Observe animal and plant diaries in winter vacation, read 2 diaries in Spring Festival Evening in New Year, and help parents do a housework diary, one of which requires 400 words.

Tuesday, June 14, the weather is fine.

There are seven lively koi fish in my family. Some are big red, like a swimming little sun; Some are orange, like big oranges; And colors, like chameleons. The small fish is streamlined in shape and has a body length of 6~ 12 cm. I fed them fish food and floral rolls at the same time, and they seemed to prefer floral rolls. When they breathe and eat, their mouths open and close like small speakers, and food is sent into their mouths by suction.

Fins, which use streamlined bodies and flexible tails to grab food at a speed of 50~60 cm/s, are also very timid. When there is any movement or sound, they will run around the pool. Sometimes two fish bump into each other and flap each other's dorsal fin with their tails, as if sending a message. When they swim, their tails swing between 98 and 180 degrees. When they are very leisurely, they will "lie" in the corner of the fish pond one by one, as if afraid of affecting their companions; When you are angry or afraid, you will quickly "hide" in other fish, as if afraid that others will see you.

On Thursday, March 16, the weather is fine.

I just finished feeding fish food today. I saw a spot with a body width of 2 cm and a body length of 7-8 cm. koi fish spit out a dark green object of 2-3 cm from his mouth. After it vomited, it took a few breaths with its mouth and swam away. Several other fish have also spit out such secretions. I think this white and dark green secretion may be food they don't want to eat, or it may be stomach acid or bad bacteria in water. It seems that it is impossible to explore nature without rich knowledge!

On Friday, March 17, the rain cleared up.

Today, I hung fish food on the hook and stayed in the water for 5 minutes. A greedy little fish swam over. Suddenly, I lifted the hook, and the fish swung its tail at 180 degrees, and its two ventral fins swung back and forth vigorously. Blink of an eye, it jumped 2~4 cm from the horizontal plane, and then fell into the water, stirring up coils of water vortex. I checked the information: Carp (koi fish) does jump, the highest jump is 1 meter. Carps in rivers and lakes often jump out of the water to play at sunset. There is also the legend of "Carp yue longmen" among the people.

Saturday, March 18, the weather is fine.

Today, I want to change water for fish. Before changing the water, the fish were silent, as if afraid of being found, so they "hid" under the water depth of 8~9 cm. Even if there is something delicious, it is "waiting for the rabbit" and waiting for it to sink. But just after changing the water, the fish all shook their fins and chased each other. When feeding, everyone scrambled to eat. Why has it changed so much? Personally, I think: Although carp grew up in rivers and lakes, they are used to living without changing water for a long time. But just as people like clean homes, fish also like clean water. Clean water is not only "fresh air", but also there is no excrement in the pool. Of course the fish like it!

March 19 Sunday sunny to cloudy.

Fish like to play very much! Sometimes they pounce on food, sometimes they hit down, and sometimes they chase and play in the water. However, these are swimming fish. Won't they "walk backwards"? Through observation, my answer is yes. Don't believe me, look at my koi fish. When the little guy swims forward, the ventral fin paddles backward, and the body and tail paddle left and right, creating a vortex to push the fish forward. So sometimes they can slide for a while with the help of the current. When swimming backwards, the ventral fins paddle forward, generating a driving force similar to rowing. In addition, the tail only swings to the right or left, and the fish will naturally "retreat".

I was idle today and saw some snails. I watch them.

Snails have straight tentacles on their heads. Its round eyes seem to grow on straight tentacles. It carries a round and big "house" on its back, and it is printed on the snail's big "house" in a round pattern. It has no legs to bounce around, so it can only crawl forward slowly.

I want all snails to have a crawling competition, only two tiles. Snails have a good sense of direction at first. But after a while, the snail began to move in different directions. A snail climbed to the left and accidentally fell down the steps. I ran down quickly, worried about it: will it die? When I got to the edge of the steps, I saw it naughty and stuck to the edge of the steps. I slowly picked them up, put them in a bottle and put them in a small pool. It was getting late, so we went to bed together.

