三年级学生观察日记
<p> 数菜籽</p><p> 11月9日 晴</p><p> 今天科学课，李老师走进教室就问了我们两个问题：</p><p> “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？”</p><p> 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。”</p><p> “50个菜荚，16颗菜籽。”</p><p> “100多个菜荚，30几颗菜籽。”……</p><p> 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！”</p><p> 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。</p><p> 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。</p><p> ??刘 召</p><p> <span word="Today">Today</span>, <span word="science">science</span> <span word="classes">classes</span>, <span word="the">the</span> <span word="teacher">teacher</span> <span word="asked">asked</span> <span word="us">us</span> <span word="to">to</span> <span word="walk">walk</span> <span word="into">into</span> <span word="a">a</span> <span word="classroom">classroom</span> <span word="on">on</span> <span word="two">two</span> <span word="issues">issues</span> : "<span word="You">You</span> <span word="guess">guess</span>.<span word="Rape">Rape</span> <span word="about">about</span> <span word="the">the</span> <span word="number">number</span> <span word="of">of</span> <span word="dishes">dishes</span> <span word="for">for</span> <span word="each">each</span> <span word="pod">pod</span>? <span word="how">how</span> <span word="many">many</span> <span word="there">there</span> <span word="are">are</span> <span word="in">in</span> <span word="each">each</span> <span word="pod">pod</span> <span word="vegetables">vegetables</span> <span word="rapeseed">rapeseed</span>?
