Fourth grade observation diary
At the end of the day, there must be many unforgettable moments that need to be summarized and recorded in the diary. But I found that I didn't know what to write. The following is my carefully arranged observation diary for the fourth grade. Welcome to read the collection.

There are four turtles in my family, one big and three small.

The tortoise has a long neck, a pair of small round eyes on its head, always looking around, four short and thick legs under its belly and many small squares on its back.

Turtles eat a lot and like meat. They eat more meat than I do every day. They are very timid. As soon as they heard something, they quickly shrank their heads into the turtle shell, and after a long time, they dared to lean out a little slowly. In a few minutes, they will feel that there is no danger at all, and then they will stick their heads out with confidence.

The tortoise is very shy. If a stranger approaches him, he will quickly put his head into the turtle shell and stay there for a long time. But if you see me coming, but you stick out your head and wag your tail, it seems to greet me kindly: hello, young master, hello. ...

My turtle is really cute.

Diary of Grade Four Observation II: As soon as school was over today, I took out my cup and mung bean in a hurry.

I put the water in the cup first, and then put more than 10 mung beans in the water for observation.

When mung beans were just thrown in, they blew a few small bubbles in the water and slept there quietly, refusing to move or twist. I'm as anxious as an ant in a hot nest, running around.

This is, the mother on the side said, "I'm afraid there won't be any big changes today." Why not observe it tomorrow? "

The next morning, I couldn't wait to observe. "ah!" I cried, the water turned yellow, and mung beans became fat. It's bulging, and some skin is cracked. I was also surprised to find that the crack had sprouted.

It turns out that planting mung beans is so interesting!

There is a big stone beside the teaching building, engraved with two big red characters "Book Rhyme". There are many flowers and trees planted next to that stone, including beautiful and elegant flowers. who is it? It is the flower of the beautiful messenger of spring.

The petals of winter jasmine are bright yellow and divided into two layers, each with six petals. Smell it with your nose, ah, you will smell a fragrance and immerse yourself in the flowers. At this moment, you suddenly feel refreshed and happy to study. The branches of the winter jasmine are green and drooping. The branches are long, narrow and dense, like long-haired girls stretching their green hair. When the breeze blows, it gently shakes and floats, which is beautiful and clean.

Winter jasmine is neither so red as roses nor so yellow as marigold. Its small and exquisite appearance makes people love it.

Ah! Love winter jasmine. Winter jasmine, the beauty of winter jasmine, is the thunder of stuffy days. Good people have their own strengths, while bad people feel inferior. It is the messenger of spring, full of vitality. My classmates and I often read and play in the flowers. Ah! Winter jasmine, what a beautiful flower! It is the messenger of spring. Ah! Beautiful messenger. Ah! I like it!

One day, my grandmother and I went to the vegetable market to see shells.

I found many shells in the vegetable market, such as gnats, melon seeds, flower shells, snails and so on. We picked up a lot of shells, black and white, very beautiful!

After my observation, I found that the cockroach's shell is very fragile and the ink is not easy to disperse; Xianbei hard, ink easy to disperse. I thought to myself: sea melon seeds, small, should be very soft? I didn't expect the shell to be so hard, harder than gnats! I also found in the photo: our scallops are bigger than wheels!

Their shapes are very beautiful, such as sectors and circles. They are colorful and beautiful! Besides their shapes, their patterns are also very beautiful. There are waves, spirals ... countless.

On Sunday morning, I planted ten small mung beans in the flowerpot. I carefully turned the soil and watered it. After a whole day, I drilled a few small buds from the soil, which were tender green and very beautiful.

On the third night, when I went there, I saw a small bud turned into a small watercress with two petals and a dark green color.

After a few days, watercress slowly turned into small leaves, and each tree had several small leaves.

Later, the small leaves grew taller and taller, and the leaves grew bigger and bigger, more and more, and grew quickly. I am very happy. I water it on time every day.

Little Doudou, grow up quickly and let me know what you will become when you grow up. I hope you will blossom quickly and bear more small mung beans!

During the summer vacation, it was very hot. My mother and I went to the zoo to observe animals.

As soon as I entered the zoo, I saw many animals, including golden monkeys, elephants and hippos ... I couldn't wait to run over as soon as I saw hippos, because I was a hippo lover. However, to my disappointment, every hippo sank to the bottom of the water, just like a shy little girl, refusing to show up. So, I thought about it and finally came up with a way to lure hippos with food. I quickly took all the food in my pocket to the hippo and finally lured the hippo up.

I quickly observed the hippo carefully and suddenly found that the hippo's skin secreted a red sticky water drop. I thought: Is this a hippo injured? After returning to China, I found information about hippopotamus, and learned that the red water drop is not because hippopotamus is injured, but called "sweating blood". And "sweat and blood" is its sunscreen lotion, in order to avoid sunburn of fragile skin.

