学习化学的一个重要途径是实验,通过实验以及对实验现象的观察、记录和分析等,可以发现和验证化学原理,学习科学探究的方法并获得化学知识。严谨的科学态度、合理的实验步骤和规范的操作方法是获得可靠实验结论的基本保证。新课程的培养目标是培养学生的合作精神和社会责任感,培养学生的民族自尊心、自信心和自豪感;引导学生学会学习,学会生存,能更好地适应现代生活。因此,初中化学实验显得尤为重要。 An important way to learn chemistry is to experiment. By experimenting and observing, recording and analyzing experimental phenomena, we can discover and verify the principles of chemistry, learn methods of scientific inquiry, and acquire chemical knowledge. Rigorous scientific attitude, reasonable experimental steps and normative methods of operation are the basic guarantees for obtaining reliable experimental conclusions. The goal of the new curriculum is to cultivate students ’cooperation spirit and sense of social responsibility, cultivate students’ national pride, self-confidence and pride; to guide students to learn to learn and to survive and to adapt to modern life better. Therefore, junior high school chemistry experiment is particularly important.
