1.让学生乐于探索。在科学活动中,材料是物质环境的一部分,是学生探索的主要对象,为了激发学生的探索欲望,我们在提供材料时注意:首先,提供便于学生操作与观察的材料;其次,提供蕴含教育价值的材料。如:在“沉与浮”的活动中,学生猜想轻的物体会浮,重的会沉。于是,我们提供了水果、硬币、萝卜、回形针、大木块等材料,最后的实验结果与他们的设想大相径庭。通过反复操作,他们逐渐认识到“物体的轻重不能决定
Let students be willing to explore. In scientific activities, material is a part of the physical environment and is the main target of students’ exploration. In order to arouse students’ desire to explore, we should pay attention to the following aspects when providing materials: first, to provide materials that facilitate students’ operation and observation; secondly, s material. Such as: ”Shen and floating“ activities, students guess the light objects will float, heavy will sink. As a result, we provided fruits, coins, radishes, paper clips, large blocks of wood and other materials, the final experimental results and their vision is very different. Through repeated operation, they gradually realized that ”the severity of an object can not be determined
