学习目标1.经历从许多与力相关的生活现象归纳出力的基本概念的过程并了解力的概念。2.通过实验感受力作用的相互性。3.通过常见事例和实验认识力的作用效果。4.了解力的三要素。了解力的单位。能用力的示意图描述力。5.通过实验使物体受力后产生不同的作用效果来了解力的三要素。通过画力的示意图,从而学会描述力。6.通过画力的示意图,养成良好的学习习惯和实事求是的科学态度。重点1.学生经历和体验归纳力的初步概念的过程。
Learning Objectives 1. To go through the process of generalizing the basic concepts of force from many force-related life phenomena and to understand the concept of force. 2. The reciprocity of experimental sensibility. 3 through common examples and experimental effect of cognitive effect. 4. Understand the three elements of power. Understanding unit. Powerful schematic to describe the force. 5 through experiments to force the object to produce different effects to understand the power of the three elements. Through the schematic diagram of the power of painting, so learn to describe the force. 6 through the sketch of the power to develop good learning habits and realistic scientific attitude. Emphasis 1. The process by which students experience and experience the initial concept of inductive force.
