Junior high school chemical heating reaction teaching plan design
The following is a teaching plan for a heating reaction of a chemical substance in junior high school: ** 1. Teaching objectives ** 1. ** Knowledge and Skill Target ** - Students can understand the significance of heating operations in chemistry experiments. - Master the correct use of common instruments (such as test tubes, beakers, etc.) when heating. - Understand the typical chemical reactions of different substances under heating conditions. 2. ** Course, Method, and Target ** - Through experimental demonstration and students 'experimental operation, students' observation ability and experimental operation ability were cultivated. - Guide the students to analyze the phenomenon in the heating reaction, and improve the students 'ability to summarize and think logically. 3. ** Emotions, attitudes, values, goals ** - Cultivate students 'rigorous scientific attitude and safety awareness. - To stimulate students 'interest in chemistry experiments. ** 2. Important and Difficult Points in Teaching ** 1. ** Teaching Focus ** - The correct use of heating equipment (alcohol lamp). - The operation points of different instruments under direct heating and indirect heating. - Experimental phenomena and chemical equations of typical heating reactions (such as the thermal decomposition of lithium hydrogen carbonates). 2. ** Teaching Difficulties ** - Understand the effect of heating on the rate and direction of chemical reactions. - Accurately determine the occurrence of chemical reactions based on experimental phenomena. ** 3. Teaching Method ** Teaching method, demonstration method, experimental inquiry method, and discussion method. ** 4. Teaching process ** #(1) Introduction (3 minutes) 1. The teacher asked,"Students, we have already come into contact with some chemical reactions in our previous chemistry studies. Can you recall if there are any reactions that require heating?" (Guide the students to recall the reactions such as the thermal decomposition of bronze) 2. The teacher played a video showing some phenomena related to heating in daily life, such as heating water to boil, cooking food, etc., and asked,"What special effect does heating have in chemistry experiments?" This led to the main topic of this lesson-the heating reaction of matter. #(2) Knowledge Explanation (10 minutes) 1. The meaning of heating - Explain the effect of heating on the properties of matter: - In terms of physical properties, it was mentioned that heating could cause a three-state change in a substance, such as heating ice to turn into water and then into steam; heating could also speed up the dissolving speed of a substance, such as dissolving cane sugar faster; most of the solid and liquid in water increased with the increase in temperature, and a few were the opposite (such as slaked lime). - In terms of chemical properties, some reactions that could not be spontaneously carried out at room temperature could be transformed into spontaneous reactions after heating, such as the decomposition of calcium dioxide into calcium dioxide and carbon dioxide at high temperature. Moreover, heating could accelerate the rate of chemical reactions. Many spontaneous chemical reactions accelerated after heating, and the energy released could maintain the reaction at a faster speed. 2. Heat instrument-spirit lamp - Demonstrate the spirit lamp and explain the structure of the spirit lamp, including the lamp cap, lamp body, and wick. - Details of the precautions for the use of the spirit lamp: - Before use, check whether the wick is flat and whether the amount of alcohol in the lamp is appropriate (not too little). If there is too little alcohol, add it with a funnel. - It emphasized that alcohol could not be added to a burning spirit lamp, and that one spirit lamp could not be used to connect to another burning spirit lamp. - When heating, the outer flame part of the flame should be used because the temperature of the outer flame is the highest. - When extinguishing, use the lamp cap to extinguish it, not blowing with your mouth. After extinguishing, use the lamp cap to prevent the alcohol from evaporating. #(3) Experimental demonstration (15 minutes) 1. direct heating experiment - Demonstrating how to heat a liquid using a test tube: - Take a clean test tube and add an appropriate amount of water (about 1/3 of the test tube volume). - Use a test tube clamp to hold the middle and upper part of the test tube, and tilt the test tube at about 45°. - Use the outer flame of the alcohol lamp to heat the bottom of the test tube to remind the students to observe the phenomenon when the water boils (bubbles, water surface fluctuations, etc.). - Demonstrate heating a solid with a dry test tube: - He took a small amount of copper sulfuric acid crystals and placed them at the bottom of a dry test tube. - Use the test tube clamp to fix the test tube, and the mouth of the test tube is slightly inclined downward (to prevent the condensed water from flowing back and causing the test tube to explode). - Heat it up with an alcohol lamp and let the students observe the change in color of the copper sulfuric acid crystal (from blue to white). 2. indirect heating experiment - Demonstrate heating the liquid in the beaker through the gauze: - Add more water to the beaker and insert the thermometer into the water. - He placed the gauze on the tripod and placed the beaker on the gauze. - Use an alcohol lamp to heat it up. Let the students observe the process of the water temperature rising. At the same time, emphasize that the role of the asbestos-mesh is to make the beaker heat evenly. - Simply mention the water bath heating (the silver mirror reaction can be used as an example to explain that the water bath heating can achieve uniform heating when the reaction temperature is less than 100°C, but it will not be demonstrated in detail). #(4) Student Experiment (15 minutes) 1. The students were divided into groups of three to four. 2. Each group of students was provided with experimental equipment and medicine, such as test tubes, alcohol lamps, matches, water, copper sulfuric acid crystals, etc. 3. Have the students perform the following experiments: - Heat a small amount of water with a test tube, observe and record the phenomenon. - Use a dry test tube to heat up a small amount of copper sulfuric acid crystals, observe and record the phenomenon. 