现在，只要你有一个新的小工具，你就无法得到几天，你将在学生中受欢迎。这不是，我们中间新运行的新影响正在中间玩！我刚刚发现这场比赛中有点知道。
当我学校的每一年级几乎一半的人时，我也加入了大军。
有一天，我拿了yoked“睡觉”，看着他可以“睡觉”下面，我很开心，为什么可以“睡觉”？我母亲说，我多次问我的母亲，我不知道;我多次问我父亲，我父亲说我不知道。无意中，我用手拨打了，我看到它在滚动中，我再次拨打它，嘿！ “我知道我知道！”我发现所谓的“睡眠”原则。
事实证明，当拧紧线抛出时，向前向前转动两个半球，球体旋转，中间的中间轴承转向，这也形成了相对稳定性 - 这就是我们所说的“睡眠”。我找到了这个真理，好像哥伦布被发现在新大陆一样。啊!我太棒了，我实际上发现了戏剧中的科学真理，难怪语言老师说：“科学家正在玩！”
在学校的路上，我很高兴地走在街上，同时玩滑溜溜，我在侧面尖叫：“我发现了科学！我也是科学家！”

我一直以为鸟类和猫不能和平，但有一件事改变了我的想法。
这是一个偶然的机会，我去了我的好朋友张西杰里玩。无意中发现，她是一只叫小猫的白猫和叫小崔的老虎皮鹦鹉。我问她：“这两个小事可以生活在生活中吗？”她耸了耸肩和笑了笑：“我不明白，你会看到它！”
过了一会儿，我再次看到小鸟，突然发现这只鸟没有看到。我匆匆打电话给张曦，告诉她：“小鸟走了。让我们看看！”张西怡听了，先震惊，刚去看。
此时，我们发现鸟笼的门是开放的。拍摄鸟一定是一只小猫，我们会找到一只小猫，我发现小猫和鸟儿站在窗台里的窗台。我认为他们不像一对敌人，但更像是一对亲密的朋友。我和张曦终于将它们与中间分开。
通过这件事，我明白，虽然有些动物或人们不能在开始时居住，但只要他们彼此相爱，一双敌人就可以成为一个好朋友。

“我发现了，我找到了它！”我很快就跑到了我的母亲，并说。
“你找到了什么？”妈妈问我持怀疑态度。
“我会认识你。”我回答。
我把母亲带到阳台上，指着一个仙人掌，我没有等我。妈妈还用一个怀疑的语气说：“那不是一个好仙人掌，什么是好的发现？”
为了确认我的发现，我开始采取行动。我抓住了一个七星级瓢虫，把它放在仙人掌上，然后用放大镜看七星瓢虫只打破了一点皮肤。
我把虫子“关”放在一次性杯子里，也插入了两个小洞，让七星级瓢虫正常呼吸。
为了确保该实验的准确性，我捕获了蝗虫并根据相同的方法制备。
一切都准备就绪，只有东风，十分钟后，蝗虫吐了黑色，瓢虫吐黄。几分钟后，他们停止挣扎，在杯子里闷闷不乐，经过几分钟，突然下降，他们死了。
完成实验后，我PRaised: "Mom, do you know my discovery now?"
Mom smiled and touched my head and said: "Child, you are awesome, you can let my mother know this discovery."

橡皮筋可以打开西瓜，钢琴纸可以容纳20本书，有许多科学的神秘等待着我们在阳光下找到我们。
Example 1: Burning the leaves in the sun with a magnifying glass. We are usually in the sun in summer, with a magnifying glass, which is the most interesting thing. The light was reflected on the mirror, reflected by the strong sunlight of the mirror to the leaves, the leaves were burned by the sun, as if they were defeated, and they were lost, and they were waiting for the sanners. Since the magnifying glass is concave, it has a concentrating, so it can be burned with a leaf.
Example 2: Musical books with a piano paper. We usually use the piano paper to support a book, this experiment has done countless times. Because there is triangle in the piano paper, the triangle has stability, and so many triangles, it is also enough to hold up a book, up to 20 books, even my hands need to use the strength to take the triangle flatten .
Example 3: Make the light bulb with a wire. Let's connect the battery first. The battery is a conductive plant. The wire is a passman, and the wire and the bulb are not separable. That connection point is the small round hole, so they are three brothers, less light bubbles will not send Bright. For example, electric stations, elevators, high-speed rail and battery cars are used to start, so the world cannot be lacking.
Through these things, please let me know, whether you encounter something, you must observe.

On Sunday, I had a clip of the car in the community. When I passed the flower pool, I found that the monthly flowers have sprouted, and the branches of the small thorn have grown a piece of red leaves. Looking at these red leaves, I remembered the text "The foot of the tiger", the climbing tiger described in the article is also red, after a period of time, they will slowly become green. I think: why they are not green when they grow green, and will then slowly become green? Do you really become green?
Today, I will go to see these flowers, I find that the leaves of the month have green, and there is red, and the green leaves are relatively large. The red leaves are very small, I think: green The leaves are bigger, they are growing red and young leaves!
It's a fun phe名称。回到家后，我知道：我知道：事实证明，有一种叫华曲线的东西，所以它是红色的，有紫色，年轻的叶子很弱。紫外线很容易受到伤害，年轻叶子的红色颜料就像“太阳镜”，它可以发挥防晒霜。经过一段时间后，阳光照射在叶子上，叶绿素将逐渐变绿。

星期六早上，我和母亲一起去买蔬菜。在一个小巷里，我遇到了一个骑着三轮车的祖父。他的小三轮车充满了各种各样的植物：有一个大红月亮花，有一个小竹林，以及我从未见过的肉和肉类植物和一些植物......这么多植物都放在了台车，只是一个小型移动花园。
其中，有一罐三角李最引人注目，一群紫色燃烧在树枝上。我的母亲立即吸引了美丽的三角李子，立即向老板询问价格，最后在谈判后买了它。
爷爷看到了我，微笑着对我说：“来吧，孩子们，送你一盆小植物。”他从三轮车上养了一个小植物。 “给予，这是含羞草。”我很高兴收到了它，把它放在阳台上。
我仔细观察到这草：含羞草叶很小，就像绿色的羽毛一样，一根羽毛用口袋状的绿色插入一个小粉丝。
