humanity under observation

Turtle Observation Diary [Date] [Day] [Weather] Today, I began my observation of turtles. The turtle's small body seemed to contain a great mystery. Its shell was like a sturdy little house with regular patterns on it. These patterns were like traces left behind by time, but also like a unique mark given to it by nature. Its head would always stick out carefully, and its bean-like eyes would roll around, curiously looking at the world around it. When I put it in a small basin, it began to crawl slowly. Its short but powerful limbs moved rhythmically. Although it was not fast, every step was very stable. Its crawling trajectory was curved and did not seem to have any specific direction. It was more like it was exploring a new environment. Sometimes, it would suddenly stop, as if it was thinking about something important. After a while, it would continue moving forward. I fed it some turtle food, but it didn't notice the food in front of it at first. After a while, perhaps it smelled the fragrance of the food, it slowly crawled toward the turtle food, then opened its small mouth and ate it bite by bite. The way it ate was very cute. In the process of observing, I also found that the turtle liked to bask in the sun. When I put it in a place with sunlight, it would stretch its neck and expose its body to the sun as much as possible, looking very comfortable. After a day of observation, I realized that although turtles moved slowly, they had their own unique rhythm and habits. They were really interesting little animals.

[Observing Kitten] Kittens were extremely cute and intelligent animals. Its appearance was very charming. Its eyes were like crystal clear gems, shining with a mysterious light in the dark. That was because the cat's eyes were special. Even in the dark night, it could see clearly. Their ears were sharp like two small mountains. They were always alert. As long as there was any movement in the surroundings, their ears would move flexibly and accurately capture the source of the sound. The kitten had soft and thick pads on its paws, which made it walk quietly, like a silent little ghost. Its whiskers were thick, but don't underestimate them. This was the kitten's extremely sensitive " measuring tool ", which could accurately measure the size of various holes. Kittens had interesting habits. It was a gluttonous little guy. As long as it smelled the fragrance of fish, it would run over with light little steps. Its eyes were fixed on the food, and its throat emitted an eager "meow" sound. It was also very playful. It could play with a small ball of yarn happily. It would pounce on the ball of yarn for a while and chase its tail in circles for a while, as if it was the most fun game in the world. Kitten was particularly fond of sleeping. It slept soundly most of the day. On the sofa, on the windowsill, and in the cardboard box, there were its comfortable little beds. However, although it was usually lazy, once it found traces of a mouse, it would immediately be energetic and patiently guard the mouse hole for a long time. When the mouse appeared, it would pounce at lightning speed and press the mouse tightly under its claws. This was a kitten, a cute and unique little animal.

The following is an example of an observation diary essay about observing kittens: [Kitten Observation Diary] [Date] [Day] [Weather] Today, I found a kitten in the corner of my neighborhood. Its fur was mainly white, with a few black spots mixed in. It looked like ink had been accidentally dripped on a white rice paper. It looked interesting. The kitten's eyes were big and round, like two crystal clear gems, shining with a mysterious light in the darkness. Its ears were sharp and always erect, like two sensitive small radars. Any subtle movement could not escape its ears. Its nose was pink and tender, small, but very sensitive. Every time I brought food close, it would always be the first to smell it. The kitten's behavior was very interesting. When it walked, its footsteps were light, like an elegant dancer pacing. When it found a butterfly, it instantly changed its appearance. Its eyes were fixed on the butterfly, its body was lowered, and it quietly approached. Its tail was gently swaying left and right, ready to pounce at any time. Unfortunately, the butterfly flew away, and the kitten could only shake its tail helplessly. The kitten was even cuter when they were eating. I gave it some cat food. It first carefully approached and sniffed with its nose before starting to eat. It ate slowly, but elegantly. It chewed carefully with every bite and licked its claws and mouth after eating, cleaning itself up. Kittens were also very unique when they rested. It would find a quiet corner and curl up into a ball, like a furry ball. Its ears would occasionally twitch, as if it was alert to the movements around it. This kitten is really full of life and vitality. It has brought me a lot of joy and surprises. I hope to see it every day in the future. maybe [Kitten Observation Diary] [Date] [Day] [Weather] A new kitten has come to my house, which has added a lot of fun to my life and also started my journey of observation. When the kitten first arrived at my house, it was full of curiosity and vigilance towards its surroundings. Its soft fur felt as smooth as silk. Its fur was gray and black, as if it was carefully mixed. The kitten's eyes were deep blue, like a peaceful lake. During the day, its pupils would narrow into a thin line, but at night, its pupils would enlarge, as if to capture more light to find prey. Its whiskers were long and tough, neatly arranged on both sides of its mouth. This was an important tool for it to sense its surroundings. The kitten was very lively when it played. Its favorite toy was a little ball of fur. It would use its claws to gently poke the ball of fur, then chase it around. From time to time, it would use its mouth to hold the ball of fur and swing it around. Sometimes, it would play with itself, running around the room, jumping on the sofa and hiding under the table. Kittens slept longer. It could always find a comfortable place to nap. Sometimes it slept comfortably on the windowsill with the sun shining on it. Sometimes it curled up in the nest I prepared for it with its ears close to its head. As time passed, the kitten gradually became familiar with this home, and a special emotional bond was established between us. Every time I came home, it would always run to the door to welcome me, rub around my feet, and make a soft "meow" sound, as if telling me that it missed me very much. This kitten has become an indispensable part of my life. I look forward to continuing to observe its growth.

