During this holiday, I observed the soaking of mung beans in water according to the teacher's request. Early this morning, I picked some mung beans out of the jar, put them in a glass, and filled them with a little water, but they didn't pass. I soaked them in hot water with a dry towel, wrung them out, folded them into a square, and covered them on the mouth of the cup. I "planted" the mung beans with great expectation.

I wish it could sprout quickly! In the evening, I found that the mung bean absorbed water, gradually became bigger, the water became less, and the mung bean became fat, like an inflated ball. Moreover, the color has changed from dark green to light green, some even slightly yellowed, and some have broken their skins to reveal white meat.

This morning I went to see mung beans again, added water to them, and washed the towels. I found that all the mung beans have cracked and sprouted, just like a golden cicada. Its sharp bud is like the tail of a tadpole, and the mung bean after taking off its coat is very similar to the white rice kernel, with a seam in the middle.

I went to see what would happen in the morning again. I was surprised to find that the bean sprouts grew from yesterday's 1 cm to today's 2-3 cm, and the water became less. I thought: if they grow another 4 cm, they will be as long as the bean sprouts sold in the market, and they can be cooked and eaten. After careful observation, I made a new discovery.

It turns out that the crack that broke the bean sprouts has widened, like a flat peach, and it is a little purple, which is amazing! I haven't seen mung beans for three days. Today, I discovered a secret for the first time. Some hairs appeared on the top of the bud, and some Y-shaped leaves grew on the watercress. It's amazing!

Dad said, "I have a friend who keeps a big bag of mung beans in a wooden bucket. His buds are more than ten centimeters long. You have to refuel!" " I will definitely raise mung beans! I didn't expect my little mung beans to change so much after being soaked in clear water-to become a dish on the table.

In the morning, my mother caught some mung beans and put them in a bowl, adding water. At noon, mung beans became bigger and broke the green coat. Mother filtered the water, and we waited quietly for the mung bean to sprout. In the evening, my parents and I came back from shopping in the supermarket and saw that mung beans had begun to sprout.

The tiny bud poked its head out of the mung bean mother's arms playfully to see how wonderful the outside world was. When I got up in the morning, I saw that the bean sprouts had grown, about 1 cm. They broke free from their green coats, revealing their white bellies and dragging their small tails behind them, just like tadpoles. Mother added water to the bowl and the green coat of bean sprouts floated.

Mother filtered out the water and the green coat went out with the water. In the evening, I took a ruler and measured it. The bean sprouts have grown to 2. 4 centimeters. They grow so fast! In the morning, I went to the kitchen to see the baby bean sprouts. They grew again. I took a ruler and measured the root of the baby bean sprouts. The short one is 2.5 cm, the long one is 3.3 cm, and the longest one is 3.4 cm.

Mom said let me take care of the baby bean sprouts, and I said, "Good! "My mother taught me to connect water to the baby's bowl of bean sprouts, and then to filter out the water. After filtering the water, I put the bowl there, picked up a bean sprout and looked at it. Small leaves grew in the middle of the watercress, just like a snake's tongue. In the evening, I scoured the baby bean sprouts and filtered the water.

I found that watercress has changed, some are green, some are purple, and the small leaves in the middle are much longer than in the morning. In the morning, after I got up, I went to see the baby bean sprouts. I found that the baby bean sprouts had tiny roots and long leaves. My mother and I connected the bean sprouts with water, scoured them, and then filtered the water.

Then, put the bean sprouts in order, let the bean sprouts face up and the roots face down, and then pick up some water inside. Mom said that plants have phototaxis, and they all grow in the direction of light. Because our bowl is transparent, my mother found a piece of cloth to cover the periphery of the bowl. At night, the bean sprouts have grown very long, and the longest one has grown to 9 cm.

Their leaves grow out of the watercress, the bottom of their roots are sharper, and the tiny roots are a little longer. Douban is divided into three parts: root, stem and leaf. Douban has turned purple, and the stems are purple.

This afternoon, I'm going to soak some small mung beans for observation. I first poured the dried warm water into the fresh-keeping box, then put a handful of mung beans into the warm water and covered it, leaving only a small hole. Finally, I put it on the sunny windowsill and went out to play with my sister.

After more than an hour, I hurried to the window sill to see how my little peas were doing. I saw beans lying on the bottom of the water, as if they were sleeping babies, so cute. Some beans have become bigger, from small round to square, and other beans have also changed slightly, with a small white spot protruding in the middle.

Unexpectedly, it is incredible that beans have changed so much in just one hour. This morning, as soon as I got up, I ran to the window sill to see what had happened to my "baby mung bean". Oh, I haven't seen it all night. My "baby" has grown up and some peas have begun to peel.

When I changed the water, I found that the water was less and turned green. At this time, I understood that these small beans could also "drink water", and the reason why mung beans "grew up" was also this reason. In the afternoon, when I looked at mung beans again, I found that more mung beans began to peel. I picked up a bean and looked at it. I found that the bean had a "small tail".

I can't tell you how happy I am to find this change. I shook the little peas a few times, and they all turned over. Wow! Almost all mung beans have "tails". Their tails are thin and small, and they are smooth to touch. I am always in an excited state from afternoon to night. I haven't observed my mung beans for a day, and I don't know what happened to them.

I thought, and walked to the window. When I opened the lid, I saw that most of the beans had taken off their green clothes, and the little tails of the baby beans had grown up and turned into pigtails. Time passed by, and in the afternoon, baby bean's braid grew up again. Moreover, baby mung bean's braid was particularly interesting, first straight.

It's long, and the pigtails are slightly bent. If it's longer, the pigtails will all be tilted. That's interesting. A few days later, my mother looked at my soaked beans and told me, "You can eat your soaked beans!" " I listened and laughed. I was so happy that I ate my own bean sprouts that night.
