爱因斯坦说过:提出一个问题往往比解决一个问题更重要。因为解决问题也许仅是一个数学上或实验上的技能而已,而提出新的问题,不仅需要有创造性的想像力,而且标志着科学的真正进步。因此,在科学探究实验教学中,教师要努力创设情境,大胆放手让学生动手操作,引导学生自己发现问题,提出问题,研究问题,在探究中发现规律,得出科学结论。然而,在科学技术越来越发达的今天,产生了越来越多的废物和垃圾,只要教师细心观察,注意归类,就能发现许多 Einstein said: It is often more important to ask one question than to solve one. Because solving problems may be just a mathematical or experimental skill, asking new questions requires not only creative imagination but also real progress in science. Therefore, in the teaching of scientific inquiry experiment, teachers should strive to create the situation, boldly let the students hands-on operation, guide the students to discover the problems by themselves, ask the questions and study the problems, discover the laws in the inquiry, and draw the scientific conclusions. However, with the development of science and technology, more and more wastes and rubbish are produced. As long as the teachers carefully observe and pay attention to the classification, many can be found
