Junior high school entrance examination biology experiment, the cells
In the middle school biology experiment, there was an experiment that involved observing human oral cells. The main experimental steps were as follows: 1. Wipe: Wipe the glass slide and cover glass clean with clean gauze. 2. Drip: Drip a drop of 0.9% physiological salt solution in the center of the slide with a dropper to maintain the normal shape of the cells. 3. Scratch: Use a sterilized cotton swab to gently scrape the inner wall of your mouth (the purpose of gargling is to remove impurities in the mouth). 4. Painting: Put the end of the cotton swab with debris on the glass slide and smear it in the drop of normal salt solution. 5. Cover: Use tweezers to pick up the cover glass, so that one side of it first touches the water drop on the slide, and then slowly lay it flat. 6. Staining: Drop a drop of diluted solution of iodination on one side of the cover glass, and use blotting paper to suck it on the other side of the cover glass, so that the dye solution can permeate the entire specimen. In addition, when making temporary slide specimens of human oral tissues, there were some precautions, such as tilting the toothpicks and not scraping at the same place to avoid scratching the inner wall of the oral cavity; throwing the used toothpicks and blotting paper into the trash can, and wiping the experiment table clean. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to review before the Sichuan biology high school entrance examination
Sichuan biology high school entrance examination review can be carried out according to the following strategies: * * I. Chapter-by-chapter review (Foundation Stage)** 1. * * Returning to teaching materials, building a framework ** - Using the content of the textbook as the foundation, he would construct a knowledge framework according to the chapters of the textbook, such as forming a mind map. This helped to systematically sort out the various knowledge points because no matter how the format of the test questions changed, the knowledge points would not change. A solid grasp of the textbook content was the key to obtaining basic points. 2. * * Consolidating basic concepts and techniques ** - Grasp the most basic biological concepts, formulas, and some basic calculation skills (if involved) and solution ideas. For example, he had to have a clear understanding of the concepts and calculations related to the laws of genetics in living creatures. 3. * * Practice Set ** - After familiarizing himself with the content of the textbook, he did some basic exercises. Through practice, he could further consolidate his basic knowledge, improve his ability to understand and apply basic knowledge, and at the same time, cultivate his ability to think and solve problems. * * 2. Build a Knowledge System (System Integration Stage)** 1. * * Comprehension of Knowledge ** - After completing the summary of the knowledge in each chapter, he would integrate the knowledge in each chapter to form a complete comprehensive knowledge system and deeply understand the internal connections of each knowledge point. For example, in biology, there were logical connections between topics such as "scientific inquiry, the structural level of organisms, and organisms and the environment." 2. * * Comprehensive Practice ** - Choose a comprehensive or middle school entrance exam simulation test questions for the practice. In the process of practice, enhance the practical ability and flexible application of knowledge, improve the overall grasp of the textbook knowledge and systematic. At the same time, he would deepen his understanding of the internal relationship between the knowledge points. When selecting the test preparation materials, one had to pay attention to factors such as the publishing house (the quality of the supplementary materials of the famous publishing house was guaranteed), the old and new materials (the real test questions and simulation questions in recent years had higher reference value), and so on. * * 3. Special review (deepening and expanding stage)** 1. * * Sorting out the question types and modules ** - The revision content of the biology high school entrance examination could be summarized as "scientific inquiry, the structural level of organisms, organisms and the environment, green plants in the biosphere, humans in the biosphere, the movement and behavior of animals, the reproduction, development, and inheritance of organisms, the variety of organisms, biotechnology, and healthy living." The examinees had to sort out the biology questions in the middle school entrance examination in recent years and grasp the characteristics of the questions. 2. * * Connecting life and knowledge application ** - Extending the textbook knowledge into life, he could freely use the knowledge he had learned to solve problems. For example, when learning about biology and the environment, he could relate it to ecological phenomena in life. 3. * * Real and mock exercises ** - He had to do more mock questions and real exam questions from various schools in the past two years to familiarize himself with the question setter's thoughts and scoring points, and to regulate the answer mode. In actual combat, he would strengthen his ability to use subject knowledge to analyze test questions, improve the speed and accuracy of solving questions, and especially clearly answer comprehensive questions with high difficulty. In addition, due to the changes in the 2024 biology curriculum standard, one could also choose to practice according to the real test papers published by the new test sites. This information sorted out and summarized the test sites changed by the new curriculum standard, including the frequency of inspection and key points of the test sites, which was convenient for review. During the practice process, if there was a knowledge manual (such as a knowledge manual that came with some practice materials), the knowledge points that were not firmly grasped during the practice process could be read and consolidated in time. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
