biology content writing

High school biology experiments usually included the following important parts: ** 1. Experiment Title ** The main content of the experiment should be clarified, and the core content of the experiment should be summarized concisely, such as "exploring the effect of temperature on the activity of the enzyme". ** 2. Experiment Purpose ** 1. ** Knowledge target ** - Explain the biological knowledge concepts to be understood or verified through experiments, such as "understanding the principle of the effect of temperature on the activity of an enzyme". 2. ** Ability Target ** - He explained the skills to be trained during the experiment, such as "mastering the application of the variable control method in the experiment, learning to use specific experimental instruments for measurement and observation", etc. ** 3. Experiment Principle ** 1. ** Biological Principles ** - Explain the basic biological principles that the experiment is based on. For example, in the experiment of "Observing the plasmatic separation and recovery of plant cells", the principle is that the protoplasma layer of plant cells is equivalent to a semi-transparent membrane. When the concentration of cell fluid is lower than the concentration of the external solution, the cell loses water and plasmatic separation occurs. When the concentration of cell fluid is higher than the concentration of the external solution, the cell absorbs water and plasmatic separation occurs. 2. ** Principle of related technology (if any)** - If special technical means were involved, such as dyeing techniques, the principle must be explained. For example, in the experiment of "Observing the distribution of DNA and DNA in cells", the affinity of methy-green and pyro red stains for DNA and DNA was different. methy-green made DNA appear green, and pyro red made DNA appear red. ** 4. Experimental Materials and Tools ** 1. ** Experiment Materials ** - List the biological materials used, including the types and parts of the organisms. For example, in the experiment of "Observing the Mitosis of Plant Cell", the materials were onion root tips (onions, garlic). 2. ** Experiment Tools ** - Write down in detail the required instruments, reagents, etc., such as microscope, slide, cover glass, disintegration solution, gentian violet dye solution, etc., and indicate the necessary information such as the concentration of the reagent. ** 5. Experimental Steps ** 1. ** Preparing Stage ** - This included the pre-treatment of the experimental materials, such as the cultivation of onion root tips in "Observing the mitosis of plant cells"(3 - 4 days before the experiment, place the onions on a wide-mouthed bottle filled with water, the bottom of which is in contact with the water. The device is placed in a warm place, and pay attention to changing the water frequently. The purpose is to prevent the roots from rotting. Wait until the roots grow to 5 cm). 2. ** Operation procedure ** - Each step of the operation was described in detail in order, including the actions of the operation, the amount of equipment or reagents used, etc. For example, in the experiment of "making and observing the temporary mounting of the onion scale leaf inner skin cells", the rubbing was done.(Wipe the slide clean with a clean gauze, then take a cover glass and wipe it clean. Put the cover glass on one end of the slide for later use.)(Drip 1 - 2 drops of water in the center of the slide with a dropper)(Take a piece of onion scale leaf, cut a small square about 0.5 cm with a blade on the inner skin, and then tear a small piece of transparent film with tweezers)(Dip the peeled inner skin into the water droplets on the glass slide and flatten it with tweezers), cover (use tweezers to pick up the cover glass so that one side of it touches the water droplets on the glass slide first, then slowly put it down and cover it on the material to be observed), dye (then drop a drop of the solution of the solution of 3. ** Points to note ** - During or after each step, the points that needed special attention were indicated. For example, when using a microscope for observation, it was necessary to pay attention to the low power microscope before the high power microscope; when making temporary mounting, it was necessary to keep the experimental materials moist. ** 6. Experiment result ** 1. ** Anticipated result ** - According to the theory and purpose of the experiment, he could deduce the possible results. For example, in the experiment of "exploring the effect of temperature on the activity of an enzyme", if the temperature was within a suitable range, the activity of the enzyme would be higher and the reaction speed would be faster; if the temperature was too high or too low, the activity of the enzyme would decrease, and the reaction speed would slow down or even stop. 2. ** Real-world result (if the experiment has been completed)** - An objective description of the phenomena observed or the data measured during the experiment can be presented in the form of tables, charts (such as bar charts, line charts, etc.), or text. ** 7. Experiment conclusion ** 1. ** Analysis of the results ** - To analyze the experimental results and explain the reasons for the results. For example, in the experiment of "Observation of plasmatic wall separation and recovery of plant cells", the cell structure and physiological mechanism of plasmatic wall separation or recovery were analyzed. 2. ** Come to a conclusion ** - According to the analysis of the results, the final conclusion of the experiment should be summarized. The conclusion should be closely related to the purpose of the experiment, such as "temperature has a significant effect on the activity of the protein. Within a certain range, the activity of the protein increases with the increase of temperature. After exceeding the optimal temperature, the activity of the protein decreases with the increase of temperature." ** 8. Analysis of errors (if any)** 1. ** Source of error ** - Find out the factors that may cause the experimental results to be inconsistent with expectations, such as the accuracy of the experimental instrument, the individual differences in the experimental materials, and human errors in the operation process (such as errors in measuring reagents, etc.). 2. ** Modification measures ** - In view of the source of error, the improvement methods were proposed, such as improving the accuracy of the instrument, increasing the number of experimental samples to reduce the influence of individual differences, and regulating the operation process. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

