The following is a teaching plan for a parallel circuit for measuring current in junior high school physics: ##1. Teaching objectives 1. Knowledge and Skill Target - Students are able to use ammeters to measure the current in parallel circuits. - Understand the law of current flow in parallel circuits. 2. process, method, goal - Through experimental operation, students 'hands-on ability and experimental inquiry ability were cultivated. - During the experiment, the students 'ability to collect, analyze, and process data was improved. 3. Emotions, attitudes, values, goals - Cultivate students 'rigorous scientific attitude and teamwork spirit. ##2. Difficulties in Teaching 1. ** Main point ** - Master the current law of the parallel circuit. - Correct use of ammeter to measure the current of each branch and trunk of the parallel circuit. 2. ** Difficulty ** - The connection of the experimental circuit was to ensure that the circuit connection was correct and the ammeter range was selected appropriately. - Through the analysis and summary of the experimental data, the current law of the parallel circuit was obtained. ##3. Teaching Method Teaching method, experimental inquiry method, group cooperation method ##4. Teaching process 1. ** Course import (3 minutes)** - By reviewing the current law of the series circuit, it leads to the exploration of the current law of the parallel circuit to stimulate the students 'interest and curiosity. 2. ** Knowledge explanation (7 minutes)** - It briefly introduced the usage of the ammeter, including the range selection, the connection of the positive and negative terminal, and the reading method. - He explained the structural characteristics of the parallel circuit to pave the way for the subsequent experimental exploration. 3. ** Experimental Exploration (25 minutes)** - Group: Divide the students into groups of 4 - 5 people. - Experimental steps: - Each group connected a parallel circuit according to the circuit diagram. The circuit included a power supply, a switch, a small light bulb (two different specifications), and an ammeter. - First, connect the ammeter in series in the main road, close the switch, and read and record the number of ammeters. - Then, the ammeters were connected in series in the two branches, and the switch was closed. The ammeters of each branch were read and recorded. - Change the small light bulbs of different specifications and repeat the above experimental steps. - During the experiment, the teacher patrolled each group to find and solve the problems encountered by the students in time, such as circuit connection failure, improper selection of ammeter range, etc. 4. ** Data analysis and pattern summary (10 minutes)** - Each group analyzed the experimental data and compared the relationship between the main current and the current of each branch. - The students were guided to find out the current law of the parallel circuit: the main current in the parallel circuit was equal to the sum of the current of each branch. - Students are encouraged to think about the possible errors in the experiment and the reasons for them, such as ammeter reading errors, poor circuit connections, etc. 5. ** Class summary (3 minutes)** - Review the main content of this lesson with the students, including the use of ammeters, the current law of parallel circuits, and the process and methods of experimental exploration. - He emphasized the issues that needed to be paid attention to in the experiment, such as circuit safety, data accuracy, etc. 6. ** Homework (2 minutes)** - Arrange homework after class, such as asking students to design an experimental plan to measure the current of a more complicated parallel circuit according to the experimental exploration process of this class. ##5. Reflection on Teaching 1. ** Success ** - Through experimental exploration, students could experience the exploration process of the current law of the parallel circuit, which would help to improve their practical ability and scientific exploration ability. - In the process of group cooperation, the students 'teamwork spirit was cultivated. Students communicated and cooperated with each other to complete the experimental tasks together. - It focused on guiding students to analyze and process experimental data, cultivating students 'scientific thinking ability, allowing students to discover laws from data, and improving students' understanding and mastery of physics knowledge. 2. ** Inadequacies ** - During the experiment, some students were not familiar with the use of the ammeter, and there were errors in the range selection and inaccurate readings. In the future, special training on the use of the ammeter should be strengthened. - Due to the limited time of the experiment, some groups were hasty in the experiment process and did not fully explore the commonality of the current law of the parallel circuit under different circumstances. In the future teaching, the experiment time could be extended appropriately or the preparation could be arranged in advance. - In the class summary section, students could participate more in the summary instead of being led by the teacher. This would better test the students 'mastery of the knowledge of the class. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Different regions and different positions would have different scores. For example, in 2022, the lowest score for public institutions in Guangshan County was 33 points, and the highest score for written examination was 91.8 points. If a unit directly under Gongyi City wanted to successfully enter the interview, it was better to set the written examination target score at 70 points. Therefore, it was difficult to determine the exact score. It would be affected by many factors such as the region, the degree of competition for the position, and the number of applicants. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

If there was no reaction from Kovalz when he inserted the key and ignited the fire, it could be because of the following reasons: 1. ** Due to human manipulation ** - ** battery power problem **: It may be that the battery is exhausted, such as the long-term headlights are not turned off, resulting in a loss of battery power or the end of the battery life (usually it is recommended to replace the battery in 2 years). It may also be that the installation of Xenon headlights, high-power audio, and other electrical faults in the vehicle cause the battery to lose power. You can check if the car is out of battery by pressing the horn. - [** Missing fuel in the fuel tank **: When the fuel gauge shows that it is below the red line, it will naturally not be able to ignite.] - ** Wrong gear setting **: When an automatic transmission vehicle starts, the gear must be placed above P or N. If it is in R or D, it will not be able to ignite. Some manual transmission vehicles will also not be able to ignite if they do not step on the clutch. 2. ** Due to vehicle component malfunction ** - ** Failure of the motor **: The motor's brushes are seriously worn, the internal circuit is short-circuited, and the motor is stuck. All these phenomena will cause the motor to start without any response. The motor needs to be thoroughly and carefully checked and repaired. - ** Oil pump, fuel injection valve malfunction or sensor abnormality **: These situations are more complicated and require professional personnel to handle. - ** Spark plug carbon deposit **: Spark plug carbon deposit may affect ignition. - ** Failure of the ignition system **: For example, there is a problem with the circuit from the ignition switch to the starter. The key is the electromagnetic switch of the starter, followed by the ignition switch. When starting, you can observe whether the brightness of the vehicle instrument lamp changes. If it is dark, it may be that the battery is out of power. If it does not change, it may be that the starter is broken or the ignition switch under the key door is broken. - ** Oil quality problem **: Poor quality oil with impurities such as water and mud in the fuel tank may cause the vehicle to be unable to ignite. It is recommended to refuel at a regular gas station. When going out, you can use gauze to wrap the muzzle of the gas gun to filter the impurities. - ** No Antifreeze **: Some car owners add water or low-quality Antifreeze to the car. In the extremely cold winter, it may cause the entire waterway to freeze and the engine to crack. This will make the car's water pump unable to operate, unable to ignite, and damage other parts of the engine. - ** Too much carbon on the vehicle **: Too much carbon on the vehicle will cause the vehicle to be unable to ignite. You can often run at high speed to reduce the carbon deposit. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
