.0 or higher. Introduction : This is a two day unit plan that incorporates some decision-making ideas from statistics into the science classroom. It is intended for intermediate level science students (about high school freshman age) and beyond. No previous experience with statistical analysis is required. The NCTM Statistics Standard is taken into account in this lesson by having students make use of sampling to back up a claim and by having students design (with teacher assistance) a statistical experiment to study a problem. Acid Rain Lab : Acid rain is literally acid in rain water. It is a weak acid (sulfuric and nitric) but strong enough to damage buildings and statues and harm lakes, forests, and crops. The purpose of this lab is to investigate the damaging effects of acid rain on plants. In particular, students will determine whether and/or to what extent acid rain affects the germination rate of turnip seeds. The germination rates of seeds placed in an acid rain solution will be compared with that of the controlseeds placed in distilled water. Statistical methods will then be employed to determine whether any differences in germination rates is attributable to the acid rain or if it is reasonable to explain any differences as coincidences. The acid rain solution should be a mixture of dilute sulfuric and nitric acids (about pH 4). Students, working in groups of no more than four, should sandwich exactly 25 turnip seeds (or some other type of seed) between two layers of paper toweling saturated in acid rain solution. (There should be no pools of solution.) Each group should also prepare a control Petri dish in which distilled water is used in place of the acid rain solution. The Petri dishes should then be wrapped in aluminum foil to keep them in darkness and allowed to remain undisturbed (preferably for a weekend).
