Unit 5 Lesson 26（课件）-2025-2026学年冀教版（2012）英语九年级全一册

该初中英语课件围绕“蜡烛燃烧实验”展开，核心知识点包括实验步骤的英语表达及"use up""be made up of"等短语。课堂导入通过复习旧知“气压实验”、Free Talk提问“罐子倒扣燃烧蜡烛的现象”搭建支架，衔接前后知识脉络。 其亮点在于融合科学探究与语言学习，通过实验步骤排序、结果分析等任务培养学生逻辑思维（思维品质），结合视频辅助和分层练习提升语言运用能力（语言能力）与学习效率（学习能力）。如Reading tasks引导学生按逻辑排序实验步骤，Language points结合实验现象解析短语，助力学生理解科学与英语的联系，也为教师提供完整教学链，便于高效教学。
