This afternoon, my father called me downstairs, I ran to the house, my father pointed to a corner, I looked, saw many bees next to a thing, I came closer to see, it turned out to be a bees' nest, I backed up a few steps, for fear of being bees philosophical a bag, I squatted on the ground to carefully observe, only to see the bee's abdomen has a yellow and black stripes, the back has a pair of white and transparent. The bees have yellow and black stripes on their abdomen, a pair of white transparent wings on their backs, and a pair of antennae on their heads, and they fly up and down.

The honeycomb has many holes, and the bees fly in through these holes when they are done collecting honey.

I went to a flower and found a small bee collecting pollen, using the front four feet to collect pollen on the stamen, and then getting it on the back two feet. After picking this flower, it side will vibrate wings to fly to another flower, not long after the feet covered with pollen flew back to the hive .

Bees are so hardworking!

Today after dinner, I walked into the bathroom, I saw two long, thin shape, black and red, black and red color bugs crawling on the ground, I was shocked and screamed.

My mom arrived at the sound, saw the worms on the ground, and said ": Don't be afraid, this is earthworms, the weather is relatively humid, and I do not know where it comes from". I listened to my mom's words, only to put down the heart to observe earthworms. The earthworm has a thin and long body, a pair of small indescribable eyes, and a tail that can not be seen with the naked eye.

At first, I threw a toothpick at the earthworm, but it didn't care and kept crawling. After a while, I took some salt and sprinkled it on the earthworm, which twisted its soft body violently, and turned over fiercely a few times, and then stopped moving.

Next, I sprinkled some water on another earthworm, and the earthworm wasn't afraid. After a while, I sprinkled some sugar on the earthworm, and the earthworm's body moved, swaying from left to right, and after a while, it didn't move.

Tonight this discovery let me know the earthworm.

Article 3: Observation journal 400 words fourth grade classic

Today, I did a small science experiment to observe what ants love to eat?

I put apple cores, sugar, salt, dead insects, white rice in the center of a vacant lot, and then squatted next to watch. 15 minutes passed, half an hour passed, an hour passed, "bait" on the "scout" still did not come. I was so angry, that I took the "bait" to the center of the neighborhood and watched it. I was so angry that I grabbed all the ants that passed nearby and put them on the "bait", but they flew away as fast as they could. I was so disappointed!

I analyzed the reason carefully: the reason why the "bait" is "unattended" is probably because it is too far away from the ants' nest. So I moved the bait closer to the nest. So I moved the bait near the ant nest. It wasn't long before the ants came in pairs. They were busy carrying food, but there were some selfish ones in the colony. Instead of carrying food, they only knew how to eat, and they ate so playfully that one of them even died! To be honest, I don't know how it died, just guessing.

However, the sugar was all moved and eaten, and the other "bait" is still "unattended". Therefore, the ants love to eat sugar.

Article 4: Observation diary 400 words fourth grade classic

This morning, the sun is shining, I went to the wetland park with my parents to observe small animals.

We drove to the wetland and parked the car. We came to a forest where there was not a single small animal, only some plants. Although we heard birds chirping, we didn't see any small birds. I immediately said, "We can split up and look for them." Then I was in a group with my mom and my dad was in a group by himself, so we started to look for the critters.

Mom and I came to the bamboo forest and looked carefully. Suddenly I shouted, "I see ants." Mom immediately ran over to look with me. I first sprinkled some of the fruit on the ground to attract ants. When one ant saw it, it immediately touched its antennae with the antennae of another ant, which was said to be a message they were passing on in the book. In this way one ant passed on to another, and soon there came many little ants, and together they carried away this big thing. I guess this fruit is enough to last them all winter. I also noticed that two ants were carrying the fruit in their own direction, but they were going in opposite directions, and as a result, neither of them could carry the fruit away. After a while, they realized this problem, and then they talked it over, and headed in one direction, towards the ants' nest.

After an hour and a half of observation, my mom and dad and I went home with a smile.

Part 5: Observation diary 400 words fourth grade classic

Today, when I came home from school, I just got off my mother's electric car, I saw a group of ants moving. They were lined up in a neat line and were busy in an organized way. I squatted down to observe carefully.

I thought to myself: they have been busy all day, their stomachs should be hungry, right? So, I casually broke a quick bun and put it on the ground again. An ant crawled over and sniffed it and walked away. After a while, and then came a few, sniffed and went away, did not have the intention to move. The buns were too big to move, so I broke them into pieces. After a while, they still sniffed and walked away. I just don't understand, so I hurried to the house again and took another cookie down. Sure enough, in less than a moment, a fast-eyed guy jumped up, hands on the move, but it made a nine bulls and two tigers. But the cookie didn't budge. It stopped and seemed discouraged, but after a minute or so, it quickly crawled toward its nest. A few minutes later, it was followed by about ten ants, who had gone to get help. The ants reached the cookies with glowing eyes. Then, some of them in front of the pull, some in the back of the push, some in the side of the lift, looking at them so diligent touch, I can not figure out, just steamed bread why they do not want it? So I went to ask mom, mom said; "I do not know ah?" .

