10 Something’s Really Up

CHAPTER TEN Something's Really Up Electrochemistry (noun). A branch of chemistry dealing with metals. An electrochemist figured out how to make the coating on your sunglasses and the microchip in your computer. THE NEXT MORNING, Tuesday, I was skipping down the hall to class. Because last night, I had figured out my Rube Goldberg machine! It was going to be so much fun to make. There was going to be stuff like a ramp, a pebble, dominoes, and Birdie's strawberry, of course! Behind me, Elijah hurried to catch up. "Wow. Kate," he called out. "You're in a rush." "Yup!" I whirled around to wait for him. Then I explained to Elijah how I was going to put lemon batteries and the calculator into a Rube Goldberg machine. "I thought about it all last night. I'm going to use a few lemons to power a little fan, which is chemistry and engineering. Then blow a pebble down a ramp, which would be earth science and geology. The pebble will knock into dominoes, which is physics. And the dominoes will push the strawberry—which is botany, you know, the study

第十章出了问题电化学（名词） 金属化学研究金属的一个分支 一位电化学家想出了制造太阳镜涂层和电脑微芯片的方法。 第二天早上，星期二，我蹦蹦跳跳地穿过走廊去上课。 因为昨晚，我弄明白了我的鲁布·金伯格机器！制作它会非常有趣。 当然，会有斜坡、鹅卵石、多米诺骨牌和小鸟的草莓之类的东西！在我身后，以利亚急忙追了上来。 “哇。凯特，”他喊道。 “你太着急了。”“是的!”我转过身来等他。 然后我向以利亚解释，我要把柠檬电池和计算器放进鲁布·戈德堡机器里。 “我昨晚一直在想这件事。 我要用几个柠檬来驱动一个小风扇，这是化学和工程。 然后往斜坡上扔一块石头，这就是地球科学和地质学。 鹅卵石会撞成多米诺骨牌，这是物理学。 多米诺骨牌会推动草莓，这是植物学的研究

of plants—off a ledge into a cup of water. The water will overflow, wetting a piece of tissue paper that's underneath it. Through capillary action (and more chemistry!), the spilled water will creep up the tissue paper that has been pulled tightly over a small vertical plastic arm. The water will force the tissue paper to break, and then the little plastic arm will pop up and push a button to turn on the vertically standing calculator, which will also be powered by lemons!" "So cool!" Elijah gushed. "It's kind of like a game we have at home—Mousetrap." "That's just what Birdie said!" I had called her about the machine idea last night. "I just love that I'm getting so many branches of science into my

把植物从窗台上摘下来放进一杯水里。 水会溢出来，弄湿它下面的一张纸巾。 通过毛细管作用（和更多的化学反应！），溢出的水会爬上紧紧拉在一个垂直的小塑料臂上的纸巾。 水会使薄纸破裂，然后小塑料手臂会弹出，按下按钮，打开垂直站立的计算器，它也将由柠檬供电！”“太酷了!”以利亚涌。 “这有点像我们在家里玩的游戏——捕鼠器。” “伯蒂就是这么说的！”昨晚我打电话给她谈了机器的想法。 “我很高兴我能把这么多的科学分支纳入我的

demo. And I can explain all of them to Dr. Caroline. It's like I'm doing six projects in one!" As I stood next to the water fountain, Rory slunk by and gave me a very strange look. His eyebrows scrunched weirdly, as if I had my shirt on inside out or something. "What's with him?" Elijah shrugged. "No clue." "Well, I know what's up with me. I've got everything I need for my machine, including lemons, a ramp, dominoes, a cup, a wax strawberry, tissue paper, Ms. Daly's calculator, and a plastic arm." I twirled my grocery bag full of supplies. Then I whispered, "This time, I'm putting everything in the very back of my cubby in our classroom. That way nothing can fall out. And it would be harder for someone to grab." "Do you think someone actually took the lemons yesterday? I mean, sure, if you wanted to make lemonade. But you'd need sugar, water, and a pitcher. What kid would have all of that?" "Memito," I blurted. "Oh, c'mon. Do you really think he would've done that?" I thought about it. He loved anything to do with cooking and recipes. But I didn't think he would take my lemons. "Nah." I shook my head. "I

演示。我可以把这些都解释给。 卡洛琳。就像我在一个项目中同时做六个项目一样！”当我站在饮水机旁时，罗里悄悄地从我身边走过，用很奇怪的眼神看了我一眼。 他的眉毛古怪地皱了一下，好像我把衬衫穿反了似的。 “他怎么了？”以利亚耸耸肩。 “不知道。”“好吧，我知道我怎么了。 我已经准备好了机器所需的一切，包括柠檬、斜坡、多米诺骨牌、杯子、草莓蜡、纸巾。 戴利的计算器，还有一个塑料手臂。” 我旋转着装满物资的购物袋。 然后我低声说：“这次，我要把所有的东西都放在我教室小柜子的最后面。 这样什么也不会掉出来。 这样别人就更难抢了。” “你认为昨天真的有人拿走了柠檬吗？” 当然，如果你想做柠檬水的话。 但你需要糖、水和一个水罐。 什么样的孩子会拥有这一切？”“备忘录，”我脱口而出。 “哦,来吧。你真的认为他会那样做吗？”我想了想。 他喜欢一切与烹饪和食谱有关的东西。 但我没想到他会拿走我的柠檬。 “不。”我摇了摇头。“我

