Abstract ▼ AI-Helper

The purpose of this study is to investigate the understanding on the acid-base, acid rain and soil acidification of the elementary students. The participants in the current study were 280 6th graders from a elementary school in Gyeongnam Province. A questionnaire consists of four categories: understanding of (a) acid-base basic knowledge, (b) acid rain and (c) soil acidification. (d) In addition, students were asked to comment about the introduction of the acid rain experiment in the science textbook. The results are as follows; First, the results regarding acid-base basic knowledge. They know the classification, characteristics, and properties of acid-based solutions well but they don't know the acid-base neutralization, examples using properties and application in real life. Second, the results regarding acid rain, students know the definition and damage of acid rain but they don't know the causing substances, emission source and way of solution of acid rain for lack of knowledge. Third, the results regarding soil acidification was the well-known part for the students because they had continued learning about the soil from the lesson of acid rain. Also, we looked into the difference in gender and region about the understanding of acid-base, acid rain and soil acidification. According to the gender of the data about the understanding of acid-base, acid rain and soil acidification, the percentage of correct answers of female was higher than male's. Also we expected that urban students were higher than rural students on the understanding of acid-base, acid rain and soil acidification, but the understanding of urban students were similar to rural students. Fourth, we got positive answers and negative answers to the introduction of acid rain experiment. Most of the positive opinion were I want to know a lot acid rain experiment", followed by "It is possible to prevent the risk of the damage and It seems to having fun and new order. Most of the negative opinion were Acid rain experiment may be difficult and complicated followed by Just a theory in the book is enough, Acid rain experiment were boring and not fun, Acid rain experiment is dangerous, There are many to study in this order.

	산업혁명 이후 근대산업 발전을 수행하면서 무엇이 뒤따르게 되었나?	산업혁명 이후 근대산업 발전을 수행하면서 부차적으로 환경파괴가 뒤따르게 되었다. 개발만이 인구문제와 빈곤을 해결할 수 있는 최선책이라 생각하고 무분별한 발전을 거듭한 결과 환경오염 문제에 직면하게 되었다.
	지구환경의제 21(Agenda 21)을 채택한 「리우선언」의 행동강령 내용은?	이 회의에서 지구환경의제 21(Agenda 21)을 채택한 「리우선언」의 행동강령을 채택하였다(Yoh Soo-Dong & Park Joung-Han, 1994). ‘환경과 개발에 관한 리우선언은 스톡홀름 선언을 재확인하고 모든 국가와 모든 사람들 사이에 새로운 사회의 주요 분야와 새로운 차원의 협력을 창조 하였다. 이는 새롭고 공평한 범세계적 동반자 관계를 수립할 목적으로 모두의 이익을 존중하고, 지구의 환경 및 개발 체제의 통합성을 보호하기 위한 국제 협정 체결을 위하여 노력하며, 우리들의 고향인 지구의 통합적·상호 의존적인 성격을 인식하면서 다음과 같이 선언한다.’로 시작하여 총 27개 기본 원칙으로 구성되어 있다.
	산성비 연구는 어떻게 시작되었나?	그리고 그 후 런던스모그라는 명예롭지 못한 명성을 얻게 되었다(Kim Joon-Ho, 2007). 산성비(Acid Rain)의 연구는 1970년대에 북유럽에서 국제적인 모니터링사이트를 설치하였고 이어서 캐나다와 미국 북부에서도 시작하였다. 1979년 34개국이 가입한 UN의 유럽경제위원회(UNECE)가 주관하여 대기 오염물질의 원거리 이동에 관한 모델개발과 농도규제 강화에 조인하여 유럽과 북미에서도 황과 질소 산화물을 감소시키는 계기가 되었다.
