冬天到了,大自然赐予我们一种天然的学习材料——雪,大家可不要轻易放过它呀!以雪为材料我们可以学到很多物理知识,下面不妨让我跟大家慢慢道来。一、观察雪花的形状,了解晶体结构“下雪啦,下雪啦!”同学们大声地欢呼着,脸上充满了激动。通过观察我们发现,雪花的基本形状是六角形,但是却几乎找不出两朵完全相同的雪花,就像地球上找不出两个完全相同的人一样。二、了解雪的保温作用“瑞雪兆丰年”是我国北方广 Winter is coming, nature has given us a natural learning material - snow, we can not let it go! With snow as a material we can learn a lot of physical knowledge, the following let me slowly come with everyone. First, observe the shape of snowflakes, understand the crystal structure “snow, snow it! ” Students shouted aloud, his face full of excitement. Through observation, we found that the basic shape of the snowflake is hexagonal, but almost can not find two identical snowflakes, just as the Earth can not find two identical people. Second, to understand the insulation effect of snow “Ruixue Mega Year ” is China’s northern wide
