The Method of Extracting Carotenin from High School Experimental Creatures
In the high school biology experiment, the method to extract the beta beta carotinoid was as follows: First, the carrots were crushed and dried. Then, the extraction method was used to select a suitable organic solution, such as the mineral ether (because of its high boiling point, it can fully dissolve the beta beta During the extraction process, heating with an open flame should be avoided and a water bath should be used. After the extraction, it was filtered to remove the solid impurities, and then the filtered liquid was concentrated to finally obtain the beta-Carotenin. The efficiency of the extraction mainly depended on the nature and amount of the extracting agent used. At the same time, it was also affected by the size of the raw material particles, the degree of tightness, the water content, the temperature and time of extraction, and other conditions. Generally speaking, the extraction effect would be good if the raw material particles were small, the extraction temperature was high, and the extraction time was long.

The Experimental Method of Fictional Esthetics
The research methods of experimental aesthetics were worth learning and developing, but some problems had to be avoided. Don't be too obsessed with it and regard it as the only and complete way of aesthetic research, and don't rigidly turn the experimental results of forms and methods into an unchanging formula, lest artistic creation and appreciation become a formalized label recognition process. In terms of novel aesthetics, for example, in conceiving narrative plots to reflect the artistic aspects of life, the way British aestheticians turned life into art through various external modifications and internal cultivation could be used as a reference. For example, Wilde tried to show the process of a person turning life into art in The Picture of Dorian Gray. The author described purely fictional or even absurd plots in a realistic background, making the novel have a strong symbolic meaning to express aesthetic views. This could also be seen as a way to explore the aesthetics of novels. In addition, from the perspective of analytical aesthetics, the theoretical analysis of contemporary aesthetic problems such as "artistic convention theory","intention criticism","artistic symbol","metaphor","performance", and "evaluation of art" also has certain reference significance for the aesthetics of novels, which is helpful to understand the aesthetic elements in novels from different aspects. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Tuition fees for the National Preceptor's Experimental High School

The Writing Method of High School Biology Experiment
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>

Reaction Time Method and Commonly Used Experimental Instruments
The reaction time method was mainly divided into two parts: the difference method and the addition factor method. Subtraction was a method of decomposing the reaction time into its components by the reduction method, and then used to analyze the information processing process.(One of them contains a specific mental process that the other does not.) The other aspects of the two tasks are the same, and the difference in reaction time is the time required for this processing process. It has applications in the study of memory information coding methods, mental rotation time research, and many other aspects. The idea of substitution is also applied to the reduction of ERPs and the reduction of brain activation areas in fMRI. The additive-factor method believes that the time required to complete a task is the sum of the time required for a series of information processing stages. If the effects of two factors restrict each other, they act on the same information processing stage. If the effects are independent (can be added), they act on different processing stages. There were many commonly used instruments in chemical experiments, such as directly heated test tubes, evaporating dishes, burning spoons, crucibles; beakers, conical flasks, and flasks that were indirectly heated with clay nets; medicine spoons for taking powder solid, tweezers for lump solid, rubber head dropper for a small amount of liquid, measuring cylinder for a certain amount of liquid; wide mouth bottles for storing solid, thin mouth bottles and drop bottles for liquid, gas collection bottles; measuring tray scales and measuring cylinders; funnels for adding liquid, long-necked funnels, separating funnels, etc. There was no mention of specific commonly used instruments in psychological experiments, but related instruments such as stimulus-presenting equipment may be used when studying responses (the specific names of the instruments were not explicitly mentioned). In experiments of different disciplines, the reaction time method had different connections with experimental instruments. In chemistry, experimental instruments were used for chemical reactions, while in psychology, if one were to perform experiments related to the reaction time method, they needed corresponding equipment to display stimulation and other operations to measure the reaction time. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