#Kitten Observation Diary September 8th, Sunday, sunny to cloudy Today, I found out that the stray tabby cat in the neighborhood had given birth to a litter of kittens next to a pile of abandoned furniture. The kittens were like little mice as they curled up beside the big tabby cat. Just as I was about to approach and count the kittens, the big tabby cat suddenly stood up and stared at me fiercely. I was so scared that I quickly turned my head and ran away. September 9th, Monday, sunny In order to resolve the hostility of the big tabby cat towards me, I asked my mother to prepare a small bowl of food for me before going downstairs to explore the cat nest. When he arrived at the cat nest, he found that there was leftover food in the cat bowl. The big tabby cat had already eaten breakfast and was lying lazily in the nest. The kittens were all lying under it. Perhaps it saw the cat food in my hand, but its hostility towards me was no longer so deep. It narrowed its eyes and looked at me without moving. September 11th, Wednesday, sunny Today, he could finally observe the kitten up close. The kitten's skin was a little red, and it had thin white fur. Its eyes were closed, and its limbs would move occasionally. I counted a total of five of them. They were all curled up and leaning together as if they were still asleep. Their stomachs rose and fell with their breathing, and their noses opened and closed. It was very interesting. September 17th, Tuesday, sunny Today is the Mid-Autumn Festival, so I decided to give the big tabby cat some delicious food. When I ran to the cat nest, the tabby cat meowed at me and then lowered its head to eat with relish. Looking into the cat nest, the kitten had changed greatly. They were staggering about in their nests, and two of them bumped into each other after a few steps, fell, and staggered to their feet. Perhaps they wanted to come out and admire the moon.

The following is a diary of observing cats: ** 1. Observe the cat's appearance ** 1. ** Overall characteristics ** - It described the size of the cat, whether it was small or large. For example,"This cat is small and looks very delicate." - When it came to the color and texture of a cat's fur, it was like,"It's covered with snow-white fur. The fur is soft and smooth, like high-quality silk." 2. ** Local features ** - Eyes were one of the characteristics of cats. One could write the color, shape, and characteristics of the eyes. Its eyes were big and round, like two crystal clear emeralds, and its eyes were full of intelligence. - Her ears were also very unique."Those triangular ears are always erect, as if they are constantly alert to the movements around them." - "The long whiskers at the corner of the mouth are slightly upturned, like a cat's special sensor." ** 2. Observe the cat's behavior ** 1. ** Eating habits ** - She recorded the cat's appearance when it ate."It's very gentle when it eats. First, it sniffs the food with its nose, then its little tongue licks the cat food bit by bit. Every few bites, it will stop and look around." Or,"The cat wolfed down its food. It pounced on the food it saw and chewed it up." 2. ** Activity Habits ** - The daily activities of a cat were very rich. One could describe its walking posture."It walks with light footsteps, like an elegant dancer, quietly shuttling through the room." - The cat's resting state could also be written as: "In the afternoon, the cat is lying lazily in the corner of the balcony, curled up into a ball, with its eyes half-closed, and occasionally taking a nap." - If you observed the cat playing, you had to describe it in detail."It saw a small ball of paper and instantly became interested. It kept fiddling with the ball of paper with its claws. For a while, it threw the ball of paper here and then chased it there. It was having a lot of fun." 3. ** Special Habit ** - For example, cats 'cleaning habits."Cats love cleanliness. Every day, they will comb their hair with their tongue, starting from the head and licking all over their bodies, even their claws." Or like some cats who had the habit of burying their feces,"Every time it goes to the toilet, it will use its claws to dig in the cat litter until it completely buries the feces." ** 3. Observe the cat's social behavior (if there is a chance to observe)** 1. ** Interactions with the same kind ** - For example, when two cats meet, they first sniff each other's noses and then start licking each other's fur. They look very intimate. Or,"When a strange cat intrudes into its territory, it will bow its back, raise its fur, and let out a low roar to warn the other party not to approach." 2. ** Interactions with Humans ** - A cat's attitude towards its owner could be written like this: "Whenever the owner comes home, the cat will run to the door to welcome him. It will rub its head against the owner's leg and meow, as if it is expressing its longing." Or,"This cat is timid and will hide when it sees strangers. It will only carefully stick its head out when its owner calls it." ** 4. Observe the changes in the cat over time (if it is long-term observation)** 1. ** Body growth ** - If it was a kitten, he could write about its growth process."When it first came, the kitten was still very small and walked unsteadily. After a few months, it has grown much stronger and more agile." 2. ** Change in behavior ** - For example,"Kitten was very naughty when she was young and always caused trouble at home. As it grows older, it becomes more and more docile. Most of the time, it lies quietly on the side." When writing an observation diary, you should record the various conditions of the cats you observed in a temporal order. You can also add your own feelings and thoughts to the diary to make the diary more lively and interesting.

