Observing the essay, I don t know how to write about 300 words

Check it out for yourself. It's very simple.

On September 26, I soaked 10 mung beans. At night, they were like well-fed children, with a big belly, and they were so swollen that they seemed to crack, and I fell asleep with anxiety.

On the night of September 27, there was finally movement, and some beans took off their green shirts, revealing their big white bellies, as if to say, "Don't give me any more food!" My stomach is about to burst! ”

At noon on September 28, the water was muddy, and I hurriedly went to change the water. After changing the water, I was pleasantly surprised to find that their white bellies were "cracked". Expose 2 mm shoots.

On September 30th, in the morning, alas, why didn't a bean move today? Well, it also smells. It turned out that the green.

Dou followed Tang Seng and his apprentices to "go to the west to learn scriptures"! o( o (Going to the west so soon?) ）

On October 2, there were only 9 beans left. I smelled it, why does it still smell? Yes! Forgot to change the water! After changing the water, I measured it with a ruler, 19 mm!

After a few days, the beans have grown and you can eat fried bean sprouts.

Through this observation, I learned about the growth pattern of beans and felt the joy of observation. o( v )o (Great!) ）

I have a mimosa at home.

As soon as I touch the leaf of the mimosa, it closes automatically, as if to say, "Little master." Don't touch me, I'm shy.

As soon as I saw the mimosa in the dirt dry, I would pick up the kettle and let him drink it immediately. Each time the mimosa would shake its green leaves, as if to say to me, "Thank you, little master."

When I look at Mimosa, I always think she's so cute, so delicate.

One night, when I was about to go to bed after eating, I saw the leaves of the mimosa close, and I was shocked that I hadn't touched him! I decided to find out on my own.

I searched for many books and finally found the answer. It turns out that mimosa, like us, needs to sleep, and when we sleep, we put the leaves together. The leaves are open when you go to sleep.

Sunflowers.

There are many kinds of flowers in the world, such as: magnolia, moon flower, rose, plum blossom, chrysanthemum, junzi orchid, camellia and so on. However, the flower with the most flowers and the most abundant colors is the sunflower.

As the saying goes: "Good flowers don't bloom often". Sunflowers are also good flowers, with red, yellow, white, purple, crimson, orange ......The petals of the sunflower are single-layered, shaped like plum blossoms, with red and black filaments with yellow dots on the core.

The stems of sunflowers are long, thin, soft, and curved. Its branches are thin, the leaves are dense, and the flowers are quite numerous.

Sunflowers bloom only when they see the sun, and every day when the sun rises slowly in the east, the sunflowers scramble to open their smiling faces. When the breeze blows, Sunflower "shakes its head" and seems to be reciting poetry, and seems to nod to pedestrians. The bones of the sunflower are red and the size of a soybean.

Unlike other flower bones, they are short and round.

The flower seeds of the sunflower are surrounded by a few small leaves. The flower seeds are as big as sesame seeds, and when the small flower seeds are ripe, they are scattered in the arms of the grandfather of the earth, and after being moistened by the sun and rain, they can grow and bloom more beautiful sun flowers in the second year.

The vitality of the sunflower is very strong, she sucks the nectar given to her by Grandma Blue Sky to her heart's content, and she greedily absorbs the nutrients of Grandpa Earth. Sunflower thrives under the care of Grandpa Earth and Grandma Lantian, dressing up the motherland more beautifully and adding to the beautiful nature.

At night, the sun is like a child after a day of play, tired and relieved to fall asleep.

Trumpet flowers are also good flowers, it blooms early and loses late, it and sunflowers seem to be a pair of good sisters, they agree to open together, enter sweet dreams together, never bloom early, fail early, and decorate this beautiful nature together. They give themselves selflessly and never ask for anything in return from the motherland or from the people.

Although the sunflower does not have the nobility of roses, the fragrance of chrysanthemums, the purity and elegance of magnolias, and the fragrance of plum blossoms, sunflowers have the spirit of selfless dedication.

I love the sunflower, its tenacious and vigorous vitality, and I love its selfless dedication.

Observe the plant cactus.

There is a strange plant in my house, and its name is cactus. Do you know where the name of the cactus comes from? Let me tell you: because it resembles the palm of a human hand, people call it a cactus!

When the cactus first grows, it is green, and its body is covered with many small thorns, and those thorns are very soft to the touch, and when a breeze blows, the thorns of the cactus dance with the wind, which is very beautiful!

After a while, the cactus turned emerald green, and that green made people look so dazzling, so comfortable, so fresh. The small soft thorns on its body have also become hard, like steel needles. After some time, another flower bone grew on it.

Slowly, it grew bigger and bigger, and finally a big red flower bloomed, which looked so beautiful! According to my grandmother, it is not easy to see cacti bloom, because cacti only bloom once in many years.

The cactus is not very pretty, but every piece of its body is a treasure!

Plants - Daffodils.

