I love science

When I was a child, my father told me a story: a listed company in Shiyan City, Hubei Province, celebrated the event, a cannon sounded, fifteen red-billed acacia birds flew into the air, dancing, but when the sound of the ups and downs was heard, Acacia The birds have fallen to the ground and died. Why is that? Later, many experts did not explain this phenomenon, and finally found the answer with the joint efforts of biologists and physicists. The sound of the original ups and downs is a noise to the Acacia, which destroys the bird's nerve hub and is the direct killer of the bird's death. At that time, I planted the seeds of science in my mind, and I wanted to be a scientist when I grew up. As I grew older, I gradually learned that science is knowledge, that is, power.

Science can help people solve problems and change lives. When Edison was a child, his mother got an emergency and needed surgery immediately. However, the hospital was too far away from his home and he would delay the illness. The doctor decided to operate at their home. However, there was no electric light at the time, the indoor light was too dark, and the operation could not be carried out. Little Edison was in a hurry, got a few large mirrors, adjusted the angles to the lights, reflected the lights on the temporary operating table, and the operating table suddenly lit up. The doctor successfully completed the operation and Edison’s mother was saved. This is the power of science. Later, after his continuous efforts and exploration, Edison finally invented the electric light and brought light to mankind. When Edison died, people commemorated him and turned off the lights in the country to show their condolences. That night, even the torches that the Statue of Liberty held high were extinguished.

I am full of curiosity about science and want to work hard to become a small inventor. On a Sunday in the last semester, I went to the Newton Experimental Class with my brother Guo Zihan. This time I did the astrological instrument. The teacher explained the knowledge of many constellations with us, and then sent us the equipment. Then we started our own invention. First, a lot of small holes are made on a piece of paper according to the mark of the star map, and the star paper piece and the half piece of hard paper piece are glued together. Then, two dry batteries were fixed on a large foam plastic with double-sided tape, and the wires were soldered to the small bulb and the battery. Finally, install the small light bulb on the bottom of the paper cup, and stick the star drawing piece on the foam plastic with double-sided tape, so that the star imager is finished. After the completion, I demonstrated the results of my labor. When I saw the clear constellation pattern on the wall, I was stunned. I am very surprised and excited about this strange phenomenon. I have kept this little invention, and I have worked tirelessly to become a small inventor.

Science is a double-edged sword. Good people use him to benefit mankind. Evil people use it to destroy our homeland. I love science. I want to be a scientist, use science to serve people, make our lives better, and make the world more beautiful!
