Observation diary of bean sprouts in the fourth grade

The fourth grade bean sprout observation diary 1 is on! The light outside has dimmed. Tonight, I soak beans with my mother.

My mother and I prepared three different boxes for red beans, mung beans and peanuts.

Start soaking! Because this is my first time soaking beans, I jumped three feet high with excitement. At the same time, I am extremely nervous, because I am afraid that the steps will be chaotic, so that the beans will not germinate and grow well. My hands are shaking all the time because I am nervous. Then my mother showed it to me, and I was not so nervous. I imitated all my mother's tricks very much: clean the box, add more than half a box of water, and in this way, I soaked three kinds of beans. Mother called mung bean "Little Green", red bean "Little Red" and peanut "Little Flower". I said, "No, no! These names are not nice, let me take them! " So I named mung beans "Green Girl", red beans "Miss Hong" and peanuts "Flower Basket". After naming them, we will put them in a cool place.

The next morning, I went to see the beans! Wow! Beans have changed from the size of rice grains to fat! Great! This is the first step of bean germination. It's amazing! When it was time to pour water, I stared at my mother, trying to see the flaw. Mother first punched a few holes in the bottom of the box with a needle, then covered the box with a wet towel, then put the beans on the wet towel, and finally sprayed some water with a watering can, and you're done!

On the third morning, I looked at the bean girls. Wow! Bean girl is cute! At that time, my heart was pounding and I almost fainted with excitement! "Green Girl" and "Miss Hong" have milky white, short and delicate buds on their little heads. The thin buds, like human hair fluttering in the air with the wind, add a little beauty to the bean girl. Let's talk about the "flower basket". She germinates more slowly than the bean girl. The "flower basket" has only small and thick milky white buds on its hair, like some small floral ornaments.

On the fourth morning, all the bean girls in my family grew thin, long and lovely bean sprouts, especially "Green Girl" and "Miss Red". Their long hair is three centimeters long! The "flower baskets" also have long hair, which is beautiful, and the milky white of long hair is a little yellow! I was so happy to find this miracle that I told my parents at once. After listening to this, they were as excited as the first time I soaked beans, jumping three feet high!

On the afternoon of the fourth day, my mother took out my bean sprouts and announced to everyone, "Our little plant has soaked beans, and now it has become bean sprouts." Tonight, let's wait for the chef to fry a plate of delicious bean sprouts! ""good! " "Great", "Great" and "Good idea" Our family all agreed.

I started cooking and frying bean sprouts in the kitchen. I put some oil first, then some salt, and then some chicken essence. I'm too busy!

Eat! We ate my fried bean sprouts with relish and praised my cooking progress! I'm so happy!

Observation Diary of Bean Sprouts, Grade 4, September1July, Saturday sunny.

At half past six in the morning, as soon as I opened my eyes, I forgot to fold the quilt, sat up and put on my slippers in a hurry. I can't wait to run to the kitchen to see the changes of mung beans. Open the gauze covering the mung bean, wow! After a night of soaking, the dolls are bulging, some show white watercress, and grow short and tender roots, just like a girl with pigtails. What will mung beans look like tomorrow? Let's wait and see! September 18

It will be sunny on Sunday, September 18.

"Dad, you come and see! How tall the bean sprouts are! The bean coat has also fallen! " Cheers came from the kitchen. It turns out that my mung bean sprouts are already one centimeter long! The two leaves spread out slightly, like tadpoles. They seem a little crowded in this small bowl. In order to make bean sprouts grow better, we moved them to a flat plate, and the space was much more spacious at once. I wish bean sprouts "healthy growth".

Observation diary of bean sprouts Grade four Grade three Today, I planted some mung bean seeds. I put them in paper cups: first, put a napkin under it, soak it with some water, then put some mung beans on it, cover it with a layer of paper and add some water. Well, the sowing was successful.

Early in the morning, I couldn't wait to open a layer of paper towels on it. Ha ha! I found that the seed coat of mung bean was washed away by water, revealing a little white bud.

65438+1Tuesday, October 3rd Weather: sunny.

Today is the third day, and the white buds have grown up. Their strength is so great that they actually hold up the top layer of paper! I had to remove the top layer of paper that hindered growth. I found that the paper under the mat also became dry and wrinkled, and there was no water. I quickly poured some water to moisten it, hoping that the small bean sprouts would survive.

65438+1weather on Wednesday, October 4th: cloudy.

