My new discovery composition 1 As soon as I saw the topic "My new discovery", I immediately recalled an incident that happened in my hometown this year.
That morning, I borrowed a toothbrush, brushed my teeth and flew back to my grandmother's house. As soon as I entered grandma's yard, I heard a hen call "Goo Goo Da! Hey! " It turned out that a hen had laid an egg and was crowing gloriously. I heard this, and immediately ran to the front of the chicken nest, picked up the eggs, ran into the house, and put the eggs in the basin where there were already several eggs. I am very proud, thinking that I have done a great deed for my grandmother. At this time, grandma saw it and quickly said to me, "Alas! You are really! Mix the eggs I just made with the raw eggs! "
I was dumbfounded. After a while, I had to use my brain and start thinking about the solution to the problem. However, I still can't remember what I was thinking. I glanced at the book, and suddenly, I had a brainwave and began to look it up. "hey!" I shouted excitedly, "I know what to do!" " "Then I started the experiment: I started to spin eggs, which were cooked quickly and raw slowly.
Sure enough, I separated the eggs at a very fast speed. Grandpa knew and praised me: "It's a good choice to look up books when you have difficulties!" " "
My newly discovered composition is two days in Tomb-Sweeping Day, and my family went to the mountains to sweep their ancestors' graves. We drove past Gui Jiang first, and I saw ripples on the water, and waves floated from time to time. How beautiful!
After a while, we reached the other side. Let's go straight ahead. I looked around and suddenly found that the mountains were all green. I found it first. That is a bamboo forest. Those bamboos are one after another, dense. The air is fresh, and it is refreshing to walk in. I was deeply attracted by the beautiful scenery. I don't know when my father asked me to go. It really makes me linger.
Then I found a piece of camellia oleifera and smelled a faint fragrance. The leaves of Camellia oleifera are green, piece by piece, and really beautiful.
Then, I saw a group of white pigeons lined up in the air. You can hear cuckoo calls from time to time. It seems to be singing a beautiful song. While listening to the "song", I walked forward for more than an hour and arrived at the cemetery. When I arrived at my ancestors' cemetery, I found several yellow birds singing in the tree. I walked over carefully and scared away the birds at once. It's really interesting.
I made a lot of discoveries today!
I still remember going to my grandfather's house to play last autumn and running into the yard to find a beetle crawling desperately. Its six legs are small and hairy, and its shell is hard, with a pair of wings inside. Its eyes are small, like a crack, and its belly is like a big ball.
I am curious. I watched it itch. I picked up a branch and tried to stir it gently, but it didn't move. I did it again, but it didn't move, like a wooden head.
I whispered, "It turned out to be a dead beetle. It's not interesting at all. I won't play. " I watch TV. Ten minutes later, I went to see the beetle again. It's still crawling. I turned it over and it stopped moving. I hid, it moved again, and finally it wanted to fly away, but I quickly caught it back. That's interesting. You will fight with me.
I went online to find out why the beetle didn't move. According to the internet, once the beetle meets the enemy, it will pretend to be dead, and then move when the enemy goes far away. I thought, so that's it. I must tell my parents. They will praise me and watch me carefully. Sure enough, my parents praised me. Later, I also found that beetles like to chew trees. They first peel off the old bark with their front legs, and then eat the tender bark inside.
I find that as long as I carefully observe the things around me, I can find many interesting phenomena.
My new discovery composition 4 Rodin once said: "Life is not a lack of beauty, but a lack of discovery." It's snowing. Have you ever touched the breath of spring? In spring, flowers are in full bloom, giving off a strong fragrance. Have you ever heard the chirping of insects? Life is a book, as long as you savor it carefully, you will find many new discoveries.
I remember last summer, I went to my grandmother's house for the summer vacation. Walking on the road, everything is green, just like laying a bright green carpet. The air is particularly fresh and refreshing. I came to a meadow next to my grandmother's house and played with my sister. I accidentally found a big hole in a vegetable leaf there, so I quickly took a stick and turned it over, which scared me! I saw an aphid munching on a vegetable leaf with relish, so I wanted to kick it to the west to save it trouble. Just when I wanted to do it, suddenly a group of ants "fell from the sky". I saw them dragging and carrying, and it took a lot of effort to transfer this aphid to a "safe zone". I am puzzled: Why do ants save aphids? I asked my mother puzzled. My mother smiled and said to me, "Because aphids often excrete a liquid called honey, ants like it very much, so ants should save aphids!" " It dawned on me after listening.