Saturday, October 7th, 2006/KLOC-0 Weather: sunny.

Today I came to observe snails again. Snails grow up gradually. Last time I saw it, it was as small as the fingernail of middle finger, but now it is as big as the fingernail of thumb.

I organized them to crawl again. I want to see if they have grown up and speeded up. I have observed them for a long time, and I feel that their speed is still so slow. I think the snail may be too hungry to run fast. So I brought enough food-leaves and bread crumbs. Snails crawl slowly and eat slowly, and it takes a long time for food to decrease. It's easy to wait until they are full before getting up slowly.

So I came to a conclusion: the snail grew up, but its speed did not increase.

It is so interesting to observe things around you, so interesting! If you don't believe me, you can experience the fun of observation yourself.

Observation diary

Shenzhen Fumin Primary School 40 1 Banluolin

I planted a mung bean at home. I water it every day and carefully observe how it grows. I will observe it for a period of time after watering every weekend.

It's already sprouting. The tender stems of mung beans slowly stick out of the soil and show their heads. The tender stems of mung beans are blue and have no leaves. After a few days, the stem of mung bean gradually turned dark green, and one or two leaves grew on the stem, which was as long as one centimeter.

There are more and more leaves on mung bean stems, up to eight or nine pieces. The leaves that grew last week grew longer and longer, and the petiole gradually couldn't bear the weight of the leaves and fell down. The shell of mung bean is gone, and the top is flattened.

Mung beans have grown to more than three meters high, just like a small tree. It has more and more branches, and its leaves are much greener, gradually turning into dark green. There are five or six filaments on the petiole of mung beans, which are very beautiful. All you have to do is gently pull the filament of mung bean with your hand and straighten it. As long as you let go, the mung bean will bounce back and bend again, like a spring, which is very fun.

We'll get the result in a while. I hope time passes quickly.

Help mother with housework.

Another Sunday, after I finished my homework, I played casually for a while and soon got tired of it. At this moment, I saw my mother at work. Suddenly, I came up with an idea to help her do some housework. What should I do? Washing clothes? Mom is already washing. Washing vegetables, mom finished washing yesterday. Tidy up the house. By the way, I want to help my mother clean the house. There is only one room left at home, alas! This will make me shine. Let me put my things in order first. Yesterday, my brother came. He threw away his toys and didn't put them back when he left.

So I had to pick them up one by one and put them back. Put the toys away. I want to put the sofa in a mess, one in the corner and the other at the bedside. I had a hard time getting the sofa out. After everything is packed, I'm going to make the bed. It's really hard to make the bed! Pull up this corner, it's crooked. Pull up that corner, it's crooked again. I thought about how my mother used to lay it. By the way, if you pull the two corners together, that's good. I tried it and it was put down. What should I do? By the way, there is a lot of dust on the floor. I'll vacuum it. I will pick up bigger things with my hands. It's really troublesome. After I finished, I was so tired that I could hardly stand up.

Through today's housework, I know that my parents are very tired every day. They cook and wash clothes for me every day and live a carefree life all day. In order to reduce the fatigue of my parents, I will help to do more housework in the future.

All right. What should I do? By the way, there is a lot of dust on the floor. I'll vacuum it up.

I just picked it up with my hands. It's really troublesome. After I finished, I was so tired that I could hardly stand up.

Through today's housework, I know that my parents are very tired every day. They cook and wash clothes for me every day.

What's more, I live a carefree life all day. In order to relieve parents' fatigue, I will

Help do more housework.

Today is New Year's Eve. I summed up what I have done and thought these days.

