化学是一门研究物质结构、组成、性质以及变化规律的学科。生活中处处有化学,世界专利发明中,有20%与化学有关;发达国家从事研究与开发的科技人员中,化学与化工专家占一半左右;在我们的高中生活中,化学也占据着相当重要的地位。化学推论的起点都是实验,要设计好开放性实验的每一个环节,注重实验过程的创新,注重实验细节,提高创新意识和能力。
Chemistry is a discipline that studies the structure, composition, nature, and variation of matter. Chemistry is everywhere in life. Of the world’s patented inventions, 20% are related to chemistry. Among the scientists and technicians engaged in research and development in developed countries, about half are chemical and chemical experts. In our high school life, chemistry also plays a very important role Position. The starting point of chemical inference are all experiments, we should design every aspect of the open experiment, pay attention to the innovation of the experimental process, pay attention to the experimental details, improve the awareness and ability of innovation.
