建立物质构成的粒子观,就是要求同学们用粒子的观念去学习化学,初步认识化学现象的本质,从五彩缤纷的宏观世界步入充满神奇色彩的微观世界;从身边的生活现象和简单的实验入手,认识物质的粒子性,理解有关物质构成的微观概念;运用物质构成的初步知识解释一些简单的化学现象;通过对问题探究和实践活动,提高想象能力和创新能力． To establish a particle view of matter, students are required to use the concept of particles to learn chemistry, to first understand the nature of chemical phenomena, and to step into the microscopic world full of magical colors from the colorful world; to start with the life phenomena and simple experiments around them. To understand the particle nature of matter, to understand the microscopic concept of the composition of matter, to use simple knowledge of the composition of matter to explain some simple chemical phenomena, and to improve imagination and creativity through inquiry of problems and practical activities.
