Daily observation diary

Daily observation diary 1 This is an interesting observation class, which is to observe watermelons. I have seen a bunch of watermelons, large and small, lying on the ground and hidden in bags. It seems that there are many interesting things to see!

As I expected, the teacher not only let us observe, but also let us taste. The teacher picked the biggest watermelon, so we quickly went forward and touched it with our hands. Hey! Smooth, slippery and cool. I patted the watermelon hard, and the watermelon made a dull sound, indicating that the watermelon was ripe. Touching the watermelon, I thought to myself: the farmer's uncle is so hard and so great. It is not easy to turn small watermelon seeds into big watermelons.

Look, watermelon has a thin tail. There is a small spot on the top of watermelon, like the small eyes of watermelon. Watermelon is dressed in dark green, like a soldier and a fat doll. The teacher told us that if there is a depression in the watermelon, it means that the watermelon pulp is empty, and people call it a "hollow melon".

At this time, the teacher held the melon in his left hand and the knife in his right hand, only to hear a "crack", and the watermelon was split in half. Gee, the inner layer of watermelon peel is not dark green, but a white and green color. The red flesh is like the rising sun. White shapeless watermelon seeds are like diamonds. Why are seeds not shapeless? Because it is seedless watermelon. The teacher cut the watermelon into pieces. I couldn't wait to pick up a piece and bite it. Rustling, so sweet! How delicious! I don't know why the ancient poem "pity for farmers" came to my mind: "mow the grass at noon and sweat drops." Who knows that the Chinese food on the plate is hard. "

This is really an interesting observation class. I not only tasted the delicious watermelon, but also learned a lot of knowledge and observation. This is killing two birds with one stone.

Daily observation diary 2 One day, I had a whim to soak a peanut or soybean and observe their germination process. So I asked my mother for some peanuts and soybeans, soaked them in a bowl with half a bowl of water, and began my long-term observation. I set the observation time as one week.

Monday: Watch while eating breakfast. At first glance, I found that peanuts were stuck on the wall of the bowl and the color of the water turned red. The originally smooth peanut coat became wrinkled. Soybeans have not changed either. Or sink to the bottom of the bowl.

Tuesday: In the morning, I went to observe it again. In the light, I found that there seemed to be a bug on the peanut head, one by one, one by one. I was shocked and called my father and grandfather. "Look-it's moving." Dad and grandpa saw it and said with a smile, "That's a bud eye, it's going to sprout." I'm so happy! Jump, jump. "Dad said," You want it to sprout, right? " "Yes," I replied. Dad added: "you can't always soak in water." If you want to plant it in the soil, you can't always soak it. Have you forgotten the conditions for seed germination? "I see. I did as my father said.

Thursday: Oh, my God! I got up early in the morning and took a look. I was really shocked. Only one day later, peanuts and soybeans germinated. Without waiting for a week, Xiaoya has grown up and I have gained a lot. composition

Daily observation diary 3 20 17 12 3 Monday was sunny and happy.

This morning, it was foggy, and I came to school at a brisk pace.

The campus in the morning is a world of reading aloud. I quickly walked to the third floor, flew into the classroom, put down my schoolbag, took out my textbook, and read Hong Kong, the Bright Pearl with emotion.

In Chinese class, Mr. Zhong made the class very vivid. While giving a lecture, Mr. Zhong danced with the expression of arguing between pottery pots and tin pots. You see, the tin can is so domineering, and the pottery can is so wronged. I saw her angry for a while, her eyes widened for a while, and her hands crossed and she shouted, "How dare you compare with me!" " "After a while, his eyebrows fell down again, his eyes squeezed into triangular eyes, and he pursed his mouth with a helpless expression:" Why do you say that? "Let's live in harmony. What is there to argue about? " Teacher Zhong's vivid performance made the students laugh.

