【摘要】 以“隐形墨水的制作”为主题，从生活中神奇的现象出发，开展初中化学“酸与碱”专题复习的教学。通过学生学习原理、亲自动手制作、展示和应用“隐形墨水”,更好地促进学生掌握溶液的酸碱性及遇指示剂的变色情况，理解酸与碱的概念、化学性质以及发生的化学反应。在多个任务的驱动下，学生的动手能力和解决问题的能力不断增强，科学探究意识和学科核心素养不断提高，让学生能切身地感受到化学与生活的紧密联系以及化学的魅力。更多还原

【Abstract】 Taking “the production of invisible ink” as the theme and starting from the magical phenomena in life, the special review teaching of “acid and base” in junior high school chemistry is carried out. Through students’ personal understanding of the principle, hands-on production, display and application of “invisible ink”, students can better master the acidity and alkalinity of the solution and the discoloration of the indicator, and understand the concept, chemical properties and chemical reactions of acid and alkali. Driven by multiple tasks, students’ practical ability and problem-solving ability are continuously enhanced, their awareness of scientific inquiry and discipline core literacy are continuously improved, and they can personally feel the close relationship between chemistry and life and the charm of chemistry.更多还原
