一、充分利用化学实验的魅力,培养学生的观察和动手能力化学是一门以实验为基础的学科,一切的理论都离不开实验的证明。另外化学实验分为好多种,如微型实验,探究实验,开放实验等等。其中微型实验可以让学生充分利用身边的物品进行,教师也可以根据身边的事物组织实验,在一定程度上不仅节约了时间、节约了药品;还减少了污染。例如探究酸碱盐的性质可以用药品铝箔代替试管,探究氯气的性质时可以利用学校花园中
First, make full use of the charm of chemical experiments to develop students’ ability to observe and practice Chemistry is an experimental discipline-based disciplines, all of which can not be separated from the experimental proof. In addition the chemical experiment is divided into many kinds, such as micro-experiment, exploration experiment, open experiment and so on. Micro-experiment which allows students to take full advantage of the items around them, teachers can organize experiments based on things around, to some extent, not only saves time, saving drugs; also reduces pollution. For example, to explore the nature of acid-base aluminum foil can be used instead of test tubes to explore the nature of chlorine can be used in the school garden
