Ten entries in the diary

Today, the teacher assigned us an assignment - observe the beans and write a diary.

When I got home, I immediately asked my mother-in-law: "Mother-in-law, are there any beans at home?" My mother-in-law said: "There are beans, but what are you doing with the beans? Which kind of beans are you getting?" Said: "This is one of the homework, let's get mung beans!" My mother-in-law gave me mung beans, I quickly took a paper cup, then used a toothpick to pierce a hole under the paper cup, and then put a sponge under the paper cup.

Finally, add the mung beans and a small amount of water, and put the paper cup on the table. I stared at the mung beans aimlessly. For one minute, two minutes, and three minutes, the beans didn't change at all. Then I got angry and said, "Damn beans, why haven't you sprouted yet?" At this moment, my mother left. He came in and said to me: "Silly boy, how can the beans germinate so quickly? It will take 36 hours at the fastest!"

When I came after school the next day, I was impatient. I ran to the paper cup and took a closer look into the cup, ha! The beans all sprouted white buds. I thought: It took two days for the beans to grow a little. How long will it take for them to grow?

When I got up on the morning of the third day, I came to the beans again to observe the growth of the beans. This continued for two days. There was no big change in the growth of the beans, except that the shoots grew taller.

On the afternoon of the fifth day, the bean sprouts finally had a very different change - two tender green leaves unfolded. I jumped and shouted happily, "My beans have grown leaves!"< /p>

By observing the growth process of mung beans, I understand that the growth of plants cannot be completed overnight.
