密度的概念是通过实验得出来的,密度也可以应用到生活之中,所以有关密度的探究值得我们重视,也是需要灵活运用的．一、设计实验方案型例1做物理实验测物质密度时,老师拿出一架天平、一个量筒、两个完全相同的烧杯、适量的水和一些小玻璃球,让同学们利用这些器材测小玻璃球的密度,细心的小红同学发现老师沿给砝码,一问才知道是 The concept of density is obtained through experiments. Density can also be applied to life. Therefore, the inquiry about density deserves our attention and it needs to be applied flexibly. First, the design of experimental program type 1 physical experiment to measure the density of the material, the teacher took out a balance, a graduated cylinder, two identical beakers, the amount of water and some small glass balls, so that students use these devices to measure small The density of the glass ball, careful red students found the teacher along to give weight, only to ask to know
