U6 Looking into science Lesson 5-【绿卡初中创新题】2026-2027学年九年级上册英语习题课件(冀教版·新教材)

该初中英语课件围绕Unit 6 Looking into science的Lesson 5“Keep the candle burning!”展开，核心知识点涵盖科学实验（如Coanda效应）的步骤、现象解释及相关英语阅读与表达。课堂导入通过呈现实验所需材料（蜡烛、容器等）和操作步骤，引导学生从实践理解过渡到语言学习，构建“实验操作-现象分析-语言应用”的学习支架。 其亮点在于以科学实验和生活情境（如打水漂对话）为载体，融合语言能力（阅读理解题、补全对话）与思维品质（实验现象推断、问题解决），采用“情境化、任务型”的学科特色教学方法。通过具体实例如实验步骤描述、对话建议交流，帮助学生提升语言应用与逻辑思维，同时为教师提供生动教学素材，有效增强课堂互动性。
