星期天早上，我打开冰箱拿鸡蛋，准备煎一个荷包蛋。我猛地一拉，发现横卧的几只鸡蛋经不住猛烈的摇晃，流出了鲜艳的蛋黄和透明的蛋液。而竖卧的鸡蛋却完好无损。这是为什么呢？我跑去问正在看报纸的爸爸，爸爸说：“你自己做个实验就明白了。是这样做的……”我为了探个究竟，照爸爸说的做了一个小实验：我拿了一大团橡皮泥，分成四小团。上面竖直放上四只鸡蛋和一块木板，再放上《新华字典》和《小学生作文》两本书。让我惊讶的是，结果鸡蛋毫发未损！我想如果鸡蛋是横放又是什么结果呢？动脑不如动手，我就在橡皮泥上横放了四只鸡蛋。哎！让我没想到的是：刚放上一本《新华字典》，鸡蛋就四分五裂了！是不是这几只鸡蛋的壳刚好是薄的呢？不如换别的蛋试试看！但结果还是一样。我再想：一边放竖的蛋，一边放横的蛋，在横放的鸡蛋下垫点橡皮泥，让这两只鸡蛋一样高，结果又是怎么样呢？我又做了个小实验，结果放上一只铅笔盒，原封不动，又放上一只瓷盘，横放的鸡蛋“啪”地一声就碎了。这是为什么呢？我仔细思考：这蛋是不是都是两端壳硬，中间壳软呢？我这想法是对还是错呢？如果是对的，为什么是两端壳硬、中间壳软呢……我一下子想出了好多问题。后来，我翻翻科学书，查了查资料，又问了问老师，得出了一个结论：我的想法是错的。正确的答案应该是：把鸡蛋横放，一压就破了，如果把它竖起来，就不易破，这说明同样的材料的强度大小，决定于形状的不同。这就像拱桥和平桥，两者所能承受的重量就不同，拱桥能承受更大的重量。 经过做这个实验，我养成了遇见问题就要仔细思考，争取弄懂的好习惯。

蚂蚁为什么不会迷路蚂蚁，相信大家都很熟悉。那又有谁能真正地了解蚂蚁呢？蚂蚁为什么不会迷路呢？带着这个问题，我查阅了一些书籍。书上说，蚂蚁从蚁穴出发到达目的地后，沿途会留下一些气味，返回蚁穴。用触角相互碰一下，通知其他的蚂蚁。科学家曾经就这个问题作了一个试验。科学家先确定一只蚂蚁，将他沿途到达目的地的地方用力擦干净。当这只蚂蚁返回时，在被擦去气味的地方突然间停了下来。原地边转圈边寻找着什么。从而得到蚂蚁是靠气味来辨别方向的。我为了证实这个结论，我做了个试验。我首先准备了一个十厘米左右的细小树枝，在树枝的一头放上一个诱饵——小糖果。我把这个装置放在一个蚁穴附近。不一会儿，有一只蚂蚁出来探路了。我把他引上木棍后，他到达了糖果的地方，仿佛在闻一闻、嗅一嗅。我趁此机会将木棍的中断部分截下一厘米的木棍。当这只蚂蚁返回的时候，就在被截去的地方左转右转，就是找不到回家的路。 过了一会儿，我又重复了上面的试验，蚂蚁仍然没有找到回家的路。通过这两次实验，我终于知道蚂蚁为什么不会迷路的秘密了。原来蚂蚁是根据气味来辨别方向的。 知道了蚂蚁的这一秘密后，我在想：是否我们可以制作一种蚂蚁报警器呢？当蚂蚁走到报警器附近时，报警器就能“闻”出蚂蚁的气味，然后发出鸣叫声，让我们知道蚂蚁跑到橱柜里了或其他地方 。

WASHINGTON - President-elect Barack Obama was an invisible force as foreign leaders and Congress convened separately in Washington, the economy at center stage.One sentiment runs below the crosscurrents as a summit of world leaders wrestled with a global crisis this weekend and Congress in the week ahead struggles with rising unemployment and an ailing auto industry: What would Obama do?Obama stayed away, ensconced in Chicago, unwilling to make any public show of political influence before he is sworn in to office Jan. 20. Indeed, his break with Congress will be complete on Sunday when he officially resigns his Illinois Senate seat.Story continues below ↓advertisement | your ad hereObama was especially cautious about the economic summit, letting President George W. Bush represent the nation. But in the Democratic radio address Saturday, Obama subtly made the point that the summit was only a beginning. "I'm glad President Bush has initiated this process because our global economic crisis requires a coordinated global response," he said.Obama was more direct with Congress. He urged lawmakers to "pass at least a down-payment on a rescue plan that will create jobs, relieve the squeeze on families, and help get the economy growing again.""If Congress does not pass an immediate plan that gives the economy the boost it needs, I will make it my first order of business as president," Obama said.No major economic breakthroughs are expected and, for Obama, the challenges he faces upon becoming president might seem a bit clearer after the foreign leaders and Congress pack up and go home."You can imagine the difficulty from the perspective of the participants," said David Lewis, an expert on the presidency at Vanderbilt University. "You don't want to put a lot of effort into doing something when you know that the arrival of a next administration might undo all the work you have done or might undercut an administration that you want to see what they have to offer."Still, summit participants on Saturday embraced broad principles to strengthen international monitoring of markets and to beef up rules about how companies value their assets, key steps designed to identify risky investing.Stocks’ wild ride should continue this weekNewsvine: Discuss the crisisAbsent Obama is front-and-center in capitalThose still in stocks resigned to tough it outAt summit, proposals but few concrete stepsTop GOP senators oppose automaker bailoutRetail sales plunge by a record amountWall Street ends turbulent week sharply lowerLooking ahead to the new president, German Chancellor Angela Merkel said of Obama: "I have not the slightest doubt that we will be able to proceed along the way that we set out today. This is a reasonable approach that the new president will surely support."While Obama has laid out an agenda for tackling the economic gloom, the question facing Congress and the international community is whether his prescriptions will be enough.Obama has proposed a $175 billion economic recovery plan that includes tax cuts, help for states and spending on public works nationwide. But already, economists, labor leaders and some members of Congress are tossing around figures of $300 billion or more. Obama aides are signaling flexibility.
