2. Time: It is the time to observe nature this time. Different years and seasons have different phenology, so the recording time is helpful for comparative study.
3. Location not only helps to find the law, but also helps yourself or others to find the location again for observation. Different species in different regions, the same species has different phenotypes or behaviors in different regions.
4. The natural phenomena under different weather conditions are very different, and only by recording them can we summarize and discover the laws.
Like scientific observation, natural notes are objective observation records of nature, but under the influence of people themselves, everyone's notes are subjective. According to the recorder, we can make a basic judgment on the objectivity of the notes, or we can contact the recorder for further communication.
6. The theme is a summary of the content of natural notes. The topic name should be cool enough to attract readers first. It is better that the subject is not the scientific name of the observed object. For example: the magical ryegrass, the master climber in plants, etc.
7. Words are the main body of natural notes. As long as we observe nature from multiple angles with vision, touch, smell, hearing and other senses, we can get a lot of observation contents to record. The description of natural phenomena should be as objective as possible without any exaggeration. Due to the lack of professional vocabulary, metaphor can be used to describe features or phenomena. Pinyin can be used for words that can't be written, and students are encouraged to write. Emotional statements and unfounded speculations can't appear in natural notes, such as "the grass is so green because it has been honed in the cold winter" and "the plumeria has no elegant temperament and noble fragrance ...". It does not belong to the phenomena observed at that time or the results of measurement, statistics and experiments at that time, such as "Iris is the national flower of Germany" and "the surface temperature of the sun is 6000℃".
8. Pictures are a supplement to written descriptions and an intuitive presentation of natural phenomena. Pictures should be as realistic and objective as possible, not exaggerated, exaggerated or abstract. Natural objects in the picture must have scale or size data, and no scale can be estimated by fingers, pens, footsteps, trees, buildings, etc. For the details of natural objects, we should use "enlarged pictures" to express them. There can be no impersonal depictions such as cartoon modeling in the picture, and there can be no superfluous operations such as drawing eyes on fruits and lace on leaves. There is no need for artistic rendering effects such as background color and shading.
