用水管隔空吸引鋁罐?│《科科學會了》把課本的「靜電(摩擦起電)」變有趣!-資源代表圖
靜電是什麼?靜電指的是電荷在物體表面不平衡分佈所引起的現象,當兩個物體互相摩擦時,電子會從一個物體轉移到另一個物體上,這種因為電子轉移而產生的電荷現象,就稱為靜電。靜電不會像電流一樣流動,它是暫時停留在物體表面的電荷,直到遇到導體或接地後才會釋放。以日常生活中的例子來說,當我們用塑膠梳子梳頭髮時,會發現頭髮變得容易吸在臉上,這是因為梳頭的過程中,電子從頭髮轉移到梳子上,使頭髮和梳子帶靜電,與臉產生吸附現象。

【自然系列-物理 | 光學02】(視覺原理與針孔成像)海什木牢中十年磨一劍 -part2-資源代表圖
海什木看到書上出現牢外的石像,而石像透過小孔在書上的成像竟然是倒立的!由此現象的觀察以及對人類眼睛的研究,他認為人類看得見東西,是因為光照到東西後,反射到瞳孔,在眼睛內形成倒立成像。

【自然系列-物理 | 力學02】(伽利略與慣性) 原來是習慣的部分阿-資源代表圖
亞里斯多德認為,物體必須受力才能持續運動。但伽利略在斜面實驗中卻發現,若運動中的物體不受力的話就會維持運動狀態。於是伽利略提出了慣性--也就是「萬物有習慣維持原本運動狀態的性質」的說法。
