A few days ago, the teacher gave us an assignment, let us go home to soak beans and observe its growth and change. So, after school, I asked my mother to prepare a full bottle of water for me, and then I found dozens of vitality beans to put into the water, and then I went to do my homework. March 15, change water for soybeans. I found that their bodies became taller and their bellies became thinner. Their lovely appearance is as beautiful as a princess in yellow. /kloc-in March of 0/6, their bodies were covered with many wrinkles and lifeless like white-haired grandfathers. March 17, I changed the water for soybeans again. Their beancurd skin falls off, just like a group of children taking off their clothes and taking a bath. How innocent and lovely they look! On March 18, their "small mouths" cracked. I felt that I was only one step away from success, so I quickly changed their water. On March 19, soybean finally showed its white "small tail" eagerly. Their tails are about 2-3 cm long and look like the chin of an old man with a beard. In the evening, my mother made a delicious dish of bean sprouts with my soaked bean sprouts. I wolfed down the food because it was the result of my own labor!

One morning, the science teacher asked us to go back to soak some beans and observe their growth, which made me very excited. Finally, after school, I hurried home, took a cup, filled it with half a glass of water, and put some soybeans in it. At this time, I really hope to make beans grow up quickly!
19 It rained on Wednesday, June 9th.
Come to the balcony to change water and soybeans as soon as I get home today. I emptied the water in the cup and picked out the soybeans one by one. I found that the skin of soybeans has softened. Wrinkled, like an old woman's face. Moreover, it's like eating a "fattening agent" and gaining weight.
Thursday, June 20, 2009 is cloudy.
In the morning, I go to see soybeans as soon as I get up. Great, soybeans have broken ground. I jumped three feet in excitement. These buds are really varied: some are like shy little girls, hiding; Some are like mighty warriors, holding their heads high; Some are like dancers, dancing gracefully. ...
It is cloudy on Friday, June 2, 2009/KLOC-0.
Small bean sprouts have grown very long, and many roots have grown on the bud tip. Grandpa told me that this is the root of soybean. Now that the soybeans have taken off their clothes, they look fat in vain, very fresh and lovely.
I can't help but respect bean sprouts in my heart. Although they don't have good nutrition and environment, they are still growing unremittingly. I think it is the spirit that our teenagers should have when they grow up.
Last week, the teacher asked us to observe something. I thought about it and finally decided to observe the bean sprouts. I chose five relatively large mung beans and put them in a cup, and I also put water five centimeters deep.
The next morning, I began to observe bean sprouts. I found that the bean babies were so fat and full that they couldn't even button up their green coats, showing their fat bodies in vain. I am very happy, because my green baby is growing up.
A few days later, when I changed the water for bean sprouts, I found many baby beans floating on the water. What happened? Is my bean sprout dead? But dad said the bean sprouts didn't die, but grew up. Hearing this, the big stone in my heart finally fell to the ground. After putting the water in, I thought: since bean sprouts are sunshine, so is sunshine. Will bean sprouts grow better in the sun? When I got home, I saw it, and sure enough! Bean sprouts have "horns" and are stems. I'm so happy!
Saturday is my saddest day. That's because my mother said to me, "If you soak bean sprouts in water now, they won't grow much. You should plant them in the soil. " But I thought to myself: that's not necessarily true. Didn't you see the bean sprouts seller soak them in water? So, I didn't listen to my mother, but I soaked the bean sprouts in the water. When changing the water for bean sprouts at night, I found that the water soaked for a day turned yellow and there was a sour taste. Pinch the bean sprouts again, ah! Rotten! It seems that my bean sprouts are dead.
Hey! I'm so sad!
Today, I observed ants. Although these things are small, they are all Hercules, and elephants are not as strong as them.
This ant looks special. It has two small tentacles on its head and its body is black, like a small cinder. Ants are social animals and can kill caterpillars ten times bigger than them. Once, I put some bread crumbs in an ant's hole. After a while, an ant came and saw the crumbs, but I didn't move them back, but went back to the hole. I am bored. Why didn't I carry them back, but went back? I waited for a while, only to see the ant bring back a large group of ants and carry the bread crumbs back. It turned out that he went to call his companion.
What about my observation? Isn't it great?

