2. Ask for an essay about biological science.

Since 1982 was held in Shanghai, the national youth invention and science seminar has been held every two years. Up to now, it has lasted for 10 (renamed as the National Youth Science and Technology Innovation Conference from the tenth session in 2000), and it has become a traditional project of science and technology activities in primary and secondary schools and an important part of school education.

Many students' excellent works have been published in national newspapers and periodicals, and some have won prizes in the country and even internationally! 1. What is a scientific paper? Some students regard writing scientific papers as mysterious, thinking that it is a scientific job to get rid of general Ishikawa, which is beyond our children's reach. This is a complete misunderstanding. Students can not only write, but also write high-quality papers.

Scientific papers written by scientific workers refer to scientific research reports written by the author through experiments, observation and other means, and then through analysis and research according to the scientific research projects and determined scientific research topics. The scientific papers written by students are shorter and shallower than those written by scientists.

In fact, a scientific paper is a written summary of the achievements made by students through scientific observation, experiment or investigation in extracurricular scientific activities. Its manifestations are various: it can be a conclusion drawn after careful observation and in-depth thinking about something; It can be the conclusion of analysis after hands-on experiment; It can also be a summary after a local investigation; You can also draw a conclusion through logical reasoning ... So, are there any quality standards for scientific papers? Yes

It must have "three characteristics". 1, science.

Scientificity is one of the important characteristics that distinguish scientific papers from other genres, and it is the life of scientific papers. It requires scientific topics, correct research methods, conclusive arguments, reasonable and logical arguments, and concise and accurate words.

2. Creativity. The topic selection and main viewpoints of small papers should have their own new discoveries and unique opinions, which have certain practical significance to people's production and life. The same small paper has not participated in scientific seminars at all levels, nor has it been published in newspapers at all levels.

Of course, if you further study on the basis of other people's research, it is also feasible and creative to put forward novel, unique and fully demonstrated views. 3. practicality.

The title of the paper must be discovered by the author himself in scientific exploration activities; The arguments supporting the main points must be obtained by the author through observation, investigation, experiment and other research methods, and have practical basis; The paper must be written by the author himself. There can be no signs of fabrication, speculation or adult substitution.

The above "three natures" are the quality standards for measuring scientific papers. If you write Sunflower, although your observation is meticulous, your posture description is vivid and your character analysis is perfect, if you can't get a scientific and meaningful conclusion, it can only be regarded as a good essay or observation diary, not a scientific essay.

Writing scientific papers is a very hard work and a very meaningful activity. Success belongs to young friends who are brave in exploration and unremitting pursuit! Types of scientific papers The most common forms of scientific papers are scientific observation papers, scientific experiment papers, scientific investigation papers and scientific explanation papers.

(1) scientific observation composition refers to teenagers' careful observation of a certain thing or natural phenomenon, careful analysis and comprehensive study of the obtained materials and data, and then draw conclusions and make scientific explanations and explanations. Liu Hao's father in Hunan often coughs. Through long-term and repeated observation, he found that the wind direction has a very close relationship with his father's cough, and found out the "culprit"-a large amount of smoke from the chimney of Hunan Rubber Factory, which contains sulfur dioxide. As soon as his father smelled it, his throat was allergic and he coughed reflexively.

His essay "Dad's Cough" mainly draws a conclusion by observing this research method, which belongs to scientific observation prose and won the third prize of the second national youth science seminar. It should be noted that the research object in scientific observation essay is an objective natural thing or phenomenon, which occurs under the condition of natural light and is not controlled by human beings, so the content described in this paper should be the object, process, conditions and various phenomena observed by the author, and no artificial conditions or personal prejudice can be attached.

In addition, observation is a long-term, systematic and repeated activity, which requires the patience, meticulousness and perseverance of the author. (II) Essays on Scientific Experiments Essays on scientific experiments, sometimes called "experimental reports", are articles in which teenagers create specific conditions for the research objects, analyze the obtained materials and data after repeated experiments, and draw comprehensive conclusions.

It focuses on the objective description of the experimental process and the scientific explanation of experimental phenomena. Parthenocissus can climb the wall, which is known to many students.

But why can Parthenocissus climb the wall? Xiong Bin, a student in Wuhan, found through observation that this is related to the "tentacles" of Parthenocissus tricuspidata. Then he estimated that there were 25 "tentacles" attached to the wall on the average one-meter-long stem of Parthenocissus tricuspidata, and made an experiment of "measuring and adsorbing the tension of tentacles". The purpose of the experiment is clear, the experimental steps are detailed, the data are accurate, the explanation is strong, and the conclusion is true and credible. It is an excellent scientific experiment essay. (3) Scientific Investigation Essay If you want to study the pollution degree of a certain water area closely related to people's life, the air pollution source of a certain place, and find out the evolution process, animal and plant resources and distribution of strange rocks and mountains in a certain range, you have to make a field trip.