There is knowledge everywhere in life. As long as we are good at observation and diligent in thinking, we will constantly make new discoveries.
One hot afternoon, I was walking home after playing football. I was sweating profusely, and sweat ran down my face. Following the sweat, I looked back and saw a group of ants following my sweat. At this time, I had a question in my heart: Why do ants follow my sweat?
I thought hard as I walked. Maybe the ants are just curious to see what it is. Or maybe the ants think that following my sweat may bring them some benefits ... this is a mystery.
Just when I thought about it and couldn't come up with a satisfactory answer, I saw a man like me, sitting under a big tree in a sweat, surrounded by many ants. His sweat flowed like a stream, and swarms of ants surrounded him like this man, as if a desert wanderer who had been thirsty for a long time had found a sweet spring. At this time, I had a new idea: do ants like sweating very much? This answer seems to make me understand a little, but I still can't explain it scientifically, and I am always a little dissatisfied.
When I got home, I took a bath and opened my "100,000 Why" to find the answer. I find that ants have a very keen sense of smell. As soon as they smell coke sweat, they can't help following you. Because coke sweat will give off a strange taste or smell, which will arouse their curiosity. They like things like water and sugar very much, which forms a strange scene of "ants chasing sweat"
It turns out that as long as we use the window of human mind to explore and observe the secrets of nature, there will be new discoveries.
My newly discovered composition 6 It rained heavily for several days and finally cleared up. My brother and I went to play in the garden. These flowers are fragrant and beautiful.
When I was admiring a small purple flower, I saw something dark red. It looked like a small snake got into the wet soil, and I screamed with fear. The younger brother who was playing with mud heard this and ran over to have a look: "Oh, big sister, isn't this an earthworm?" What a fuss! "My brother happily dragged the earthworm out. The naughty brother fiddled with the earthworm with a small stone. Suddenly, my brother accidentally broke the earthworm's body. Looking at the twisted body of the earthworm, I quickly put two earthworms back into the soil with a branch.
A few days later, my brother and I went to play in the garden again. Remembering the earthworm that my brother "died" last time, I came to the soil where the earthworm was put. I found an earthworm with a black upper body and a light lower body. I clearly remember the last time my brother cut the earthworm's body into two parts, one with no tail and the other without head. Does earthworm have the function of regeneration? To prove my judgment, I decided to take an earthworm home.
I cut the earthworm into two parts and put it in a flowerpot with wet soil. After that, I will spray some water every three or four days to keep the soil moist. At first, the earthworm didn't change much, but the cut wound healed slowly, and there was still a little mucus on it. When the wound healed completely, earthworms began to grow. At first it grew two millimeters; A few days later, the earthworm grew another 5 mm; Then 7 mm, then 10 mm, the newly grown part is lighter in color, and the original part is darker in color, which is easy to see.
There are surprises everywhere in life. As long as I pay attention to observation and study carefully, I will discover the mystery of the world just like earthworms have the function of regeneration.
My new discovery composition 7 Grandpa left in winter and Miss Spring came quietly.
On Saturday, my parents took me to Yangcheng Lake to enjoy flowers. Pink peach blossoms, snow-white pear blossoms ... Just when I carefully observed the camellia, I found several snails gathered on a big and fragrant camellia. I gently pushed open the petals, thinking that the snail would fall. Unexpectedly, the snail seems to be firmly stuck by super glue. I picked up a snail and looked at it. I touched the leaves first to see if they were sticky, but they were smooth. I thought, "The leaves are very smooth, so the problem must be the snail itself!" " "
I also found that the hand that holds the snail is sticky. When I take a closer look, the mucus comes from the bottom of the snail. I turned the snail upside down and found a transparent liquid at the bottom, which felt sticky and had an unspeakable taste. I immediately made an experiment, asking my mother to give me the phone, put the snail on the screen of the phone, and then turned the phone upside down, but the snail didn't fall! It suddenly occurred to me that snails can stick to screens and leaves. What if there is oil? Can it still fall? I specially took the snail home, took out the olive oil, dripped it on the paper, and put the snail on it, yeah! The result is the same, still not falling.
I am very confused and go to Baidu with questions. Baidu mentioned that when a snail crawls, it cuts part of the mucus layer through the peristalsis of the pseudopoda, so that the viscosity of this small part of mucus will be reduced, which is convenient for the pseudopoda to move, but the viscosity of the rest is still high, which plays a fixed role, so that the snail will not slide down.
