Observation diary 300-word encyclopedia of animals

Rule number one: cute puppy

Aunt Chen Bizheng has a lovely puppy named Sasha. Sasha's. Big leather coat? It is pure white, as pure as snow in winter; Of course, it has never snowed here. ) Sasha's eyes are black and bright. I don't know if it will light up after drinking; Sasha's tail? Follow? Behind Sasha's PP, I shook it. Although Sasha looks excellent, she is not excellent at all. Sasha's master is my aunt's cousin, and when she left, she told Sasha not to urinate anywhere and be obedient. Sasha also showed a very clever appearance before her master left. As soon as her master left, she began to run wild. First, I jumped up and down on the coffee table and broke a cup. The water in the cup spilled on the ground, and my aunt almost fell when she walked over. Then I peed in the hall, which made the whole space stink. Then he scared me under the sofa and tried to bite me. I'm afraid of dogs. Even the cute puppy scares me so much that I can't even move my feet on the sofa for fear that it will bite me. I swear I will never love dogs again in my life. Although I am afraid of dogs, my own dog will be safe. If I have a dog at home, I definitely don't want a dog like Sasha. What kind of dog do you like?

Chapter II: Giant salamander

My family just raised a giant salamander, which looks like a lizard. I put it in an ecological bottle and live with loach.

The front of giant salamander is dark brown, but the back of giant salamander is different. The colors on the back are scarlet, gray and brown. As fast as a brick, it filled the giant salamander's back. Giant salamander breathes with its lungs, but every once in a while, giant salamander will jump out of the water to breathe, and then quickly dive into the water. The giant salamander's limbs are short and fat, with 4 fingers on the forelimbs and 5 toes on the hind limbs, and no claws. Two fingers (toes) are different in length.

My baby fish is very lively. It just loves to crawl. It thinks its limbs can be compared with the sucker of Parthenocissus tricuspidata. Every time he climbs up, he always falls down. But it can climb out of the short bottle, and the reason why it can climb out is because of its tail. Giant salamander is easy to catch in the water because its skin is too slippery compared with loach. If you stay in a place without water for a long time, your skin will become sticky, but it won't stick when you return to the water.

Its lively and active personality has also caused trouble for itself. The morning after I bought the giant salamander, I went to the ecological bottle on the balcony to look for the giant salamander, and found that it was gone. I was in a hurry. I quickly told the news to my parents, and we all looked for giant salamander together. Finally, my father found it in a pile of marble. At that time, the giant salamander was dying. Father quickly picked it up by hand, put it in an ecological bottle and slapped it on the back with his fingers. After a while, the giant salamander woke up slowly, and then it was alive and kicking in the ecological bottle. Giant salamander's vitality is really strong!

Do you think my giant salamander is cute or not?

Chapter III: White Rabbit

The little white rabbit is really cute. Its hair is as white as snow, without a trace of noise. It feels soft and smooth, like soft brocade. The snow-white rabbit looks like a fluffy ball from a distance, with two long ears meekly attached to its back. Its eyes are as dazzling as sparkling rubies, especially its small and exquisite three-petal mouth, which is particularly eye-catching.

The rabbit is very picky about what it eats. He doesn't even bother to look at the common weeds in his mouth. But if he puts his favorite carrot on the edge of the cage, he will get a treasure. He will immediately bite down carrots and then pull them over and eat them. Bang bang bang bang? Crisp, a pair with relish. Although its mouth is small, it eats quickly, and it can finish three or four Chinese cabbage leaves in less than a minute. Whenever I caress its head after feeding, it always licks my hand with its tongue, as if silently expressing its gratitude.

One day when I came home from school, I saw my little cousin holding up the rabbit's ear, and its body was hanging in the air, making a cry of pain? Goo goo? Sounds, like calling for help, are like protests. I yelled at him. As soon as the little cousin let go, Bonnie ran away quickly and ran to a dark corner of the study, curled up with her ears pressed against her back. She watched every move around her warily, afraid of being hurt again. This posture lasted for a long time, so I ran back when I felt safe. What a clever rabbit!

