2026 雷比特自然小學:隱形的空間魔術師-磁鐵的穿牆祕密 (3年級)

from 雷比特生物空中講 · host 雷比特老師

人還沒踏入照顧前,對無常總是抽象。直到現實焦慮撲面而來,才被迫直面「存在與不存在」的重量。  🎧作家張曼娟:「照顧,是每個人必然會遇到的一段生命歷程」 點擊👉 https://fstry.pse.is/9ktpv6 —— 以上為 Firstory Podcast 廣告 —— 以生動活潑的方式,為年輕讀者揭開磁鐵與磁場的奧祕。從磁鐵名稱的起源出發,解釋磁極 N 與 S 的命名其實與地球磁場息息相關。透過磁力線的概念,深入淺出地說明「同極相斥、異極相吸」的物理規律,並介紹磁浮列車的實際應用。文中特別強調磁導率的原理,解釋為何磁力能穿透木頭或玻璃等物質,卻會被鐵板阻擋。最後,藉由簡單的居家科學實驗,鼓勵讀者觀察生活中無所不在的磁力應用。聽完後可以自主進行線上測驗,檢視學習成效喔~(需要登入gemini)測驗網址 https://share.gemini.google/nkIObAfTCJSE Powered by Firstory Hosting
