今天學校的科學功課，是要看一部短頻回答問題。第一題，what physical property can help you to classify matter？弟弟看了幾遍摸不着頭緒，説是 by looking at it。媽媽舉例說 physical property 有點類似 physical apperance，例如媽媽的 physical appearance，你可以說媽媽的眼睛大大的，頭髮黑色的，頭髮長長的，胖胖的，高高的之類的。弟弟仍舊 by looking at it。媽媽再舉例，說外面的樹上有綠色的葉子之類的，他還是聼不進去，仍說：“對呀！就是 by looking at it，就是它的 Physical property！”眼看他都不理解，又快發脾氣了。媽媽問說：“那如果一個瞎子來問你，草莓長怎麽樣？你跟他說 by looking at it？”弟弟似乎理解了，收拾起快爆炸的情緒。媽媽畫了顆草莓，請他幫忙敘述他能夠描述的，例如紅色的外表，綠色的葉子，很多幼小的種子，輕輕的等等。終於有所領悟了。
