Chapter 1: When I came home from school, I immediately emptied the water in the cup, because my classmate Hou Yiqing said to me, "There can't be no water in the soybean cup. Without water, he will die and will not sprout! "
After I poured water, I found a crack in the soybean. I asked my father why. Dad said, "There is a crack in the soybean, which means the soybean is going to sprout." I jumped for joy. A closer look reveals that soybeans are much flatter. I asked dad again why? Dad thought for a moment and said, "to tell the truth, I don't know!" Let's check online together! " We searched for a long time, but we didn't find a satisfactory answer! I wonder who can tell me why soybeans are round before soaking and flat after soaking?
Although we didn't find the answer on the internet, we were surprised to find that the internet said: Don't soak beans in too much water, or they will drown! Hou Yiqing is wrong.
According to the internet, I quickly poured some water into the cup and put it in a sunny place, hoping that they would grow up quickly under the sunshine.
My heart is full of expectations, and I will see "Sister Bean Sprouts" soon!
Chapter two: diary of soybean observation in grade four. Once I began to do the experiment of "soybean growth process".
I'll prepare transparent plastic cups, dirt, paper towels and soybean seeds first. Then spread paper towels around the cup and put more than half of the soil in the cup. Then, I put some seeds between the cup and the tissue. Finally, I crushed a small part of the remaining mud and put it in a cup (the seeds are about one centimeter deep from the surface), and poured some water to make the paper towel completely wet. So the seeds were planted.
A few days later. I came to the windowsill to observe the seeds. I found the color of the seeds changed a little. Originally, the color of the seed was big yellow, but after these days, the appearance of the seed was a little light and it felt a little transparent. The seeds are particularly full and the seed coat is a little cracked.
Two days have passed. I went to the windowsill again to observe the seeds. I looked into the cup. To my surprise, the seeds germinated. The shell of the seed cracked. Buds are drilled from the inside, and the color of buds is light yellow with a little cyan. The top of the bud is pointed and looks very tender. This is the bud head. The bud head grows downward. There is a question in my mind: why does the bud of a seed grow down? Isn't this impossible to drill out? I thought about it and watered it.
The next day, I came to the window platform again to observe the seeds. Through my observation. Seeds change greatly now and when they germinate. When it germinated, the seed shell just broke, and now most of it has fallen off. I really want to help it peel off all the shells. The real small leaf bud in the seed has left its original position and is close to the outside. Two trees emerged from the soil. Originally it was closed, but now it is scattered, with a small bud in the middle. I also found that each bud has two leaves, which look furry like a love shape.
A few days later, I came to the windowsill again. There were many small green bean sprouts in the cup. I also found that its leaves are two opposite pieces.
Now we know why the new bud of this seed grows downward. That's because it's not a bud, but a root, so it should grow down.
When I came to the windowsill again to observe, the soybean had changed from a seed to a bean sprout, and then it grew up slowly from the bean sprout. . . . . . Now there is a soybean seedling wrapped around security window to help him grow. This soybean seedling is also the fastest growing one.
Although growing soybeans is small, it is a good start for me to experience plant growth.
Chapter III: Observation Diary of Grade Four Soybean I used a plastic bottle, filled with some soil, planted several mung beans, watered them, and began to wait for mung beans to germinate.
A few days later, both Hushi Duomo and Mung Bean successfully produced green seedlings. I looked at them and felt that they were fighting with sharp broadswords like knights, trying to figure out who was the first to emerge and who could see the wonderful world outside.
A few days later, I found that my bean sprouts have grown tall and grown up. I measured it with a ruler, but I didn't expect it to grow two centimeters faster and one millimeter slower. I am so happy that I hope the mung beans I grow will grow faster and faster.
About three or four days later, when I went to see my bean sprouts again, I found that they were a little longer. Although I am happy, I am still a little disappointed, perhaps because I can't measure how long their roots are. Because if you have the length of roots, you can know what their total length is, which slightly narrows my doubts about these mung bean seedlings.
After a period of time, these bean sprouts grew some round little things inexplicably. I looked around and didn't know what it was, so I asked my mother. I didn't know it was their fruit until I asked! But I want to take them off again. I like this little thing very much, but I still hold back. See what else will grow.
Through this incident, I understand that everything should be patient, but not anxious.
