Observation diary of bean sprouts growth process 500 words 1 One day in September, the teacher asked us to go home to cultivate mung bean sprouts and observe their growth process. When I got home, I took out two or three mung beans and put them in a transparent cup. There is a paper towel under the cup, and mung beans are placed on the paper towel. Put mung beans where we can see them, so that we can observe the growth process of mung beans.

Look, there are some mung beans lying quietly in the cup now. Mung beans are green, only half the length of nails, oval, and look like a fat doll. If you smell it carefully, you will smell the fragrance of mung beans.

The next day, I can't wait to see my little mung bean. Ah! My little mung beans have sprouted, some have taken off that old dress, some seem to like that green dress very much, and they are still wrapped tightly.

On the third day, mung beans grew green leaves and the stems were two or three centimeters long. Don't underestimate the strength of these stalks. They lifted all the paper towels that covered their bodies, which was a bit naughty. They wanted to get some air, so they grew up outside the paper towels.

On the fourth day, the mung bean sprouts were about seventy centimeters long, and each mung bean sprout bent down like an old man. The roots of mung bean sprouts are khaki, and the stems are white. The breeze blows the mung bean sprouts and shakes them from side to side, as if to greet us.

On the fifth day, some stems of mung beans are more than ten centimeters, some are faster than twenty centimeters, and some leaves have mung bean shells.

On the sixth day, mung beans have completely germinated, the longest is three centimeters, and the shortest is only twenty centimeters. Some unknown flying insects will appear in the cup from time to time.

After I came home from school today, I immediately soaked mung beans in water. Small mung beans are hard, all covered with green coats, and only one side has concave white spots. I think this is the place to sprout.

September thirtieth.

When I got up in the morning, I ran to get the bottle of mung beans and observed it carefully. I saw some mung beans have taken off their green coats and exposed white meat. Some mung beans want to take off their coats but can't. I seem to feel that they can't wait to take off their coats. There are still some mung beans that have not moved. I shook the bottles, and they were still the same. So I stopped looking at them.

Today, my family will go back to my hometown to visit my grandfather. I didn't forget to bring my partner-mung bean. After a long journey of several hours, I finally arrived at my grandfather's house. I immediately took out the bottle of mung beans and found that all the green coats of mung beans had been taken off. I shook the bottle, and its green coat floated beautifully in the water. I looked at it carefully and found that a few beans sprouted little by little and grew in the "small holes" that turned white. You can't tell without careful observation. I added some mountain spring water to the bottle, and then put the bottle in the water tank to let the mung beans bask in the sun.

Nowadays, almost every mung bean has a small bud. The longer bud is almost one centimeter long, and the shortest bud is three millimeters long. Germinated mung beans dance in the water like small commas. I think they grow very slowly. It took several days to grow that long. So I poured the original water and changed it for them again, hoping that they would grow up quickly after absorbing nutrition.

Two days ago, I planted an onion, but unfortunately the root was soaked. The long bud still didn't move, so I let it touch the fried meat. I can't grow onions, but raw bean sprouts, I think I am still handy. So my bean sprout fight started today.

Yesterday, my mother bought me mung bean seeds. I soaked it hopefully, expecting it to sprout. Today, as soon as I got home from school, I rushed at my little bean, but when I opened the lid, I found that the little bean stinked, so I shouted to my mother, "Mom, why does this water stink?" Must it be like an onion? "But mom said," That's because the beans have been soaked in water for a long time, and the fermented taste won't go bad. "Go and change the water." Oh, I see. I flew into the kitchen at the speed of an arrow and changed a glass of water for adzuki bean. After the change, I saw that the green beans were full and ready to crack. I smiled and said to the little bean: Rome was not built in a day, and beans can't grow into bean sprouts in a day. Don't worry, your season will come.

Two days later.

Mom, mom, my little bean sprouts successfully took off their green coats and showed their yellow bellies. "Yes, that little mung bean has successfully performed a golden cicada for me. Is it possible to eat my bean sprouts after today? I was just thinking about it, and suddenly I found that the house for small bean sprouts could not hold it. Had to replace its original home cup with a big iron basin.

A week later.

Wow, it smells good. "The moment I sat at the dinner table, I couldn't wait to pick up the bean sprouts and found the small bean sprouts lying on the plate like tadpoles. I looked at each one carefully, and some of them looked like the number 9. I put a bean sprout in my mouth, and there was a smug smile on my face.

On Saturday, the composition teacher said, "Let's soak mung beans." When I got home, I carefully selected a few intact mung beans and put them in a bowl, then poured some water in. Then, I took a piece of cloth and covered it on the mung bean like a warm quilt. I read that covering with wet cloth will raise the temperature and germinate quickly. I wonder if such a small bean can sprout as if it were asleep.

