求翻译：让学生体会判断物体静止和运动不能凭感觉，需要有科学方法；判断有些物质的运动如电磁波，热运动，虽然人眼不能直接看到，但可以由电磁运动、分子热运动产生的效应间接地观察。是什么意思？

Enable students to understand not to judge the feel of an object at rest and exercise, the need for scientific methods; to determine the movement of some substances, such as electromagnetic, thermal motion, although the human eye can not be seen directly, but by electromagnetic motion, thermal motio

Let students come to understand objects geostationary and movements cannot be judged by virtue of feeling judgment, there is a need to have a scientific method of some substances such as electromagnetic, thermal movement Movement, although it was not directly visible, but you can see the electromagn

Let the student realize the judgment object static and the movement cannot depend on the feeling, needs to have the scientific method; Judges some material the movement like electromagnetic wave, the heat movement, although the human eye cannot see directly, but may the effect which by the electroma

Let the students experience judging object still and motion cannot feel, the need for scientific methods; judge the movements of some substances, such as electromagnetic waves, thermal motion, although the human eye cannot see directly, but can be generated by a solenoid movement, molecular thermal
