一、课例说明“摩擦起电”这个小实验来源于小学教科版新教材《科学》四年级下册第一单元的第一课《生活中的静电现象》,该实验说明用塑料用具(如塑料自动笔、塑料直尺)与头发摩擦,可产生静电,吸起小纸屑。教学该实验旨在让学生体验生活中的静电现象,激发学生探究身边科学现象的兴趣。 First, the lesson description “friction electrification ” This small experiment comes from the primary textbook of the new textbook “Science” fourth grade volumes of the first unit of the first lesson “static phenomenon in life”, the experiment shows that with plastic utensils (Such as plastic automatic pen, plastic ruler) and hair friction, can produce static electricity, sucking small paper scraps. Teaching This experiment aims to enable students to experience the phenomenon of static electricity in their lives and stimulate students to explore the interest of scientific phenomena around them.