The following is an observation essay about kittens: Cute and Interesting Kitten Kittens were very charming little animals. After careful observation, one would find that they had many unique characteristics. From its appearance, the kitten's eyes were very eye-catching. During the day, their eyes often narrowed into a thin line, like a thin thread. At night, the pair of eyes became big and round, like two crystal clear gems, shining with a mysterious light in the darkness. This was because cats 'eyes had a special structure that could adapt to different light intensity. Their ears were always alert, like two sensitive small radars. No matter how soft the sound was, it could not escape their ears, which helped them capture the movements around them, especially the sounds of prey. The kitten's mouth was small and cute, pink in color, and the sound of "meow" was very clear. There were many small thorns on the surface of its tongue, and these small thorns had special functions. The behavior of the kitten was also very interesting. Most of them were very lazy and slept for a long time in a day. They either curled up in their own nests or found a sunny place to lie down. But when they found something interesting, they would immediately become smart. For example, when they saw a mouse or a cat teaser, they would quickly pounce on it. Their movements were agile and light, just like an excellent little hunter. The kitten was also very greedy, especially when it came to fish. As long as they smelled the fishy smell, they would run over impatiently. I once saw a kitten. As soon as the owner put the fish on the table, the kitten jumped onto the table and ate the fish. That greedy look was both funny and cute. Kitten's body language was also very rich. When it made a purring sound, it might mean that it was hungry; if it bent down, it meant that it was in an attacking posture and ready to pounce on its target; if it wagged its tail, it meant that it was very happy at the moment; and when it lay on the ground, it might be listening attentively to the mouse's movements. In short, kittens were charming little animals. Whether it was their unique appearance or interesting behaviors, they were worthy of our careful observation and in-depth understanding.

An observation diary was a type of diary that recorded the changes of the object of observation over a long period of time. The objects of observation could be plants, animals, celestial bodies, and so on. When writing an observation diary, one must first identify the object of observation and directly explain it at the beginning. For example, during the process of observing the sprouting of green beans, green beans were the object of observation. The middle part recorded the changes of the observed objects in a temporal order. For example, green beans might be dry and hard on the first day. After soaking, they might gradually grow fat, break the skin, grow small buds, and the small buds would continue to grow longer and thicker. At the end, he could write about his own gains and express his love for observing things. Through the observation of the sprouting process of mung beans, one could experience the magic of life growth, thus expressing their love for the tenacious vitality of mung beans.