Once I took the white rabbit out to play. He jumps happily on the grass from time to time. When you are tired, you squat down half-open and half-closed, looking like you are enjoying yourself. It turns out that he also likes the happiness brought by sports! Time to go home. I tried to catch it back in the cage, but it twitched its tail back and forth, as if to say? You can't catch me! ? What a naughty rabbit!

Because my parents are too busy, I have no time to take care of the rabbit's daily life. Finally, I put my beloved rabbit back into nature. I'll never forget when the little white rabbit looked back. His eyes are full of reluctance. I will miss the happy time we spent together.

Chapter Four: Observing Ants

Today, I will introduce an ordinary and great animal ant to you. Although ants are small, they have many qualities worth learning.

First of all, ants have dedication. Whenever there is a flood or fire, ants don't run around like other animals, but quickly curl up together and roll out of the sea of fire or water. In this way, even if the ants outside will be burned to death or drowned, the ants inside will be saved.

Secondly, ants have the spirit of unity and mutual assistance. Whenever an ant out foraging finds food, it doesn't eat alone like other animals. Instead, he asked his companion Qi Xin to work together to transport the food back to the nest and share it collectively.

Finally, ants have the function of forecasting the weather. Whenever it rains, ants will move to high places in droves or strengthen grain reserves. In this way, people will know that it is going to rain.

Therefore, we should protect ants and live in harmony with them.

Chapter five: tortoise observation diary

There is a little turtle in my home. It carries a big, hard shell on its back, as hard as a hard shield. I love it very much, and I gave it a nice name called Qingqing.

It is honest, never bothers others, and often climbs back to a corner after eating, motionless. One day, my father bought a piece of meat. I secretly cut off a small piece of lean meat with a knife and gently placed it in front of the little turtle with closed eyes. I wonder if it eats meat. Maybe the little turtle is a vegetarian because it didn't eat the lean meat I prepared for it.

On the third day, I squatted quietly and observed. For about ten minutes, I made a clear movement, then stretched out my neck, sniffed it one by one, then opened my eyes like mung beans, straightened my whole body, rowed my limbs, and ran to lean meat like a 100-meter sprint. Suddenly, I raised my vigilance and stopped.

On the fourth day, Qingqing climbed onto the lean meat. Clear and small, climb slowly. It picks it up slowly with its sharp claws first, and then eats it in its pants.

I think it's good to have a little turtle, because with this little turtle, my life has become very beautiful.

Article 6: My little hamster.

My family has a lively and lovely little hamster. That's brilliant.

It has a small round head. Two small black eyes are shining with dazzling light, like two black gems. A small pink nose with six slender beards. There are two small white, bright and sharp teeth in that small mouth. It can eat quickly, and it eats up five corn kernels in three or two times. Its back and head are covered with gray hairs, and there are a few white hairs on its stomach. The little paws on the limbs ran very fast and quickly ran from one side of the table to the other. It is very flexible!

It can be smart. One day, I gave it a melon seed to eat, and it took the melon seed and bit it open, so it could eat delicious melon seed meat.

I don't see it come out every morning. I thought: it can't help eating, can it? I think it should be active at night, right? Is that true or not? I want to do an experiment. So, I stood by the cage at night and waited for 30 minutes. The hamster looked left and right to make sure no one was there, and then came out for activities. It grinds its teeth hard for a while, grinding the cage to a crunchy sound, and then comes out to eat and wolfs it down. Ah! It turns out that hamster's schedule is completely different from ours!

I love the cuteness of hamsters and the cleverness of hamsters. I love my hamster!

