Today, when I came home from school, I asked my grandmother for 30 mung beans according to what Teacher Yang said, and carefully put them in a mineral water bottle filled with water. As I put it on, I thought: Little mung beans will sprout soon, so I can write an observation diary quickly! After putting it away, I went to do my homework. After finishing my homework, I said to the little mung bean, "grow quickly, grow a little seedling!" " Grandma saw it from the side and couldn't help laughing and said, "Wei Wu, don't be so impatient! This can't be changed in a minute. Come and see tomorrow! " I thought about it and found it quite reasonable. I went to bed after dinner.

Today, I got up early and went to see my green color excitedly. It still didn't germinate. I was depressed and asked my grandmother, "Grandma, didn't you say that mung beans will change today?" Why not? " Grandma said, "How can there be no change? Take a closer look. " I looked at it carefully and found that mung beans were a little bigger than yesterday, so I asked, "Grandma, how did mung beans get bigger?" "It's not getting bigger, it's swollen." "Why do mung beans swell?" I asked, "Is it because of drinking water?" "Yes, it needs to swell before germination." "oh! That is to say, it will sprout after a while?

I was so happy that I immediately called my grandma and said, "Look, grandma! Mung beans are sprouting! " Grandma said, "Why send one? Don't worry, call me when you send the third one. " So I waited and waited until my mother called me, "Wei Wu, go to bed!" " I went to sleep reluctantly, and I thought, "There will be some mung beans sprouting tomorrow!" "

The sound of "Ding Ding Ding" alarm clock reached my ears, and I suddenly remembered my mung bean. I turned over, sat up, jumped out of bed and put on slippers, and walked to the front of the coffee table in three steps.

It's a little wet, as if it had just emerged from the water. It's just that they only show a little head, and most of them are still hidden in the soil. I wonder what these "little heads" will look like?