4. The teacher patrolled and guided the students to correct their mistakes in time, such as heating with the inner flame, improper position of the test tube clamp, etc. #(5) Discussion and summary of experimental phenomena (10 minutes) 1. Let each group of students send a representative to report the experimental phenomenon. 2. Guide the students to analyze and summarize the experimental phenomena: - When it came to heating a liquid, boiling water was a physical change, and heating only changed the state of the water. - The color change of the copper sulfuric acid crystal was due to a chemical change. The reaction equation was: CuSO4 + 5H2O. 3. He emphasized the key points of the heating operation again, including the correct use of the instrument and the safety precautions for heating. #(6) Class summary (5 minutes) 1. Review the main content of this lesson with the students: - The significance of heating operations in chemical experiments included the effects on the physical and chemical properties of substances. - The correct way to use an alcohol lamp. - The experimental operation points of direct heating and indirect heating. - Phenomena and related chemical reactions observed through experiments. 2. He emphasized the importance of heating operation in future chemistry studies and experiments. #(7) Homework 1. written assignment - Ask the students to complete the exercise questions on the heating reaction of substances in the textbook, such as writing the chemical equation for heating the hydrogen carbonates. 2. Extension homework - Ask the students to look up the materials and find out what other substances will have interesting reactions when heated.

Determination of teaching objectives ** 1. ** Knowledge and Skill Target ** - For example, the content of "The structure of flowers" was to let students identify the structure of various parts of flowers and learn the basic methods of dissecting flowers."The formation of fruits and seeds" was to let students understand the structural changes in the process of fruit and seed formation."Blood vessels" was to let students briefly describe the structure and functional characteristics of arteries, veins, and capillaries and distinguish the three types of blood vessels. 2. ** Course, Method, and Target ** - In <<The structure of flowers>>, the students 'observation ability and hands-on operation ability were trained through the observation and dissection of peach blossoms. In <<Blood vessels>>, the students' observation ability and induction ability were improved through model observation. 3. ** Emotions, attitudes, values, goals ** - For example, through the study of the structure and function of various parts of flowers, the structure of flowers gradually formed the biological point of view of "the unity of biological structure and function", enhancing the awareness of caring for vegetation; the concept of the unity of structure and function was formed in the blood vessels. ** 2. Determination of teaching difficulties ** 1. ** Main point ** - The structure, dissection, and observation of flowers in <<The structure of flowers>> were the main points; the formation of fruits and seeds in <<The formation of fruits and seeds>> were the main points; and the structure and function of the three blood vessels in <<Blood Vessel>> were the main points. 2. ** Difficulty ** - It was difficult for students to master the dissection and observation methods of flowers in the book "The structure of flowers"; it was difficult for students to understand the corresponding parts of flowers that developed into fruits and seeds in the book "The formation of fruits and seeds"; it was difficult to understand the relationship between the structure and function of blood vessels in the book "Blood Vessel". ** 3. Design of the teaching process ** 1. ** Introduction to a new lesson ** - In "The structure of flowers," a variety of videos of flowers blooming were presented on a variety of media to draw out the topic."Blood vessels" guided students to tie bandages on each other's wrists and observe the changes in the back of their hands to draw out the knowledge related to "blue veins"(blood vessels). 2. ** Exploring new knowledge (new lesson)** - In "The structure of flowers", the students were asked to tell the structure of the flower by intuition. Then, the teacher would guide them to observe the structure of the flower in a certain order, recognize the structure of the flower stalk, the flower holder, and so on. They would also carry out the dissection experiment of the flower. In "The formation of fruits and seeds", the knowledge points were drawn out by doing questions, and then the changes of the structure of each part of the flower during the formation of fruits and seeds were explained in detail. In "Blood Vessel", the students were asked to observe the blood vessels and blood flow in the caudal fin of small fish, and then the types and functions of the blood vessels were taught. 3. ** Consolidating and improving ** - For example, in the book "The Structure of Flowers", students were instructed to draw the structure of the dissected flower and label the name of the structure. 4. ** Class summary ** - Guide the students to share their gains from this lesson and clarify the key content. 5. ** Homework arrangement ** - For example,"The Structure of Flowers" allowed students to introduce the knowledge gained in class to their family and friends after class. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
