近年来,中考物理试题中出现了与传统考查方式不同的新题,即开放性实验题,它主要考查学生分析推理、归纳概括等方面的综合能力.要求学生必须有扎实的基本功,能根据各种实验条件对实验器材进行筛选、组合,并灵活运用所学的物理知识进行分析和解决试题中提出的问题. 一、用给定的器材测定物理量例1请设计两种测定牛奶(milk)密度的方法,所需的器材请在下列提供的器材中选择:天平(含砝码)、刻度尺、两端开
In recent years, in the physics examinations, there have been new questions in the physics test, which are different from the traditional examination methods. They are open experimental questions. They mainly examine students’ comprehensive abilities in analyzing reasoning, inductive summaries, etc. Students are required to have solid basic skills. A variety of experimental conditions are used to screen and assemble test equipment, and the physics knowledge learned are used to analyze and solve the problems raised in the test questions. First, determine the physical quantity with a given equipment. Example 1 Design two types of milk density. The method, the required equipment, please choose the following equipment: balance (including weights), scale, open at both ends