Chapter 7: Snails

There is a new member in my family-snail. It's small and dark, so I call it snail? Gary the Snail? . It goes to bed early and gets up early every day. Every night, before I go to sleep, it is already in that small house? Sleep? Yes; In the morning, I got up in a hurry to visit it. I didn't expect it to have a thick shell on its back? Fitness? Yes

I remember once, the science teacher asked us to observe snails. I was so excited that I left without taking off my shoes? Little snail? Pick up the magnifying glass and start observing. I looked at my head first and found two pairs of tentacles, one long and one short. According to the teacher, the snail's long tentacles can sense the changes of the surrounding environment, and its eyes are on the long tentacles, but it can only be seen clearly in the dark. Short tentacles are used to find food. I carefully put some leaves in. Sure enough, it was interesting to see the snail touch it with its short tentacles three times. I looked at my abdomen again and turned the snail upside down. I saw something glistening, but I didn't see anything. I checked the books on popular science, only to know that snails have abdominal feet in their abdomen, which can help snails crawl. I followed the snail's tail again. At this time, I saw that there was mucus where it climbed. I quickly asked my mother where the mucus came from. What is its function? Mom said that mucus comes from the tail, and snails can make it faster by following the mucus. Putting down the magnifying glass, I went to the elementary school encyclopedia to see if I had more knowledge about snails.

Through observation, I know many secrets of snails. Students, as long as you carefully observe, you can find more secrets!

Chapter 8: Cricket

I caught some water hyacinths from Jinzhou Garden the other day and kept them at home.

I put him in a box to observe: they have black and yellow heads and strong hind legs, and they still carry it with them? Musical instrument? .

I put lentils in the box. I said on the internet that if you put food in it, you should leave immediately, or it won't eat food. But I verified that this statement is wrong. Before the lentil is finished, it is swallowed at once, revealing its pliers-like teeth, giving people a fierce feeling.

One day, I put two water hyacinths in a box, and then I touched the tentacles one by one with dog tail grass. Sure enough, the two men got into a fight, showing their pliers teeth. The fighting was particularly fierce. I didn't expect water hyacinth to spell like this. Soon, they stopped fighting, but they all gave a clear cry, called for a while and fought again. I checked the computer with doubt. I just realized that cricket still knows this.

Another day, I put in a female oil gourd to see if the female oil gourd is also a brave cricket. As soon as I put it in, the male oil gourd circled around the female oil gourd, as if to say, this is everyone's defensive posture. I saw that the female oil gourd jumped in front of a male oil gourd, as if she took a fancy to it, but the male oil gourd was ungrateful. Suddenly, she turned around and showed her pliers-like teeth, as if warning the female oil gourd not to come over. At this time, another male oil gourd, use it? Musical instrument? I used to play wonderful music. I'm attracted, mother oil gourd. Listen to my cousin. The male oil gourd is courting. ?

I love my cricket.

Chapter 9: Tadpoles

Today, my neighbor Liu Xing and I went to the well where he fed chickens and caught tadpoles. We catch tadpoles with vegetable baskets. I caught five tadpoles at a time. I'm so happy. After a while, Liu Xing told me that he also caught three or four. I think I caught more tadpoles than he did. I caught more and more tadpoles. At this time, Liu Xing came to have a look and accidentally poured out all my tadpoles. My heart panicked, and I couldn't catch them, because there was something slippery like oil on tadpoles. It took a lot of effort to catch three or four, and I suddenly felt like a deflated ball, full of unhappiness. So, we re-used the vegetable basket to catch tadpoles in the water, and caught one in a mineral water bottle filled with water. In this way, I caught more than 30 tadpoles and took them home for my mother to see. Sometimes tadpoles swim to the surface and sometimes sink to the bottom. Their movements are light, excited and happy. They seem to say, what a happy world! I don't know, they were put into bottles by others and lost their freedom. Since then, they have only a dead end, and their actions are getting slower and slower. I want to let them go, because tadpoles will catch pests when they grow up.

Chapter 10: Crickets

Autumn night, quietly lying in bed, listening to the ear, cricket chirping, let me excited, let me excited, it is clearly a wonderful music, let my heart be full of fantasy. So I pestered my father to take me to catch crickets. Dad couldn't beat me, so he took me to the grass by the river downstairs in the community and started a big arrest.

What do we hear in a pile of rocks? Hey? I asked my father: Why do you only hear crickets, but you can't hear crickets? Don't talk, it's under that red brick. ? Dad whispered. With the cry, we slowly approached? Target? Dad held the prepared net cover in one hand and gently lifted the brick in the other. I stood by and stared at it. I saw my father under a net, and cricket struggled desperately in the net, as if to say, let me out, let me out. ? We put the crickets we caught in a small jar with mud prepared in advance and raised them like babies.

