有趣的实验课英语日记带翻译

　　今天，我们上了一节非常有趣的'实验课。

　　Today, we had a very interesting experiment lesson.

　　我们组做的实验是”飞碟“。首先，将电键、两个电池盒和电动机按照图纸上所示的连接起来。其次，把四节电池分别放进两个电池盒里。然后，把扇叶安装到电动机上。最后，按住电键上的小铁片，按长时间后，突然松开，扇叶就会飞出去。

　　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.

　　通过这节实验课，我学到了扇叶在转动时，会形成向下的气流，气流就会把扇叶托起来，扇叶就会飞出去了。这真是一节有趣的实验课呀!

　　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!
