探究创新实验目的“说过一百遍,不如一实验。”可以说,做实验是学好中学化学的十分重要的条件。“氧气的溶解性”是氧气的重要物理性质之一,而在现行教材或教参书中,对“氧气不易溶解于水”却未曾设计过实验,只是以语言描述形式简单说一说。可是,这样简单的设计和语言,对于刚刚接触化学学科的中学生来说,未免有些费解和抽象。如果能用实验的方法使抽象的理论化为具体的实验情境,就能让我们感受到化学的可操作性、探究性,并能让我们从中领悟到化学理论的科学实质。
Exploring the Purpose of Innovative Experiment “Speaking a hundred times is not as good as experimenting.” It can be said that experimenting is a very important condition for learning chemistry in middle school. “Oxygen solubility ” is one of the important physical properties of oxygen, and in the current textbook or teaching reference book, “oxygen is not easy to dissolve in water” has not been designed experiment, just to describe the form of language simply One said. However, such a simple design and language can be a bit confusing and absurd for middle school students who have just come into contact with chemistry. If we can use experimental methods to abstract the theory into specific experimental situations, we can make us feel the operability of chemistry, exploration, and allow us to comprehend the scientific essence of chemical theory.
