化学是以实验为基础的一门自然科学，通过化学实验不仅可以考查学生基础知识掌握的情况，而且还可以进一步考查学生的实验动手操作能力、逻辑推理能力、发散思维及创新能力，因此实验题已成为近年来中考的热点试题之一。下面我们以2005年安徽中考部分化学实验题为例作一探析。 一、老知识新视角考查学生基础知识运用能力 例1 (2005年安徽中考题)某种牵牛化(如图所示)清晨是粉红色，下午却变为蓝
Chemistry is a natural science based on experiments. Through chemical experiments, students can not only examine the basic knowledge of students, but also can further examine students’ experimental hands-on ability, logical reasoning ability, divergent thinking and innovative ability. Has become one of the hottest questions in recent years. Here we take an example of a chemistry experiment in the 2005 Anhui Provincial Entrance Examination as an example. First, a new perspective of old knowledge examines students’ basic knowledge. Example 1 (2005 Anhui exam questions) Some kind of geranihua (shown in the picture) is pink in the morning and blue in the afternoon.
