歡迎閱讀《週日科學版》!我們每週日都要為你介紹可以在家中進行的有趣科學實驗。你可以在《科學日誌》中 記錄自己做了哪些活動,這樣就可以將所學的紀錄下來,比較這些結果,也許還可以利用它們來設計新的實驗!先看一下《科學日誌》的點子再開始吧。展開實驗之前,記得要獲得大人許可喔!
This week we are going to explore the relationship between our senses and food, or more specifically, flavors. Make sure you wash your hands before this experiment!
