我的家庭观察日记作文【一】
今天，我还没到窗台前，就闻到一股臭味，像是什么东西发酵的`味道。起先，我还以为是窗外飘进来的味道，可我一走到窗台，我大吃一惊，只见水面上飘满了白沫，在碗面上飞着许多小飞虫，有许多白灰色的枝杆伸出积满白沫的水面，就像雪地里的几株树杆，我断定，豆芽了，它们不吭一声地离开了人世。我端起碗一看，绿豆的芽已变成了咖啡色，看来，现在已经无药可救了。
“绿豆芽，祝你们在天堂生活愉快！”

我的家庭观察日记作文【三】
蜗牛是动物界微不足道的小家伙，说它小，也确实够小了！但它却给我们的生活带来了乐趣。
今天，我好好地观察了它一番。
它有一个又软又硬的壳，为什么说它又软又硬呢？有人会问。让我这个“小博土”来告诉你吧！因为我把它用剪刀轻轻剪了下，就破了；而我用手摸了摸，可硬了。
“咦，它的身上还背着像旋一样的壳呢，它的壳上是左旋还是右旋呢？”我自言自语地说。我仔细地看了看，高兴地叫起来：“是右旋，是右旋！不是左撇子！”我象是得了冠军似的为蜗牛感到兴奋！高兴之余，我想起蜗牛的旋有几圈呢？我细心地数起来：“一圈，二圈……”“哇，有七圈啊！”我被吓得目瞪口呆！
壳观察完了，我得观察身体了。
“为什么蜗牛身体是黄的？”我心中一直停留着这个问题。原来，黄色的是蜗牛的皮肤，皮肤的颜色跟周围环境有关，现在是秋天，所以蜗牛是黄色的。