Cricket is also called cricket, which is an aggressive and fun insect. It has a suit of black armor, a pair of long tentacles, a pair of purple-brown and shiny thin wings, six fat legs that can jump well, and two sharp teeth. It is a sharp weapon when fighting with the same kind.

Crickets were afraid of me at first. When they saw me approaching, they immediately retreated behind the jar, waved at me with their tentacles, stared at me with their big teeth open, and their hind legs retracted, looking very nervous. After a while, seeing that I didn't mean to hurt it, I started slowly in a small jar, but I still stopped to see me from time to time. Let me have a strong interest in it and want to know more. I teased him with a piece of Mao Mao grass, and he was like a general. He shouted with great strength, as if to say, Go away, this is my place, and don't bother me! ? Hehe, he is really a guy with only personality.

I found that crickets kept flapping their wings when they sang. Why? I ran to ask dad. Dad told me meaningfully; ? Crickets sing by rubbing their wings. ? It turns out that the secret of cricket's singing lies in its wings, and I suddenly realize.

Funny and singing cricket gave it to me? Eleven? Holidays bring endless fun!

Observation diary 300-word encyclopedia of plants

The first article: diary of observing mung bean germination

I used a plastic bottle, filled it with some soil, planted several mung beans, watered them, and began to wait for the mung beans to sprout.

A few days later, both Hushi Duomo and Mung Bean successfully produced green seedlings. I looked at them and felt that they were fighting with sharp broadswords like knights, trying to figure out who was the first to emerge and who could see the wonderful world outside.

A few days later, I found that my bean sprouts have grown tall and grown up. I measured it with a ruler, but I didn't expect it to grow two centimeters faster and one millimeter slower. I am so happy that I hope the mung beans I grow will grow faster and faster.

About three or four days later, when I went to see my bean sprouts again, I found that they were a little longer. Although I am happy, I am still a little disappointed, perhaps because I can't measure how long their roots are. Because if you have the length of roots, you can know what their total length is, which slightly narrows my doubts about these mung bean seedlings.

After a period of time, these bean sprouts unexpectedly grew some round little things inexplicably. I looked around and didn't know what it was, so I asked my mother. I didn't know it was their fruit until I asked! But I want to take them off again. I like this little thing very much, but I still hold back. See what else will grow.

Through this incident, I understand that everything should be patient, but not anxious.

Chapter 2: Observing my favorite asparagus.

There are many beautiful and famous flowers on my balcony. But the smallest and most inconspicuous asparagus in the corner of the balcony is my favorite and cherished plant.

Asparagus is light green when it first grows leaves. As she grew up, the color turned green. The leaves are yellowish. Look at her getting bigger, as beautiful as maple leaves in autumn.

The branches of asparagus are light green, and the color below is brown with a little green. There are branches on the branches, and the more they go up, the more tender they become. At the tip of the blade, you can hardly see any green, only a little yellow. The leaves spread to the left and right, and the leaves are as thin as silver needles. Who would have thought that such a beautiful plant was created by nature?

Whether it is cold or hot. No matter whether it is windy or rainy, asparagus is still so strong and tenacious. Asparagus orientation is a good example for us to be human. The wind will only make asparagus softer; Rain will only make asparagus more beautiful. No matter what you encounter, you can't resist the persistence of asparagus.

Chapter 3: Observing the plants in the community.

Walking in the community tonight, I thought of the homework assigned by the science teacher, and I decided to start from? Science? Observe all kinds of plants in the community.

The plants in our community are typical varieties of Ningbo, mainly including trees, flowers, herbs and fungi.

Qiao Muyou: camphor; Ginkgo biloba, known as the living fossil; A symbol of noble pine trees; A osmanthus tree whose flowers can make tea; There are also humble elms with crooked necks standing on both sides of the main road.