Ha ha! I found that several bean sprouts have grown very tall, one measure, almost 7 cm. But there are also a few short trees, only 2~3 cm. The tall one has two small green leaves. The color is really fresh and lovely! The short one, without leaves, is a "one-man army" with a big head.

On the fifth day, everyone finally grew two small green leaves. They sucked up the water again, so I quickly poured some more water.

65438+1Friday, October 6th Weather: sunny.

On the sixth day, they grew much taller. The smaller ones begin to grow. All the seed coats have been completely removed, and white fine roots have grown below.

On the seventh day, there were more white fine roots, thicker stems and larger leaves, but the two cotyledons looked smaller and smaller.

65438+ 10 8 Sunday weather: sunny.

On the eighth day, all the cotyledons on the stem have fallen off. The stem grows to about 15 cm. The bean sprouts were too crowded in the cup, so I transplanted them into the flowerpot. I wonder, will they continue to grow?

Observation diary of bean sprouts in grade four Tuesday, September 26th Weather: sunny.

Today, Mr. Wang assigned an assignment: to observe hydroponic mung beans for 7 consecutive days and make records. When I got home, I first soaked mung beans in water. After a while, the skin of mung beans slowly fell off, revealing a small yellow head, and gradually some "unqualified" beans floated up. A few hours later, I emptied the water containing mung beans and unqualified beans, took out an empty flowerpot, put on a wet tissue and put the remaining mung beans in. Mung beans suck water greedily, as if competing with their companions to see who grows taller.

Weather on Thursday, September 28th: sunny.

Nowadays, mung beans have grown a lot. Little white has a little beard on his tail. Bean sprouts are going to grow leaves? I took a closer look and found a small bud in the watercress. So cute! Most of the buds have grown leaves, just like a "green grass". Bean sprouts are one after another, one is taller than the other. I added some mung beans, which stuck out of my green coat and looked around curiously. Not to be outdone, these mung beans continue to grow.

65438+1Monday, October 2nd Weather: sunny.

The tender leaves of mung beans stretch longer and longer, holding up handfuls of green umbrellas. My mother jokingly said to me, "You have raised it so well that you can fire it." When I heard that, of course I couldn't bear it! I picked up the flowerpot and turned and ran away.

Diary of bean sprouts observation: it will be fine on Monday, October 1st, Grade 4.

Today, I went to the vegetable market to buy some mung beans, and I am going to do an experiment to observe the germination of mung beans.

Just bought mung beans, light green, oval. It feels hard and bare. I really doubt that small mung bean sprouts can grow in such a hard body.

I took more than 20 mung beans and poured them into the cup, and put them by the window where I can get the sun, ready to soak them all night.

Look at these cute little beans. I hope they grow up soon.

1It will be sunny on Tuesday, October 2nd.

After a night, I went to see mung beans again. After soaking all night, mung beans turned turquoise. Look at these mung beans. They are half as fat as they just bought. Why? Grandma told me that this is the trace of seeds growing in it, and the seeds will break out of their shells in the future!

I also put the emery cloth soaked in water on the mung bean, so that the water will not be too much or too little, which has a moisturizing effect on the mung bean.

A few hours later, I came to see mung beans again. At first, nothing was found. Later, under my careful exploration, I found this hidden thing. It turns out that there is a small circle at one end of mung bean. I don't know what kind of white this circle is, but it looks like the white on the belly of a fish.

What's in this white dot? What will happen to mung beans next? I fell asleep with questions.

1It will be sunny on Wednesday, October 3rd.

When I woke up from my dream, I hurried to the mung bean. Mung beans are really much bigger, almost as big as children's fingernails, about twice as big as the original! However, I have another surprise: a short line grows in the middle of the white spot of mung bean. I quickly took out the popular science book and knew that it was the root of mung bean, which was used to absorb nutrition and give it to the green leaves. The root color is milky white. It looks like sweet milk. I really want to take a bite. The newly grown stem is only five or six millimeters long, which is not even the width of a finger. How short! The width is even smaller, only one or two millimeters, and the thin one is only as thick as the refill, which looks unremarkable at all. It is very fragile, and it will shake when the breeze blows, making it look like it is going to die, as if someone touches a hair of it and it is killed.

Ah, terrier, grow up quickly and don't be so fragile.

1The weather will be fine on Thursday, October 4th.

Another day. After washing my face and brushing my teeth, I went to see Xiaodouer after breakfast. I took the emery cloth and looked into the cup. Ah, the shell of mung bean is half broken, and small green shoots emerge from it. Small mung beans feel particularly smooth and comfortable, and will grow bean sprouts on them in the future. All these facts show that grandma is right.

