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 ... Now there is a soybean seedling wrapped around the safety window to help it 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.
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. If there is no water, he will die and he 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!
The fourth grade soybean observation diary 3 came home from school today, and I'm going to observe soaking beans.
At five o'clock, I took out some beans from the kitchen, put them in a bowl, scooped up a spoonful of water and soaked them. After 40 minutes, I came out and saw that the surface of the beans was like the wrinkled face of an old woman. Then, I carefully observed the soybeans and found that some soybeans were bubbling. I think it's because beans absorb water. After about 20 minutes, the skin of the beans looks a little cracked. Why? It turns out that the skin of beans should absorb water and expand, and then let the beans absorb water. The next morning, all the beans swelled up, almost twice as big as before, which is probably the green beans before the beans dried up.
At noon the next day, I looked at the soybeans again. The beans had grown to the size of peanuts. I gently took off his coat. I was shocked. Soybeans not only swell, but also germinate in water. I am so happy to see the yellow-green buds on soybeans.
On the third day, I couldn't wait to see soybeans. The water soaked in soybeans became turbid, so I shook the bowl and the water stuck to the wall of the bowl. Suddenly, I smelled a faint smell. At first I thought it was the smell of beans. Later, the smell became heavier and heavier. Only then did I know that it was the smell of beans, so I changed the water immediately.
Fourth grade soybean observation diary 4 On my mother's balcony, I planted a golden soybean.
A few days later, as soon as I got up, I was worried about Xiaozhou and wanted to know how it was today. Is it sprouting? With doubts in my heart, I ran to the balcony, opened the lux curtains and rushed to my mini flowerpot. I saw the small soybeans sprouting and yellow. Although the bud is still very small, I feel as if it is smiling at me and saying happily, "Ah! I finally got out, but I'm exhausted! " But it's weird. What's down here? I'm so tired, I want to have a rest and have a look.
After a few days, the main branch of adzuki bean grew out, and there were many branches on the main branch, and the number of branches was countless. The branches are grayish brown and very hard. You can't pull out a dead branch unless you pull it hard. Many emerald leaves have grown on the branches. They are moved by the breeze and sway like elephants' noses, making people feel comfortable and beautiful.
After about two weeks, I was pleasantly surprised to find that the leaflets of emerald became bigger, and the color changed from light green to dark green, and even a small flower appeared! The flower of soybean is white, flying into the sky like angels in white. Tofu pudding is very small, like small sesame seeds, in strings. At first glance, it looks like a bunch of lilacs smiling at me. When the wind blows, they sometimes swing around like Donald Duck, and sometimes they dance beautifully.