Today, as usual, after changing water for snails, I had a whim and put some sand in it to see what would happen. As soon as I sowed the sand, the two snails thought it was snowing, and they jumped there. When I finished sprinkling "snow", two snails realized that it was sand. They wrapped it up and ate the nutrients in the sand. First, they wrapped the small sand with snail meat and then ate it.
Snails are full of food and drink. It's time to show them to everyone. One snail is fixed at the bottom of the bottle, and the other snail is fast. In the blink of an eye, he climbed onto the other person's back and swayed, as if performing acrobatics! It's incredible that this snail actually lifted another snail. Acrobatics is a success!
Yesterday, I found a ladybug at home, so I put it in a plastic bottle. In order to let it breathe fresh air, I pierced several holes in the plastic bottle.
After a while, my father saw the ladybug and asked me, "How many legs does the ladybug have?" ? What does he eat? I have some spots on me. "Dad's question left me no time to answer. But I answered a question I knew first (well, I don't need to say it, I guess everyone guessed it), so I told my father the answer. Dad said, "Everyone knows this. Next, it depends on how you answer. " I said it was simple: "Observe. "So my father gave me a day.
I just finished eating this morning, and I can't wait to observe ladybugs. I found-there seem to be eight ladybugs! But when I look closely, I find that ladybugs have six legs. If I had told my father this discovery in advance, he would not have laughed off his fangs. Then I found the page about insects in the Animal Encyclopedia, only to find that Ladybug septempunctata is a famous natural enemy of pests. Adults can prey on wheat aphids, cotton aphids, locust aphids, peach aphids, scale insects, ticks and other pests, and can greatly reduce the harm of trees, fruits and various crops to pests, so they are called "live pesticides". My father looked at my findings and said, "Well done, son.
By the way, do you know what I said that I answered first? Ha ha! ! ! It's that ladybugs have several spots. The correct answer is seven. Did you guess right?
One day, I had a whim to see how frogs eat insects. In summer, I came to the pond, grabbed a glass bottle and snapped. A frog the size of a fist is easy to catch. I had a hard time catching a small fly and putting it in the bottle.
After a minute, the frog rolled his big round eyes. After a long time, he suddenly stretched out his "super long tongue" of about two or three centimeters to hook the fly. The fly is dying, and the frog retracts its long tongue, but it seems dissatisfied and wants to jump out. So, I used a small biscuit to lure the fly into the frog's mouth. In the blink of an eye, the frog suddenly caught two or three flies and ate them, and the rest of the flies were also eaten. This time, the frog was satisfied I finally observed how frogs eat worms!
Observation composition 8 Today there is a once-in-a-century "total solar eclipse" spectacle. My parents and I got up early, but the weather was not beautiful. The sky was gray and the sun was looming. Will it affect our observation?
I have butterflies in my stomach. Dad turned on the TV and saw that the "News Channel" was broadcasting the latest situation of the total solar eclipse nationwide. The host introduced the knowledge about the total solar eclipse, which made me understand "first loss, food, food, light, last contact;" And corona beads and Bailey beads. The sun in Guang 'an, Sichuan Province, which was shown on TV, slowly left only one line, and Yixian, Chongqing was in darkness. My parents and I can't wait to come to the seaside park. I saw many exciting things in the seaside park. Some people are expecting, some are talking, and some are waiting silently. I looked up and saw "Tiangou" eating the sun bite by bite. The sun is covered by clouds for a while, and then exposed, just like a shy bride. Ah! The sun turned into a crescent moon. Ah! There is only one line left in the sun. Ah! The moon completely obscured the sun. The people around you screamed loudly, and it was dark all around. Then the street lamps, floor lamps and neon lights in the park all lit up.
It lit up bit by bit, and I quickly put on my "filter glasses". Wow! How beautiful these Bailey beads are! I was intoxicated by this magical sight. Slowly, slowly, the moon left the sun and the light returned to the earth. Nature is magical and spectacular! The mysteries of nature are endless! I love nature!
Observation composition 9 Today, after school, my classmates gave me a snail. I am very happy! Later, grandpa also gave me a snail. I'm excited and happy!
When you get home, soak the snail in the water. But it wasn't long before the snail showed its head. I was very happy at that time, so I took out the paper and let the snail climb up. The snail just climbed a little and stopped climbing. I thought it was strange, so I put it in the water for a while and then let it climb. However, it stopped crawling, and I was disappointed. Suddenly, my father came and he wouldn't let me keep it. I didn't. So, I put it aside and left it alone.
If only dad would let me keep it.
I have a small room of my own, about 12 square meters. The walls and furniture inside are pink, and some furniture has a heart-shaped pattern.
I remember a sunny Saturday morning when the autumn wind was blowing gently. I'm doing my homework in my room and I'm a little tired. I just looked out of the window and wanted to have a rest. Suddenly, I looked back. Why did my pink wall turn white? I quickly sent someone to ask my sister: "Sister! Why has my wall turned white? " My sister said slowly, "Because the sun shines on the wall and the light is reflected, your wall becomes white." I finally understand that light can be reflected! At noon, my sister and I went to my room to do our homework after dinner. I found my wall turned pink again. "I know this is because the sun went down, so it turned into the original color." I said. My sister gave me a thumbs-up and said, "You are so smart!"
I must read more extracurricular books in the future, or I will make jokes again.
Observe the composition 1 1 In today's composition class, the teacher gave us a small experiment.
The teacher asked two students to bring two cups of boiling water first, and we were puzzled. The teacher put two cups of boiling water on the table, picked up one and took a sip. Then the teacher took out a box of paper clips and said, "Guess, how many paper clips can I put in the water to fill the cup?" As soon as the teacher finished speaking, the students began to make noise. Some students said they could put three or four pieces, and some students said they could put 100 pieces ... I thought to myself, "Paper clips have a certain weight and can only put seven or eight pieces."
The experiment began. The teacher put a paper clip in, but the water didn't come out Then he put the second, third and fourth paper clips ... the number of paper clips is two-thirds of that of the cup. I'm confused. A small glass of water can hold 158 paper clips, which is beyond my imagination. It's incredible!
The teacher finally announced the answer. It turns out that the water has tension, the mouth of the cup is curved, and the size of the paper clip is also very small, so the cup can hold 158 paper clips. I suddenly realized that a small glass of water has such a big mystery!

