today, science classes, the teacher asked us to walk into a classroom on two issues : "you guess.rape about the number of dishes for each pod?

　　how many there are in each pod vegetables rapeseed? "the teacher said just now.we will go on to answer : "21 dishes dioxin, 20 were rapeseed. "" vanilla 50 dishes.rapeseed 16 satellites. "" vanilla more than 100 dishes, a few of rapeseed 30. ": : the teacher smiled mysteriously and said :"we have to solve this problem or to the fields!" we have come to the edge, a look at two days ago,here was still golden, every tree branches rape of a month full of dishes full unity of the pod looks a bit shen.careful observation pod vegetables, i saw so many seeds of its legs "while" a convex circular swelling, and the sharp tip;has the "cloak" of dioxin -- vegetables, seeds inside the circle liuliu, like so many small shiny glistening pearls, very pretty.theirs was a combination of me and a few qiuqi, two at several quickly finished several lengthy rape.

　　when i find that the tree came over 400 pages of this strain of dioxin in food,they're helping to hang on branches stems.i have to adopt a vegetable dioxin from above, catching 27 rapeseed augmented.

　　三年级学生观察日记

　　数菜籽

　　11月9日 晴

　　今天科学课，李老师走进教室就问了我们两个问题：

　　“你们猜一猜，每棵油菜上大约有多少个菜荚?每个菜荚里有多少颗菜籽?”

　　老师的话刚说完，大家就七嘴八舌地回答起来：“21个菜荚，20颗菜籽。”

　　“50个菜荚，16颗菜籽。”

　　“100多个菜荚，30几颗菜籽。”……

　　李老师神秘地笑了笑，说：“我们还是到田里去解决这个问题吧!”

　　我们来到田边，一看，二十多天前，这里还是一片金黄，现在每一棵油菜的枝条上结满了一个个饱满的菜荚了，看起来有点沉。仔细观察菜荚，只见一颗颗种子胀满了它的“外衣”，圆鼓鼓的凸了出来，顶端尖尖的;剥去“外衣”——菜荚，里面的种子圆溜溜的，像一颗颗小珍珠晶莹发亮，十分好看。

　　我和仇琦两人一组合作数，我们两个两个地数，很快就数完了三株油菜。当我数到最后一棵的时候，大吃一惊，这株足足有400多个菜荚，它们密密麻麻地挂在茎上伸出的枝条上。我还从上面采来了一个菜荚，剥开数了数有27颗菜籽。
