对种子所处环境的温度、水分、空气等条件分别进行控制,从而了解种子萌发的条件.这是运用了科学探究方法中的______法(填“观察”或“实验”).

答案

(1)观察是科学探究的一种基本方法.科学观察可以直接用肉眼,也可以借助放大镜、显微镜等仪器,或利用照相机、录像机、摄像机等工具,有时还需要测量.步骤:①要有明确的目的;②要全面、细致和实事求是,及时记录;③要有计划、要耐心;④要积极思考;⑤要交流看法、进行讨论.

(2)探究实验是探索生命的重要方法,探究的过程是从发现问题、提出问题开始的,发现问题后,应用已有的知识和生活经验对问题作出假设,制定并实施探究计划,根据实验现象,分析结果,得出结论,最后表达交流探究过程和结论.

观察法与实验法的本质区别是否对研究对象施加有影响的因素;联系是实验法是以观察法为基础.由于对种子所处环境的温度、水分、空气等条件分别进行控制,从而了解种子萌发的条件.这是运用了科学探究方法中的实验法.

故答案为:实验法.