Helping parents is just a way to show filial piety, and more importantly, it is experienced. You can't just think about not doing things, and you can't just think about not doing things. Our parents support us, and we should repay them. How to report it? At least I should be grateful in my heart, aware of my parents' difficulties and not let them worry about us. Then we should take action to do something for them, from doing housework to supporting their parents when they are old. The most important thing to pay attention to is: consciousness and truth. Filial piety is not what others make you, but what you make yourself. Truth is gratitude from the heart, and there is nothing false.

My parents are at work these days. I clean at home, fold the quilt, study on time and arrange my time in an orderly way. In a word, I will continue to do it and help my parents with housework.

Today, posting couplets keeps me busy. My parents posted them elsewhere, leaving me alone at home. I think: I also post Spring Festival couplets for my parents. First of all, every family has put double-sided tape on the big word "fu", but there is a problem that bothers me: is the word "fu" directly attached or reversed? Finally, I came up with a way to kill two birds with one stone. The word "Fu" on the front door is posted backwards, which means "Fu arrives (falls)", and the word "Fu" on other houses is posted now. Everything is arranged, leaving couplets. The first part: the spring breeze in front of the mountain blows green, and the second part: the rising sun in Wan Lihong. Just after I sent it, my parents came back, and my mother said that I helped them a lot. Today is New Year's Eve. Good luck in the Year of the Rat and Happy New Year!

In the evening, after dinner, I saw that my mother was exhausted and had to wash a lot of dirty dishes. I thought to myself: I am a fourth-grade student in primary school, and I should help my mother do something. Now I have to wash the dishes. Hey, I will seize the opportunity and show my talents! So I confidently walked up to my mother and said to her, "Mom, I think you are very tired. Go and have a rest. This bowl is my treat today! " "My mother looked at me doubtfully and said," Can you do it? "I patted my shoulder and said," Well, I can't do this little thing, so what shall I do in the future? " Mother smiled and said, "well, I'll go to rest first." "

I went to the restaurant, put bowls, spoons, chopsticks and plates on the kitchen sink, and then poured shrimps and fishbones into the trash can. Pick up a rag and wipe the table. Ok, the real task has begun! I went into the kitchen and came to the pool. I turn on the tap first, wet the bowl, then drop a drop of detergent on the bowl, wipe it with my clean little hand, and then wash the bowl clean. All right! After washing the dishes, it's time to "bathe" the chopsticks and spoons. The more you wash, the more energetic you are, hum! I also dripped detergent, wiped spoons and plates, wiped them and rinsed them clean. It's funny, my plate can not only sing, but also spoon and ensemble. Finally, after washing chopsticks, I still dripped detergent, carefully rolled back and forth from top to bottom, from bottom to top, from left to right, from right to left, and washed it clean in the water. Ah! You're done, this pile of tableware is all washed by me, and it is still shining in the light, which can show people! After drying, I put these tableware in the disinfection cabinet, and my heart was full of sweetness.

At this moment, my mother came over. After seeing all this, her kind face showed a satisfied and bright smile. It is enough to ask questions without such a long article. Just don't write the date, don't keep an observation diary. Just write a small animal or plant. Don't do this. Paradigm agreement 1| Comment 2012-1-3119: 59 0797 873288 | Level 4.

March 14 Tuesday sunny.

There are seven lively koi fish in my family. Some are big red, like a swimming little sun; Some are orange, like big oranges; And colors, like chameleons. The small fish is streamlined in shape and has a body length of 6~ 12 cm. I fed them fish food and floral rolls at the same time, and they seemed to prefer floral rolls. When they breathe and eat, their mouths open and close like small speakers, and food is sent into their mouths by suction.

It will be cloudy on Wednesday, March 15.

Today, my little koi fish is very lively and lovely! When I was feeding, I found that they all swung their long, white tail fins and fins growing in their bellies, and grabbed food at a speed of 50~60 cm/s with their streamlined bodies and flexible tails. They were also very timid. When there is any movement or sound, they will run around the pool. Sometimes two fish bump into each other and flap each other's dorsal fin with their tails, as if sending a message. When they swim, their tails swing between 98 and 180 degrees. When they are very leisurely, they will "lie" in the corner of the fish pond one by one, as if afraid of affecting their companions; When you are angry or afraid, you will quickly "hide" in other fish, as if afraid that others will see you.

