Abstract: Much of Mesoamerica's rich cultural heritage is slowly eroding because of acid rain. Just as water dissolves an Alka-Seltzer tablet, acid rain erodes the limestone surfaces of Mexican archaeological sites at a rate of about one-half millimeter per century (Bravo et al. 2003). A half-millimeter may not seem like much, but at this pace, a few centuries of acid rain is sufficient to destroy paintings, frescoes, and other fine detail in ancient art and architecture. This article describes an interdisciplinary educational supplement designed for middle-and high-school classrooms called "Acid Thunder: Saving El Tajin from Acid Rain." This supplement came about as a result of research conducted by the University of Wisconsin-Milwaukee in collaboration with the National Autonomous University of New Mexico (UNAM). The supplement is in the form of a Webquest, an inquiry-oriented exercise focusing on analysis, synthesis, and evaluation, for which the Internet is the primary information source. "Acid Thunder" is two-week activity that follows the work of a group of UNAM scientists who are researching many aspects of acid rain, including chemistry; meteorology; effects on plants, animals and materials; and measurement. "Acid Thunder focuses on the El Tajin archaeological zone, an important monument site in the state of Veracruz, Mexico. The Webquest is designed as an interdisciplinary unit to facilitate standards-based, active exploration in science and social studies. With "Acid Thunder", teachers have the significant opportunities to integrate topics in science and social studies and can offer students a stimulating experience likewise students can research features of an ancient Mesoamerican culture and compare it with other pre-Hispanic civilizations like the Mayas or Aztecs. In addition, this Webquest serves the important function of demonstrating to students how classroom walls are no longer a boundary for classroom-based activities. (Contains 2 figures.)

Descriptors: Environmental Education; Climate; Science Education; Problem Based Learning; Constructivism (Learning); Conventional Instruction; Experimental Groups; Control Groups; Rural Schools; Statistical Analysis; Content Analysis; Grade 7; Student Attitudes; Interviews; Visual Aids
Abstract: In this study, with selecting the focusing point of the problem as the availability of cartoons, the teaching of global environmental problems according to the constructivist theory is investigated on the 7th graders in rural areas. This study is restricted with the global warming (G), ozone depletion (O) and the acid rain (A) problems. In the study, a pre-test post-test control group design was used. There are 40 students whose ages range from 13 to 14 years. While experimental group was taught by means of problem based learning (PBL), traditional teaching methods were applied to the control group. Data were collected with the pre-test, post-test, and the interviews after the study. The validity of the experimental method is analysed with a t-test. Data collected by the methods of interviews were evaluated by content analysis. According to the results of statistical analysis, it can be seen that the experimental method is much more effective than the traditional method for teaching global environment problems. As a result of the content analysis, the experimental group students (70 %) and the control group students (15 %) evaluated that global warming, ozone depletion and acid rain (GOA) were accepted as global problems. Students in the experimental group emphasized that GOA, global warming-ozone depletion (GO) and G affected their living areas; on the other hand, students in the control group determined that they were affected by only G. Students in the experimental group pointed out that a person should do something to solve the global environmental problems. Both experimental group (89.4%) and control group (10.6%) suggested that technology has a vital role to solve global environment problems. Finally, the students in the experimental (85%) group think that method is amusing. From these results, it is seen that students' knowledge and consciousness about global environmental problems increase with the using of this experimental method, and at the same time it is seen that with this study they can realize their share of improving environment easier than before.

3. Greek Primary School Teachers' Understanding of Current Environmental Issues: An Exploration of Their Environmental Knowledge and Images of Nature (EJ760009)
Michail, Sirmo; Stamou, Anastasia G.; Stamou, George P.
Science Education, v91 n2 p244-259 Mar 2007

Journal Articles; Reports - Research
Descriptors: Elementary School Teachers; Misconceptions; Information Sources; Pollution; Climate; Environmental Education; Environmental Influences; Natural Resources; Knowledge Level; Mass Media; Science Education
Abstract: In this article, the Greek primary school teachers' understanding of three current environmental issues (acid rain, the ozone layer depletion, and the greenhouse effect) as well as the emerging images of nature were examined. The study revealed that teachers held several environmental knowledge gaps and misconceptions about the three phenomena. Using the media as major environmental information sources, in which environmental issues are constructed as environmental risks, teachers are being environmentally educated in lay and not in scientific terms. Moreover, the image of nature emerging from their ideas about the three environmental issues is that of the romantic archetype, which prevails in postindustrial societies. Such a view, though, gives a conceptualization of nature as balance, under which the greenhouse effect and acid rain are seen as exclusively human-induced "disturbances."