I got up early today to see my little bean sprouts. I ran to the balcony and looked, wow! The beans are peeling, like children, and they all take off their thick coats when it is hot. It used to be green skin, but now it has become a white belly. I want to jump for joy.

I went to see my little bean sprouts again today. They grow small buds, just like tadpoles with small tails. When I changed water for them, I found that the original clear water turned into green water. I am very happy.

Today, the teacher gave us an assignment to observe the growth process of mung beans.

I selected some excellent round mung beans, put them in a transparent plastic cup, and put a little water in the cup, just a little higher than mung beans.

I will put the mung bean cup on the balcony to observe.

I think it would be great if mung beans could grow up immediately.

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

I began to observe mung beans again. I used to water them every day to make them absorb water and grow rapidly.

Today, I observed mung beans, and found that with a "wow", mung beans swelled up and broke all the "green clothes", and some of them only took off half of the "green clothes". They also split a small mouth in the middle, split in two, and grew a long beard in the middle. The green leaves growing in the middle are like a pair of "small scissors".

I also found that some beans were rotten and I had to throw them away, because my mother told me that the natural law "survival of the fittest" means that the excellent ones survive and continue to grow, and the inferior ones perish.

I saw mung beans today. Wow, the leaves of mung beans are getting longer. Its cracked fruit is like two boats, its leaves are like two beards, and its bright green leaves are flat.

Among them, the "height" is up to eight centimeters, and the smallest one germinates.

Mung bean itself contains vitamin C, but when it grows into mung bean sprouts, its nutritional effect will be 7 times that of mung bean itself.

How I wish mung bean sprouts could grow taller than me tomorrow.

Diary of observation on the growth process of bean sprouts 500 words 6101it's sunny on Friday, October 25th.

I soaked several beans last Sunday, including red beans, mung beans and soybeans.

As soon as the beans were soaked, I went to see them soon. I see them five or six times an hour. My mother smiled and said, "Where is it so fast?" Before going to bed at night, I was surprised to find that mung beans and soybeans seemed to get bigger and went to bed contentedly.

The next day after school, I rushed into the house to see my beans. Wow, the skin of soybeans is wrinkled, like waves, and very soft. Several other beans have also become bigger. I jumped up and down happily and asked my grandfather, "When will these beans sprout?" I can't wait! " Grandpa smiled and said, "These beans are growing well and should sprout soon." "I am very happy after listening to it and look forward to the day when the beans germinate.

Another day passed, and the day when the small beans germinated finally arrived! I excitedly ran to the windowsill and saw mung beans and soybeans peeling outside, revealing white "skinned" beans with needle-like short and hard buds. The bud is very close to the bean, so it can't be opened without effort, just like mother and son.

Two days later, only red beans have not germinated. The skin of adzuki bean is cracked, and it seems that there is also a crack between mung bean and soybean. It needs to be handled carefully, and once it is destroyed, it will not grow again. The buds have separated from the beans, as if the beans were about to be split in half. I'm particularly excited. I think my dream of cute little beans has finally come true today. I looked around excitedly with the jar.

Witnessed the growth process of bean sprouts, experienced the pleasure of observation, and loved this unknown world even more!

I like bean sprouts very much, but the rootless bean sprouts sold in the market are said to have been soaked with herbicides. My grandfather said that they could not be eaten, so he decided to make them with me.

It happened to be Sunday. Grandpa and I turned on the computer, looked up the data of bean sprouts, and prepared utensils and materials according to the requirements of the data. In order to let me practice more, grandpa did all the operations, and he kept by my side to check for me.

I found an empty coke bottle, cut off the conical part of the bottle mouth, and then drilled a hole in the bottom of the bottle with red-hot iron wire. Then I poured the mung beans soaked for a day and a night into the bottle and covered them with wet towels. The first step is completed.

The second step is cultivation. After a few days, most of the beans have germinated, so we have to carefully select and throw away the beans that have not germinated. I asked, "Grandpa, why don't some beans sprout?" Grandpa said, "They are not ready. Isn't there a saying like this? Success belongs to those who are prepared. " Grandpa is really good at communication and play. After a few days, their roots come out of the bottle hole and have to be cut off with scissors. Their buds are growing slowly, and they need to find something heavy to press on them. So I have another question to ask grandpa. Grandpa said, "I know why you have more children." Their roots grow harder and harder. This effort is right, but the direction is wrong, so we have to cut them. " Their buds are working hard and in the right direction, but they are a little too much. They have to suppress their impetuous and frivolous, and make themselves stronger and calmer. "I know, grandpa is talking about me.

Seven days later, it happened to be a Sunday, and the bean sprouts grew up. Looking at the white, tender and strong bean sprouts I cultivated, I am happy for their growth, because I have grown up.