Planetary observation is an interesting and scientific activity. Here are some key points about planetary observation: * * I. Observation Equipment ** 1. * * Binoculars ** - Different planets might require different binoculars. For example, to observe Jupiter, a telescope that magnified 20 times would allow the observer to see that Jupiter was slightly oblate. If one wanted to see the bright band of Jupiter's atmosphere, a telescope with a higher magnification was needed. - For high-power planetary observation, there were specialized eyepieces to choose from, such as the 82-degree 4.7mm ultra-wide-angle planetary eyepieces produced by Nanjing Boguan Astronomical Factory. It was suitable for observing planets such as the Moon, Mars, Venus, as well as Saturn's rings and Jupiter's stripes. It had an all-metal structure, a 1.25-inch standard interface, and was suitable for astronomical telescopes. 2. * * Other auxiliary tools ** - For beginners, a compass and a red flashlight were basic tools for stargazing (including planetary observation). The compass could be used to identify directions, and the red flashlight could provide a certain amount of illumination during night observation without overly affecting the eyes 'ability to adapt to the dark environment, thus not affecting the observation effect. * * 2. Observation timing ** 1. * * Mercury * - The best time to observe Mercury was about 50 minutes before sunrise or 50 minutes after sunset. When Mercury is furthest from the sun on one side or the other of its orbit, it is easier to find it before sunrise or after sunset. The astronomy app could tell whether the distance was to the west (right) or east (left) of the sun. If it was to the west, it could be observed in the morning; if it was to the east, it could be observed at dusk. It could be observed for about two weeks before it was submerged by sunlight. After six weeks, it would reappear at the opposite angle. Because Mercury was often submerged in the sun's brilliance, it was difficult to see it a few times a year. 2. * * Venus ** - When Venus was in the west (to the right of the sun) or the east (to the left of the sun), it was a good time to observe. The best time to observe it was probably when the sun was just below the horizon. When Venus was in the shape of a large crescent moon, it was more suitable to observe it with binoculars. At this time, Venus was located between the maximum angle point and the lower conjunction point. Venus is located between the Earth and the Sun and cannot be seen. 3. * * Mars * - When the Earth was between Mars and the Sun (Mars opposition), it was a good time to observe Mars. When the sun set in the west, Mars was rising from the east. Mars was above the horizon all night. The best time to explore it was just after the sun set in the west. Mars opposed the sun once every two years and two months, but only every 15 to 17 years would there be an ideal time to observe it. For example, such an opportunity appeared in 2003, but with excellent telescopes and Mars's own red light, it could be observed in most years. 4. * * Jupiter * - Jupiter was in opposition to Earth every 13 months, so it was easier to observe at this time. Jupiter was very bright, three times brighter than the brightest star, Sirius. It was easy to find Jupiter with a star map. 5. * * Saturn * - Since Saturn was very far away from Earth, it was not easy to find it, but as long as one found it, they would not mistake it. * * 3. Observation location and environment ** 1. * * Light pollution ** - Stargazing (including planetary observation) must first avoid light pollution. You can check the distribution map of light pollution, try to avoid red and yellow areas with dense light pollution, and choose gray and blue areas. If you live in a farmhouse, you can observe in the yard or on the roof. When observing, you need to turn off the nearby lights. If you are camping in the wild, you should choose a place with an open line of sight and not too many obstacles around to observe. When observing in the wild at night, it is best to be accompanied by family and friends to ensure safety. 2. * * Moon phase effect ** - Moonlight would illuminate the night sky, especially in the days before and after the full moon. The bright moonlight would obscure the stars. Therefore, if one wanted to enjoy the fun of planetary observation, it was best to choose a day without the influence of moonlight. Usually, the first five days before and after the first day of the lunar calendar were the best days to observe the stars, followed by the second half of the night before the ninth day of the lunar calendar, and the first half of the night after the twenty-first day of the lunar calendar was also a good day to observe the stars. 3. * * Weather factor ** - It was best to choose a sunny day for observation. Before departure, one had to accurately check the weather conditions on the day of the destination and the next few days in order to formulate an observation plan. * * 4. Observation Method ** 1. * * Locating a planet with a star map or an app ** - In an environment without the influence of light pollution, planets could be found through star maps or mobile apps (such as Google Star Map, Skychart, and Star Map). These apps, coupled with the phone's sonar function, could also display the planets in the direction they were pointing in real-time. 2. * * Planet identification by special phenomena or characteristics ** - For example, Jupiter was very bright and emitted a stable yellow light. The Galilean satellite was orbiting in a thin line on Jupiter's equator, appearing as a bright spot on its orbit. Venus was one of the brightest celestial bodies in the sky. It was bright and slightly yellow. These characteristics helped to identify planets in the starry sky. * * 5. Planet discovery method (helps to understand the scientific principles of planetary observation)** 1. * * Pulsar timing method ** - When the pulse signal of the high-speed rotating neutron star swept across the Earth, if there were planets around the pulsar, the planets would cause gravitational disturbances to the pulsar, causing the pulse signal emitted by the pulsar to be abnormal. In 1990, scientists discovered three planets around the pulsar named PSP B1257 + 12. 2. * * Planetary transit method ** - When a planet passed between the mother star and Earth, part of the light emitted by the star would be blocked by the planet, causing the star's brightness to change periodically. Kepler used this method to conduct long-term observations of approximately 100,000 stars in Lyra and Cygnus, obtaining data on nearly 150,000 stars and discovering more than 3000 extraterrestrial planets. 3. * * Radial-Speed Method ** - Planets orbit around the star and produce traction force. When the star is pulled in a radius, the light emitted by the star will have a blue shift or a red shift (the Dopplar effect of light). This phenomenon can be used to infer the existence of planets and determine the speed, mass, orbital radius, and revolution period of the planet. 4. * * Gravitational Perturbation Method ** - Using the gravitational pull effect of the planet on the star, if the star was not far from the Earth, then the gravitational disturbance of the star could be directly observed from the telescope. 5. * * Relativistic Method ** - As the planet revolved around the star, it would have a drag on the star, causing the brightness of the star to change slightly. This method was suitable for finding massive planets. 6. * * Gravity Microlens Method ** - The general theory of relativity showed that space-time bending would occur around celestial bodies, and space-time bending would also occur around stars and planets. Therefore, the light emitted from the surface of the star would produce a first light curve, and if it passed around the planet again, it would produce a second light curve. This method could be used to discover some extraterrestrial planets, even rogue planets. 7. * * Direct imaging method ** - When the planet was far away from the parent star, the light reflected by the planet could be separated from the light of the parent star. The planet could be observed directly and the detailed parameters of the planet could be obtained. However, this method had extremely high requirements for the observation equipment. It also required the size of the planet to not be too small. The closer it was to Earth, the better. At the same time, the planet could not be too close to the parent star. The novel "Mars of Paradise" is equally exciting. Everyone is welcome to read it!

