Ten diaries

Today, the teacher gave us an assignment-observing beans and then keeping 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 some beans, but what do you do with them?" What kind of beans do you want? "I said," this is one of the homework. Take mung beans! "My mother-in-law gave me mung beans. I quickly took a paper cup, then stuck a hole in it with a toothpick, and then stuffed a sponge under it.

Finally, add mung beans and a little water, and put the paper cup on the table. I stared at the mung bean seeds. One minute, two minutes, three minutes, the beans didn't change at all, so I got angry and said, "Damn beans, why don't they sprout!" " Just then, my mother came in and said to me, "Silly boy, how did the beans sprout so quickly?" It takes at least 36 hours to germinate! "

The next day, after school, I couldn't wait to run to the paper cup and look at it carefully. Oh! The beans sprouted in vain. I think: beans have only grown a little these two days. How many days does it take to grow up?

On the third morning, I got up and went to the beans to check their growth. So for two consecutive days, the growth of beans did not change much, but the buds grew taller.

On the afternoon of the fifth day, bean sprouts finally had a completely different change-two bright green leaves unfolded, and I jumped up happily and cried, "My beans have leaves!" " "

By observing the growth process of mung bean seeds, I understand that the growth of plants can not be completed overnight.