On the physical education class, xu teacher led us to play a game-drilling hula hoops. Students practice according to xu teacher's method. With xu teacher's order, four groups of students started a diamond ring competition. We lowered our heads, drilled through the circle, jumped with our legs and jumped out of the circle. I saw people in other groups sweating through every circle, their eyebrows raised and their mouths closed, for fear of saying something wrong. After many cycles, our group is far ahead. Other groups are not far behind. At this moment, the last person in my group shouted, "Done!" Xu teacher announced loudly: "The third group won the first place!" "Yes!" The whole group jumped three feet high with excitement, and the joyful songs resounded through the sky. ...

In math class, a "strange question" given by teacher Lin aroused our thinking. Use a series of "strange" questions to lead us into the ocean of thinking and reap the fruits of thinkers.

In English class, the teacher taught us to spell every word carefully, let us play in the jumping letters and words, let them become our prisoners one by one, and let us learn in entertainment.

This is my day's study life. Do you like it, children?

Daily observation diary 4 This afternoon, I observed small ants on the grass.

I found a big stone. When I lifted it, I saw a small hole under it. I thought, "There must be ants in the hole." So I shook it with a twig. After waiting for a while, a small ant finally came out, and then a group of small ants came out, which dazzled me. In this dense pile of ants, I found two ants fighting. I thought: it is a small animal, how can it fight with each other? I separated them with twigs.

At this moment, I found a smaller ant looking for something. I saw a bug, so I picked it up with a twig and put it in front of the little ant. But it didn't eat anything and ran back to the hole without even looking. I thought: Why don't little ants eat? After a while, a large group of ants rushed out of the hole. At this time, I finally understood that the little ant went to tell the news. They began to carry bugs together in Qixin. When I carried the worm into the hole, I found that I couldn't get into it. I saw the ants use their own tools to move down from the head of the bug bit by bit. The little ants all seem to be hardworking and hardworking. After a long time, it was getting late. Although the handling work continues, I must go home. I always see ants carrying food in front of my eyes. I thought: Can they take away all the bugs?

After school at noon the next day, I went to see it again and found that only the skin of the worm was left in front of the cave, and there were a few ants in twos and threes. It is really "hard work pays off." The unity, cooperation and perseverance of ants will benefit me a lot.

Daily observation diary1October 3, I was idle and suddenly remembered the special "homework" of raw bean sprouts assigned by the teacher. I prepare some high-quality mung beans. Remember to be good, otherwise there will be no high income. First, I wash them with clean water to get rid of sundries. Then I soaked them for 12 hours and fished them out. I carefully prepared a warm home for these little creatures, put them in the steaming compartment of the rice cooker and spread them with carefully prepared wet cloth.

1It was sunny on October 4th.

You did a good job. I woke up the next morning and sprouted. How cute the mung bean sprouts are. The little guys showed their yellow faces. It seems that he said to me, "don't underestimate me, in fact, I am very cute." I kind of like these little things. Mother said, "Water it often." I specially used a mineral water bottle, punched several small holes in the bottle cap and watered it with dew as sweet as flowers. Those little things are greedy. Some of them are lying and some are standing, and they all have a little white foot like a silver needle, and they are crowded together like sleepy pigs.

1It was sunny on October 5th.

"The bean sprouts have grown leaves." My mother's crying woke me up from my morning dream. It's time for me to get up and enjoy the "bean sprouts" of labor. See, take out a small yellow leaf, covered with a layer of transparent clothes. Some small leaves completely burst the little clothes outside, and the leaves outside stretched out around. I smelled a faint fragrance and quickly poured water on them. Those little creatures are like small mouths trying to absorb nutrients. I see their feet are really small and delicate. Watching them grow up happily, my heart is full of joy.

Although I haven't traveled far these days, eating raw bean sprouts has benefited me a lot. I witnessed the whole process of plant growth. During the long vacation in October, I felt very full and happy.

Daily observation diary will be fine on Tuesday, September 6th16th.

Today, Teacher Sun left us an assignment to go home and soak mung beans. When I got home, I couldn't wait to take out a small bowl, filled with some mung beans and water. After a few minutes, mung beans did not change. After an hour or so, hey! I found mung beans wrinkled, like an old woman's face.

It will be fine on Wednesday, September 17.

