问题 解答题

生物学的科学探究过程大致包括六个环节:______,______,______,______,______,______.

答案

探究的一般过程是从发现问题、提出问题开始的,发现问题后,根据自己已有的知识和生活经验对问题的答案作出假设.设计探究的方案,包括选择材料、设计方法步骤等.按照探究方案进行探究,得到结果,再分析所得的结果与假设是否相符,从而得出结论.并不是所有的问题都一次探究得到正确的结论.有时,由于探究的方法不够完善,也可能得出错误的结论.因此,在得出结论后,还需要对整个探究过程进行反思.即科学探究的一般过程:提出问题、作出假设、制定计划、实施计划、得出结论、表达和交流.

故答案为:提出问题;作出假设;制定计划;实施计划;得出结论;表达交流.
