为深入探究液体表面张力的规律,可以利用DIS自制教具并进行必要的创新设计,从定量的角度探究液体表面张力与液体种类之间的关系,以及在水中加入表面活性剂后表面张力的变化情况,从而让学生更直观地观察到表面张力的数据变化情况。
To further explore the law of surface tension of liquids, DIS self-made teaching aids can be used to carry out the necessary innovative design to quantitatively investigate the relationship between liquid surface tension and liquid type and the change of surface tension after addition of surfactant in water , So that students more intuitive observation of the surface tension data changes.
