一、教学程序设计及意图《水的浮力》一课,从能力培养来看,属于“实验能力和归纳概括能力”的系列。要让学生通过活动操作、观察、讨论、数据的统计与分析知道什么叫做水的浮力,各种物体在水中都受到水的浮力以及浮沉规律在生活、生产中的应用。引导学生通过实验引出研究问题, First, the teaching program design and intent “buoyancy of water,” a lesson, from the ability to cultivate point of view, belong to the “experimental abilities and generalization ability” series. Let students know what is called the buoyancy of water through the operation, observation, discussion, statistics and analysis of the data. All kinds of objects in the water are subjected to the buoyancy of water and the law of floating and sinking in the life and production. Guide students to lead research questions through experiments,
