What class are we going to have today? It's density! Do you know what density is? Simply put, it is the mass under the material unit. Those with high density will sink, while those with low density will float up~ Does it sound a bit difficult?
Experiment - Rainbow Cup to learn about density!
In the experiment, we used different liquids and food colorings, and created layers through the characteristics of different liquid densities. After the liquid is added, you can put the screw ,
sponge , jelly and bottle cap in order! During the experiment, the children will find that different densities cause different layers, and then form layers as beautiful as a rainbow~ Everyone has made their own rainbow cup, isn't it very interesting
今天要來上什麼課程呢？就是密度啦！
小朋友們知道密度是什麼嗎？簡單來說就是物質單位下的質量，密度高的會向下沉，而低的則會往上浮～聽起來是不是有點困難呢？沒關係，讓我們透過一個簡單的實驗-彩虹杯來了解密度！
在實驗中，我們使用不同的液體及食用色素，並且透過液體密度不同的特徵，來產生分層。在液體加入完成後，就可以將螺絲釘、海綿、果凍及瓶蓋依序放入啦！在實驗的過程中，小朋友們會發現不同的密度造成不同的分層，進而形成想彩虹一樣漂亮的分層啦~每個人都有製作獨屬於自己的彩虹杯，是不是很有趣呢？
