(Science Class) - We can see....
Today we learned by the experiment and got the results, one is light another is about seeing through the object.
今天的自然探索<光源與視覺>的實驗,讓我們得知二個結論:
由於,光線行進遇到不同介質時, 會有部分的光線被反射回來~
Objects look different in light and in dark.
You can see more clearer in light than in dark
當我們在黑暗中,有"光"的直射後,將能清楚看出物體 (大家看見我了嗎?)
Now we took something to block in your front.
One opaque is in front of your eyes, you can't see clearly.
換上一個不透明的塑膠帶,在光的直射下,因為不足以讓光進入...當然我們也不能夠清楚看到對方囉!!
What can you see? 你看到什麼了嗎?
Tell eveyone, Is it clear or not? 告訴大家是否清楚呢?
That's why, no light shines through we can 't see clearly.
這也是今天我們對光源進行的對比結論囉~~~
Next , we see through transparent.
接著換利用透明的塑膠杯....
Because it's transparent. 因為它是透明的...光可以順利通過
Is it much clearer? 是不是比較清楚了呢?
Exactly!!!! 真的耶!!!
So light can pass through some materials and light rays bounce back, it's called reflection.
光的直線進行實驗....好有趣ㄋㄟ^_____^ 大家在家也可以玩玩看唷~~~
