My newly discovered composition of 400 words is urgent, urgent, urgent, urgent! A little better.

Facts are stranger than novels. When we experience life, we often make some new discoveries, so that we can increase our knowledge and grow sturdily.

I saw this experiment on my homework this summer-

Add different amounts of salt to three cups containing the same water and eggs, and you will find that the eggs will stay in different positions in the cups.

Hey, what happened?

So, I went to ask my parents: "Mom and Dad, why are eggs with different salt content placed in different places?" My father said to me, "Try it yourself and you will know!" "

Gee, why didn't I think of that!

So I took out three cups, three eggs and salt.

Everything is ready, the experiment begins!

First, I put three eggs in the clear water in the cup. Look! Eggs are like a sleepy fat doll, dreaming a beautiful dream at the bottom of the cup.

I put a spoonful of salt in the first cup, and nothing changed except that the egg moved in the water for a while.

Then, I put two spoonfuls of salt in the second cup and the eggs began to move. Slowly, the eggs are suspended in the water.

Then, I put three spoonfuls of salt in the third cup, and the egg moved in the water for a while and then floated.

Do you know why?

It turns out that the density of water has changed after adding salt. When the density of salt water is greater than that of eggs, eggs will float, and when the density of salt water is equal to that of eggs, eggs will be suspended in water.

From this experiment, I understand a truth-

Actually, there are many mysteries in nature. As long as we pay attention to observation and be good at thinking, we will keep making new discoveries.
