【教具或名称】阿基米德原理演示器。【教具装置图】【仪器的特点及用途】1.特点:本教具利用对比的方法来验证阿基米德原理。通过这样一个小小的改进,演示操作简单了很多,演示效果也非常明了,也更便于学生观察和总结浮力的规律。2.用途:验证阿基米德原理。(1)当物体浸入水中一半左右时,读出左边弹簧测力计示数的减少值和右边弹簧测力计示数的增加值,看其是否相等。
【Teaching aids or name】 Archimedes principle demonstrator. 【Teaching equipment diagram】 【Characteristics and use of the instrument】 1. Features: The teaching tools to use the method of comparison to verify the Archimedes principle. Through such a small improvement, a lot of simple demonstration operation, the demonstration effect is very clear, but also easier for students to observe and summarize the law of buoyancy. 2. Use: to verify the Archimedes principle. (1) When the object is immersed in water for about halfway, read the reduction of the left spring force gauge indication and the increase of the right spring force gauge indication to see if they are equal.
