④ Pay attention to the process and present it perfectly. In the usual experimental practice, we must pay attention to the details and process of the experiment, and standardized experimental operation is a necessary condition for getting full marks.

Before the experiment, we should observe the name, measuring range and dividing value of the equipment used to check whether the equipment is in good condition. During the experiment, we should strictly follow the steps and pay attention to every detail; After the experiment, the experimental equipment, all medicines and instruments should be put in order, and the experimental platform should be cleaned.
