21 Measuring Results

CHAPTER TWENTY-ONE Measuring Results Centimeter (noun). A unit of length. It's 1/100 of a meter and about 2/5 of an inch. It's part of the metric system, which is based on the power ten. Two, four, six, eight who do we appreciate—ten! IN THE LAB, I SEARCHED under the tables. Birdie crept into the room and knelt next to me. "Any luck?" she asked. "Nope. This is all I've found." I opened my hand to reveal an eraser, a bubble gum wrapper, and a piece of lint. I nodded over at Ms. Daly, who was rummaging through desk drawers. She looked up. "So far, I've found this." She held a thick black calculator with a large silver screen. "But it's a graphing calculator." "It will require way too many lemons," I moaned. "We probably can get your mom to open up the front office," said Ms. Daly. "Maybe there's a calculator in there that might work." I didn't like the idea of bothering my mom, but...

第二十一章测量结果厘米（名词）。 长度单位它是1/100米，也就是2/5英寸。 它是公制的一部分，公制是以10为单位的。 二，四，六，八我们该感谢谁——十！在实验室里，我在桌子下面找。 伯迪蹑手蹑脚地走进房间，跪在我身边。 “运气好吗？”她问。“不。 这就是我所发现的一切。”我张开手，露出一块橡皮、一块泡泡糖包装纸和一块纱布。 我朝戴利女士点了点头，她正在抽屉里翻找。 她抬起头来。“到目前为止，我找到了这个。” 她手里拿着一个又厚又黑的计算器，上面有一块很大的银屏。 “但它是一个图形计算器。” “这需要太多柠檬。”我抱怨道。 “我们或许可以让你妈妈打开前台，”她说。 戴利。“也许里面有个计算器可以用。” 我不想打扰我妈妈，但是…

"Tell her," whispered Birdie. "About the person sabotaging you." "I don't want to be a tattletale," I whispered back. "At this point, she should know. It's not like you're the one who loses stuff." She half smiled. "That would be me." I let out a breath. "You're right." I walked over to Ms. Daly and started to explain what really happened. Midway through as I explained the part about Kate is bad at science, I realized that Dr. Caroline was standing in the doorway. Dr. Caroline! I closed my mouth. "Keep going," Dr. Caroline said. "Don't let me stop you. I think it's great to be up-front and honest. And it really makes me sad that someone is completely misunderstanding the point of STEM Night. It's not about winning. It doesn't make you better to put someone down. And it certainly doesn't make your project better, if you make some else's project worse." Dr. Caroline dug her hands down in her lab coat pockets. "It's wrong, Kate," said Ms. Daly. "I'm also glad you said something." "I wish I could do something to help," said Dr. Caroline, her voice full of concern.

“告诉她，”小鸟低声说。 “关于那个破坏你的人。” “我不想做一个爱说闲话的人，”我低声回答。 “在这一点上，她应该知道。 又不是你丢了东西。” 她微微一笑。“那就是我。” 我呼了一口气。“你说得对。” 我走向戴利女士，开始向她解释到底发生了什么。 在我解释凯特不擅长科学的部分时，我意识到。 卡洛琳站在门口。 卡洛琳博士!我闭上了嘴。 “继续，”卡洛琳博士说。 “别让我阻止你。我认为坦率和诚实是件好事。 有人完全误解了STEM之夜的意义，这真的让我很难过。 这不是输赢的问题。贬低别人并不会让你变得更好。 如果你让别人的项目变得更糟，你的项目肯定不会变得更好。” 卡洛琳博士把手伸进白大褂口袋里。 “这是不对的，凯特。” 戴利。“我也很高兴你说了些什么。” “我希望我能帮上忙。” 卡罗琳，她的声音里充满了担忧。

That's when I told them about the fingerprints we found using the cocoa powder. Why we were definitely sure that it was someone else. "Because we tested them. Those prints weren't mine." "I wish we could identify the student from their fingerprints," said Dr. Caroline. "I think it's important that they learn from this." "I know how to catch the person," said Birdie. "I figured it out because of my ink chromatography experiment. All we would have to do is take the poems off the wall and test the four poems that used blue ink." "I think we can do that," said Ms. Daly. "I'll just check in with Mrs. Eberlin." I looked at Birdie. "Thank you," I whispered. "We haven't caught them yet," she said. "But we will!" After Ms. Daly received a text from Mrs. Eberlin with the go-ahead, Birdie took the four poems and with scissors carefully cut out a strip on the very bottom where Mrs. Eberlin had us write the date. The date was about a centimeter from the end of the strip. I like to measure in centimeters because that's how scientists measure stuff—using the metric system. Birdie hung the strips in the middle of four pencils. "I need four beakers."

然后我告诉他们我们在可可粉上发现的指纹。 为什么我们确定是别人干的。 “因为我们测试了他们。那些指纹不是我的。” “我希望我们能通过他们的指纹来识别学生。” 卡洛琳。“我认为他们从中吸取教训是很重要的。” “我知道怎么抓住那个人，”小鸟说。 “我是在我的墨水色谱实验中发现的。 我们所要做的就是把诗从墙上拿下来，测试四首用蓝墨水写的诗。” “我认为我们可以做到，”她说。 戴利。“我去问问埃伯林太太。” 我看着小鸟。“谢谢你。”我低声说。 “我们还没抓到他们，”她说。 “但我们会的！”戴利收到埃伯林夫人的同意短信后，伯迪拿起那四首诗，用剪刀在埃伯林夫人让我们写日期的最下面小心翼翼地剪下一条。 日期距离纸条的末端大约一厘米。 我喜欢用厘米来测量，因为科学家就是用公制来测量的。 伯迪把纸条挂在四支铅笔中间。 “我需要四个烧杯。”

"On it," said Ms. Daly, who popped back with four plastic beakers. "Ah," she said. "I think I see where you're going. Continue." She deposited the four beakers on the table. "Kate, can you fill the beakers with ten milliliters of water?" asked Birdie. "The water is our solvent." "On it," I said, running to the science lab to grab a graduated cylinder. I sprinted back to the classroom before carefully filling up the beakers. I set them on the table in front of Birdie. She placed one pencil across each of the four beakers. The bottom of the strip just touched the water. "See, I'm going to let the ink get wet just like I did in my science project." We watched in amazement as the ink separated. It took about five minutes. "The color patterns are all different," she said. "Let's compare them to the patterns made from the Kate is bad at science test strip." We all stared. We had a match.

“这就去，”戴利说着拿了四个塑料烧杯回来。 “啊，”她说。“我想我明白你的意思了。 继续比赛。”她把四个烧杯放在桌子上。 “凯特，你能把烧杯装满十毫升水吗？”小鸟问。 “水是我们的溶剂。” “这就去，”我边说边跑到科学实验室去拿一个刻度圆筒。 我飞快地跑回教室，小心翼翼地把烧杯灌满。 我把它们放在小鸟面前的桌子上。 她在四个烧杯上各放了一支铅笔。 条的底部刚好接触到水。 “看，我要把墨水弄湿，就像我在科学项目中做的那样。” 我们惊奇地看着墨水分开。 大约花了五分钟。 “颜色图案都不一样，”她说。 “让我们把它们和凯特不擅长科学测试的试纸做的图案进行比较。” 我们都目瞪口呆。我们有一场比赛。