This is the first time I have opened the curtains so early. It's too quiet outside. There is no one in the opposite window, and there are no birds flying outside the window. Nothing happened on the park tower in the distance. I see the shadow of a house in the west. I really want to shout and break the silence!

The back of the rain
Some people will ask why the rain has a back. The back of the rain is very ordinary. Clouds are the back of rain. The cat that hides from the rain jumps in the rain, and the cat's back is the back of the rain. The umbrella against the rain is the back of the rain. At night, the moving car illuminates the wall, and there are moving light and shadow on the wall, which is also the shadow of rain.

Appear green shoots
Our big aloe has sprouted green buds. Small shoots emerged against the background of the soil, soft and tender, with a feeling of green inside and white outside, white inside and white inside, clear and transparent.
There is an ant hole under the big tree in front of my house. There are many ants in the hole. I often watch them move things.
Today, I saw an ant find a stiff dragonfly far away from the hole. I want to know how ants move things bigger than themselves, so I observed them carefully.
Only the ant touched the dragonfly and hurried home. I followed it carefully. After a while, many ants appeared in front of the dragonfly. They bumped into each other as if discussing ways. I stared at them unblinkingly, only to see that the dragonfly was quickly chopped into pieces, and then they moved it back to the hole bit by bit.
I am dumbfounded! "Unity is strength"! Small ants all know this truth, let alone us?
On Saturday afternoon, I played on the playground. Suddenly, I found a string of little black things moving in front of me. I'll go quietly and have a look. Oh, it's a group of little ants moving! I squatted down to observe carefully.
How interesting it is for ants to move! You see, some of them have ants' eggs, some have newborn ants, and some may have moved their things to new houses, and then the procession of carrying them is always neat. Suddenly, an ant found a caterpillar beside their team. He saw it run to tell its companion. Soon, the dragon-like team rushed at the caterpillar. They bit the caterpillar with sharp teeth, making it writhe painfully, and killed several big ants at the same time. The ants didn't believe it, so they came up with several more. After about 20 minutes, the caterpillar was taken home by the ants, motionless.
It turns out that ants know how to unite.
I have some small snails. They are very cute. They have hard shells, like "soldiers" in battle, hard "shields", they are soft all over, and they have bright eyes. Where they climbed, they left a lot of liquid. As long as the sun shines, it will shine brightly and leave traces.
I took a look and found that snails crawl very slowly. I go online to find information. It turns out that it has no feet. When a snail crawls, it clings to other objects with its abdominal feet, and it can crawl slowly by its abdominal muscles. And it has a "hill" on its back, so its crawling speed is very slow. Snails like Chinese cabbage. It is a pest, and it has many teeth. Science shows that it has about 20,000 teeth, which are invisible to the naked eye. If you put it into the cardboard in time, it will bite it open and climb out soon.
This is my snail.
