化学家凯特 · 3 The STEM Night Disater
CHAPTER THREE Tickled Pink Potassium iodide (noun). A white salt made up of crystals. It's used in photography and the medical field. It turns yellow because it reacts with the oxygen and carbon dioxide in the air. I guess then you could call it mellow yellow. THE SLIDE SHOWED A SCIENTIST in a hot pink lab coat, her arms raised in a champion salute. Her eyes shone behind pink goggles. For a moment, there was a stunned silence. I definitely recognized that lab coat. And those goggles. "Dr. Caroline!" I shrieked, popping out of my seat. Kids whispered and pointed at Dr. Caroline's picture. Others stood up and cheered. And I was cheering the loudest. Dr. Caroline is my favorite scientist on YouTube. She does all of these really cool demos. My favorite is how she makes puking pumpkins
第三章痒粉碘化钾(名词)。 一种由晶体组成的白色盐。 它被用于摄影和医疗领域。 它变成黄色是因为它与空气中的氧气和二氧化碳发生反应。 我猜你可以称之为醇黄。 这张幻灯片展示了一位身穿粉色实验室大褂的科学家,她举起双臂,做了一个冠军式的敬礼。 她的眼睛在粉红色的护目镜后面闪闪发光。 一时间,大家鸦雀无声。 我肯定认出了那件实验服。 还有护目镜。“卡洛琳博士!”我尖叫着,从座位上跳了起来。 孩子们小声说着,指指点点。 卡洛琳的照片。其他人站起来欢呼。 我是最大声欢呼的人。 卡洛琳博士是我在YouTube上最喜欢的科学家。 她做了很多很酷的小样。 我最喜欢的是她做的呕吐南瓜
using a solution of hydrogen peroxide and dish soap, just like we did with Ms. Daly at the Fall Festival this year. I learn something new every time I watch Dr. Caroline. With the puking pumpkins, I learned about catalysts, things that speed up a chemical reaction. In this case, the catalyst was potassium iodide. So cool! I've watched all of the episodes on her channel at least a dozen times. Okay, sometimes more. I've pretty much memorized them. I'm pretty much her number one fan. Suddenly, my mom headed back to the microphone with a really wide smile. "I have some wonderful news," she trilled. Hard to believe there could be anything more after this. "Our school has won a special community grant, which is allowing us to fly Dr. Caroline here to judge the science projects and get you guys all fired up about science," said Mom. I turned to Birdie and she turned to me. We both mouthed "no way" at the same time. "And the best part," continued Mom. "The winner of the competition will get a thousand dollars to do something special for the school. Second place will get five hundred dollars, and
使用双氧水和洗洁精的溶液,就像我们对。 在今年的秋季节日。 每次看Dr。 卡洛琳。通过呕吐的南瓜,我了解了催化剂,加速化学反应的东西。 在这种情况下,催化剂是碘化钾。 太酷了!我在她的频道上看了至少十几遍。 好吧,有时候更多。我几乎都记住了。 我是她的头号粉丝。 突然,我妈妈带着灿烂的笑容回到麦克风前。 “我有一些好消息,”她颤音地说。 很难相信在这之后还会发生什么。 “我们学校赢得了一项特殊的社区拨款,这使我们能够飞博士。 卡洛琳来评判科学项目,让你们对科学充满热情,”妈妈说。 我转向伯迪,她也转向我。 我们俩同时用嘴说“不可能”。 “最重要的是,”妈妈继续说。 “比赛的获胜者将得到一千美元,为学校做一些特别的事情。 第二名可以得到五百美元,还有
third place will get two hundred and fifty dollars. So our whole school community will benefit from this grant, not just because we get to meet Dr. Caroline and have our very first STEM Night, but because three of you will get to choose a special way to make our school better for years to come!" I jumped up and down like I was on a trampoline. The clapping in the auditorium grew louder. STEM Night. A science competition AND I was going to meet Dr. Caroline live-and-in-person. Sure, I might have lost Jeremy's dumb bet. But that was okay. Because from my point of view, I had already won something much better than any bet.
第三名将得到250美元。 所以我们整个学校社区都将从这笔拨款中受益,不仅仅是因为我们能见到。 卡罗琳和我们的第一个STEM之夜,但因为你们三个人将选择一种特殊的方式,让我们的学校在未来的岁月里变得更好!”我像在蹦床上一样跳上跳下。 礼堂里的掌声越来越响。 茎的夜晚。一场科学竞赛,我要去见布朗博士。 卡洛琳的世界去,与人。 当然,我可能输掉了杰里米的愚蠢赌注。 但没关系。因为从我的角度来看,我已经赢得了比任何赌注都好的东西。