When I was a child, I lived at my grandmother's house. At that time, there were many beautiful flowers in my grandmother's yard. In spring, there are spring flowers and peony flowers; In summer, there are sunflowers, crab claw lotus; In autumn there are chrysanthemums and bunches of red, and in summer there are plum blossoms and daffodils.

Among them, I like daffodils the most, I like its appearance, and I like its "heart" even more. Although it is not as delicate as the peony flower, not as red as the sunflower, not as eye-catching as the chrysanthemum, and not as fragrant and intoxicating as the plum blossom. But the daffodils are slim, and the daffodils are clean and clear.

There's an even bigger reason: "Daffodils have a tenacious vitality." ”

Daffodils are known as the "Limbo Fairy". Indeed, its moving posture makes people fall in love at first sight.

Grandma's pots of daffodils are beautiful.

In January, the daffodils are blooming! Its emerald green leaves are emerald green, green and shining, green is bright, criss-crossing between the green leaves, there are a few white and flawless small flowers scattered and scattered, and the flowers are embedded with a **-like stamens, exuding bursts of faint fragrance, which is particularly elegant. Daffodils have nothing to do with soil, and rain flower stone is its "soil".

I thought: I want to be pure and white in my mind like it, without a bit of sludge. The roots of daffodils are like a big onion, and there are white roots under the roots, and they are like long earthworms around the hard rain stones, and they look very stubborn.

A gust of wind blows, Xiaohua shakes its head, swings its soft body, and seems to be dancing on the water stone in crystal clothes, which makes people feel relaxed and happy.

In winter, many flowers can't withstand the ravages of the cold and the test of fate - they wither. The daffodil, on the other hand, is not afraid, when it is cold and snowy outside, it stands proudly, still so energetic and full of life, as if fighting against the cold wind, so persevering, that people love it more and more.

I love Narcissus! Love its beauty and fragrance, love its nobility and purity, and love its tenacity and perseverance!

The world gahay1626 is the biggest on um.

Days, we did an experiment with the teacher. Here's how the trial went:

We prepared glasses, toothpicks, soap, sugar cubes and other tools. We first fill the glass with water, then put in a sugar cube, and finally put a toothpick in it and place it far away from the sugar cube. After a while, something strange happened:

The toothpick actually floated towards the sugar cube, and then stopped on top of the sugar cube. We changed another glass of water, put a bar of soap in the water, and put the toothpick in the water farther away from the soap, and the strange thing happened again: the toothpick was getting farther and farther away from the soap.

Why is that? The teacher told us to think of the answer by ourselves, but my classmates and I only said half of it, and the answer was incomplete, and we couldn't figure it out, so we had to wait for the teacher to tell us the correct answer. The teacher said:

Since you want to know the right answer, I'll tell you. There's science here. The teacher paused and said:

The difference is because when you put the sugar cube in the water, the sugar cube will absorb some of the water, so there will be a small amount of water flowing towards the sugar cube, and the toothpick will float over with the flow of water. But when you put the soap in the water, the tension on the surface of the water will be stronger, and the toothpick will be pushed outward, and the toothpick will float farther and farther. ”

After listening to the teacher's words, we suddenly realized: it turns out that such a small experiment has such a big knowledge, and we must observe more in the future, think carefully, and not just think about playing!

When I was a kid, I used to play downstairs.

I remember that time, the sky was suddenly covered with dark clouds, the cold wind was blowing, and my little hands were cold and cold, and it was very uncomfortable. Seeing that the downpour was coming, I crouched on the ground as if nothing had happened. Actually, I'm looking at the ants closely.

I scratched my little head with my hand. "Huh! Why are there so many ants?

It's strange, what is it that they carry on their backs? Curious, I touched one of the ants with my little hand, and as soon as I got it, the ant fled in panic, giggling with joy and thinking to myself, "What a coward, haha"!

In fact, my heart was deeply attracted by this group of ants.

Bang. Boom", the thunder was very harsh, the sky became darker and darker, the group of ants ran more and more quickly, and suddenly there was a thunder, which frightened me to the core, but I still persevered and wanted to see what was going on.

I crouched there and watched intently, frozen technetium sneezing, and the image of ants moving kept coming to my mind. Isn't it true that I suddenly thought of people hurrying home when it was about to rain? I'm glad because I thought of it after all.

But when you think about it, what is it on its back? I'll have to look at it further. At this time, my mother ran to me, picked me up, and said as she walked upstairs

Oops, what are you doing! Don't see it's raining soon? Still crouching there in a daze, fool" I hurriedly defended myself.

I wasn't in a daze, I knew it was going to rain, so I went to observe the ants! "After that, I didn't forget to sneak a look.

Take a look at your mother to see if she's angry. The mother squatted down and said softly, "My child knows how to observe," and I asked again

Something that ants carry before it rains. What is it?

My mother brought me thicker clothes, told me to change them, and said, "Son, they carry food!" Because of the rain, it is difficult to find food, and that small hole is the nest, and they are moving food into it.

..Don't do such a stupid thing next time! It dawned on me:

Wow! I see! ”

I didn't expect the little ants to learn how to move!
