6th grade essay on science mythology 400 words

Science. One day, I was sitting on the sofa watching TV, and my father saw that I was bored, so he said, "Xingyue, do you know how to make two cups close together?" Let's do an experiment! I listened excitedly and said, "Okay! ”

The experiment began, Dad asked me to bring two glasses of the same size and a small piece of paper, and filled two of the cups with water, Dad first covered the piece of paper on one of the cups, pressed the piece of paper tightly with his hand, quickly turned the water upside down, and turned the water cup and the piece of paper upside down on the other cup, Dad said, "Remember, the mouth of the cup should be opposite." After the cup was stable, he gently pulled out the small piece of paper, and the cups stuck together, "Wow!

It's amazing" I exclaimed, and Dad laughed and said, "Let me show you how it works!" Although the two cups cannot be completely sealed together, the surface tension of the water itself fills the gap between the cups, and the effect of the outside atmospheric pressure will not spill the water!

Oh! So it dawned on me.

There is science everywhere in life, as long as you pay attention to observation, there will be new discoveries, just like we usually study in this truth, as long as we put in the effort, pay sweat, no matter how difficult the problem will be solved.

Mythology. Once upon a time, there was an ordinary woman, her hair was black and shiny, long, her hair was always draped around her waist, her eyebrows were curved like the moon, her eyes were like round grapes, her nose was small, she had a mouth like a cherry, she loved to wear beautiful dresses, and she was very beautiful! A beautiful woman, her name is Chang'e.

Chang'e is a very beautiful woman. Because Chang'e is beautiful, people like her very much, and children follow Chang'e and call her Sister Chang'e.

One day, a man came to the village, she looked sick and walked very badly, he walked to the door of Chang'e's house and fainted. In fact, that person is not sick, but I heard others say that Chang'e is very kind and caring, and the fairy wants to test Chang'e to see if Chang'e is kind or not, whether she is caring, if she is very kind and loving, let Chang'e also be a fairy. At this time, Chang'e heard the door ringing, opened the door and saw that it was a patient, Chang'e didn't know that person was a fairy, and couldn't wait to help the patient home, and asked a few doctors to see the patient, slowly, the patient's illness was cured, and after a few days, the patient said to Chang'e:

In fact, I am a fairy in the sky, I am not sick, but others say that you are very kind and loving, I want to test you, I will give you two elixirs, you eat it, you will fly to the sky and become a fairy. Chang'e ate the two elixirs and slowly flew into the sky.

After Chang'e flew into the sky, the people of the village missed him very much, and whenever the moon rose in the evening, the people of the village pointed to the moon and said, "Look, look, this is Chang'e's hotel, where our sister Chang'e lives." ”

There are many mythological stories about the origin of mankind. For example, Nuwa's creation of man and the creation of man in the Garden of Eden are all misinterpretations of human evolution. However, some people still firmly believe in this erroneous interpretation, why? Because they have a charismatic nature.

All the charm of the myth of human origin is that the myth itself is rich in imagination, which can make readers fantasize, detach from reality, and come to an illusory realm, which is easy to make people think about it. Both adults and children have a soft spot for this kind of article. Myths and stories are full of innocence, and they write about nothing.

In addition to reality, people can also enter another illusory world. Just like in "Nuwa Creates Man", it is written that Nuwa is a god with great powers, and she can also make people from the soil. As far as God is concerned, he has made a big mistake.

Are there really immortals in the world? No. But there is something in the article, and the magic is vast, and the non-existent is written, such an imagination is very boldly written.

Let's talk about making people out of the soil. All right? It's impossible, try it or not, it's nonsense.

But the author wrote it again, and people liked it because it wasn't real, and people liked the plot they liked more and more. Because there is enough space for everyone to give free rein to their imagination, unlike Xi'an, which can only be accepted by people and no miracles happen, but there are myths, otherwise why is it called 'God'.

That's the beauty of mythology. Are you becoming more and more fond of mythological stories?

Science, in fact, is everywhere. Ever since I was a child, I've loved to ask why.

Once, we went out to see the scenery together as a family, got into Dad's car and left. On the Banqing Youdou Road, I saw some people selling balloons, and at this time, a big question mark came to my mind: why can their balloons fly into the sky, but the carbon dioxide balloons we blow up can't?