A small paper written through investigation, interview and field investigation is called a scientific investigation small paper. Sometimes it is also called "scientific investigation report" and "scientific investigation report".

In the article "Evergreen Water of Zhushengtian Reservoir", which won the first prize in the 5th National Youth Science Symposium, the author made a field investigation on the geographical and ecological environment and water storage capacity of the reservoir, and made a field measurement as far as possible, found out the hidden dangers of the reservoir and put forward more reasonable suggestions. This paper expounds the time, object, content and conclusion of the comprehensive analysis, and draws the "Rain Collection Map of Shengtian Reservoir" and "Strong Erosion Diagram of Zhongshan City".

3. How to write a biological paper

There are many creatures in the world, and the world is wonderful because of life. Biological forms are different and interesting, for example, dancing butterflies, annoying flies, lovely birds that can sing, and dinosaurs that died out 65 million years ago. All their signs of life attracted my attention and made me curious about biology.

My previous understanding of "biology" was simply "animals". I have studied biology in middle school and know that biology covers a wide range, not only animals, but also plants and microorganisms. There are about 300,000 kinds of plants and 1.5 million kinds of animals on the earth. I learned some unusual plants from biology books, such as spinulosa spinulosa, fern and cycad, and also solved some problems that I didn't understand when I was a child. Once, I dug earthworms in dry soil, but I couldn't. Now I know that earthworms live in dark and humid places, and of course they can't dig in dry soil. Why do cactus leaves degenerate into thorns? Because of the need to adapt to the environment, in order to reduce the loss of water and store more water, the stem of cactus has become thick and juicy. Biology helped me understand the problem, which is one of the reasons why I like biology.

Walking into the second unit, I learned about the microscope. In my mind, the microscope is so wonderful that I always want to use it to observe things. I haven't touched it in elementary school. I remember the first time I entered the biology laboratory and saw the microscope on the table. I feel an uncontrollable joy. So I couldn't wait to look at the eyepiece, but all I could see was darkness. In class, the teacher said that observing things with a microscope is not as simple as expected, and it takes several steps, such as aiming at the light, selecting the objective lens, making temporary slide specimens and adjusting the clarity. I listened carefully, trying to remember every structural name. With the help of the teacher, I finally saw the cells through the microscope. At that time, I felt a sense of accomplishment, as if I had become a scientist and could observe microorganisms with a microscope! There is also a strange phenomenon, which is inverted under the microscope. Nowadays, using a microscope has become a common practice, and experiments have to be done in almost every class. Observing things invisible to the naked eye with a microscope can make me happy and stimulate my interest in learning biology.

In addition, I have a new understanding of organisms. All living things are made up of cells except viruses. The cells seen under the microscope are arranged one by one. Plant cells are composed of cell walls, cell membranes, vacuoles, nuclei, mitochondria, cytoplasm and chloroplasts, while animal cells are composed of cell membranes, cytoplasmic nuclei and mitochondria, and their functions are also different. The nucleus is made up of chromosomes, and chromosomes are made up of DNA ... Don't underestimate a small life, its structure is very complicated! I didn't know where the water in the fruit came from before, but from the fine vacuoles in the vacuoles. I'm always sick. After learning biology, I realized that the virus was playing tricks on me! Even viruses are creatures, which is incredible! I'm getting more and more curious about biology.

Biology brought me into a wonderful world. Solving difficult problems broadens my mind. Using a microscope makes me happy. Microbes make me curious. Therefore, I have a strong interest in biology.

4. Senior high school biology composition,

Selected papers on senior high school biology

Biology is an important course in senior high school, and efficient biology teaching is helpful to improve students' biological knowledge and skills. The following is a small senior high school biology paper that I arranged for you for your reference.

High school biology model essay: the countermeasures to cultivate students' innovative ability in high school biology teaching

Innovation ability is the ability to achieve innovation results through innovation activities. In biology teaching, teachers pay attention to the cultivation of students' innovative ability, which meets the needs of current quality education. Implementing inquiry learning in senior high school biology teaching can arouse students' learning initiative and stimulate their interest in learning biology, thus laying a good foundation for initially cultivating students' innovative consciousness.

First, high school biology teachers pay attention to mobilizing students' enthusiasm for learning biology.

