學習目標:知道磁力的存在以及強弱的分布,了解生活中哪些物品會受到磁力吸引,理解同性相斥異性相吸的原理,認知兩極必定同時存在。

說明

本原創內容中的活動旨在探索以下概念:


  • 活動1:有哪些物品會被磁鐵吸引?
主要概念:磁鐵僅作用於金屬製成的物體。


  • 活動2:磁鐵會怎麼移動?
主要概念 理解同性相斥異性相吸的原理。


  • 活動3:指北針會怎麼轉動?
主要概念:磁鐵靠近指北針會發生什麼?地球就像是一個巨大的磁鐵,有北磁極和南磁極。
  • 活動4:迴紋針會怎麼被磁鐵吸引?兩極和中性區。
主要概念:磁鐵的兩端磁力最強。中央部分磁力最弱。


  • 活動5:磁極會有什麼變化?
主要概念:如果將一塊磁鐵分成兩塊,則每塊仍將有一個北磁極和一個南磁極。 認知兩極必定同時存在。
