初中化学是以实验为基础的学科,该学科起源于实验又依赖于实验。因此,初学者学习化学时不能照搬过去学习其他学科的经验和方法,要重视实验,学会从实验中获取新知,首先就要学会观察实验,这是学好化学的基础,是培养和提高观察能力和实验能力的关键。一、熟悉观察的顺序化学离不开实验。无论是教师的演示实验还是学生的动手操作,只有从实验现象入手,认真观察,仔细分析,才能探寻化学真知。而观察必须遵循一定顺序,不能随心所 Junior high school chemistry is based on the experimental discipline, the discipline originated in the experiment and relies on the experiment. Therefore, beginners learn chemistry can not copy the past to learn other disciplines of experience and methods, to attach importance to experiment, learn to obtain new knowledge from the experiment, we must first learn to observe the experiment, which is to learn chemistry, is to develop and improve the ability of observation and The key to experimental ability. First, familiar with the order of observation Chemistry can not be separated from the experiment. Whether the teacher’s demonstration experiment or the student’s hands-on operation, only from the experimental phenomena, careful observation, careful analysis, to explore the chemical truth. Observation must follow a certain order, can not be arbitrary
