小学自然学科担负着对学生进行科学启蒙教育的重要任务。达尔文说:“科学就是积累事实、发现规律。《美国国家科学教育标准》指出学习科学是学生自己去做而不是别人为他们做的事情,提出了“听会忘记、看能记住、做才能会”的口号。因此自然教学必须让全体学生参与以探究为目的的研究性活动,让学生积极参与、自行发现问题、提出问题、自行设计探究的程序、自行得出结论规律, Natural science primary school shoulder the important task of scientific enlightenment education for students.

They put forward the idea of ​​“listening to forget, remembering, Will be ”slogan.Therefore, natural teaching must involve all students in the research activities for the purpose of inquiry, so that students can participate actively, find out problems, ask questions, design their own inquiry procedures, draw conclusions on their own,
