化学实验仪器和装置图表示仪器的形象、装配、组合形式和实验的某些操作方法等。在学生作化学笔记,完成实验报告,根据实验习题的要求设计仪器装置时,都要画出实验装置图。通过绘图,有助于学生加深对化学基础知识的理解;掌握仪器装置的原理及其使用方法;同时,还有助于培养学生的实验操作能力. 现在谈谈培养学生绘制实验仪器装置图的一些做法。讲清区别,了解要求首先向学生讲清实验简图和图画有本质的不同,实验简图只要画线描式的纵断面图就可
The chemical experiment apparatus and apparatus diagram shows the image of the instrument, the assembly, the combination form, and some operation methods of the experiment. When the students make chemical notes, complete the experimental report, and design the apparatus according to the requirements of the experimental exercises, draw the experimental apparatus diagram. Through drawing, it helps students to deepen their understanding of the basic knowledge of chemistry; grasps the principles of instrumentation and how to use it; at the same time, it also helps to develop students’ experimental ability. Now let’s talk about some of the tools for drawing students’ drawing apparatus. practice. To clarify the differences and understand the requirements, we must first explain to students that there are essential differences between the experimental sketches and drawings. The experimental sketches can be drawn as line drawing vertical sections.
