As soon as I got home, the first thing I did was rummage for mung bean seeds. The method of planting mung beans is very simple: first, put the paper towel in a plastic cup. Second, sprinkle mung bean seeds on it and drop a few drops of water, not too much, just enough to soak the beans thoroughly. Because no matter what plants need sunshine, water and air. So I put it in the most suitable place on the balcony. My "work" has been completed, and all that remains is careful care and waiting.
When I came home the next day, I saw mung bean showing its white fat body and a small root sticking out quietly on its head. I'm so happy. When did this little root grow? It must be shy and doesn't want us to see it. It appeared quietly and vigorously at night.
Two days, to see my baby, yeah! The buds are all three or four centimeters long, white and tender, and they can definitely squeeze out water. It's a miracle to grow such a long bud in such a short time! I asked my mother curiously, "How do mung bean sprouts grow so fast?" Mother said, "You take good care of it, water it every day and look at it every day. In addition, the temperature is very good these two days, which is very suitable for its growth. Happy and comfortable, of course, growing fast. " My mother's witty words made my heart happy. I can't help it if mung bean sprouts grow so fast!
Two days later, I found that the new shoots of mung beans were not white and tender, but thick and strong, and some small green leaves grew, just like adults. The swollen mung bean has been completely emptied from the body, leaving only the mung bean skin, and the root under the skin is tightly pulling the tissue. A closer look shows that the root has penetrated the tissue. All the mung beans I planted before only sprouted and said goodbye. I have never seen them thrive in plastic cups, let alone how happy I am.
From a small mung bean seed to a leafy mung bean, they are like warriors fighting, breaking through the enemy's barrage, going forward bravely, being unknown and working hard. We really should learn from their spirit!

Experience of planting mung beans
Mung beans, as everyone knows, have everything, such as mung bean soup and mung bean porridge. ...
But we seldom hear about "planting mung beans", because mung beans are usually eaten as meals and are rarely planted.
Under the guidance of our teacher, the experiment of "planting mung beans" was carried out smoothly in our fifth grade. We water mung beans every day and change paper towels, so that our mung beans grow quickly and grow into long stems. The mung beans we grow grow fast, but they are very thin. Why?
With this problem, we conducted an experiment: planting mung beans again. This "planting mung beans" is different from the past, because we only planted them in the past, and this time it is the kind with a purpose.
We use the same materials for planting mung beans this time, but the environment in which mung beans grow is different. The record of our experiment is that one group of mung beans is named "experimental group" and the other group is named "control group". The humidity, sunshine and temperature of the "experimental group" are suitable; The "control group" only has water and temperature. Then plant them for a week and observe their changes. Finally, the mung beans in the "experimental group" grow fast and well; The mung bean in the "control group" grows slowly and poorly. Through this experiment, we come to the conclusion that the germination of mung bean seeds must need sunshine.
We come to the conclusion that water, temperature and sunlight are necessary conditions for mung bean seed germination. If there is no water, the seeds will not germinate; If there is no suitable temperature, seeds cannot germinate; If there is no sunshine, the seeds will grow very thin and may die halfway.

Today, the science teacher assigned us a task, that is, planting mung beans. We want to plant two groups of mung beans, one is called "experimental group" and the other is called "control group". Two groups of mung beans were planted for four days respectively, and their growth and changes were observed. The mung bean in the "experimental group" has suitable moisture, sufficient sunshine and suitable temperature, while the mung bean in the "control group" has only suitable moisture and temperature, but insufficient sunshine. They should cover the box and observe for a few days. There are four mung beans in the "experimental group" and "control group" respectively.

Today is the second day. All three mung beans in the "experimental group" sprouted, except one, while only one mung bean in the "control group" sprouted. This makes me wonder why the mung beans in the "control group" grow slowly. The science teacher's answer is: "Because sunlight is essential for mung bean germination, if there is no sunlight, mung beans will grow very slowly." And with sunshine, mung beans will grow faster. I also have a little secret: spread a layer of wet tissue on the ungerminated mung beans, and the mung beans will grow quickly.

Today is the third day of planting mung beans, all mung beans have sprouted, and two mung beans in the "experimental group" have begun to grow stems, which look very cute. But the "control group"
Mung beans grow very slowly, and they haven't all sprouted yet! But the germinated mung bean also grows well, but it is very thin. These findings surprised me, because my mung beans grew so well that even the mung beans in the "control group" sprouted, which was so cute.
