Everyone may discover some mystery of something, and there will be many experiences in the process of discovery, of course, even I, a person who does not like to discover, will discover the mystery of things, if you don't believe it, please listen carefully.

It was ...... on a hot and cool summer day

My sister and I were playing by the pond. Suddenly, a small red fish jumped out, a graceful dolphin-style diving action, with water droplets like a naughty child landed on the lotus leaf, rolled, turned over, and jumped up again, a flawless diving action was born.

I think that the lotus leaf must have been wet with water droplets, and the lotus leaf has no towel, so it is easy to catch a cold, and it can't take medicine. I dried it to give it a chance to sunbathe. So, I dragged the lotus leaves out of the pond with my own mopping floors.

Touch the lotus leaf with your hand, well, fluffy.

On Friday morning, all of our Year 4 went to the lecture hall for a science presentation.

This time, we were given a lecture by Professor Sun, the "father of science" from Taiwan, who was of medium height and had an amiable smile on his face, and we immediately felt that he was very kind.

During the two classes, Professor Sun did 5 or 6 experiments for us, including gravity test experiments, liquid nitrogen experiments, mug experiments, and so on. One of the most interesting is the liquid nitrogen experiment: Professor Sun put a balloon full of air into the liquid nitrogen at minus 196 degrees, and when he quickly took it out, the entire surface of the balloon formed a layer of ice, and everyone was stunned.

I didn't expect liquid nitrogen to have such great power, it's really dumbfounded.

I was very fortunate that in the last experiment, I was actually selected by Professor Sun to be on the stage to cooperate with him to complete the experiment. Another classmate and I were very excited that we were getting up close and personal with science! In order to protect us, Professor Sun also sent two of his assistants, "Brother Longlong" and "Brother Bibi", to protect us from being shot by "missiles".

I was very worried in my heart, if I was shot, then I would be sacrificing for science, too entangled! Just as I was thinking about Xun Hu Zheng so much, the launcher moved, and the "missile" passed by me, which was so thrilling that I broke out in a cold sweat. However, the poor teacher Chu who was filming was not so lucky, he was lucky to be shot by a "missile" if he didn't do anything, and everyone laughed, that scene was really funny.

The 80-minute speech ended with the reluctance of the students, this is the first time I have experienced the charm of science up close, and it is also the first time I have been shocked by the power, and I hope that Professor Sun will come to our second center next year to give us such an interesting and meaningful class!
