初中物理第一册第135页阿基米德定律实验,是学生掌握浮力定律的关键,做好这一实验,使学生正确理解浮力定律的内容,又是学生学好第六章“浮力”的关键。现将改进的实验介绍如下。一、实验装置二、实验方法按如附图所示将所用仪器装置好,并记下A、B两弹簧秤的示数;然后转动固定装置,使重物慢慢浸入水中(同时嘴杯中的水渐渐流入小简),直至浸没,再让学
Junior Middle School Physics Volume One Page 135 Archimedes’s Law is the key to students’ mastery of the buoyancy law. Doing this experiment will enable students to correctly understand the content of the buoyancy law. It is also a good lesson for students to learn the sixth chapter, “buoyancy force.” key. The improved experiment is described below. First, the experimental device Second, the experimental method as shown in the drawings to use the device is good, and record A, B two spring balance scale; then turn the fixed device, so that the weight slowly immersed in water (at the same time in the mouth cup The water gradually flows into Xiao Jian until it is immersed.
