亮点:在活动1“物体的沉浮”探究中,实验由学生操作,根据实验过程及实验现象独立完成学习单,从实践中发现实验规律,通过小组交流、讨论、概括出像木头、塑料等浮在水面上的材料漂浮能力强,像铁、橡皮泥等沉在水底的材料漂浮能力弱;不同的材料漂浮能力不同。在活动2“改变物体的沉浮状态”探究中,学生们通过交流和不断试验发现了改变物体的沉浮状态的方法:1.改变橡皮泥的形状;2.借助其他漂浮能力强的材料。本节课在学生中欢乐、好奇的探究实践中度过。
不足:时间设置不合理,第一项实验中学生操作占用时间过长,导致本次实验成果的汇报及学生展示学习卡的过程有些仓促,学生对于本节课知识的掌握程度展示不够。
改进:合理设置活动1的实验流程,多多通过实验操作锻炼学生的实验流畅度。

亮点:在活动1“物体的沉浮”探究中,实验由学生操作,根据实验过程及实验现象独立完成学习单,从实践中发现实验规律,通过小组交流、讨论、概括出像木头、塑料等浮在水面上的材料漂浮能力强,像铁、橡皮泥等沉在水底的材料漂浮能力弱;不同的材料漂浮能力不同。在活动2“改变物体的沉浮状态”探究中,学生们通过交流和不断试验发现了改变物体的沉浮状态的方法:1.改变橡皮泥的形状;2.借助其他漂浮能力强的材料。本节课在学生中欢乐、好奇的探究实践中度过。
不足:时间设置不合理,第一项实验中学生操作占用时间过长,导致本次实验成果的汇报及学生展示学习卡的过程有些仓促,学生对于本节课知识的掌握程度展示不够。
改进:合理设置活动1的实验流程,多多通过实验操作锻炼学生的实验流畅度。
