An Interest Science Class
By Yiler Huang
We did an interesting experiment a few weeks ago, and I also learned something useful. In this experiment called Voltaic Battery, I learned that you can actually use some simple things like nails and fruits to produce electricity. Voltaic battery was found out by a scientist called Alessandro Voltaic. He found out that chemical reactions can produce power in some special situations, and he invented a type of battery named with his name, which is called Voltaic Pile.
The whole experiment was about making a battery, by using a piece of zinc and copper, wires, and some pieces of wet paper, Or fruits and a few nails. Every single group made with fruits or pieces of zinc and copper are part of the Voltaic pile, and it can produce more electricity if the battery has more piles of it. So we put them in a small box and poured some water on to make sure that electricities could travel inside of the pile. It works because the chemical reaction inside of the pile can produce some little electricity, but if they are connected together, the electricity will become stronger while it travels longer through the Voltaic battery.
The result of the experiment was that we use the fruit to make a LED light glow, and it did. I think it can even run a whole computer or an electrical car if we had enough fruits. This might be useless in my life, but it’s still fun to learn that there are so many ways to get electricity. It's still a good experiment even though that it's sort of useless.
If we have a chance to try this experiment again, I would like to increase the amount of fruits we have. Because when we were doing this experiment, the light ball glowed. But it's not very bright. So I think if we want to see the experiment is successful o not more easily, we should have more materials so that the result will be more easy to see.
In the end, I learned that it's important to learn how things works instead of just use them. Because you will know the thing you re using more if you actually learned how does that work. I think the importance of science class is to use the things we understand to explain how does everything in your life works. So, I hope that people can learn about more things in our life.
一節有趣的科學課
幾週前我們做了一個有趣的實驗，我也學到了一些有用的東西。在這個叫「伏打電池」的實驗中，我了解到你可以使用一些簡單的東西，比如釘子和水果來發電。伏打電池是由一個叫「亞歷山德羅伏打」的科學家發現的。他發現化學反應在某些特殊情況下可以產生電，於是發明了一種以他的名字命名的電池：伏打電池堆。
整個實驗是關於製造電池，使用一塊鋅和銅、電線和一些紙，或者水果和一些釘子。用水果或鋅和銅片製成的每一組都是伏打電池的一部分，如果電池有更多的電池堆，它可以產生更多的電力。所以我們把它們放在一個小盒子裡，倒了一些水，以確保電力可以在電池內流動。它之所以起作用，是因為水果或金屬片內部的化學反應可以產生少量電力，但如果將它們連接在一起，電力在經過電池時會變得更強。
實驗的假設結果是我們可以用水果讓 LED 燈發光，而且我們成功了。如果我們有足夠的水果，我認為它甚至可以驅動整個電腦或電動車。這在我的生活中可能毫無用處，但知道有這麼多獲取電力的方法仍然很有趣。這依舊是一個很好的實驗，即使它有點無用。
如果我們有機會再做一次這個實驗，我想增加我們的水果數量。因為當我們做這個實驗的時候，燈泡會發光。但它不是很亮。所以我認為如果我們想更明顯地看到看到實驗有沒有成功，我們應該有更多的材料，這樣結果才會更明顯。
最後，我了解到了解事物的工作原理而不是僅僅使用它們很重要。因為如果你真正了解了它是如何運作的，你會更多地了解你正在使用的東西。我認為科學課的重要性在於用我們所理解的東西來解釋你生活中的一切是如何運作的。所以，我希望人們可以在我們的生活中了解更多的東西。