I looked up the information on the Internet, it turns out that they are eating meat and not vegetarian, haha, nature's creatures really interesting ah.

Part VI: Observation diary 400 words fourth grade classic

Today I came to the beautiful park, where the sun shines and flowers bloom! I sat on a chair looking at the scenery while enjoying a delicious cookie. Suddenly I realized that there was a group of black things walking around under the chair, so I took a curious look, oh! It turned out to be a few ants! At first I didn't pay much attention to them, but then my eyes were gradually drawn to them. I became more and more interested in them, so I squatted down to observe them. Oh! It turned out that they were carrying the broken pieces that I had dropped when I was eating the cookies. They were struggling like hell. I counted about five or six ants. When I saw how fast they were moving, I had an idea: put in more cookies, will they move like that? So I put a big leftover cookie of my own down. Haha! They really couldn't move.

But after a while there were a few more little ants, and now there are almost ten little ants. Maybe they used their antennae to send out a 'support signal'. They are ready and about to make the 'final blow' to carry the cookies home! When I saw this, I was worried about them too, I thought they couldn't move it, but then the ants worked together, yikes! They finally got the cookies home. I crouched down on the ground and looked at the ground, and was dumbfounded: how can a small ant move a big cookie? After a while I woke up, I look at the time is not early, so I hurriedly ran home!

On the way home, I was thinking: the original ants as long as the unity is also very powerful, I do not want to look down on some small animals. And I have to learn the spirit of unity of the ants!

Article 7: Observation diary 400 words fourth grade classic

Today, my father and mother and I came to my grandmother's house to play, my father was concerned that I was bored at my grandmother's house, so he caught ten snails in the field for me to play. I looked carefully at the ten little cute, but found that there are seven snails shell is "right-handed", while the other three snails shell is "left-handed", and their shells have many colorful stripes and stars spots, beautiful.

I put a few leaves on them. However, only one snail left a big pit on the leaves, while the other snails did not even touch the boulder, I went to ask my dad with questions. Without saying a word, my dad took a piece of chicken and put it in the trough, and the snails immediately "dashed" over and ate it with great relish. Dad looked at me confused, explained: "snail's food is diverse, some snails like to eat brindled food, some snails like to eat vegetarian, there are snails brindled uneven it! "Listening to my father's words, I suddenly realized.

I found a strange phenomenon of snails: all ten snails are laying eggs! I thought: Dad caught the snails in the wild, there must be some male and some female, can not be all female ah! I looked up the information on the Internet, and finally realized: the original snail's body has two genitals, one is the male genitals, the other is the female genitals, so the snail it is both "Mr." and "Mrs.", how, it's very interesting!

A small snail has so many secrets, I believe that as long as we carefully observe everything around us, we will find more secrets of nature!

Article 8: Observation Diary 400 words 4th Grade Classics

Today I had nothing to do and saw a few snails. I then observed them.

The snail had straight tentacles on its head. Its round eyes seemed to grow on the straight tentacles. On its back, it carries a big, round "house" with a pattern of circles printed on the snail's big "house". It doesn't have legs to jump around, so it can only crawl forward slowly.

I'm going to let all the snails compete in a crawling race on a two-tile grid. At first, the snails' sense of direction was fine. But after a while, the snails began to go in different directions, one snail crawling to the left, accidentally, it fell down the steps. I ran down the steps, worrying about it: would it die? When I got to the edge of the steps, I saw it sticking naughtily to the edge of the steps. I slowly picked them up, put them into a bottle, and put them into the small pool. It was getting late, so we went to bed together.

The snail has grown up. The last time I saw it, it was as small as the fingernail of my middle finger, and now it is as big as the fingernail of my thumb.

I organized a crawling race for them. I wanted to see if they had gotten faster as they grew up? I observed them for a long time and felt that they were still as slow as ever. I thought the snails might be over-starved to run fast. So I brought enough vegetable leaves and bread crumbs. The snails crawled slowly and ate slowly, and it took a long time for the food to diminish. It was easy to wait until they were full before they crawled slowly again.

So I came to the conclusion that the snail is growing up, but not faster.

Observing things around us is so interesting and fun! If you don't believe me, you can experience the fun of observation.