On Thursday, March 16, the weather is fine.

I just finished feeding fish food today. I saw a spot with a body width of 2 cm and a body length of 7-8 cm. koi fish spit out a dark green object of 2-3 cm from his mouth. After it vomited, it took a few breaths with its mouth and swam away. Several other fish have also spit out such secretions. I think this white and dark green secretion may be food they don't want to eat, or it may be stomach acid or bad bacteria in water. It seems that it is impossible to explore nature without rich knowledge!

On Friday, March 17, the rain cleared up.

Today, I hung fish food on the hook and stayed in the water for 5 minutes. A greedy little fish swam over. Suddenly, I lifted the hook, and the fish swung its tail at 180 degrees, and its two ventral fins swung back and forth vigorously. Blink of an eye, it jumped 2~4 cm from the horizontal plane, and then fell into the water, stirring up coils of water vortex. I checked the information: Carp (koi fish) does jump, the highest jump is 1 meter. Carps in rivers and lakes often jump out of the water to play at sunset. There is also the legend of "Carp yue longmen" among the people.

Saturday, March 18, the weather is fine.

Today, I want to change water for fish. Before changing the water, the fish were silent, as if afraid of being found, so they "hid" under the water depth of 8~9 cm. Even if there is something delicious, it is "waiting for the rabbit" and waiting for it to sink. But just after changing the water, the fish all shook their fins and chased each other. When feeding, everyone scrambled to eat. Why has it changed so much? Personally, I think: Although carp grew up in rivers and lakes, they are used to living without changing water for a long time. But just as people like clean homes, fish also like clean water. Clean water is not only "fresh air", but also there is no excrement in the pool. Of course the fish like it!

March 19 Sunday sunny to cloudy.

Fish like to play very much! Sometimes they pounce on food, sometimes they hit down, and sometimes they chase and play in the water. However, these are swimming fish. Won't they "walk backwards"? Through observation, my answer is yes. Don't believe me, look at my koi fish. When the little guy swims forward, the ventral fin paddles backward, and the body and tail paddle left and right, creating a vortex to push the fish forward. So sometimes they can slide for a while with the help of the current. When swimming backwards, the ventral fins paddle forward, generating a driving force similar to rowing. In addition, the tail only swings to the right or left, and the fish will naturally "retreat".

I was idle today and saw some snails. I watch them.

Snails have straight tentacles on their heads. Its round eyes seem to grow on straight tentacles. It carries a round and big "house" on its back, and it is printed on the snail's big "house" in a round pattern. It has no legs to bounce around, so it can only crawl forward slowly.

I want all snails to have a crawling competition, only two tiles. Snails have a good sense of direction at first. But after a while, the snail began to move in different directions. A snail climbed to the left and accidentally fell down the steps. I ran down quickly, worried about it: will it die? When I got to the edge of the steps, I saw it naughty and stuck to the edge of the steps. I slowly picked them up, put them in a bottle and put them in a small pool. It was getting late, so we went to bed together.

65438+1Saturday, October 7th Weather: sunny

Today I came to observe snails again. Snails grow up gradually. Last time I saw it, it was as small as the fingernail of middle finger, but now it is as big as the fingernail of thumb.

I organized them to crawl again. I want to see if they have grown up and speeded up. I have observed them for a long time, and I feel that their speed is still so slow. I think the snail may be too hungry to run fast. So I brought enough food-leaves and bread crumbs. Snails crawl slowly and eat slowly, and it takes a long time for food to decrease. It's easy to wait until they are full before getting up slowly.

So I came to a conclusion: the snail grew up, but its speed did not increase.

It is so interesting to observe things around you, so interesting! If you don't believe me, you can experience the fun of observation yourself.
