《摩擦力》是一节科学探究课,教材首先利用日常生活中的具体事例,导入新课,体现了新课程从生活走向物理,激发了学生的学习欲望。然后以探究摩擦力大小与哪些因素有关为主线,让学生通过猜想、设计实验、实验探究、交流合作等,体验探讨滑动摩擦力与压力、接触面粗糙程度关系的过程。
“Friction” is a section of scientific inquiry, teaching materials first use the specific examples in daily life, into the new lesson, embodies the new curriculum from life to physics, to stimulate students’ desire to learn. And then to explore the friction with the main factors related to the size of the main line, so that students through the conjecture, design experiments, experimental exploration, exchange and cooperation, to explore the sliding friction and pressure, contact surface roughness process.