In the morning, I got up from bed and went to see my little mung bean. Wow! My little mung bean skin cracked and bulged at the same time. My mother said, "That's the cotyledon of mung bean." After school in the evening, I hurried to see my baby mung bean. The "green coat" of some small mung beans has been taken off, leaving only a white pearl-like thing, and the teeth have grown. The water became turbid and fishy. I quickly changed some water for the little mung bean.

It rains on Thursday in September 18.

On the third night, the first thing I did when I went home was to see my baby mung bean. Wow! I can't help but be surprised that the little mung bean has grown so big. I put the mung bean on the table with a cotton swab and observed it carefully. I found that the buds of mung beans are longer than yesterday, just like tadpoles. These buds are several centimeters long! The seedlings are white, crisp and easily broken. The original seedlings had no leaves and were bare, just like stems, which were bare.

Through this observation of mung beans, I learned that as long as you observe one thing carefully, you will learn a lot from it. I also learned to be patient in everything.

Daily observation diary 7 "It is green when you see it, red when you eat it, and black when you spit it out" (name a fruit). Everyone may know that the answer to this riddle is "watermelon". But what I'm talking about today is not watermelon, but watermelon vine.

Watermelon vines are not very long, but they are lush.

One day, the watermelon vine was tender and delicate in the hot sun. Why is this? I wonder if the temperature is too high. A few days ago, I found the answer on the Internet: Watermelon belongs to the live broadcast stage: when the cotyledons are unearthed, they need sufficient sunshine and the temperature should be adapted to 20 -25 degrees. Oh! It turns out that the temperature is really too high. At that time, the temperature was over 30 degrees, which made watermelon delicate. Therefore, my idea has been confirmed.

Do you know the origin of watermelon? I don't know! Then let me introduce you:

China is the largest watermelon producing area in the world, but watermelon is not native to China. Watermelon originated in Africa. It was originally a wild plant of Cucurbitaceae, which was cultivated artificially to become an edible watermelon.

As early as 4000 years ago, Egyptians planted watermelons, and then gradually moved northward, first from the Mediterranean coast to northern Europe, and then south to the Middle East, India and other places. In the 4th and 5th centuries, watermelon was introduced into China from the Western Regions, so it was called "watermelon".

According to Xu Guangqi, a scientist in the Ming Dynasty, the book "The Complete Book of Agricultural Administration" records: "Watermelon is named after being planted in the western regions." Li Ming's Compendium of Materia Medica records: "According to Hu Jiao of Uighur, there is a kind of melon called watermelon. Watermelon entered China from the Five Dynasties; There are north and south today. " Thus, watermelon cultivation in China has a long history.

Daily observation diary 8 201711014 Wednesday sunny.

The Quaker's name for Sunday

In order to cultivate our observation ability and writing ability, the teacher assigned a special homework today-planting garlic seedlings.

After school, as soon as I got home, I took two fresh garlic and sat by the coffee table to peel them. It is not easy to peel fresh garlic. Gently rub it with your hand, and the outer skin will be easily peeled off. But the innermost skin is tightly attached to the garlic cloves, which is really difficult to peel. So, I rubbed it hard with my thumb and rubbed it a few times before erasing it. It took me more than ten minutes to peel both garlic. Then, I put them in a small plate. That garlic is like a beautiful Bai Lianhua. With a little clean tap water, the lotus is lifelike.

2017 165438+1October16 It will be fine on Friday.

the third day

Today, I found that some garlic sprouted a little, some grew about a millimeter, and some grew a centimeter! There are some white roots at the bottom of garlic, like grandpa's white beard.

2017165438+1October1Thursday is fine.

Seventh day

Garlic seedlings grow so fast! Some have grown more than a centimeter. However, as individual garlic became "thin", Bai Lianhua began to shrink slowly. The longer the fibrous roots at the bottom of garlic are connected together, the garlic in the middle can't even be pulled up by eight buckets. Garlic seedlings were light green at first, but as they grew up day by day, turquoise buds appeared on the stems, which looked like a small onion. No wonder the garlic sprout grows so fast that it drinks all the water in the small plate.

I think: if I were a garlic seedling, I would grow more than a centimeter a day like it.