I finally understand why the snail won't fall. It turns out that small snails also have some scientific mysteries.
My New Discovery Composition 8 Last summer vacation in July, I came to my grandmother's house in the country to play excitedly. Grandma has a calf that just ate grass. Usually I like animals very much, so I offered to go to the mountains to herd cattle. As a result, I found a surprise Guess what this is?
The rising sun climbed into the window, and my friends and I hurried to the mountain. When we got to the mountain, all the cows were grazing on the hillside, and we were having fun. Unconsciously, the sun shed the last ray of afterglow, that is, the sun grandfather is going to wave goodbye to us. We took the cow home, and when I got home, grandma had cooked the meal. The summer night is beautiful. After dinner, I will go outside to catch fireflies.
When passing by the cowshed, I heard the sound of cows grazing inside. But when I looked carefully, there was no forage in the cowshed, but I did hear a sound! In order to find out, I went home and took a flashlight to shine in the cowshed, and found the calf leisurely closing its eyes and deftly wagging its tail to drive away mosquitoes. Looking closely again, I found that there was no forage in the fence, but the calf was chewing something with relish, which made me full of curiosity.
In order to solve this mystery, I went to Baidu to make relevant inquiries. It suddenly dawned on me that although the cow eats grass in its stomach during the day, it can't digest all the food at once. It will send the food back to its mouth and chew it again. This process is called rumination! Cattle, horses, sheep and camels all have this phenomenon.
What an interesting discovery! As long as we have a pair of eyes that are good at discovering, a pair of ears that are good at listening and a heart that dares to explore, we can discover the wonders of the world and life!
My new discovery composition 9 Listening to students say that the growth process of tadpoles is very interesting. I'm curious, so I want to have a try. In the evening, I asked my mother to catch a tadpole in the river and put it in a bottle full of water. I thought: this water is very clear, so I can observe it carefully and let tadpoles live a little freely. The tadpole caught by his mother is round, looks like a fish and has lateral organs.
A few days later, I went to see the tadpole, which was only one finger big. However, the tadpoles I saw this time have grown up a lot, swimming much faster and more flexible than before.
Two or three days later, I went to see the tadpoles again. This time, it opened my eyes. Little tadpoles have become abnormal tadpoles in such a short time. It seems strange, and I'm surprised.
Later, the deformed tadpole's stomach turned white, its tail disappeared, its body turned green and its head grew up.
A few days later, I continued to observe the lovely tadpoles. At this time, it was already a little frog that caught my eye. However, it is still too young to catch pests like an adult frog.
Another month passed, and I went to see if the little frog had grown into an adult frog. At first glance, the little frog grew into an adult frog, which was really beyond my expectation. It can swim and jump. However, the bottle was too small for the big frog to get out, so I had to smash it and let it out.
Through the growth process from tadpole to frog, I firmly believe that as long as everyone has a pair of eyes that are good at discovering, the world will become better!
My newly discovered composition 10 Last week, I went to the balcony window to change food for my budgerigar and found a very interesting thing.
My parrot is different from ordinary birds. My parrot has a small hook in its mouth, so it likes food with a shell. Every time I change food, I always throw away all the food, and I don't want to waste it, but I know I can't separate so many shells! While I was racking my brains, a gust of wind blew away most of the shells, and the rest were all edible. I want to know why all the empty shells have been blown away, and why the rest have not?
At this time, my mother came up to me with a big smile on her face, as if she had read my mind and said, "Do you know? The reason why the empty shell is blown away by the wind is because the shell is very light, and the wind can easily blow away very light things, so the rest is the unfinished food. " I nodded my head.
At this time, my mother pulled out a straw from her pocket like magic and taught me how to blow away the empty shell eaten by parrots. I blew so hard at first that I flew out with nothing to eat. Mom smiled and said, "Blow gently."
I learned this excellent method, and I am extremely happy! I won't waste parrot food next time. I want to thank this sudden wind, but also thank my mother for her inculcation, so that I can understand.
Through this important thing, I understand that there is learning everywhere in life. As long as you are good at observing and thinking seriously, you will find more interesting and meaningful phenomena.
My newly discovered composition 1 1 The world is really everywhere. Sometimes the solution to the problem will be wonderful, and often these secrets will be discovered by some people with a heart. Take me for example. Recently, I discovered a new principle, that is, the crushed table tennis will return to its original state when it meets hot water.