In addition, the stem has also grown, from the original short to long, the original five or six millimeters long, two or three millimeters wide roots have also changed. It becomes stronger, showing how fast the roots grow. And there is a small yellow-green sign on the stem head of mung bean. What is this?

……

Yesterday (17 October), mung beans sprouted and grew green leaves. Grandma said, "We can eat mung bean sprouts soon."

Looking at the mung bean sprouts in front of me, I can't help feeling: how wonderful the growth process of plants is! I think as long as we observe carefully, there will be many new discoveries.

The observation diary of bean sprouts is a holiday in the fourth grade, and I am bored to death at home. I suddenly saw mung beans and wanted to do an experiment. Anyway, it's not difficult. The teacher taught me before. So I took out a small amount of mung beans and put them in a container full of water.

The first morning, I took out the soaked mung beans and put them in three jars respectively. I put water in the first jar, only a wet tissue in the second jar, a money tissue in the third jar, and then put the lids of the three jars on the balcony.

The next day, the mung beans in the jar with wet tissue sprouted, the mung beans in the jar with dry tissue sprouted, and the mung beans in the other jar didn't grow anything.

On the third day, the mung bean sprouts in the jar with wet paper towels grew taller, while the mung bean sprouts in the jar with dry paper towels only grew a little taller, and the mung bean sprouts in the jar with water sprouted.

On the fourth day, the mung bean sprouts in the wet tissue jar grew small and tender leaves, so cute!

However, why do the same plants grow at different speeds in three pots? It turns out that this has a lot to do with temperature, humidity and air. Wet tissue mung bean grows fastest, because the temperature and humidity are suitable and the air is sufficient; Mung beans wrapped in dry paper towels grow slowly because they are too dry; Mung beans with water are difficult to germinate because of lack of air.

The experiment of mung bean germination is really interesting, and nature is really wonderful!

Today is the Mid-Autumn Festival and the first day of the National Day holiday. Teacher Mao asked us to observe the growth process of mung bean sprouts.

I grabbed a handful of mung beans and observed them carefully. Mung bean is wearing a green coat. I put it in the water and pay attention to its change. I wrapped the mung bean with soaked gauze.

The next morning, I hurried to see my mung beans. Mung beans are swollen. Compared with yesterday, they are obviously bigger and softer. The skin of mung beans has also blossomed, spitting out a little green shoots.

On the third day, the green bean sprouts grew a lot taller, but today the height is different, as if to see who grows fast. In the past, adzuki beans that absorbed more water would grow faster, while those that grew near the basin would be shorter. Water is their food.

On the fourth day, the mung bean sprouts grew taller and the two leaves unfolded. As the bud grows longer and longer, its color changes slowly, from milky white to lavender to deep purple, and finally two blue leaves appear.

I really learned a lot by planting beans this time.

Diary of bean sprouts observation, grade four, August 23, Friday sunny.

Tonight, I took out more than 20 mung beans according to the teacher's request. These small mung beans are round, and there is a white line on each mung bean. This white line is like a small squint of a small mung bean. I put mung beans in a disposable transparent plastic cup filled with half a glass of water, so that I can observe my little mung beans more clearly! After about two hours, I took a closer look. Look! How interesting! Mung beans got fat one by one and became "green fat managers"! It's strange that the water in the cup gradually turns pale green again!

On Saturday, September 24th, it was cloudy.

The next morning, the first thing I did when I got up was to see how mung beans were soaked in water. Through the cup wall, I found that mung beans have absorbed a lot of water, and the epidermis gradually cracked, revealing buds about two millimeters long, just like the pigtails of mung beans. Some mung beans take off all their clothes, revealing only bare skin; Some only took off half, which made them feel a little shy. I didn't take it off at all, and I don't want to show it to everyone. How cute! At night, the mung bean skin changes from dark green to light green, and many mung bean skins fall off completely, revealing gray beans. One or two of them drank enough water and grew small germs. I am so surprised! What will these little mung beans become tomorrow? I look forward to the early arrival of tomorrow.

It rained lightly on Sunday, September 25th.

This morning, I saw many small germs grow from mung beans and break away from the skin of mung beans. The white line began to disappear. Without separation, the white line gradually deepened. From the water surface, mung bean skins are all on top of mung beans, and there are some small bubbles on the water surface. Smell it with your nose, it smells like mung beans! 1 1 pm, I saw a naughty little mung bean floating on the water. I squeezed the cup with my hand and it sank again, just like a floating doll. How interesting!

