实验题是高考试题的难点,也是重点,灵活多变。实验设计类实验从题型方面看可分为验证性实验、探究性实验和评价性实验,从命题的切入点来看以新的信息材料呈现,重点考查实验设计能力。三、实验设计的基本技能1.验证性实验【典例分析】例1:为了验证叶片光合作用受到光质的影响,请用所提供的实验材料与用具,在给出的实验步骤的基础上,继续完成实验步骤的设计和预测实验结果,并对你的预测结果进行分析。
Experimental questions is the difficulty of college entrance examination questions, but also focus, flexible. Experiment design experiment can be divided into verification experiment, exploratory experiment and evaluation experiment from the aspect of question type. From the starting point of the proposition, the new information material is presented, focusing on the experimental design ability. Third, the basic skills of experimental design 1. Confirmatory experiment [Example Analysis] Example 1: In order to verify the leaf photosynthesis by light quality, please use the experimental materials and appliances provided, based on the experimental steps are given , Continue to design the experiment steps and predict the experimental results, and analyze your forecast results.