During the summer vacation, the teacher assigned us a special task, planting plants and keeping an observation diary.

I took pepper seeds, planted them and watered them to loosen the soil. One day passed, two days passed, three days passed, and they still showed no signs of sprouting, which made me very disappointed and walked back to my room.

Time flies. When I came to water the pepper, I found that it had grown, but it was still very short. Although it is short, it is still very long. I hope the stars and the moon are really useful these days. Pepper has leaves. It is oval, thick at one end and thin at the other. I touched it with my hand and felt that the leaves were still fragile. In the remaining days, I watered the peppers, and loosening the soil became my daily routine. I put it on the balcony in the morning to let him feel the fresh air. I put it at home at noon because he can't stand the sun exposure. At night, I give it loose soil and glue to make her grow stronger.

I found that the pepper I worked so hard to cultivate grew, and I was overjoyed and extremely happy. Through this, I know that I should keep working.

Today, I observed ants at the door.

Suddenly, I found a big ant looking for food and immediately put a little bread crumbs. Then the big ant saw the pie falling from the sky, smelled it first, then looked around, and then went back to the nest to help. After a while, a large group of ants came out of the nest. After a while, the ants removed the crumbs. At this time, there were many ants crawling around where the bread crumbs were originally placed. I saw it and immediately put a little bread crumbs there. When the ants saw it, they stopped crawling and went to grab food.

After a while, several fallen soldiers in the ant army ran back to the cave.

There are many plants in my family, including chlorophytum, Milan, green radish, Zhu Dinghong, aloe, jasmine and so on. My favorite is those two pots of aloe.

Aloe vera is green all year round, standing upright in a flowerpot, like a sword. There are many white spots on the surface of aloe leaves and small thorns on both sides. Its leaves feel fat, thick and comfortable, like pinching a balloon. Aloe vera is very afraid of cold. In winter, my mother moved aloe to the living room.

Mom said that aloe can absorb harmful substances in the air and purify the air. People call it "purification angel", which is really deserved! Aloe can also be made into medicine. I often see a kind of medicine "Aloe Soft Capsule" in the pharmacy where my mother works, which is made of aloe and can moisten the intestines and relax the bowels. Aloe can also be made into facial mask. My mother often uses aloe mask to whiten her skin in summer.

Aloe vera is very effective. I like aloe vera!

Today, I am grateful for a whim and want to observe a flower. Thinking of this, I took a magnifying glass, tweezers, ruler and other tools and went to the playground to observe.

I came to the flower bed. To my disappointment, there were only some green grass in the flower bed, and there were no flowers there! Suddenly, I found a little blue thing next to the flower bed. Walking in, it turned out to be a small blue flower. It suddenly dawned on me that wild flowers usually grow in corners now!

I picked up a magnifying glass to observe it. I found that the stem of this flower is very long, and the longest is 25 cm. Its leaves are about 1 cm in diameter, which is twice as big as flowers. The most remarkable thing about this flower is its flower. This flower consists of stamens, pistils, petals and sepals. It's a perfect flower, bisexual flower. This flower has two stamens, 3 mm long and a black spot on it; The pistil is as long as the stamen, only one, white, without black spots; There are four petals, 3 mm in diameter and blue; There are also four sepals, which are green and 5 mm long.

After returning home, I told my mother the observed data. My mother said that I really like to observe things around me.

Today, the teacher asked us to keep an observation diary, so I soaked beans.

I prepared a stainless steel basin with a diameter of about 10 cm. I took out a lot of beans from home and caught a handful. Turn on the tap and get some water in the basin. Take out a towel, wet it and wring it dry, and gently put it on it. I put the beans in a sunny place again, because I think it grows fast in the sunshine. Looking at the beans, I thought to myself: can you sprout and grow up quickly?

It will be fine on Friday, September 2 1 Sunday.

As soon as I woke up this morning, I couldn't wait to see my beans Taking away the towel, I found that my beans had 10 mm full buds! The change of beans is really earth-shaking. From shriveled to tender bean sprouts. I am very happy!

Looking at the new bean sprouts, I can't help thinking: you have changed so much!

I excitedly told the whole family that my grandmother said, "When bean sprouts grow up, they can cook." I can't wait to eat my own bean sprouts.

Today, the teacher asked us to soak soybeans to write a composition. I am very happy after hearing the news!

After coming home from school, I first took out a lunch box with a diameter of 8 cm, and then took out a handful of soybeans and put them in the lunch box. I turned on the tap, took a little tap water and put it on the balcony of the living room. Because I think they will grow faster in the shade, and I hope they will grow up soon.

It will be sunny on Thursday September 20th.

