Go to Linyi Science and Technology Museum to learn composition.

I have long heard that Linyi Science and Technology Museum is very good, and I beg my mother to take me to the Science and Technology Museum to play. Today, this wish finally came true, and I really came to Linyi Science and Technology Museum.

When I walked into the gate of the Science and Technology Museum, I felt that I had gone deep into science and technology. All the secret knowledge revolves around me. I feel incredible about everything here. I couldn't help touching and watching there for a while.

We visited the Youth Science and Technology Exhibition on the second floor. My mother bought a ticket. After entering, I was attracted by the hourglass. It turns out that the hourglass is a stone funnel filled with sand. Then I blocked the bottom of the funnel with my fingers and threw the rope out. As the rope swings, the hourglass can make various patterns. Seeing that my classmates made many different patterns, I also did as usual.

After finishing this experiment, I saw a large group of students around a big screen. What are they doing? I also rushed over to join in the fun and took a closer look. The students are painting the trunk by hand on the big screen. I also put my hand on it and draw to the right. A thick trunk appeared on the screen at once, and the water immediately changed its direction when it touched the trunk. It's amazing! Why can hands draw on the screen? Why did the water change direction? At this time, the commentator's aunt came to tell us that the screen has infrared function, which can detect the living body, and only the living body can show traces. In life, electric doors, life detectors,,,,, are all based on the principle of infrared rays. At some point, the commentator's aunt picked up her mobile phone and gestured on the big screen, but there was no trunk. Although the mobile phone originally had infrared function, it turned out that,

The most interesting thing is the experiment of "relaxing the bodhi tree". This experiment makes bodhi trees grow into leaves by measuring people's heart rate. When your mood is completely relaxed, the bodhi tree will grow lush branches and leaves, and finally a rainbow will appear. If you don't relax, the leaves will slowly fall. I tried, but I can't completely relax. It seems that we should learn to adjust our mood and relax in the future. I believe that one day, I will let the bodhi tree grow lush branches and leaves and appear beautiful rainbows!

After visiting the Science and Technology Museum, I also mastered a lot of scientific principles and some scientific knowledge, including hourglass principle, infrared principle, electrical principle,,,, and these scientific principles can also be used in our lives. "Knowledge changes our destiny and technology changes our lives." Let's study hard, master more knowledge and study and explore the mysteries of science from now on. Believe it. Science is magical! If you don't believe me, experience it yourself!