In order to effectively mobilize the enthusiasm of high school students to learn biology, it is necessary to make them curious about the learning of biology knowledge in high school. Biology teachers should make full use of students' curiosity about knowledge, turn high school students' curiosity into students' thirst for knowledge, fully stimulate students' interest in learning, and become the internal motivation of students' learning.

For example, in order to attract students' interest in learning, biology teachers in high schools designed an experiment-"photos of leaves" when talking about the knowledge of plant photosynthesis. The biology teacher instructed the students to fix the negative of the photo on the young leaves, but only when the plants can receive sunlight can photosynthesis be carried out. In a few days, remove the negative film, take off the leaves, put them in boiling alcohol, take them out after the leaves become lighter, put the discolored leaves in a Petri dish, add a few drops of iodine, and photos will appear on the leaves, which is what I said. Third, senior high school biology teachers should pay attention to the cultivation of students' problem consciousness. In short, senior high school biology teachers should pay attention to the cultivation of students' problem consciousness.

Little knowledge of biology

Hermit crabs can be seen everywhere from the dark deep sea to the rapids. There are also terrestrial hermit crabs, which live in humid forests far from the sea in South America. During the breeding season, these hermit crabs crawl to the coast in droves and give birth in the sea. When the little hermit crab grows up, it migrates to the dense forest.

Hermit crabs can inhabit the shells of any gastropod. If there is no empty shell, the hermit crab will attack, tear its owner out of the house piece by piece, move in by itself, and then it will block the entrance of the shell with an aojiang. But some fierce animals in the ocean are not afraid of the big claws of hermit crabs. Octopus, for example, is not afraid. Octopus can easily break into houses with powerful wrists and pull hermit crabs out of their shells. In order to guard against the attack of robbers, hermit crabs have a special weapon, that is, to find the "poisonous flowers" on the seabed-anemones, and live with anemones.

The toxicity of anemone is close to that of curare. A little anemone toxin can kill a jaguar. Animals in the sea try to avoid anemones. They are all afraid of these "poisonous flowers". This is of great benefit to hermit crabs, because anemones can be their voluntary guardians. Hermit crabs and anemones live together, which is really a wonderful life.

There are more than 400 species of hermit crabs known in the scientific community, but their relationship with anemones is not the same. The relationship between the real hermit crab and the warty anemone can be said to be dependent on each other. If separated, the warty anemone will die in two or three months, and the real hermit crab will be eaten by greedy crabs or octopus in a few days because it is not protected by the venom of the warty anemone.

Real hermit crabs don't put anemones on the roof of their homes like other hermit crabs, but under the "threshold"-the shell entrance. The pores of the wart anemone are like the cannon holes of the fortress, from which poisonous "arrows" can fly out and shoot at the enemies who invade the real hermit crab. The mouth of the wart anemone is behind the mouth of the real hermit crab. When the crab eats, the wart anemone eats with it-it grabs the shredded food of the real hermit crab with its tentacles.

Some hermit crabs directly carry anemones on their backs; Some hermit crabs also put the anemones they found in their big claws to seal the door. In this way, the octopus dare not venture into its home.

Sea crabs inhabiting coral reefs in the Indian Ocean have anemones on each claw and are regarded as excellent weapons. When fierce animals in the sea open their mouths to eat sea crabs, the sea crabs will present this bunch of "flowers of the sea", which will make the enemy's mouth ache like fire and run away quickly.

6. A 500-word biology essay

Why is the trunk round? In the process of observing nature, I happened to find that the shape of the trunk is almost round-an empty cone. Why is the trunk conical? What are the benefits of a conical trunk? In order to discuss these problems, I have made more in-depth observation, analysis and research. With the help of my tutor, I consulted relevant materials and learned that the stems of plants support plants and transport water and other nutrients. The stems of trees are mainly composed of vascular bundles. The supporting function of stem is mainly borne by xylem wood fiber. Although the stems of woody plants will thicken year by year, the number of woody fibers in the stems is fixed in a certain time range, that is, the cross-sectional area of the stems is fixed. Then, we design experiments around the cross-sectional area of the trunk, assuming that the cross-sectional area of the trunk grows into different shapes, and explore the reasons and advantages of the conical trunk. Through experiments, we found that: (1) under the condition of certain cross-sectional area and length, the vertical supporting force of triangular columnar objects is the largest and the lateral bearing capacity is the smallest; The vertical supporting force of cylindrical objects is not as good as that of triangular cylindrical objects, but the lateral bearing force is the largest; (2) For trunks with the same mass and different shapes, the short conical trunk bears the largest wind force; (3) Wind is a natural phenomenon, which affects the cross-sectional shape of trees and the height at which trees grow. The cone-shaped trunk has a lower center of gravity, and the huge root system is connected with the earth, which makes the center of gravity lower and more stable. (4) The cross section of the trunk is round, which can reduce the damage, and has stronger mechanical strength and can resist the wind attack. At the same time, under the action of wind, the bending degree of the trunk is almost everywhere. No matter which direction the wind blows, the resistance of the trunk is similar, and the trunk is not easy to be damaged. The above experiments reflect the laws of nature, and the enlightenment of nature is that (1) the vertical supporting force of a cylindrical object with a triangular cross section is the greatest. (2) A circular object with a circular cross section has the largest lateral bearing capacity, and similar building materials can be found everywhere, such as TV towers and telephone poles. In the process of observation, experiment and analysis, I gradually explained and revealed the mystery of conical trunk, which increased my knowledge. Combining what I have learned with practice, I not only consolidated what I have learned, improved my interest in learning, but also learned the scientific observation and analysis methods.

