Matters needing attention in experimental examination of physics and chemistry students

The matters needing attention in the experimental examination of physics and chemistry students are as follows:

① Every experimental exercise, we should think and summarize, find out our mistakes easily, and carry out targeted training to achieve the accuracy of the experiment.

② orderly operation, no hurry or rashness. After getting the exam questions, first recall what the teacher said when practicing these experiments. Generally, do big experiments first, and then do small experiments.

③ After entering the laboratory, first observe the placement position of pharmaceutical reagents and instruments on the experimental platform, and then begin to prepare for the experiment, so as to quickly find the drugs or instruments to be used during the experiment.

④ Pay attention to the process and present it perfectly. In the usual experimental practice, we must pay attention to the experimental details and process, and the standardized experimental operation is a necessary condition to get full marks.

Before the experiment, observe the name, range and division value of the equipment used to check whether the equipment is in good condition; In the process of experiment, we should strictly follow the steps and pay attention to every detail; After the experiment, the experimental equipment, all medicines and instruments should be arranged neatly, and the experimental platform should be cleaned. There are inevitably some mistakes in the examination process, so you can apply to the teacher for a fresh start.

Strategies for answering questions in the senior high school entrance examination

1. Order of doing the questions: generally, you should do it in the order of the questions. If you can't do it, you can put it aside and do other questions first. Don't spend too much time on one question, which will affect other questions; Specially remind students who are slow in doing problems to grasp the time and strive for a success rate; Students who are quick to do problems should pay attention to the quality of doing problems, be careful and not careless;

2. Problem-solving policy: consider various simple methods to solve problems, especially multiple-choice questions and fill-in-the-blank questions;

3. Answer requirements: In view of the high requirements of online marking, the whole layout of the answers should be designed before answering, and the words should be of moderate size. Don't write the answers outside the specified area. Otherwise, you can't scan the answers you wrote.

4. Mentality adjustment: Adjust your mental state. When solving exercises, don't be impetuous, and strive to get the level. Geek Math Help is here to teach you two mentalities when answering questions.

(1) If the test questions are difficult, follow the principle of "you are difficult for me, I am not afraid of difficulties", that is, if they are difficult, the math problems in the senior high school entrance examination are difficult for most candidates, so you can put them aside first and finish other simple questions before you break them, so don't doubt yourself, but believe that you have the ability to break them;

(2) If the test questions are easy, follow the principle of "You are easy for me, I am careless", that is, don't be caught in the pit by simple questions, the simpler the questions, the less careless they are.
