物理是一门以观察、实验为基础的科学，许多的物理知识都是通过观察和实验认真加以总结和思索得来的．引入概念、推出规律、检验猜想和发展新知，都离不开实验这个重要途径．因此，学习物理，我们不仅要认真观察老师做的实验，还要自己动手努力做好实验．下面就和同学们来谈谈 Physics is a science based on observation and experiments. Many physical knowledge are carefully summarized and thought through observation and experimentation. The introduction of concepts, the introduction of laws, testing conjectures and the development of new knowledge, are all inseparable from this important experimental approach. Therefore, to study physics, we must not only carefully observe the experiments made by teachers, but also try our best to do experiments. Let’s talk to the classmates below
