设计性实验就是按照题目要求由考生根据实验目的,运用相关的物理规律,迁移教材中的实验方法,选择熟悉的仪器,安排正确的实验步骤自行独立设计的实验方案。1.设计性实验的设计思路解决设计性实验的关键是确定正确的实验原理,正确的实验原理是进行实验设计的根本依据。考生可根据已掌握的物理知识找出相关的物理规律,根据问题的要求和给出的条件,构建相关的物理情景,并根据已掌握的基本仪器测出所要测定的物理量。有时,对于同一个实验要求,可以构建不同的物理情景,导出不同的物理量的表达式,会有不同的
Design experiments are based on the subject required by the candidates according to the purpose of the experiment, the use of the relevant laws of physics, the migration of teaching materials in the experimental methods, select the familiar instruments, arrange the correct experimental steps independently designed experimental program. 1.Design experiment design ideas Solve the design experiment is the key to determine the correct experimental principle, the correct experimental principle is the fundamental basis for experimental design. Candidates can identify the relevant physical laws based on the available physical knowledge, construct relevant physical scenarios according to the requirements of the questions and the conditions given, and determine the physical quantities to be measured based on the acquired basic instruments. Sometimes, for the same experimental requirements, you can build different physical scenarios, derive expressions of different physical quantities, there will be different
