EP.15 伸縮自如的日子

from 巴迪日記 · host Kuwacha & Nancylu

橋梁上的縫隙、溫度計裡的水銀、還有會「砰!」的一聲爆開的氣球,它們之間有什麼共通點呢?這一集,巴迪和兔兔在博物館探險時,發現了「熱脹冷縮」的祕密,認識固體、液體和氣體遇熱膨脹、遇冷收縮的奇妙變化! 小朋友,我們今天在旅程中看到好多和 熱脹冷縮 有關的例子。 在橋上,有伸縮縫控制鋼鐵遇熱變長、遇冷變短的現象; 在博物館裡,看到溫度計是液體因為溫度改變體積; 就連兔兔的氣球和熱氣球,也是加熱後膨脹、冷卻後收縮。 所以,不論是 固體、液體,還是氣體,都會隨著溫度改變而「變胖」或「變瘦」。 這就是科學裡的熱脹冷縮原理。 旅程過後的週末,兔兔遇到了一個小麻煩: 他把一個玻璃瓶的金屬蓋子轉得太緊,結果怎麼也打不開! 如果你是兔兔,會怎麼運用「熱脹冷縮」的知識,幫自己把瓶蓋打開呢? 巴迪兔兔要開學了,之後的故事會兩週更新一次,我們9/26再見 點及下方巴迪日記找答案吧: https://www.eagoar.com/pages/event-page-bubbypodcast-2025 鷹展官網: https://www.eagoar.com/ 鷹展官方LINE: https://lin.ee/weC6MzP 鷹展粉絲專頁: https://www.facebook.com/eagoar -- Hosting provided by SoundOn