We've played and watched it, and when I got home, I rushed into my room and pulled out "100,000 Whys." I entered the book with this question in mind. The book reads:

The balloon is oxygen, which is lighter than dioxonic carbon and lighter than oxygen in the air, and can fly upwards with the balloon. So their balloons can fly into the sky. Ha ha!

I've finally solved a mystery in my mind! I'm so happy!

There is another question, I still don't know the answer, this question may be unknown to many children and even parents: what exactly is a water elf? That's when I saw a question about the water sprites selling at the stall.

I know from the computer that the water fairy is an absorbent resin, which is generally mixed with starch and acrylonitrile, which is highly toxic. It seems that I won't be able to play water sprites in the future, but I have learned another knowledge.

In fact, there are many scientific problems around us, even a small melon seed, which is worth observing. When I grow up, I want to be a scientist.

Whether in school or in society, everyone is indispensable to come into contact with composition, which is a narrative method that expresses the meaning of a theme through words. So how do you write a good essay? The following is my collection of 600 words of my science experiment essay for your reference, I hope it can help friends in need.

During the summer vacation, my science teacher suggested that I do a science blog, and I asked my father, "Dad, the teacher asked me to do a science blog, what can I study?" Dad pointed to the two fish tanks in his office and said

You can look at my fish tank, do you see if the water in these two fish tanks is the same? "After a period of observation, I found that the water in the two fish tanks is indeed very different, and the water in the fish tank by the window is green and placed on a dark desk'The water in the tank is very clear and transparent. Dad also told me that if there is a lot of green algae growing in the water, the water will turn green, and green algae is a plant that is invisible to the naked eye.

After listening to my father's words, I guessed that since green algae is a plant, it must need light and nutrients to grow.

To prove my suspicions, I immediately started experimenting. I'll start by preparing a couple of large mineral water bottles, a pair of scissors, a couple of beakers, ....... Then I did two experiments, one experiment is to verify the effect of light on the growth of green algae, in this experiment the conditions that are changed are light, and the conditions that do not change are water, containers, placement positions, etc., after 10 days of observation, I found that the water with strong light turned green, and the water with weak light did not change significantly; Another experiment is to verify the effect of nutrients in water on the growth of green algae, in this experiment the conditions changed are the content of nutrients in the water, and the conditions that do not change are light, containers, placement positions, etc., after 10 days of observation, I found that the water with more nutrients turned green, and the water with less nutrients did not change.

The results of these two experiments were analyzed, and my guess was correct.

Knowing that the reason why the water in the fish tank turns green is light and nutrients, I want to make the green water in the fish tank clear again. The specific measure I take to control the light is to place the fish tank in a position where direct sunlight does not shine but there are enough scattered light holes (because the creatures in the tank need light, so the fish tank cannot be placed in a place without light). Specific measures to reduce nutrients are changing one-third of the water in the tank every week, filters working 24 hours a day, planting aquatic plants, controlling the number of aquatic animals, and adding nitrifying bacteria to the water.

After two cycles of observation, I found that the water became clearer and more transparent.

After this science blog activity, it not only enriched my summer life, but also taught me a lot of knowledge.

One night, I was cooking dinner for my mother, and she told me to unscrew the new soy sauce bottle, but I couldn't unscrew it.

I asked my mother, "Mom, why can't you unscrew the soy sauce bottle?" Can you unscrew it for me? ”

Mom said, "You go and use your brain, I won't help you twist it." ”

I was angry and said, "Mom, why don't you unscrew it for me?" Mom said

If you use your brain again, you just won't tell you. "I just have to think about it. I thought about it, I think it should be in the category of science.

So, I was unhappy and began to flip through the science books I had studied.

Suddenly, I turned to the lesson of heat expansion and cold contraction, and my heart was sweeter than eating honey, and I was happier than getting 100 points in the test. I said to myself, "I'll try this hot expansion and cold contraction!"

Usually, it is useless to watch your thermal expansion and contraction, and today I will try your ability to expand and contract. ”

With that, he went to the kitchen and tried it. Stir up some hot water first, soak the soy sauce bottle in hot water for five minutes, and then rinse it with cold water again, and it is easy to unscrew. I think:

Is there so much scientific knowledge hidden in human life? Is this scientific knowledge just waiting for us to dig into?

After this incident, I am grateful from the bottom of my heart that science has helped me improve and grow.

I love you, science.
