4 Bouncing Ideas

CHAPTER FOUR Bouncing Ideas Science demonstration (noun). Introducing or explaining a principle of science through a visual example so others can see it firsthand. Like you might create an eruption in a papier-maché volcano with vinegar and baking soda to demonstrate an acid-base chemical reaction. I FLIPPED THROUGH A CHEMISTRY BOOK, searching for the perfect experiment or demo. "Are you guys having any luck finding a project?" "Not yet." Birdie thumbed through The Big Book of Totally Awesome Science Experiments, which was propped on her lap. Right after the assembly, Birdie and I had grabbed a bunch of science books from the school library to look for the perfect experiments together. Elijah and Memito had been hanging out at Elijah's house after school but had come over when they saw me and Birdie on my back patio. Elijah's yard is right next to mine so it's easy for him to hop over the chain-link fence. Now we were all sprawled on lawn chairs in my backyard. "I don't need luck," said Memito. "I've got my project all figured out. I'm going to test different

第四章跳跃思想科学论证（名词）。 通过一个直观的例子来介绍或解释一个科学原理，使其他人可以直接看到它。 就像你可能会用醋和小苏打在纸制火山上制造一个喷发来展示酸碱化学反应。 我翻阅一本化学书，寻找完美的实验或演示。 “你们找到项目了吗？”“还没有。” 伯蒂翻阅着放在她腿上的《超级棒的科学实验大书》。 集会结束后，我和伯迪从学校图书馆拿了一堆科学书籍，一起寻找完美的实验。 放学后，以利亚和梅托一直在以利亚家玩，但当他们看到我和小鸟在我家后院时，他们就过来了。 以利亚的院子就在我的院子旁边，所以他很容易跳过铁丝网。 现在我们都躺在我家后院的草坪椅上。 “我不需要运气，”梅托说。 “我已经把我的项目都想好了。 我要进行不同的测试

ways to dry mango and figure out which method tastes the best." He licked his lips. "I'm coming over to your house, so I can be a taste tester," said Elijah. "And celebrate me coming in first." Memito rubbed his hands together. "I'm going to use the prize money to start a cooking club." Elijah tapped on a tree stump. "Bet you can't guess what I'm going to do. Oops, sorry—I mean make an inference." He grinned. "Something with drumming obviously," I said. "Give that girl a pair of drumsticks," said Elijah. "I'm going to use different sticks on my drums and figure out which one creates the best sound quality. And since I'm going to win, I'll use the money to start a battle of the bands." Elijah elbowed me. "What's your experiment, Kate? I bet you already have yours all typed and printed out already." "Actually," I said, "I haven't figured it out yet. The problem is, there are just so many things I'm curious about." I peered up at the sky. "Like why is it blue up there? I'm not sure, but I have ideas. I know it has something to do with chemistry—all the particles and gases in the air." I pointed to a maple leaf that was bright red. "Why is that red? I know it's chemistry."

弄干芒果的方法，并找出哪种方法味道最好。” 他舔了舔嘴唇。以利亚说：“我要去你家，做个试吃员。” “庆祝我得了第一名。” 梅托搓了搓双手。 “我打算用奖金创办一个烹饪俱乐部。” 以利亚敲了敲树桩。 “我打赌你猜不到我要做什么。 哦，对不起——我是说做个推论。” 他咧嘴一笑。“显然是有鼓点的东西，”我说。 以利亚说：“给这女孩一对鸡腿吧。” “我要在我的鼓上使用不同的木棒，找出哪一种能产生最好的音质。 既然我要赢了，我就用这笔钱开始一场乐队大战。” 以利亚用肘撞我。“你的实验是什么，凯特？” 我敢打赌你已经把你的信都打好打印出来了。” “事实上，”我说，“我还没想明白。 问题是，我对很多事情都很好奇。” 我仰望天空。“比如为什么上面是蓝色的？” 我不确定，但我有想法。 我知道这和化学有关——和空气中的微粒和气体有关。” 我指着一片鲜红的枫叶。 “为什么是红色的？”我知道这是化学反应。”

"So basically, you come up with an experiment about anything that makes you curious," said Birdie. "Exactly!" I said. "It just has to be awesome for Dr. Caroline. I still have no clue what I would do with a thousand dollars though." I glanced over at Birdie, who had a mysterious smile on her face. "You figured out something," I said. "Yup." Birdie peered up from one of our science experiment books. "I want to use the prize money to paint a mural on the library wall." "And what about your project?" I asked. "Not sure." She started flipping through her book again. Then she came to a picture that made her gasp. "That's so pretty." It was a spread featuring colorful strips of paper towels hanging on a clothesline. "They look tie dyed. It's called an ink chromatography experiment. You get to separate colors." Her fingertips slowly brushed the image as if ink might somehow come off the page. "I think I've found my experiment!" "Still don't know what you want to do, Kate?" asked Elijah in a teasing voice. "No," I admitted. "Not yet." I pointed to our trampoline. "Let's stop talking. And go jumping." Everyone rushed over.

“所以基本上，你想出一个让你好奇的实验，”伯迪说。 “完全正确!”我说。“这对博士来说必须很棒。 卡洛琳。不过，我还是不知道该怎么用这1000美元。” 我瞥了伯迪一眼，她脸上带着神秘的微笑。 “你发现了一些东西，”我说。 “是的。”伯蒂从我们的一本科学实验书里探出头来。 “我想用奖金在图书馆的墙上画一幅壁画。” “那你的项目呢？”我问。 “不确定。”她又开始翻阅她的书。 接着，她看到一幅让她倒吸一口冷气的画。 “太漂亮了。”这是一种挂在晾衣绳上的彩色纸巾。 “它们看起来是扎染的。这叫做墨水色谱实验。 你可以把颜色分开。” 她的指尖慢慢地刷着图像，仿佛墨水不知何故会从书页上掉下来。 “我想我找到我的实验了！”“你还不知道你要做什么吗，凯特？”以利亚开玩笑地问。 “不，”我承认。“还没有。” 我指着我们的蹦床。 “我们别说话了。去跳吧。” 每个人都冲了过去。

Birdie grabbed my hand and we jumped together while Elijah and Memito started tossing as many balls as they could find onto the trampoline. It was like jumping in a hot air popcorn popper, only without the hot air. And without the kernels. After a big flip, I thought about how electrons move around an atom, sometimes in unpredictable ways just like the balls. Maybe I could make a miniature trampoline to demonstrate how electrons bopped around. I peered up at that blue atmosphere. "Maybe I could do a chromatography test of the sky," I said with a wink. "Ha ha," said Birdie. "I don't know," I said with a giant jump, "with chemistry anything is possible."

小鸟抓住我的手，我们一起跳了起来，以利亚和梅托开始尽可能多地把球扔到蹦床上。 这就像跳进一个热空气爆米花机，只是没有热空气。 没有果仁。在一次大翻转之后，我想到了电子是如何在原子周围运动的，有时就像球一样以不可预测的方式运动。 也许我可以做一个微型蹦床来演示电子是如何跳动的。 我抬头凝视着那蓝色的大气。 “也许我可以对天空做一个色谱测试，”我眨了眨眼睛说。 “哈哈，”小鸟说。“我不知道，”我猛地一跳说，“有了化学，一切皆有可能。”
