1, Introduction: First of all, you can briefly introduce the background and purpose of the swing experiment. For example, we can say, "Today we are going to do an interesting experiment-the swing experiment. Through this experiment, we can better understand the swing and periodic motion in mathematics. "

2. Experimental process: Next, you can describe the process of swinging experiment in detail. For example, you can first introduce the materials and tools needed for the experiment, and then describe each step of the experiment in chronological order. In the process of description, some vivid language can be used to make readers feel the process of experiment better.

3. Experimental results: After describing the experimental process, the experimental results can be summarized. For example, it can be said: "Through this experiment, we found that the movement of the swing is regular, and it presents a periodic movement."

4. Conclusion: Finally, the experiment can be summarized. For example, we can say, "Through this experiment, we not only learned the knowledge about swing and periodic motion, but also exercised our observation ability and hands-on ability."

Matters needing attention in doing experiments

1, safety first. In the laboratory, you should strictly abide by the safety regulations of the laboratory and wear necessary personal protective equipment, such as laboratory clothes, gloves and goggles. At the same time, attention should be paid to safe operation when using chemical reagents to avoid contact with skin and inhalation of harmful gases.

2. Full preparation. Before the experiment, we should fully understand and prepare the purpose, principle and method of the experiment. Read the relevant literature, understand the experimental steps and required materials, and prepare the required reagents and equipment.

3, the experimental operation specification. During the experiment, we should operate according to the experimental steps and requirements, and pay attention to controlling the experimental conditions, such as temperature, time and concentration. At the same time, we should carefully observe the experimental phenomena, record the experimental data and deal with the abnormal situation in time.

4. Accurate data processing. After the experiment, the experimental data should be processed and analyzed. According to the experimental requirements, appropriate statistical methods are selected for data processing, and the results are displayed and explained in the form of charts. At the same time, we should pay attention to the reliability and repeatability of data.