Descriptors: Pollution; Chemistry; Science Activities
Abstract: The term acid rain describes rain, snow, or fog that is more acidic than normal precipitation. To understand what acid rain is, it is first necessary to know what an acid is. Acids can be defined as substances that produce hydrogen ions (H+), when dissolved in water. Scientists indicate how acidic a substance is by a set of numbers called the pH scale. The lower the pH number of the substance, the more acidic the substance is. Acid rain forms when pollutants produced by cars and factories enter the atmosphere and become dissolved in the water found in air. Acid rain can harm trees, soil, fish, and other living things. Acid rain has damaged many forests and lakes in Canada and the northeast United States. Acid rain can also damage manmade structures over time. Many statues and buildings around the world are made of a type of rock called limestone, which is easily damaged by acid rain that wears the stone away. This article provides a class activity which students can perform to observe the effect that acid can have on statues and buildings.

No
Descriptors: School Libraries; Student Projects; Student Research; Genealogy; History Instruction; Local History; Facilities
Abstract: Every day everyone drives by local burying grounds and cemeteries, glancing at history while everyone passes. All over America valuable information is being washed away by acid rain, destroyed by vandalism, or simply forgotten and neglected. Students can help stop this destruction and loss of data with a cemetery project-based experience. For many teachers and library media specialists, connecting history to the lives of students can be an arduous task. With a project of this type, students can learn essential research skills, proper citation formats, and improved technology skills while following standards-based learning objectives and learning about the history of their community. In this article, the author talks about some practice projects online and how to create one's project.

7. Creating a Star: The Science of Fusion--Fusion Power Would Not Contribute to Global Warming, Acid Rain, or Other Forms of Air Pollution, nor Would It Create Long-Lived Radioactive Waste (EJ710709)
Baird, Stephen L.
Technology Teacher, v64 n5 p17 Feb 2005
Descriptors: Energy; Fuels; Physics; Scientific Research; Technological Advancement
Abstract: Fusion is the process that powers the sun and the stars. Since the 1950s, scientists and engineers in the United States and around the world have been conducting fusion research in pursuit of the creation of a new energy source for our planet and to further our understanding and control of plasma, the fourth state of matter that dominates the known universe. Generating power through nuclear fusion holds the tantalizing promise of unlimited supplies of clean energy. By the middle of the next century, the world's population will double, and energy demand will triple. In this article, the author states that there are still scientific and technological advances that have to be made before the dream of commercial electricity production will become a reality.

9. What Is Acid Rain? (EJ721661)
Likens, Gene E.
Science and Children, v42 n3 p52 Nov-Dec 2004
Descriptors: Fuels; Pollution; Environmental Education
Abstract: Acid rain is the collective term for any type of acidified precipitation: rain, snow, sleet, and hail, as well as the presence of acidifying gases, particles, cloud water, and fog in the atmosphere. The increased acidity, primarily from sulfuric and nitric acids, is generated as a by-product of the combustion of fossil fuels such as coal and oil. Now, long-term data collected from the Hubbard Brook Experimental Forest are available to provide a clear relationship among sulfur dioxide emissions and concentrations of acid forming sulfate in atmospheric deposition and in surface waters.

Skamp, Keith; Boyes, Eddie; Stanisstreet, Martin
Research in Science Education, v34 n3 p313-342 Sep 2004
2004-09-00
Descriptors: Pollution; Student Attitudes; Environmental Education; Climate; Environmental Standards; Student Responsibility; Grade 6; Grade 10; Grade 8; Misconceptions; Environmental Influences
Abstract: The results of a large scale (N=1001) cross-sectional (Years 6, 8 and 10) study of students' ideas about the composition of unpolluted air, the nature of air pollution, the biological consequences of air pollution, and about acid rain and the Greenhouse Effect are reported. A range of persistent alternative conceptions were identified, in some instances with increasing frequency across grades. Students' attitudes towards education, obligation, legislation or taxation as a way of reducing air pollution were determined; the first two were the most favoured. Increased attention to particular gas and air pollution concepts is recommended; other pedagogical implications are discussed.
