Students, the two-year moral and life course is about to end. We have studied and solved many problems in the past two years. Do you remember how we did it? Let's summarize.<br>Visit, visit, ask questions to understand the situation, collect written information, statistics, etc. are all commonly used methods for investigating problems.<br>Many changes happen little by little, so we need to observe carefully and patiently to see the results.<br>Do small experiments by yourself, you will find a lot.<br>Make a comparison before and after observing and recording things, and you will find more surprises.<br>We will come up with many good ideas when we discuss the problem together.<br>Recall the activities you participated in, write, say and see what research methods are used.<br>Students, I hope you will continue to study hard after the third grade. You will find these methods very useful for your future study. I wish you continuous progress!<br>