"A Biology Teacher's Experience." In the long journey of biology teaching, I gained a lot of valuable experience and profound insights. 1. Change of Concept In the past, under the influence of exam-oriented education, I limited the focus of biology teaching to the completeness and systematic nature of knowledge. The purpose of teaching was purely to let students master knowledge and obtain high marks. However, as I learned more about the new curriculum, I realized the narrowness of this concept. Junior high school biology education should be for all students, aimed at improving the biological science accomplishment of all students. This requires us to cultivate students 'passion for nature and the protection of the environment, and to increase their interest in biological science. Our teaching design and activity arrangement should be student-centered, with the cultivation of basic quality as the core idea, and pay attention to the selection of extra-cursory knowledge closely related to student life. Teachers should not only impart knowledge, but also guide and promote the development of students. Knowledge is only the carrier of cultivating students 'quality. The new textbook's content, such as the exploration process of biologists, helped students establish a scientific outlook on life and the world. Although the parts such as "extra-cursory reading" and "research study" were not the focus of the exam, they were of great significance to cultivate students 'scientific quality and sustainable development ability. Second, the reform of teaching methods Under the guidance of the new curriculum standards, I actively explored new teaching methods. In the past, the "structured" and "closed" teaching models were abandoned and replaced by "non-structured" and "open" teaching models. I tried my best to use inquiry-based teaching to stimulate students 'interest in learning biological knowledge. For example, a series of scientific inquiry activities were arranged in experimental teaching, which increased the space for teaching design, increased student participation, varied classroom teaching forms, active atmosphere, and more ideal teaching effects. The key points in teaching practice 1. Consolidating Basic Knowledge The basic knowledge of biology in junior high school, such as basic concepts, principles and laws, was the key to teaching. This was like the cornerstone of building a house. Only by mastering the basic knowledge could students better understand and apply the knowledge. In teaching, I will use a variety of methods, such as repeated emphasis, questions and answers, after-class exercises, etc., to help students consolidate their knowledge and achieve the effect of mastery. 2. practical ability Biology was an experimental science, so it required students to have practical abilities. I focus on letting students experience the fun and charm of biological experiments through hands-on operation, cooperative communication, reflection and summary. In this process, the students 'hands-on operation ability, communication ability, and rigorous and serious exploration spirit were cultivated. 3. Arouse one's interest in learning Biology teaching in junior high school needed to stimulate students 'interest and curiosity, and encourage them to learn independently. I will create a problem situation to stimulate the students 'curiosity. At the same time, I will use multi-media and interaction games to let the students feel the fun and practicality of biology, thus stimulating their learning motivation. In short, biology teaching is a process of continuous exploration and innovation. We need to continue to pay attention to these aspects in teaching to cultivate students 'biological literacy and comprehensive ability. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Here are some content suitable for the second volume of the seventh grade biology handwritten report: ** 1. Blood transfusion and blood type ** 1. Blood type: discovered by Austrian scientist Karl Landsteiner, it has hereditary characteristics. 2. The principle of safe blood transfusion: Generally, the principle of blood transfusion of the same type is followed. However, in an emergency, patients with type A blood could slowly transfuse a small amount of type O blood. For healthy adults, donating 200 - 300 milliliters of blood each time would not affect their health. For voluntary blood donation, they had to meet the conditions of being 18 - 55 years old, healthy, and voluntary. There were also requirements for weight, blood pressure, pulse, and so on. ** 2. Digestive System ** 1. [Constitution: Composed of digestive tract and digestive gland.] 2. "Small intestine: It is the main place for digesting food and absorbing nutrients. There are digestive juices such as intestinal juice, intestinal juice, bile, and so on. Amylum is broken down into glucose here, protein is broken down into aa, and fat is broken down into fatty acid and glycerine." 