一、实验在教材中所处的地位与作用本项目设计可以弥补九年级第十四章第三节《能量的转化和守恒》一课中无演示实验的空白,利用我们身边常见的物品来演示实验,能极大地吸引同学们的注意力,极大激发我们学习物理的兴趣,调动我们学习物理的积极性,更能激发我们动脑发明的意识。二、实验原型及不足之处本节课的《想想做做》中虽有些小实验,但由于实验器材众多,准备繁琐,教师在授课时往往只是简单介绍而已,不能调动我们学习
First, the experimental position in the textbooks and the role of This project can make up for the ninth grade ninth chapter third section “energy conversion and conservation,” a lesson without demonstrating the experiment, the use of common items around us to demonstrate Experiments can greatly arouse the students’ attention, greatly stimulate our interest in studying physics, arouse our enthusiasm for studying physics, and stimulate our conscious mind. Second, the experimental prototype and shortcomings The lesson “Think and do” Although there are some small experiments, but due to the large number of experimental equipment, preparation is cumbersome, teachers are often just a brief introduction of teaching only, we can not mobilize to learn