Today, I happily put mung beans, mung bean seeds, into a small bowl.

They are oval and turquoise, just like an oval green diamond and a tiny stone with a vertical line in the middle. The vertical line is colored. I'm going to make bean sprouts, so I pour hot water into a bowl filled with mung beans. I found that the mung bean in the bowl changed from green to dark green. While observing, I said: bean sprouts, bean sprouts, grow fast! After observing for a long time, nothing has changed, but I am not discouraged and continue to observe. Mung beans didn't seem to be against me. When I was ready to stand up in frustration, I suddenly remembered that we had learned the story of "pulling out seedlings to encourage growth" and knew that it took time for plants to grow, so I quietly waited for mung beans to soften: the green skirt was wrinkled. It worked. It has changed.

I woke up the next day and immediately went to see my bean sprouts.

Ah! The belly of mung bean became bigger, and the white vertical line of mung bean belly disappeared, and a small bud grew from it. The front of the small bud is sharp and pure white. Some buds are like silver needles, while others are like fishhooks.

I found that mung bean sprouts were too crowded in the bowl and needed to grow in a larger environment, so I found a piece of gauze and poured mung beans into the gauze. I think plants need water to grow, so I immediately picked up some water and sprinkled it on mung beans. I covered mung beans with hay and towels.

I wish the bean sprouts would grow soon.

Monday, today is my third day of sprouting bean sprouts. I ran to the door of the classroom immediately after school, and my heart had already flown to the mung bean. I just went home and put down my schoolbag. I ran in three steps and two steps to see my baby-mung bean sprouts.

I opened the gauze and gently opened the hay. Ah! Their buds grow everywhere, and some are as crooked as earthworms; Some are like axes; Others are like question marks.

The mung bean sprouts seem to be hot, and the clothes are all open, revealing a white belly. But the most important thing is that the buds are 5 mm long, but some are still 5 mm in total.

I covered the mung bean sprouts with hay and put them on the desk.

165438+ October 23rd

I flew home from school on Tuesday, threw away my schoolbag and ran to the baby's house to have a look. Ah! Some bean sprout clothes have fallen off, revealing a yellow and tender body, which is 5 mm long.

Some mung bean sprouts are like swans-mung beans are like swans. The sprouts of mung beans grow very long, and the middle part is a little curved, like the neck of a swan. Top 4 mm, growing forward, like a swan's head. Some are like snakes, winding and can hook a little hay! Some are like ducks combing their feathers.

Looks like my baby is not bad.

Observation diary of bean sprouts in the fourth grade 10 Today, the teacher assigned us a special task-soaking beans. I thought: what beans should I soak? Just soak mung beans. I like mung bean sprouts very much.

To start, I first found a lot of mung beans, brought a red spoon, turned on the tap, took half the water, and then gently put the mung beans into the spoon. I see mung beans are round with a black and white vertical line in the middle. The green shell is smooth, just like a green elf.

Gee, some beans are floating on the water. What happened? I was curious and flicked the beans with my fingers, but they just floated up after falling two or three centimeters, as if dancing; However, some mung beans just "sink into the sea", which is really interesting!

The next morning, after I got up, I couldn't wait to see the beans, but the mung beans were safe and there was no change. In the evening, I went to see it again, and found that some of them had cracked a small crack, and some of them were bulging. I clapped my hands happily and cried, "Great, great, mung beans have finally changed!" " "

I want to create a good growth environment for mung beans, fish them out, put them in a basket, smooth them and cover them with leaves. On second thought: plants need water to grow, and without water they will wither. I spilled water on them.

At noon on the third day, I went to sprinkle water on mung beans and found that mung beans split in two, and a thin white head emerged from the crevasse, with yellow buds in the middle, like tadpoles. I also found that the mung bean that was pressed below can't wait to grow up. You push me and shove me, so lively!

On the fourth night, when I went to the water again, I found that the changes of bean sprouts were really great. I use their infinite "arms" to open the green shell, which is about two centimeters long, like a hook. I watered them carefully and said to myself, "Little babies, you are growing so fast!" "

On the afternoon of the fifth day, I skipped to the bean sprouts. The bean sprouts have changed a lot at this time. On the other side of the bean sprout, there is a "small mouth"-two green leaves with slender roots. They hold their heads high proudly and strive to grow up. Douban is red. It may be cooked soon. It seems that my guess is true. At night, the bean sprouts are really mature, and the longest is eight centimeters.

Mom makes them into delicious food. I ate with relish, and my heart was sweeter than honey!
