教学资料[八年级物理上]第六章 质量与密度
第六章 质量与密度
本章概述与课程标准要求
本章内容属于课程标准的科学内容中第一个主题“物质”下的一个二级主题。课程标准要求：
（1）初步认识质量的概念，会测量固体和液体的质量。
（2）通过实验，理解密度的概念，尝试用密度知识解决简单的问题。能解释生活中一些与密度有关的物理现象。
（3）了解物质的属性对科技进步的影响。
课本从日常生活常见的现象入手，带领学生走进多彩的物质世界。本章贯穿两个重要的物理量——质量和密度。通过学习质量的概念和天平的使用，探究密度的概念，以及开展密度知识交流会的活动，使学生对物质有了进一步的定量认识。在这部分内容的学习中，应该着重让学生亲自经历各种探究过程，在实际操作过程中总结规律，学习知识，发展解决实际问题的能力。
天平：是测量质量的工具。中学实验室常配备J0105型托盘天平。称量500g，感量0.5 g。
微型物理实验室：力学学具由组合天平、标准弹簧秤、量筒、滑轮、斜面等装置组合而成。可用于学生开展实验探究。
本章实验器材
量筒：用于测量液体或固体的体积。常用量筒为500ml、250ml、100ml、50ml。
刻度尺：刻度尺用来测量长度。最小刻度一般为1mm。
