How to learn middle school chemistry well? Did you get these methods?

Junior high school is the basic stage of chemistry learning. The high school chemistry entrance examination is a comprehensive investigation of junior high school chemistry learning. Everyone wants to lay a solid foundation and achieve excellent results. So how to learn middle school chemistry well? Here are a few things to share with you:

First of all, preview before class, take notes in class, and preview the text in order to listen to the class more effectively. Preview in advance, read carefully, and think about the content of the text; students will find out what they don’t understand, where there are problems, and where they need to be raised by the teacher; when the teacher talks about these places in class, they should pay attention to them and take notes. Junior high school has a lot of chemistry content and scattered knowledge points. It is necessary to preview before class. Take notes on the key and difficult points in class to prepare for the key review in the future.

1. More review, more practice, more memorization. Reviewing in time after class and doing homework seriously are an important part of learning chemistry. The review can use after-school review, unit review, chapter review, comprehensive review and so on. Doing exercises and chapter exercises in time after class, memorizing in the exercises, comparing and correcting errors, is also a good way to learn and memorize. Chemical terms and definitions should be carefully distinguished. The chemical equation and common chemical reactions should be kept in mind. Attention should be paid to the conditions of chemical reactions (heating, light, catalyst) and arrows (reversible, irreversible). The formulas in chemistry must be understood, memorized, integrated, and used flexibly like mathematical formulas. Chemistry is the liberal arts of science, and many knowledge points need to be memorized. Sort out some necessary content and use spare time to read and remember. Only by reviewing more, practicing more, and remembering more can we lay a good foundation.

Third, attach importance to experiments and cultivate interest. Chemistry is an experiment-based discipline. Observe the teacher's demonstration experiment carefully and do a good job in each group experiment. The instruments, drugs, and instruments used in the experiment, as well as the principles, procedures, phenomena and precautions of the experiment, must be clearly understood and memorized. The content of middle school chemistry is closely related to life and production. This requires that while studying chemistry, we should try our best to get in touch with the reality of production and life, discover chemistry from the lives around us, and appreciate chemistry, so that we can be more interested in learning, want to learn more, and love to learn more.