Last Sunday, my mother and I came to the gym to play table tennis. We just hit the ball, but it happened to me. I served a high ball, and my mother knocked it off the table, so I went to pick it up and accidentally smashed the table tennis. It's over, it's over. This is the "Double Happiness" three-star ball I bought with my pocket money accumulated for a week. It will take another week to buy another one. My mother came over and saw my embarrassment. She smiled and said, "Nothing, nothing, I can do it again." I said in despair, "How is that possible? They are all so flat, there is definitely no way! " Mom jokingly said, "Look! I'll change it back by magic at once. " Then he unscrewed the cup full of boiling water, put the ping-pong ball in it and said, "You can watch it later." I will be skeptical, but I must wait patiently. After about 5 minutes, my mother took the table tennis out of the cup. I was dumbfounded. The table tennis that has just been stepped on miraculously turned into a circle. "How is that possible?" I was surprised and asked, "What's the matter? How can a crushed ping-pong ball return to the garden? " Mom smiled and told me the reason. It turns out that air expands with heat and contracts with cold, and water is hot. When the air in the table tennis is heated and expanded, it will definitely change the table tennis back to its original shape.
This is the power of science!
Science is really everywhere. It is in life and learning. As long as you are good at observation and discovery, as long as you have a heart for discovery and be a conscientious person in life, science will often bring you unexpected surprises.
Let's act from now on! Starting from every little detail around us, starting from every little thing around us, let science benefit us!
My newly discovered composition 12 Today, we had an interesting science class. The teacher taught us how to observe the sepals, petals, stamens and pistils of rape flowers, and then know them separately. Accompanied by the bell, the teacher came into our classroom.
First, the teacher asked us to observe the rape flowers carefully, and then told her what we found. I looked at it carefully and raised my hand. Teacher invited Tan to answer: "Teacher, I found that I can distinguish the roots, stems, leaves, flowers, fruits and seeds of rape!" " "Hearing this, I suddenly realized. Then the teacher asked us to decompose rape flowers. I watched them carefully. Where are the yellow petals, green leaves and sepals? I raised my hand and asked the teacher, "Teacher, where are the sepals? "The teacher looked at our questioning expression and said," Sepals are small leaves that set off rape flowers! " "I looked at the rape flower in my hand and found a small green leaf next to the rape flower, which is a sepal. After decomposition, I found an interesting secret in the small pod next to the rape flower.
It turns out that this is the seed of rape. I squeezed this "small pod" carefully, but there was no mature rapeseed in it! Small, transparent and beautiful! I also saw some seeds of Xanthium sibiricum, which were spread by animals such as cattle and tigers.
Through today's study, I learned how to observe and decompose rape blossoms, and I also learned a lot about rape blossoms. I hope the next science class is still so interesting.
My newly discovered composition 13 My family has a big bathtub, and I like to take a bath in it in summer.
When I was taking a bath, I suddenly found a crack at the joint between the bathtub and the tile, and there were several small protruding things in the middle, which I didn't care. After four or five days, I looked at the cracks again, and the bulging things became bigger. It turned out to be a mushroom! I was just about to reach for it when I saw a bug crawling on the root of the mushroom. I was surprised and looked into the crack. God, there are at least 50 bugs in it! From ants to millipedes, you really have everything!
At this time, several question marks appeared in my mind: there is no soil in the crack, how can there be mushrooms? How can a few mushrooms attract so many bugs? I think and think, but I still can't figure it out. Although I am an animal lover, I respect the life of every animal, but it is really hard to think of these bugs crawling around in the bath, so I thought of a "coup": wash them away with water! I picked up the sprinkler, turned the water to the maximum, aimed at mushrooms and bugs, and said to myself, "Run, don't disturb my enjoyment!" " ".After a while, I saw that the bug was gone, and I proudly continued to take a bath, as if I saw the scene of the bug running away.
The next day, I happily went into the bathroom to take a bath. But when I got to the bathtub, I found more bugs. What's going on here? I quickly asked my father, and my father said, "That's because both mushrooms and bugs like wet environment, so the more you water them, the more bugs there are!" " "
After listening to it, I suddenly realized that I quickly found a pack of desiccant and sprayed it hard at the crack. The next day, the bug disappeared. How happy I am! You can take a shower again in the future!
