大胆猜想、勇于探索和培养创新精神是当前课程改革的主体思想,以实验为主是物理教学的基础,在学习过程中,不仅要培养观察能力,分析问题和解决问题的能力,而且要注重动手能力和创新能力的培养,特别是一些创新的实验,它能引起学习物理的兴趣。就地取材来做一些实验,更能激发学习兴趣,启发创新意识,体验到物理就在我们身边。下面介绍一种热气球的制作方法。 Boldly guessing, brave to explore and cultivate innovative spirit is the main idea of ​​the current curriculum reform. Experiments are the basis of physics teaching. In the learning process, we must not only develop the ability to observe, analyze and solve problems, but also focus on hands-on. The cultivation of competence and innovation, especially some innovative experiments, can lead to interest in learning physics. Taking some experiments on the spot will stimulate students’ interest in learning, inspire new ideas, and experience physics beside us. Here’s how to make a hot air balloon.