A small paper on water saving

Water is an ordinary thing. Everyone has it. Although water is common, it is absolutely indispensable in life. One day without water, one will die of thirst. In other words, water is an important part of natural resources, the structural composition of all living things and the main material basis of life activities.

Water also contributes a lot to the factory, for example, it can be used for hydropower generation.

There are few water resources available on the earth, but in our daily life, water is wasted everywhere. Some people who live by the river dump piles of garbage into the river in order to walk less, making the river dirty and smelly, so that we can't drink pure water. In addition, the phenomenon of wasting water in some construction sites is more prominent. Often, several faucets are unscrewed continuously, so that the tap water keeps flowing; Some irresponsible people turn on the tap all day and let the water overflow. These phenomena of wasting water are not uncommon.

Last week, I went to my uncle's house, and my cousin was there. When I saw that I washed my hands before eating apples, my cousin was probably because he was small and weak. Wash well, the tap is not turned off, and the water is still dripping. Fortunately, I turned off the tap in time, so the water didn't continue to flow.

When I came back from my uncle's house, I thought, "Water resources are so poor that people still waste them like this. I don't know how much precious water resources to waste! " I have another picture of the faucet dripping in my mind. I also thought: If children forget to turn off the water when washing their hands or doing other things, adults and others don't know about it, how much water will be lost?

In my opinion, saving water is not just talk. To really do it in action.

8. Essays on Biological Science Popularization

"Why can't fish live without water?"

"Fish Breathing" is the teaching content in the first volume of the eighth grade of the new biology textbook published by People's Education Press. After careful analysis of teaching materials and standards, I think that the experiment on fish breathing can improve students' interest in learning, cultivate students' various abilities and improve their biological science literacy. Therefore, the theme of this lesson is why fish can't live without water. In order to fully arouse students' interest, a series of inquiry experiments were designed, and related courseware and teaching AIDS were made to help students explore the reasons why fish cannot live without water.

First, the teaching objectives

Knowledge goal: Through teaching, let students know the position, morphological structure and physiological characteristics of gills, and then understand why fish can't live without water.

Ability goal:

1. Further cultivate students' experimental operation ability of correctly using common tools and instruments such as microscope through experiments.

2. Through teaching, students can learn to use their own biological knowledge to analyze and solve practical problems in life and production.

3. Cultivate students' observation ability, thinking ability, experimental ability, self-study ability and drawing ability through inquiry learning activities.

Emotional attitude and value goal;

1. Through students' experiments, further cultivate students' scientific attitude of seeking truth from facts, certain exploration spirit and innovative consciousness.

2. Starting from common life phenomena, guide students to explore and experiment, so that students are willing to explore the mysteries of life.

3. Let students apply what they have learned and realize the value of life science.

4. Further cultivate students' sense of unity and cooperation through students' cooperative experiments.

5. Further help students to establish dialectical materialism that is compatible with structure and function.

9. The importance of biological knowledge in daily life

Like fermentation (yogurt, steamed bread, rice wine ...)

Another example is living and eating habits (the biggest example is not eating junk food)

There are also advertisements to prevent people from being cheated. Advertisements for weight-loss products like to use ordinary people's ignorance of biological common sense, and even fabricate lies to mislead consumers. There is also a classic advertisement for rare nucleic acids. What supplements the nucleic acid needed by the human body will also increase the resistance. What a liar! )

There is also understanding your body and how to live a healthy life (sensory and medical aspects)

There are more than n, so I won't say much here.

If you want to write a paper, it's only a spoonful if you fall into the water. Don't write too miscellaneous. Take a little to discuss in depth. It is estimated that you can get a good result!
