解探究题要注意:①依据已知信息,联系已有经验和知识,有理有据地提出猜想和假设。②验证假设的途径和方法有多种,需从物质的物理性质、化学性质等方面入手,进行多角度、多途径分析,才能设计出多样化的实验方案。③优化实验方案时,应选择原理正确、药品常见、操作简便、现象明显、安全、无污染的实验方案。要熟悉科学研究方法,即观察法、实验法、类比法、社会调查法、数据统计法
Solving the inquiry questions should pay attention to: 1 based on known information, contact existing experience and knowledge, and make reasonable guesses and assumptions. 2 There are many ways and methods to verify the hypothesis. It is necessary to start from the aspects of physical properties, chemical properties, etc., and carry out multi-angle and multi-path analysis to design a diversified experimental scheme. 3 When optimizing the experimental program, choose an experimental scheme with correct principles, common drugs, simple operation, obvious phenomena, safety, and no pollution. To be familiar with scientific research methods, namely observation, experiment, analogy, social survey, and statistics
