学习每一学科都要有适合自己的学习方法,学习化学也不例外掌握好的学习方法就有可能达到事半功倍的效果,不合适自己的方法可能就要事倍功半了。进入初三年级,我们会接触一门新的学科即化学,它是以实验为基础,研究物质的组成、结构、性质及其变化规律的自然科学在学习化学知识中,许多知识如化学概念、基本原理、元素化合物性质等,都是通过化学实验而获得的。因此,在化学学习中必 Learning each discipline should have their own learning methods, learning chemistry is no exception to master a good learning method may be able to achieve a multiplier effect, inappropriate methods may be less effective. Entering the third grade, we will come into contact with a new discipline, chemistry, which is a science based on experiments that studies the composition, structure, nature and changing laws of matter. In studying chemical knowledge, many knowledge such as chemical concepts, The basic principle, the nature of the elemental compounds, are obtained through chemical experiments. Therefore, in chemistry learning must
