有趣的實(shí)驗(yàn)課英語(yǔ)日記帶翻譯
今天，我們上了一節(jié)非常有趣的'實(shí)驗(yàn)課。
Today, we had a very interesting experiment lesson.
我們組做的實(shí)驗(yàn)是”飛碟“。首先，將電鍵、兩個(gè)電池盒和電動(dòng)機(jī)按照?qǐng)D紙上所示的連接起來(lái)。其次，把四節(jié)電池分別放進(jìn)兩個(gè)電池盒里。然后，把扇葉安裝到電動(dòng)機(jī)上。最后，按住電鍵上的小鐵片，按長(zhǎng)時(shí)間后，突然松開(kāi)，扇葉就會(huì)飛出去。
The experiment our group did was a flying saucer. First, connect the key, the two battery boxes and the motor as shown on the drawing. Secondly, put the four batteries into two battery boxes. Then, install the blades on the motor. Finally, press and hold the small iron piece on the key, press it for a long time, then suddenly release it, and the fan leaves will fly out.
通過(guò)這節(jié)實(shí)驗(yàn)課，我學(xué)到了扇葉在轉(zhuǎn)動(dòng)時(shí)，會(huì)形成向下的氣流，氣流就會(huì)把扇葉托起來(lái)，扇葉就會(huì)飛出去了。這真是一節(jié)有趣的實(shí)驗(yàn)課呀!
Through this experiment lesson, I learned that when the fan blade rotates, it will form a downward air flow, and the air flow will lift the fan blade, and the fan blade will fly out. This is really an interesting experiment class!
