Learn composition everywhere (24 solar terms)

Since I was sensible, there have been many interesting things like the stars in the sky: learning to swim, skating, collecting specimens and blowing bubbles? I think playing with water is the most interesting thing.

One day last summer vacation, my uncle sent me the crucian carp he caught, and my mother-in-law kept these little guys in the pool. Growing up, I always liked to tease them whenever I had time. Once I played with fish with a soap box in the pool. I found a box floating on the water by accident, and I suddenly got excited. What can float on the water except the box? I also found foam blocks, scissors, magnets, building blocks, pieces of paper, table tennis balls and screws? As soon as Yi put these things into the pool, I found that scissors, magnets and screws all sank to the bottom of the water, while table tennis, foam, wood blocks and paper floated on the water. I was confused at the time. I was curious, so I asked my mother-in-law, who didn't tell me, and asked me to check the information. Finally, I found the complete works of China's children's encyclopedia-Light of Science. It turns out that foam blocks and table tennis balls are lighter than water, so they float on the water surface, while magnets, scissors and screws are heavier than water and naturally sink to the bottom of the water. At that time, I just thought it was interesting to tell my mother-in-law the result, just like Columbus discovered the new continent. My mother-in-law smiled and said to me, "Water has buoyancy. When jiaozi sinks, the floating of cooked jiaozi is also related to the buoyancy of water. "

I find this interesting and fresh in my memory because I have gained knowledge through playing and learned that life is full of knowledge. As long as we explore with our heart, we will find something.
