资源描述

1松果看天气一次科学课,老师给我们上了一堂关于“天气”的课。老师说,松果可以预报天气,如果天气潮湿,它的鳞片就会紧紧地闭起来。如果天气干燥,它的鳞片就会张开。这是真的吗?我将信将疑。星期天,我去山上扫墓,在一棵松树下找到了一只松果。这只松果,浑身灰不溜秋的,一片片像鱼鳞一样的硬片像一个个小翅膀张开着,摸上去糙糙的。 “今天天气晴朗,松果当然打开。可是下雨天,松果真的会把鳞片紧闭吗?”我好想马上能揭开这个秘密。突然,我灵机一动,对了,把松果放进水里,这不就是它的人造阴雨天吗?我拿了一只杯子,放满水,把松果放进水里。松果在水里不住地往下沉,还吹着泡泡,过了一会儿,我惊喜地发现,松果真的闭起来了!太神奇了!我开心极了,我要把这只松果带到家里,以后不用再看天气预报了,有它就行!
