高中一年级第七章固体和液体的性质一、教学要求 1.知道固体可分为晶体和非晶体,知道晶体又可分为单晶体和多晶体,了解单晶体、多晶体和非晶体在外形上和物理性质上的区别; 2.了解液体的表面张力,知道它是怎样产生的。二、对几个问题的说明 1.关于晶体和非晶体以及单晶体和多晶体学生在学习初中物理时已经知道晶体具有确定的熔点,而非晶体则没有确定的熔点。对于这一点,在教学中应予以复习和强调。
High School First Grade Chapter 7 Properties of Solids and Liquids 1. Teaching Requirements 1. Know that solids can be classified as crystalline and amorphous. Know that crystals can be divided into single crystals and polycrystals. Learn about the appearance of single crystals, polycrystals, and noncrystals. Differences in physical properties; 2. Understand the surface tension of the liquid and know how it is produced. Second, the description of several issues 1. About crystal and non-crystal and single crystal and polycrystal students in the learning of junior high school physics have known that the crystal has a certain melting point, but the crystal has no fixed melting point. For this, it should be reviewed and emphasized in teaching.
