(Author's note: A book friend pointed out the common sense mistake, so it has been corrected.)
In the natural science class, the teacher did not ask for much homework, and it was a bit like an open-ended question. The children could freely choose the plants they wanted to plant, and they could also invite their parents to participate, but they had to clearly write in the experiment report what they had done personally. Of course, the most important thing was that the observation experiment report had to be submitted once a week, so that the teacher could see their progress and perseverance!
"What do you want to plant?" Yang Yi asked with a smile.
Xi Xi was still very interested in this. When she got home, she did not even bother to change her clothes. Wearing her school uniform, she ran around excitedly with the natural science textbook.
"I want to plant a peach tree. PaPa, our school has very beautiful peach blossoms. Teacher Cen has taken us to see them." The Teacher Cen that Xi Xi was talking about was her natural science teacher.
The little girl excitedly went to the floor-to-ceiling window in the living room, pointed to their yard, and said, "If we plant a peach tree at home, it will be very beautiful!"
Yang Yi did not know whether to laugh or cry, and said, "Peach tree? Peach tree can't do that. If you plant a peach tree, it may take several years to see results. Then you won't be able to submit the observation homework to the teacher. "
Hearing this, Xi Xi retracted her small hand and said with a little distress, "Is that so? Then, PaPa, what should we plant? "
Yang Yi carefully read the description in Xixi's natural science textbook and said with a smile, "You're talking about growing vegetables here. The effect of growing vegetables is very fast, and it changes almost every day. If it doesn't work out, there will be new changes every week. So, you can choose some vegetables that you like to plant. "
Xi Xi raised her small head and looked at her father attentively. After he finished speaking, she blinked and said, "Then let's plant Apple! I also like Apple very much! "
"Apple is not a vegetable, it's a fruit!" Murphy, who was listening to the side, could not help but laugh. "I know this. How can you confuse it?"
"But, but Apple is also a vegetable! PaPa sometimes makes a dish! "Xi Xi felt that her mother's words were not authoritative enough, so she pouted and argued.
"Mom is right. Apple is a fruit, not a vegetable. Even if Dad made it into a dish, wouldn't that dish be called a fruit salad? It's not called vegetable salad, right? "Yang Yi smiled and patted Xi Xi's shoulder.
The little girl thought about it and reluctantly accepted her father's explanation.
Yang Yi also reflected on himself. Just now, he had allowed Xi Xi to choose. Was it too difficult for this young girl who didn't know much?
Therefore, he thought about it and decided to narrow down the selection range for Xi Xi.
"Now, Dad will give you a few choices. There are cabbages and celery. Their characteristics are that they can be directly cultivated with the part of the root. However, they can be cultivated with celery or cauliflower, or with the leaves of carrots or carrots. These two kinds are different from the previous ones. They need the head of the carrots, which we usually don't eat. Of course, they are not carrots, but carrots and tassels, which are good for ornamental purposes like cauliflower." Yang Yi smiled and said to Xi Xi, "There are also green beans, which can grow green bean sprouts, the kind that you like to eat very much. Potatoes can also be planted. Unlike the previous ones, they can be directly cultivated with the cut tubers."
Yang Yi still had relatively rich agricultural knowledge from the memories of his predecessor's farming in the countryside. At least, it was enough to deal with Xi Xi's homework this time!
As Yang Yi spoke with assurance, Xi Xi and Murphy, who were next to him, listened with admiration.
Murphy sighed with emotion and said, "How do you know so much?"
"Papa, I want to plant all of them." Xixi was very excited when she heard this. She took her father's hand and jumped up on her own. Her little face was very excited as she asked, "Papa, our house is so big. Let's plant them all, okay?"
Murphy also said with interest, "Since you've planted them, let's plant more! I want to see it too! "
Yang Yi looked at Xi Xi's small head and eagerly looked up. He smiled and said, "Okay, in that case, we'll plant one of each type. Since we have ingredients at home today, celery and cabbage, we'll plant celery. Celery is edible. The taste of cauliflower is average. As for radishes and carrots, we happen to have carrots at home, so we'll plant carrots, okay?"
Xi Xi's little face suddenly became a little conflicted. She slightly pouted her little mouth, twisted her body, and muttered unhappily, "But, Papa, I don't like celery."
In the past few days, her father had let her eat celery several times. Although Xi Xi tried her best to eat it in order to make her teeth look better in the future, she still didn't like the taste of celery very much!
"Okay then! We'll plant cabbage. The cabbage will indeed look better. " Seeing this, Yang Yi couldn't help laughing and said, "There are no roots of cabbage at home today. Papa will get you one tomorrow."
"Yes, yes, I want to plant cabbage, cabbage!" The little girl happily opened her arms.
…
Since the decision had been made, after dinner tonight, Xi Xi couldn't wait to follow her father and start the preparation work of planting vegetables.
"Come on, these are mung beans. Soak them in water first. Do it like you used to wash the rice when you helped Papa cook, but you have to clean up the mung beans floating on the water." Yang Yi took a glass bowl that was usually used to store fruit salad, poured three handfuls of mung beans into it, and then handed it to Xi Xi.
"Okay!" Xi Xi ran over attentively, took the bowl, ran to the sink, turned on the tap, and filled it with water.
Yang Yi stood behind the little girl, watching her put her little hand in and pull it a few times.
"Okay, pick out the mung beans floating on the water. Remember these steps you did today!" Yang Yi said with a smile, "Our experiment has already started. You have to record these in your experiment report!"
Xi Xi's little face tensed up, and her little mouth that was laughing just now also pursed. It was obvious that she was serious.
The little girl carefully scooped out the green beans floating on the surface of the water with her two little hands as if she was scooping water.
"Do you know why you have to fish out these floating mung beans?" Yang Yi asked with a smile.
Xi Xi shook her little head in confusion.
"Observe the difference between the mung beans floating on the water and the mung beans still under the water." Yang Yi didn't give the answer directly.
Xi Xi stopped what she was doing. Following her father's instructions, she picked up two different mung beans and observed them closely.
"Be gentle with this one. It seems to be hollow!" Xi Xi looked back at her father with some surprise.
"Yes, because these are the shells of the mung beans. Before they were sold to us, they might have been damaged during the production process, so they fell off the shell. The reason why we have to pick them out is that this kind of mung bean shell has no substance, so you can't grow mung bean sprouts! "Yang Yi patiently explained to the little girl at this time.
