Fortune teller's eggs can dance _ tell fortune with eggs

In real life or work and study, everyone has written a composition, so you must be familiar with all kinds of compositions. Composition is a style composed of words, which expresses a theme through language organization after people's ideological consideration. What is the composition you have seen? The following is my carefully arranged dance egg composition, hoping to help everyone.

On Friday morning, we did an experiment of jumping eggs.

We have prepared a glass of water, a bag of salt, a transparent glass and a raw egg. I put the egg into the water first, and the egg lay firmly at the bottom of the cup, motionless. I asked strangely, "Why don't eggs dance?" The teacher said that another important guest had not come. I said, "Is that Mr. Salter?" The teacher nodded. Then I poured three spoonfuls of salt into the water Salt is as white as snow, but water is not so clear. I asked the teacher why he stirred, and the teacher said that stirring can speed up the dissolution. I saw the egg shook with chopsticks, but the water did not move, and the egg did not move, like a lazy girl.

Then we put three spoonfuls of salt into the water. Continue to stir with chopsticks, and the eggs magically float upwards, like a curious child who wants to see the outside world. I pressed it gently with my hand and the egg floated up and down like a tumbler. I said happily, "Eggs can dance."

I asked the teacher why. The teacher said that because salt melts, the density of salt water is greater than that of clear water. The buoyancy is also great, so the eggs float. Today I know the secret of salt. Science is amazing!

Dancing Egg Composition 2 Why do eggs dance? Are you curious too? Come with me if you want to know.

Today, the teacher led us to do an experiment. The name of the experiment is "Dancing Egg". The teacher prepared the materials needed for the experiment: three eggs, a basin of water, a bag of salt and a stirring stick. The experiment began. The teacher put an egg in the basin and heard a bang. The egg sank directly to the bottom of the water, like a child sleeping in the water. At this time, the teacher added a little salt to the basin, but the egg still slept at the bottom of the water and added a little salt. I saw the egg stand up slowly and sway from side to side like a tumbler. Finally, the teacher added a few handfuls of salt to the basin, and then the egg slowly poked its little head out of the water. We pressed the eggs into the water one by one with a stirring stick. As soon as the egg is released from the pressure of the stirring rod, it immediately floats and spins, just like a ballet dancer dancing. It's amazing!

Later, the teacher's explanation made me understand why eggs dance. It turns out that the density of eggs is less than that of salt water, so that eggs will float, as we just saw.

Teacher Zhao's comment: Very good. I learned about density through my own experiments. Keep trying!

Today I'm going to do an experiment with you, called Jumping Eggs.

Required materials: an egg cup, a raw egg, a small spoon and 3 spoons of practical salt.

First, connect the cup to two-thirds of the tap water. Then, add a spoonful of edible salt and stir with a spoon to dissolve the salt evenly in the cup. Finally, gently put the egg into the cup and let it stick to the bottom of the cup. When you release your hand, you will find that the egg does not sink to the bottom of the cup, but slowly floats upward, but has not surfaced yet. Finally, put the remaining 2 spoonfuls of salt into the water cup, while stirring, so that the salt is completely dissolved in the water, and be careful not to break the eggs. When 2 spoonfuls of salt are completely dissolved in the water glass, you will find a more amazing phenomenon: the eggs have surfaced! If you press the egg to the bottom of the glass with your fingers, after you release your hand, the egg will stagger to the surface again like dancing.

The secret of egg dancing mainly lies in salt. After adding salt to clean water, the density of salt water is greater than that of clean water, so the buoyancy will become greater. When it reaches a certain solubility, the egg will surface.

There are still many mysteries in science, just waiting for us to explore!