The following is an example of a weekly diary about observing kittens: [Weekly Observation of Kittens] In the past week, I had a new observation and understanding of the cute kitten in my neighbor's house. The kitten's appearance was very eye-catching. Its entire body was furry, and its fur was as white as snow. There was only a small patch of faint gray fur on the tip of its ears, like a little frost in winter. Its eyes were like deep lake water. Its blue eyes were clear and bright, like two sparkling gems in the darkness. In the middle of her eyes was a small and pink nose that kept sniffing around, full of curiosity about everything around her. It had a small mouth, and the corners of its mouth always had a subtle smile. There were also a few slender whiskers on both sides of its mouth, like a sensitive detector. Kitten had a lively and mischievous personality. Every morning, when the first ray of sunlight shone into the courtyard, it was like an energetic little furball. It began to run around the courtyard, chasing its tail, round and round, as if it was the most interesting game in the world. It was interested in everything. A falling leaf could also become its toy. It would gently fiddle with the leaf with its claws, then suddenly pounce on it and press the leaf tightly under its claws. It would also look up from time to time to see if there were other " little friends " who would snatch its " spoils of war." Its eating habits were also very interesting. Kitten was a gluttonous cat and especially liked to eat canned fish. Whenever its master approached with a can of fish, it would immediately run over and circle around its master's legs. Its mouth kept making soft meowing sounds, as if to say," I can't wait anymore." Once it ate the canned fish, it would squint its eyes and savor it carefully. Its small mouth chewed quickly, and soon, the fish in the canned fish was completely destroyed by it. This kitten was also very smart. Once, it accidentally got the ball under the sofa. Instead of blindly scratching and hitting it, it first lay on the ground, tilted its head, and carefully observed the position of the ball with its eyes. Then it stretched out its small claws and carefully hooked the ball out from under the sofa. This week's observation made me like this kitten even more. It was like a lively and mysterious elf, bringing endless joy and warmth to the people around it.

[Green Bean Germination Observation Diary] [Date] Sunny Today, I began my journey of observing the sprouting of green beans. I picked out some plump green beans. They were small and hard to the touch. Their skin was smooth and dark green, like mini emeralds. I put the green beans into the bowl and added a suitable amount of water. The water just covered the green beans, as if covering them with a thin layer of transparent quilt. The next day, Green Bean became chubby like a baby who had drunk enough water. Many green beans broke through their green coats, revealing their white bellies. In the middle, there were also little white buds that appeared like small commas. These small buds were extremely delicate. A few days later, the green bean sprouts had grown quite a bit, about one or two centimeters long. Some of them were straight, some were curved, and they had different shapes. Most of the green bean skin had fallen off, as if the green coat had been thrown far away. As time passed, the green bean sprouts grew uniformly, like a small forest. Each root was thin and tender, as if it would break with a pinch. Watching these green beans grow from small seeds to bean sprouts, his heart was filled with surprise. The growth of life was really full of miracles.
