learning Chinese

Some people think that Chinese learning is very boring, but there is always fun in the boring.

"Ling Ling Ling" was in class, and the teacher said to us: "Do you want to do the experiment?" "Yes." The students answered unanimously. The teacher took out an egg from a bag and carefully put the egg along the wall of the cup. The naughty baby plopped into the water like a diver, and fell asleep comfortably under the water, as if he hadn't slept for ten years. The classmates opened their eyes wide, looking at the egg that did not float, a little disappointed.

The teacher put some salt into the water again, and saw the salt falling to the bottom like snowflakes. The teacher picked up the stick and quickly stirred it in the water, and the egg also jumped up into the water ballet.

The salt slowly melted, but the baby egg seemed a little reluctant to leave the warm bed. She hesitated, wanted to continue sleeping, and then thought of looking outside at this beautiful world, it went up and down. The teacher carefully sprinkled a little bit of salt on the body of the egg, as if helping him with shower gel. It was really fun! You see, he was poking his head outside from time to time! Finally, these situations are After some changes, I saw the egg floating from the bottom of the cup to the middle of the cup like a big drunk fat man. Before this guy stabilized, the teacher had already sprinkled a lot of salt into the water. This is good, the egg swayed like a drunk, coming out of the water, revealing its pointed head. The mood of the students also became excited and excited. Someone also called: "The egg is floating..."

The teacher stretched out his finger and pressed the naughty egg, and saw the egg bouncing up and down, sinking to the bottom of the water, and then floating again, like dancing hip-hop, or twisting yangko. It’s so funny! Put it in the water and stir gently, and the baby egg dances happily in a circle around the spoon.

Why did the eggs float? At this time, the teacher said: "Salt and water have buoyancy and density. After the salt is dissolved in the water, it can increase the buoyancy of the water, so the eggs can surface and dance in the water. "At this time, we suddenly realized that a little egg hides such a big mystery. It seems that as long as we observe carefully and think carefully, we can discover more scientific mysteries and feel that science has brought us a lot of fun!

There is science in life, and science is also in life. Being a caring person in life, you will discover more and gain unlimited knowledge