3. The liver is the largest digestive gland in the human body. It secretes bile. Bile does not contain digestive hormones, but it has a significant increase in the digestive ability of fat. ** 3. Regarding the respiratory system ** 1. Lungs: The main organ of the respiratory system, the structure that completes the exchange of gases. 2. The throat is the passage through which gas and food pass, connecting the digestive system and respiratory system. 3. Tracheal: There is a C-shaped cartilaginous support on the wall, and phlegm can be formed in the trachea. ** 4. Blood composition and hormones ** 1. Pituitaries: can secrete growth hormones. If the secretion is too little, dwarfism will occur. If it is too much, giantism will occur. 2. Knowledge related to the role of various cell components in the blood could also be included in the handwritten report. ** 5. Cell aspect ** 1. Plant cells: The basic structure includes the cell wall (support, protection), cell membrane (control of the entry and exit of substances, protection), the plasma (liquid, mobile, there are vesicles inside, and many substances are dissolved in the vesicles), the nucleus (storage and transmission of genetic information), and the plastids (the site of photosynthesis). 2. [Animal cells: For example, oral cells have cell membranes (which control the entry and exit of substances), nuclei, and other structures.] He could also add some interesting little knowledge related to biology, stories of biologists, or explanations of some biological phenomena to make the handwritten report richer. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The teaching and research content of the junior high school biology department included many aspects: 1. ** Open class and class evaluation **: For example, teachers carry out open classes, such as Teacher Liu Honglei's open class "Nucleus-Division of labor and cooperation within the system", using a specific classroom model to let students actively participate. After that, the other teachers would evaluate the class and, on the basis of affirming the results, propose suggestions such as shortening the content and digging deeper into the knowledge to achieve common progress. 2. ** Discussion on the revision of teaching materials **: Reading the revised content of the high school biology version of the New People's Education to adapt the teaching to the development of the times. This practice is also useful for the teaching and research of junior high school biology. It can be used as an analogy to discuss the revision of junior high school biology teaching materials, so as to better grasp the teaching content. 3. ** Teaching method optimization **: - ** Carry out the "Four Cleanings" in teaching **: All biology teachers will seriously study the relevant guidelines and attach importance to the most important part of "Tangtang Qing". They will refer to the six teaching procedures and flexibly organize teaching according to the students 'foundation and teaching content. Students were required to master new knowledge in class, ensure practice time, complete homework in class, and mark it on the same day. At the same time, they could be divided into groups to let the team leader check the learning tasks. In order to improve the quality of teaching, we should focus on the "four optimization" in classroom teaching, namely, the optimization of teaching methods, classroom structure, teaching means and coaching methods. - ** Group lesson preparation **: This is an effective way to improve the quality of lesson preparation and classroom teaching efficiency. Teachers worked together to formulate teaching plans in a planned and organized manner, analyze the difficulties of teaching materials, determine teaching methods, and write lesson plans. In this process, teachers could deepen their understanding of the teaching materials, expand their teaching ideas, and improve their own quality. - ** Life-oriented teaching objectives **: When the teaching objectives are based on the students 'knowledge, ability, and emotional attitude, they can be introduced into social hot topics to achieve life-oriented. For example, using the topic of test-tube babies to discuss genetic knowledge, or telling the story of the cloned sheep, Dory. - ** Life-oriented teaching content **: Since junior high school students focus on thinking in images, they can use life-oriented explanations to help them understand abstract concepts or theories. For example, they could use the school level to simulate the structure of animals, or teach blood knowledge from the blood test report. - ** Diverse teaching methods **: - ** Scenario-based teaching **: For example, in the teaching of breathing, by introducing the topic of weight-loss methods around them, it will arouse the students 'interest and raise questions. It will make the students actively analyze the problems and connect knowledge with life. - Experiential Teaching: For example, an experiment to explore the effect of light on the lives of the rat women. Students were allowed to participate in the process of finding the rat women and understand their living environment. This could stimulate their interest in learning and cultivate their awareness of caring for life and maintaining ecological balance. - ** Practice-based teaching **: For example, when exploring the environmental conditions for seed sprouting, the students would be asked to do experiments at home after preparing for the lesson. Then, they would go to school to exchange the results, improve the students 'language expression and cooperation skills, and let the students experience the process of the production, formation, and development of biological knowledge. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Studying biology soon gives you knowledge about life forms and their functions. Writing a story related to it can help you communicate scientific ideas in a more engaging way. For example, you can make complex biological processes easier to understand for the general public through your story.