When I came home from school today, I was excited to see the soaked soybeans. I found a small crack in the bean. I happily changed water for them, thinking: Will the beans sprout in a few days? After I changed the water for the beans, I called my mother and asked, "Mom, will the beans sprout in a few days?" Mom smiled and said, "Of course they will sprout, but you have to change water for them!" " "

Saturday, September 22nd is fine.

I worked hard to change the water for them for a few days. Today, the soybeans finally germinated, and I almost jumped with joy. I'll ask my mother to come and have a look. My mother touched my head and said, "Look, has the soybean sprouted?" ! And have you found that soybeans can grow slowly without any fertilizer and only need water? "

I'm so happy that my beans have finally sprouted!

Today, the teacher assigned a special assignment-soaking soybeans, and let us carefully observe and record the growth and changes of soybean germination.

First of all, my mother and I prepared a small basin with a diameter of about 20 cm. Then, I caught two small, yellow and hard soybeans and put them in a small basin. Then I filled the small basin with cold water. Finally, I prepared a piece of cotton gauze and covered it. In order to avoid direct sunlight, I put small soybeans in the corner of the kitchen and observed them quietly.

At this time, how I hope that soybeans can germinate as soon as possible. ...

It will be cloudy on Thursday, September 20th.

After dinner today, I can't wait to see my soybeans.

I opened the gauze and looked, ah! Soybeans are sprouting! The white and tender stems are exposed, about 1 cm long, as beautiful as tadpoles with just grown tails, so cute! So I added new water to the small soybean, leaving only a little water in the basin, then covered it with gauze and continued to wait.

Seeing this, I am curious and happy. I really hope to see the soaked soybean sprouts as soon as possible.

Saturday, September 22nd is fine.

As soon as I got up this morning, I hurried to see my soybean sprouts.

Through careful observation, I found that soybeans have turned into light green beans, bean sprouts have grown to almost three or four centimeters, tender stems have become thicker, and the "coat" of beans has begun to fall off ...

I am very excited at this time! Very excited!

I ate soybean sprouts at noon today and went home from school in the afternoon. I just want to see how soybeans germinate. So, I prepared a plastic cylinder with a diameter of 20 cm. I mix hot water and cold water to make warm water. I grabbed a handful of soybeans and put a piece of gauze on the cylinder.

I looked at the soybean and thought: When will the soybean sprout?

It will be fine on Friday, September 2 1 Sunday.

After dinner today, I went to see my soaked soybeans. Some soybeans become full and seem to crack soon. Some soybeans have been peeled and some soybeans have sprouted. I changed the water for the soybeans and put the gauze away, thinking: Will the bean sprouts grow out soon?

Mom and Dad said, "This bean sprout will have to wait for another two or three days. Don't worry, wait slowly. "

Monday, September 24th is fine.

After dinner tonight, I went to see my soybeans again. I found that all the bean sprouts have grown out, thin and long, at least 5 cm long, some crooked and some straight. I am very excited. I went to ask my grandmother, "Is the bean sprout ready to eat?" Grandma looked at it and said, "It should be ready to eat. We will fry bean sprouts tomorrow. " After listening to grandma's words, I am extremely happy!

Today, the teacher asked us to go home to soak soybeans and write an observation diary. After I came home, I made soybeans with the help of my grandmother.

First of all, I took a small stainless steel basin with a diameter of about 15 cm from the kitchen, found a bag of soybeans, grabbed one and put it in the small basin. Soybeans don't need washing. I directly connected half a basin of cold tap water to the water pipe and found a damp gauze to cover them.

I am very excited and looking forward to it. I wonder when soybeans will grow up and what they will look like when they grow up.

It will be sunny on Thursday September 20th.

I got up this morning to see soybeans. The soybeans in the small pot are much heavier than those in the previous two days. They swell like chubby dolls, and the skin of soybeans has fallen off, revealing a chubby body in vain. There is a small crack in the middle of the soybean, from which small white bean sprouts emerge.

I'm so happy that the soybeans have finally sprouted. I think the bean sprouts should be ready to eat in a few days. I can't wait for them to grow up quickly.

It will be sunny on Sunday, September 23rd.

Soybean sprouts are much longer today than before. There are two small green leaves at the root of soybean sprouts, and some of the soybeans on the top layer have turned purple.

I'm a little worried about whether the bean sprouts are rotten, but just listen to my mother and take out the discolored beans. I felt a sort of surge of relief. I'm glad my bean sprouts are edible and I learned to soak them.

Fourth grade observation diary article 16 September 18 Tuesday sunny

Today, the teacher asked us to keep an observation diary. I wanted to observe the cultivation process of bean sprouts, so I went home and made preparations.

