A Research On Developing The Low-cost Physical Innovation Experiment

Physics aims at understanding the basic structure of matter and studying the law of material motion.As the purpose of physics research determines that physic must be an experiment-based discipline,as well as the most basic and most important discipline,teachers are supposed to give full play to the role of experiments.The new curriculum advocates to use simple,inexpensive,familiar materials in life to provide students with a variety of physical experiments and explore activities to achieve interactive teaching which enables students to study in operation,experiment,as to help them realize and construct the conception and disciplines of physics and improve the science literacy of all students.In many areas,schools are facing with phenomenon as serious shortage of experimental equipment aging equipment,especially in poor secondary schools.Generally speaking,secondary experimental equipment quality is poor which brings great impact to experimental phenomena,and also a low experimental visibility.In addition,many experimental equipment is sealed so students can not see the internal structure of experimental equipment which is not conducive to the experimental explanation.Various difficulties require that teachers are able to use readily available items as experimental equipment to create experiments that are simple and easy to operate with obvious phenomenon to be observed,or are able to design experimental apparatus to aid teaching after transformation.Based on the above reasons,the focus of this project is to explore and design low-cost physics innovation experiment.The concrete research content is composed of the following parts:First of all,using documentary method to analysis,sum up and think about the status of China's physical experiment as well as to sort out,summarize and compare the domestic and international low-cost physical innovation experiments.Secondly,this paper the low-cost physics innovation experiment is discussed from the origin,the definition and the similar concept of the concept.Then it analyzes and summarizes the characteristics of low-cost physical innovation and the principles that should be followed in low-cost physical innovation experiments,following are thedevelopment and application of low-cost physics innovation experiments in physics teaching,and the effect of low-cost physics innovation experiment with case study.Finally,the focus and innovation of this project is to improve the visibility of existing experiments,reduce the cost of experiments,simplify the experimental materials,and with experimental interpretation of exercises as the starting point,it innovate 20 low-cost physical innovation experiments.The twenty low-cost physical innovation experiments are introduced in detail from the aspects of design reasons,experimental equipment,experimental steps,experimental principle,self-made experimental device diagram and data processing.The main purpose of this paper is to make up for the shortcomings of existing experiments,attaching importance to the process of doing experiments of students in secondary schools,focusing on improving students' innovative spirit and practical ability.