The shell of mung bean is already very soft. There is a crack in the mung bean head and a bud grows. How strange! Ordinary food has no tail, but it has a long tail. Is it a lie? Shouldn't it? I lied. I think my nose is getting longer! Little mung beans have buds on their heads, ah! It's amazing that mung beans germinate at such a young age.

The bud of mung bean grows in the crack of the shell, and the bud on the head of bean sprout has grown by almost one centimeter. Mung beans are round at the bottom and sharp at the bottom one centimeter. The middle of the place is bent, the buds on the head are crooked, and the bean sprouts are milky white.

When I got home, I couldn't wait to open the cloth covering the mung bean sprouts and found that the little mung bean had a new change.

The top of bean sprouts is pointed and the bottom is round. The mung bean head has grown to almost two centimeters. It used to be straight, but now it is curved. Bean sprouts are milky white.

Tonight, my father and I selected some good soybeans, put them in a glass jar, and poured some water. The water was just less than half of the soybeans. I asked my father, "What soybeans can germinate?" "Big, full, good germination without breaking the skin." Dad said. I broke the casserole and finally asked, "Why is it that the skin doesn't break?" Isn't it easier for buds to grow without the hindrance of skin? "Dad explained," For beans with broken skin or no skin, the growth environment of buds will be destroyed, and bean sprouts will not grow. "

September 18

As soon as I got up this morning, I ran to the balcony to see how my soybeans were growing. I have an unsweetened soybean in my hand for comparison. I cried in surprise when I saw the soybeans in the glass jar. It turned out that they drank water all night and became twice as big as before. Soybeans that have not been soaked are small, nearly spherical in shape and light in color; Soaked soybeans are oval and yellow. Grandma said to me: wash soybeans once a day before germination, and change the water at the same time, and put them in a sunny place. I changed the water for the soybeans and put it on the balcony.

September 65438, 2009

After dinner at noon today, I went to the balcony to see if my soybeans had sprouted. As soon as I saw it, some soybeans became smaller. I think it should be that the buds have absorbed nutrients and are ready to break the skin and grow out! Some colors have faded, and some skins have broken and sprouted. I emptied the water in the glass jar, replaced it with fresh water, and found a piece of gauze with soybeans soaked in it.

I put mung beans in a bowl filled with water and soaked them for 20 hours. When I looked over, I was surprised to find that the mung bean burst its green coat and showed its white belly. Some grow very fast, and they will grow small buds, like tadpoles. Then I moved them to my "new home"-a small basket. I hope they have a sweet night and a sweet dream in their new home.

Today is the third day, because the roots of small bean sprouts grow very long and come out of the gap in the basket, so I put a solid pot under the small basket. In order to prevent the sun from exposure, I also covered the small basket with a thin gauze. At the same time, I also found that mung bean sprouts have grown. The short one is 3 cm long and the long one is 5 cm long, like a little cockroach with a tail. The tail changed from light green to white again. I really hope that little mung beans can grow up quickly and become real bean sprouts!

Today, the teacher asked us to go home to grow soybeans and keep an observation diary. As soon as I got home from school, I asked my grandmother for 1 1 soybeans. I was shocked when I saw the soybean. This is completely different from the soybean I usually eat. It is only half the size of cooked soybeans, and it is yellow. I touched it, ah! It's really hard, like pebbles. Can this thing sprout? I found a small fish tank with a grain of salt, poured about a centimeter of water into it, and then put all 1 1 soybeans in it.

Saturday sunny

Early in the morning, I began to observe soybeans. Wow! Soybeans are getting bigger, and there is less water in the small fish tank. Soybeans gain weight in vain, just like fat dolls. Oh, some fat dolls drink too much water. Look, the yellow coats they are wearing are too small! They all burst the "yellow coat". I poured a little more water in the small fish tank and said to myself, "Fat doll, sprout quickly!" "

I immediately carefully changed the water for the soybeans and picked up the remaining beans with a cotton swab.

These days, soybeans keep sprouting, and the longer they grow, the higher they get. But today, I found five or six small horns on the tops of several soybean sprouts, which are long and thin. Is this a surprise or a shock?

"Mom, come and see, mung beans have changed! The bean sprouts are growing! " As soon as I entered the room at night, Yaoyao excitedly took me to see the bean sprouts. "Mom, I want to measure the length of bean sprouts with a ruler, but bean sprouts are all curved and difficult to measure." Yaoyao shook his ruler and asked me.

"Then make a rough estimate according to the scale of the ruler." I compared the ruler on the bean sprouts. "Look, how long is it?" "Some of them are about 1 cm," he said, looking at the ruler and bean sprouts from a distance. "Others are less than 1 cm. Oh, look at this, I'm sure it's almost 2 cm.