First of all, I prepared a rectangular container about 16 cm long and 12 cm wide, and asked my grandfather to soak soybeans. I grabbed a handful of soybeans from the bag in the closet and put them in a container full of water, which is warm water mixed with hot water and cold water. Everything is ready except a suitable place to store beans. As soon as I thought that all the good bean sprouts were soaked in the "cave", I found a dark and humid place to store the beans at home. I really look forward to amazing changes tomorrow morning!

Friday, September 2 1 Sunday turns sunny to cloudy.

Today, my bean sprout cultivation process is finally over, and I have made gratifying achievements. Beans grow long, thin green buds with different shapes. Some of them are forked like the English letter "Y", some are like winding "earthworms", and some have two secondary buds from the main bud, like Poseidon's "Trident" in Greek mythology, which really makes me overjoyed and excited!

I feel very happy and happy when I see the harvest of my labor!

A few days ago, my mother gave me a special gift-mung bean. My mother told me to raise it and turn it into mung bean sprouts.

First of all, I picked up mung beans and looked at them carefully with discerning eyes. Mung beans are very small, dressed in green and tied with white lines, just like a white belt. This may be where they germinate! Then, I put my mung beans in a bottle cap of Nongfu Spring filled with water, and the water didn't reach the beans. This is my idea: Xiao Doudou, Xiao Doudou, you must grow up quickly!

After two or three hours, I came back from the supermarket and found that Xiao Doudou's "clothes" had changed and wrinkled, as if it was hot, and he wanted to take off his clothes; Some have cracked, and a thin bud wants to break free from it. How interesting!

The next morning, I got up early and went to the balcony to see my little peas. "Hey, how did my beans turn white?" Suddenly I found a layer of green skin next to the beans. Oh, it turns out that mung beans will peel like silkworm babies, and they can germinate normally after peeling. Look! This is my great discovery today. I hope I can find something better in a few days. It's a pity that I'm going back to my hometown. My mother will take care of mung beans for me these days!

Two days later, I came back and saw a pair of wings-small, green, so cute! The stems are turquoise, and the small peas grow beard-like roots, which are put in the sun and have a little bright light. ...

I finally achieved my goal and became a mung bean sprout.

I saw Fabres's Insect Story the other day and was deeply attracted by the story. I thought of watching the growth process of mung bean sprouts.

So I grabbed a round mung bean and put it in a glass, and put some water in it. The next day, I found that mung beans seemed a little fat. Another day passed, and it opened its green clothes, revealing the skin as smooth as a white fat doll. I really want to touch it! On the third day, the mung bean changed slightly: its body was soft, and a "white tail" appeared behind it, just like the elephant's white teeth. I know this is mung bean sprouts! Another day passed, and I found that the mung bean sprouts had not changed, which worried me. On that day, I couldn't eat well and sleep well. Another day passed, and I was surprised to find that the mung bean sprouts became longer. These buds are like brothers and sisters of multiple births, as tall, as white and as tender. I was so happy that I immediately called my grandparents and parents. Our whole family was very happy. The next day, grandma said it was ready to eat, or it wouldn't taste good when I was old! I can't bear to look at these fragile elves! These mung bean sprouts are also looking at me, as if to say, "thank you, little master, for bringing us to this beautiful world!" " "

At noon, mung bean sprouts were fired by my mother. I really can't bear to eat them! Let me take a bite, ah! My mung bean sprouts are much more delicious than those sold in the market!

I like my mung bean sprouts!

I heard that mung beans are green food, so I planted a pot, which brought me endless happiness.

Three months ago, there was a pot of freshly unearthed mung bean seedlings on my balcony. Two small umbrellas swayed slightly, as if praising my upbringing. The two delicate green leaves are very small, and the long stems are extremely slender.

Soon, a month passed, and after my careful cultivation, mung bean seedlings grew many green leaves. At this time, the stem became thicker. Look carefully, the stout stem is as thick as a little finger and about six centimeters long, and the leaves are getting bigger and harder.

After a few weeks, the leaves on the branches became denser and denser, piece by piece. At first glance, it really looks like a green bonsai! Looking at it, it's like a soldier on the grassland, standing there hard, which really makes me admire.

After a long time, the mung bean bloomed with small yellow flowers and kept stretching, laughing from ear to ear. A few days later, the small yellow flowers withered and grew long green pods. I jumped up excitedly and told my mother the good news quickly.

I wait and wait, wait and wait. Finally, the beans are ripe. I picked the pods and peeled them gently. The oval mung bean is like a green emerald, moist, smooth and full. You can squeeze water with a pinch! Mung beans like rain lie comfortably in my hands and enjoy the sunshine!

Ha, watching the carefully cultivated mung beans finally grow up, there is a joy of harvest in my heart!

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 healthily in our home.
