物理是一门以观察和实验为基础的自然学科,物理实验的考察历来是中考考察学生学习和实验能力的一个热点。近年来物理实验多以开放性、实践性、探索性为特征不断变换着,物质密度的测量经常是各地中考的一个热门考点。例1(2003年湖北黄岗市中考试题)今年6月1日三峡库区正式蓄水,6月2日文物工作者还在加紧库区的文物挖掘和搬迁工作,一位工作者发现了一古代的小酒杯。请你选用下列提供的器材测量小酒杯的密度(酒杯的密度大于水的密度,水作为辅助器材可以直接选用)。器材:量筒(内径大于酒杯的口径)、天平、弹簧秤、刻度尺、密度计、细线。(答案:①天平、量筒;②弹簧秤、量筒、细线;③量筒。)
Physics is a natural science based on observation and experimentation. Investigating physics experiments has always been a hot topic in the examination of students’ ability to study and experiment. In recent years, physics experiments have been constantly changing with the characteristics of openness, practicality, and exploratory nature. The measurement of material density is often a popular test center for local middle schools. Example 1 (2003, Huanggang Middle School Examination in Hubei) In June 1st this year, the Three Gorges reservoir area was officially filled with water, and on June 2 the cultural relics workers were stepping up the cultural relics excavation and relocation in the reservoir area. A worker discovered an ancient Small glass. Please use the equipment provided below to measure the density of the small glass (the density of the glass is greater than the density of water, water can be used directly as an auxiliary device). Equipment: Measuring cylinder (diameter greater than the diameter of the glass), balance, spring scale, scale, density meter, thin line. (Answer: 1 balance, measuring cylinder; 2 spring scale, measuring cylinder, thin line; 3 measuring cylinder.)
