Unit7 How do things change ？Explore（课件+素材）-2025-2026学年沪教版英语四年级下册

该小学英语课件围绕“物质变化”主题，核心知识点包括食物制作相关词汇（如cream, sugar）、建议句型（Shall we..., Let's...）及科学探究过程（制作冰淇淋）。课堂导入通过“点击小鸟读单词”游戏复习solid等旧词，结合“冰淇淋融化”现象观察，搭建从旧知到新知的学习支架，引导学生自然进入主题。 其亮点在于融合语言学习与科学探究，通过真实情境任务提升语言能力和思维品质。例如制作冰淇淋对话中运用Shall we...句型，结合cause and effect匹配活动培养逻辑思维，小组朗读、实践制作（如鸡汤、果汁）等多样化互动增强学习参与。这既帮助学生提升语言运用和问题解决能力，也为教师提供丰富情境教学素材，提高课堂效率。
