Watch the 300-word composition of Ayang primary school science and technology flow officer

This afternoon, the teacher will take us to the Mobile Science and Technology Museum in Dongyue Village. Everyone cheered as soon as we heard the news. We walked to the Science and Technology Museum with great expectation.

After a long walk, I finally arrived at the Mobile Science and Technology Museum. Looking at the outline of the science and technology museum from a distance, everyone shouted. When we walked to the door, the teacher had just finished the tips for matters needing attention and said, "Students can visit by themselves", and everyone rushed into the Science and Technology Museum. When I entered the gate, the first thing I saw was a lively scene, which immediately infected me: Wow! So many people! The bustling crowd and the dazzling array of scientific and technological exhibits made me at a loss and didn't know where to start. After standing for a while, I came to the laser harp, which made a beautiful jingle. I think it's novel, so I'm waiting to try this wonderful instrument in the back. There are too many people. It's my turn. I nodded with anxiety and curiosity, and I was a little skeptical. However, when the finger falls, the harp makes a pleasant sound, which is so funny that I feel incredible. I tried to order it again at once, but this time I was not so upset. Like the first time, the sweet voice came out with the movement of my fingers, and I couldn't help laughing. I quickly ordered several times in succession, which was great. A string of voices came out, haha, it was wonderful. At this time, some students behind me can't wait to urge me, and they want to try it quickly. But I still can't bear to leave. I tried to click a few times and the sound came out again. Finally, I reluctantly left the laser harp, thinking: Oh, no, I just forgot to play, didn't read the explanation above, and forgot to see the principle of the laser harp. However, there are too many people waiting in line at the back, which I can't understand carefully. When I visit the next exhibition, I must also pay attention to this principle.

I gained a little experience through my first participation. I didn't visit blindly, but stood outside the crowd first to see which places were less crowded and which booths attracted me the most, and then observed selectively. This is both time-saving and effective. Through some observation, I found that there were many people waiting in line at the gate of Universal Cinema. Curious, I ran to the students waiting to come out and asked them what was going on inside. As the saying goes, "Know yourself and yourself", haha. After waiting for a while, a group of people came out of the cinema. I quickly went up and asked a female classmate, "Is it fun? That's funny, very interesting! I said "thank you", and then I went to "investigate" several classmates. The answers were all the same, so I quickly went to the back to queue up. When I was waiting in line, I saw Yang Meijun in my class. There are so many people that my legs are sore. Finally, it was our turn to go in. I hesitated at the door, because I was a little nervous when I saw it was dark through the crack of the door, but there was no room for consideration, so I followed the crowd in. It's dark inside, and the performance has already started. Wow! What a vast starry sky, it turns out that this is a display of starry sky, which is very three-dimensional and realistic. All the planets run around us, around us, as if we were a planet in this starry sky, flying around the sun. This feeling of being in space is very wonderful. When I was in a trance, suddenly a planet flew towards me, and I couldn't help it. " Shouted loudly and held Yang Meijun's arm tightly. This also scared her. Ha ha ha, so this is a 3d effect. In this cinema, the moon, the sun, Mars, etc. Usually out of reach, it seems within reach. In this magical space
