A fun Science Experiment in Class 2019. 01.10
考試完，老師讓我們做有關溶解的實驗，就是結晶。首先將明礬倒入熱水中，攪拌到看得到明礬的沉殿物，然後將毛根折出我們自己想要的形狀，再將毛根放入熱水裡，然後就是等待了，希望明天實驗可以成功。
After the final examination, we did a very fun science
experiment concerning the ‘dissolving of substances.' In the beginning, we put potassium alum
into hot water and then stirred for a while. We saw some precipitant in
the bottom of the cup. Secondly, we folded the wool stick into different shapes
that we loved. Then, put the wool stick into hot water. We will have to wait a
long time to see what is going on. I hope our experiment will be successful!
