化学是一门以实验为基础的自然科学,对物质性质的知识来源于人们对物质进行研究的实验结论。实验结论为知识的形成与发展提供了源泉,知识为物质性质的研究提供了方法和指导作用。在此过程中,二者互相协作,共同发展。历年来高考化学实验试题都是全卷的难点,学生答题时往往手足无措,应接不暇,得分率也偏低。究其原因,一是由于学校办学条件的限制,尤其是偏远地区,学生连常见的实验仪
Chemistry is a natural science based on experimentation. The knowledge of the nature of matter comes from the experimental conclusions that people study of matter. The experimental conclusions provide a source for the formation and development of knowledge. Knowledge provides a method and guidance for the study of material properties. In this process, the two collaborate with each other and develop together. Chemical examination questions in college entrance examinations over the years are all difficult in the entire volume, and students are often at a loss when they are answering questions. The reason for this is that due to the limited conditions for running schools, especially in remote areas, students have common experimental instruments.