Flowers bloom all year round in the community. They are: azaleas and wisteria that bloom in spring; Gardenia and crape myrtle in summer; In autumn, the low osmanthus trees also come to join in the fun; There are two kinds of camellias: one is open in spring and grows taller; The other is in winter, and it is short, only more than a foot high; There are also Chinese rose flowers, which bloom every month.

Grassland is the least noticeable in the community: large lawns are planted artificially; The others are weeds. They are tenacious and happy. I know plantain and clover, but I don't know some.

There are also special plants in the community? The smallest house in the world? Mushrooms? . Especially after a light rain, you will find many small mushrooms in the grass and under the big tree.

In the community, most plants are green. The leaves of these trees and flowers shine like a layer of wax. Only ginkgo trees are deciduous plants. In autumn, its leaves turn yellow and fall. Weeds are all millet, and they all die in autumn.

I learned a lot through observation and combining with science books. How wonderful nature is!

Chapter four: Observe the big jujube tree in the neighbor's house.

There is a big and tall jujube tree in my neighbor's house. I found that it is composed of three parts: trunk, leaves and roots. I heard from my father that its circumference is seventy or eighty centimeters, and I can't carry it alone. Its branches stick out like a pair of huge arms. Every spring, jujube trees are covered with colorful yellow flowers, hanging on the branches, which is particularly beautiful. After a period of change, small flowers blossom and bear fruit. In autumn, the dates on the jujube tree are ripe, and those pearl-like dates look like countless stars all over the sky.

On the rest day, I go to pick the day with my children. Some beat them with sticks, some threw them with stones, and some courageous people climbed up the tree to pick dates. Put one in your mouth, it's crisp and sweet, delicious! Everyone is looking for fun from picking dates, and everyone is having a good time.

Chapter 5: Observing Impatiens and Chlorophyll

As soon as I got up this morning, I went to see my impatiens and chlorophytum. They seem to have changed a little.

I found that the leaves of red impatiens should be dry, but after I watered them, I didn't expect their leaves to turn green. The leaves that should have turned yellow absorbed water and grew vigorously. Suddenly I found a bug lying on branches and leaves. I don't know what it is doing. Are you attracted by those bright greens? Stealing vegetables, I quickly asked my mother to take them alive. Impatiens have opened a few more flowers. Those flowers that bloomed before returning home have already bloomed. Seed bag? Those seeds are ripe and will explode at the slightest touch. Now some flowers are still in full bloom and some have withered. Those flowers that have not yet opened are in bud, showing great strength. The purple impatiens is not so lush, the flowers are sparse, and the leaves look less robust, but he is still trying to be the first. The flowers that have just been thanked have also been planted, and some new leaves have turned green. I believe that after my labor, it will bloom more luxuriantly.

The leaves of that pot of chlorophytum are greener and more tender. There are almost no yellow leaves. It is so healthy that it shows its strong vitality in the scorching sun. Yes, what are you afraid of? Don't look at it so inconspicuous. As long as it has the spirit of struggle, it dares to fight the heat. What a strong chlorophytum! Small plants dare to resist such a hot environment. How can we children be intimidated by difficulties? You see such a small chlorophytum, not afraid of heat and difficulties, so let's learn its spirit, study hard and climb bravely.

How's it going? I raise it well! Impatiens are beautiful, and chlorophytum is also beautiful. You also have a look! Today's harvest is really a lot, and I know so much.

Chapter 6: Observing Soilless Plants

This year's Arbor Day, I tried to plant a pot of love grass with a new cultivation method. I'm telling you, it's soilless culture! You will definitely ask: what is useless? Water? No, I use the most popular pottery carbon balls to cultivate them. What's its full name? Negative ion implantation of ceramic carbon spheres? . The characteristics of planting with pottery carbon balls are clean, which will naturally release negative ions to purify the air after contact with water. It also has the function of water purification, and it is sterile and insect-free, which makes the planting more beautiful. How's it going? Does that sound tempting?

