1、尚德小学四年级下册科学实验教学计划以培养小学生科学素养为宗旨，积极倡导让学生亲身经历以探究为主的学习活动，培养他们的好奇心和探究欲，发展他们对科学本质的理解，使他们学会探究解决问题的策略，为他们终身的学习和生活打好基础。一、学情分析:通过一年多的科学学习，同学们对科学都很感兴趣，但仍存在很多问题（1）由于教学条件的有限，学生缺乏独立实验的能力，几乎没有科学实验、科学探索的概念，并且差生面较广。（2）家庭及周围能配合的力量没有，学生要准备的实验材料没有。（3）用于提供给学生探索与观察的环境与时机太少。孩子们活动范围较少，接触面较窄，再加上要忙于作业，并且学生家长不重视，更少有家长配合与帮助。二、

2、教材分析：本册内容由“电”、“新的生命”、“食物”和“岩石和矿物”四个单元组成。“电”单元是从“什么是电”开始的。学生对静电有比较丰富的生活体验，让他们适当地了解一点有关电荷的知识，可以使后续课中电流、电路的学习更有基础。这一单元将通过与电相关内容的实验、交流、预测、检验、测量和推理、解释等活动，使学生形成关于电的初步概念，同时获得一些基本实验操作技能。“新的生命”单元是从“观察油菜花”引入的。由植物的花、果实和种子的系列观察活动，过渡到动物的卵、繁殖的观察和研究，从而使学生获得植物和动物如何繁殖新生命的认识，并形成关于生命的一系列发展性概念。教科书中的观察实验，特别是一些探究性的实验，都是在

3、支撑有关生命概念的建立，并在此过程中使学生获得对生命的理解。“食物”单元通过对一天中所吃食物的回忆和分类，引起学生对饮食的关注，发现自己在饮食中的不良习惯，并在以后的生活中，能科学、合理、均衡地饮食。食物的变化和获取食物信息方法的研究也是在帮助学生进一步认识事物的特征及其变化规律。“岩石和矿物”单元是学生初次对构成地球固体物质的探究。通过对岩石、矿物的观察、分类和描述，使学生形成关于地球物质的一般性概念，并对保护、开发和利用地球资源的重要意义有进一步的了解。本学年是培养学生科学素养的至关重要的时期。教学中要因势利导，积极引导学生在学习中逐渐养成尊重客观事实、注重证据、大胆质疑的科学品质和思维方

4、式，提高他们的生活质量和学习质量。三、实验目的：1、培养学生学习科学的乐趣。2、让学生获得简单的科学知识。3、培养学生包括观察、发现和记录的能力。四、实验措施：1、课前教师要备教材、备学生、备教法、备实验过程。2、课上培养学生观察、发现和记录的能力。3、培养学生的动手活动能力。4、养成搜集资料的习惯。5、在教学实验中可以从中华人民共和国可再生能源法及中华人民共和国食品安全法等向学生渗透相关法律知识。五、实验安排：周次 实 验 内 容演示 分组 实 验 器 材1 体验静电现象一把塑料梳子、碎纸屑、几个气球、1 不一样的电荷绑气球的细线、挂气球的支架、静电现象的相关图片或幻灯片。1 点亮小电泡绑气
