广州市举办了多年的中学生晶体制作实验比赛,学生对晶体制作的兴趣延伸到对化学学科的兴趣,通过实验探究,学生能初步运用所学知识解决生活中与化学有关的问题,真正做到学有所用。对于初中学生而言,这样做有利于培养学生学习化学的兴趣和探究的欲望,但是由于知识有限,且在大晶体制作实验进行时学生还没有接触溶液的有关知识,制作起来难度相对会大很多。对高中学生而言,探究的广度和深度不同,要求也就不同。经过大量的实验探究,笔者对溶 Guangzhou City held many years of experimental production of high school students crystal experiment, students interested in the production of crystal extended to the interest of chemistry, through experimental exploration, students can use their knowledge to solve the chemical-related issues in life, truly learn Useful. For junior high school students, doing so will help to develop students’ interest in chemistry and inquiry, but due to limited knowledge and the fact that students have no contact with solution during large crystal making experiments, it is more difficult to make them . For high school students, the breadth and depth of inquiry are different and the requirements are different. After a large number of experiments to explore, I dissolved