don't think so." I looked both ways down the mostly empty hallway. We had driven in early with Mom. "I want to put the stuff back in the classroom without anybody seeing." Elijah made a face. "So, I'm not anybody?" "You're definitely somebody. You're one of my best friends. That's why you don't count as a suspect." "Well, that's an acceptable answer," he said, and looked pleased. He followed me into the classroom, where our teacher, Mrs. Eberlin, was stapling worksheets. "You two are in bright and early." "Yes," I said. "Mom had an early meeting and we came with her. Plus, I wanted to put some of the materials for my STEM Night project away. To keep them safe." "Good idea. How's the project going?" asked Mrs. Eberlin. "Great," I said. And it was true. I was going in a different direction. But it felt so right. Mrs. Eberlin neatened her stack. "How about you, Elijah?" "Good." He pulled his drumsticks out of his backpack. "Getting graded to drum. Can't complain."

我可不这么认为。”我朝空荡荡的走廊两边看了看。 我们和妈妈一早就开车来了。 “我想把这些东西放回教室里，不让任何人看到。” 以利亚做了个鬼脸。“那么，我不是什么人物了？”“你绝对是个大人物。 你是我最好的朋友之一。 这就是为什么你不被视为嫌疑人。” “嗯，这是一个可以接受的答案，”他说，看起来很高兴。 他跟着我进了教室，我们的老师埃伯林夫人正在那里订书机。 “你们俩来得真早。” “是的，”我说。“妈妈很早就开了个会，我们跟她一起去了。 另外，我想把我的STEM之夜项目的一些材料收起来。 保证他们的安全。”“好主意。 项目进行得怎么样了？”埃伯林太太问。 “太好了，”我说。这是真的。 我走的是另一个方向。 但这感觉太棒了。埃伯林太太整理了她的书堆。 “你呢，以利亚？”“好”。 他从背包里拿出他的鸡腿。 “被分级为鼓手。没什么可抱怨的。”

"It's always better to do what's in your heart," Mrs. Eberlin said with a smile. Luckily for me, I loved science—all of it. And I loved that even with the Rube Goldberg machine, I was still doing some chemistry. Learning about how electrons move through metals was a branch of chemistry called electrochemistry. After gently stuffing all of my supplies, including the strawberry, in the back of my cubby, I turned to Elijah. "I'm going to meet up with Birdie by the basketball court. Want to come?" "Sure," said Elijah. "See you soon," said Mrs. Eberlin. All morning, all I could think about was my project. School dragged except for when we got to language arts. That was because we were going to write haiku poems about our STEM project. "And you get to write them with these," said Mrs. Eberlin, shaking a cardboard box mailer. "My sister Lucia mailed me pens from Buenos Aires." "Yay!" cried Birdie. Mrs. Eberlin held up different kinds and different colors. "My sister owns an art supply store. And these are some extra mismatched ones that she had lying around. They're a present for doing such good work so far on your language arts

“做自己心里想做的事总是更好的，”埃伯林太太笑着说。 幸运的是，我喜欢科学——所有的科学。 我很喜欢这一点，即使有了Rube Goldberg机器，我仍然在做一些化学研究。 研究电子如何在金属中运动是化学的一个分支，叫做电化学。 轻轻地把我所有的东西，包括草莓，塞进我的小柜子后面，我转向以利亚。 “我要去篮球场和小鸟见面。 你想来吗？”“当然可以。”以利亚说。 “再见，”埃伯林太太说。 整个上午，我满脑子想的都是我的项目。 除了语言艺术课，学校很拖沓。 那是因为我们要写关于STEM项目的俳句诗。 “你可以用这些来写，”埃伯林太太说着，摇晃着一个纸板箱。 “我姐姐露西亚从布宜诺斯艾利斯给我寄来了笔。” “耶！”小鸟叫道。埃伯林太太举着不同的品种和不同的颜色。 “我姐姐开了一家美术用品店。 这些是她散落的一些不匹配的衣服。 这是对你目前为止在语言艺术方面做得很好的一份礼物

projects. Just reach on in there and pick which pen you'd like." Birdie picked a cyan blue one. I picked a fuchsia pink one. Then we used the pens to write haiku about our science projects. A haiku is a type of Japanese poetry that I love because it's so organized. The first line has five syllables, the second line seven, and the last line has five. "You know why I like haiku?" said Elijah. "Because they're short poems." "Don't you like poetry?" asked Phoenix. "I do, but I like it even better when it's short," he said. "It definitely makes it faster to write," I added as I finished my own poem. Rube Goldberg Machine By Kate Crawford This cool machine is A chain reaction that shows Six types of science

项目。把手伸进去，挑你想要的那支笔。” 小鸟选了一个蓝绿色的。 我选了一个紫红色的。 然后我们用钢笔写关于我们科学项目的俳句。 俳句是我喜欢的一种日本诗歌，因为它很有条理。 第一行有五个音节，第二行有七个，最后一行有五个。 “你知道我为什么喜欢俳句吗？”以利亚说。 “因为它们是短诗。” “你不喜欢诗歌吗？”菲尼克斯问。 “我喜欢，但我更喜欢短头发，”他说。 “这绝对能让我写得更快，”我写完自己的诗后补充道。 这个很酷的机器是一个链式反应，它展示了六种科学
