A Study On Greening Design Of Chemical Experiments In The Text Book Of People's Education Press In Junior High School

From the industrialization time,the environment problem is more and more serious,therefore Green Chemistry came into being.Green Chemistry is the need of sustainable development and the future orientation of chemistry.It reduces pollution as much as possible using chemistry theory,of which the largest characteristic is eliminating pollution from the source.Countries all over the world attach much importance to study Green Chemistry and it's education.Reaching the goal of green chemistry needs numerous specialized people who know the knowledge of Green chemistry,as well as common people.Bringing up "green expert person" needs Green chemistry education.Experiments greening is an important approach for culturing the awareness of green chemistry.This paper focuses on systematic study of the design theory and practice of junior high school chemical experiments greening,culturing the awareness and method of Green Chemistry in the students.The research method of this paper mainly uses literature study,survey study and conversation study.The first chapter of this paper sorts out the external and internal developing and current situation of Green Chemistry education and chemical experiments greening.The research finds out that most studies focus on discuss how to permeate the idea of Green Chemistry,or introduce a scattered chemical experiment greening,systematic study of the design theory and practice of chemical experiments greening is rare.Then elaborates the significance of chemical experiments greening from four respects.The second chapter elaborates the concept of green chemistry and chemical experiment greening and their main characteristic.The third chapter investigates the situation of chemical experiment greening by questionnaire and conversation.The survey finds out that,junior high school teacher' and students' awareness of chemical experiments greening is weak,and practice is relatively few.The fourth chapter analyzes the contents of the chemical experiments in the text book of People's Education Press.We found that,experiments with pollution are numerous,and some experiments still have much room to improve.The fifth chapter discusses the rules and methods of experiments greening in junior high school on the basis of the text book of People's Education Press,Which may provide a reference for other school which want to study chemical experiments greening.The sixth chapter summaries and reflects this study,and we prospects for the future.
