What is the general topic of physics class in teacher recruitment interview? The scope is the first volume of the second day of junior high school.

The first volume of physics in Grade Two is basically acoustic optics, and there are changes in state, mass and density.

As a teacher recruitment interview, generally speaking, the most likely problem in these aspects is the distinction of voice characteristics, mainly the loudness of tone. In optics, the emphasis is on the reflection of straight-line propagating light, the refraction of plane mirror imaging light and convex lens imaging. The problems that are easy to occur in the change of state of matter are melting and solidification, vaporization and liquefaction of matter. The main problems in mechanics are the measurement of mass and density, and the relationship between mass and volume.

So these questions are the easiest to test. Please summarize this part.

If it is a lecture, be sure to make clear the position of this section in the whole chapter or the whole physics. At the same time, we should explain the main knowledge points in this section in depth, and also talk about other knowledge points as a foreshadowing.

The main thing here is to look at your expressive ability of speaking language, and also pay attention to your dress.