Start planting grass! First of all, I pour the green, white and red pottery carbon balls into a small glass container that is not broken, add water to the same height as the pottery carbon balls, so that the pottery carbon balls can completely absorb water, then evenly sprinkle the seeds of love grass on the pottery carbon balls, water them once a day, and pay attention to moisturizing. Next, we look forward to the germination and long leaves of these grasses!

On the first day, the seed lay quietly on the pottery carbon ball, but I felt that the volume could be a little bigger, and I didn't feel any different. I'm getting a little impatient. Two days later, the seeds in twos and threes began to spit out white and tender buds together. I am so excited! After that, the seeds germinated in a large area and the buds began to turn green slowly. On the fifth day, the seed became a seedling with two leaves! You can imagine how excited I am!

Now, more than half a month has passed, and my love grass is growing every day. The longer the heart-shaped Harrison is, the deeper the white root is. It brings me surprises and happiness every day.

Chapter 7: Observing Jasmine

There are two pots of jasmine in my house. Molly has lived in my house for three years, and after three years, Molly doesn't look very tall. It has been planted in a flowerpot. The branches are not so thick, and the skin is wrinkled, like the skin of a crocodile. Leaves are green and shiny, but they don't stay soft all the time. Green leaves, after a long time, will gradually grow old, harden, grow bigger and darken. In winter, the leaves of jasmine will wither and sprout again in spring.

When the flowers bloom, they are white and have a faint fragrance. From a distance, they shine like white jade. There are about seven or eight petals. They don't bloom one by one, but several flowers bloom together. Some flowers are alone in the branches, as if looking for a partner; Some three or five flowers together, as if whispering; There are seven or eight flowers together, as if in a meeting. Some are in bud, like shy little girls who dare not show their faces; Some are half open and half closed, like holding a face with delicate little hands; Others hold their heads in full bloom, dress up beautifully and show their beautiful smiling faces to people. Petals are like cradles, stamens are like babies in shaking blue. How interesting! Every time the flowers wither in summer, my mother will sprinkle chemical fertilizer on the flowerpot so that more and bigger flowers can bloom next time.

I love my jasmine, and I hope it can grow up healthily in our family.

Chapter 8: Observing Cactus

Early this morning, there was a strong wind outside the house, which made the leaves fly all over the sky.

Grandma is cleaning up her side dishes in front of the door, and I'll help. I saw many flowers planted by grandma withered, but one pot of plants was still green. Grandma said that was? Cactus? . Cactus is ugly, shaped like a human palm, dark green, and its surface is covered with tiny spikes. Those that sting like cacti? Spear? Protect it from harm. I looked up the information of cactus on the computer and learned that the body of cactus is a stem and those thorns are its leaves. It is that shape of leaves that protects cactus from harsh environment. Everything in the world is really amazing. They will change with the change of environment, and strive to adapt and survive. Shouldn't we humans also have this spirit?

Chapter 9: Observation? Plant bully?

I planted a plant myself last year, but I can't name it. This plant has just sprouted from a small bud to look like several plants from a distance, from an unremarkable seedling to occupying the whole flowerpot.

This little plant grows very fast, almost every day, every day and every night. In the past, there were many plants that could bathe in the sun in the flowerpot, but since the little plant grew out in June this year, other plants have been in the dark. Except for the plant that is taller than the small plant now, all the others have died one after another. It can be seen how lush this small plant is! I call it? Plant bully? .

In fact, there are many things to observe in life. As long as you pay attention to observation, everything written in your mind can become an observation diary. If you write well, you can let others take a quick look. What can be observed in life is within reach. If you can't write it, it's only because you don't pay attention at ordinary times!

Chapter 10: Observing Sunflowers

This morning, I found that sunflower seedlings have grown much taller. I measured it with a ruler. The highest is 6.2 cm, and the lowest is 2.9 cm. In addition, two new green leaves have grown between the original two leaves. I think they are standing there motionless like tall and straight soldiers.

Because sunflowers grow in the direction of sunlight, all six seedlings grow in the same direction. Dad said it was phototropism of plants. In order to make them grow straight, we changed the direction of the flowerpots to see if they would grow straight.

I also found some small plants growing in the flowerpot, and these small plants are equally long.

;
