, aimed at creating creative capacity. A device made up of tomatoes, nails and copper keys is used to receive current meters with a steering line and is then placed on a physical projector. Moreover, the chemistry discipline is characterized by experimentation, and we should also pay special attention to experimental teaching。Experimental phenomena: z, , colour of solution. Experimental phenomena: pointers for current meters , colour of solution . Pointers. Pointers. The buttons are broken, the zinc is dissolved, and there are bubbles here. So, as the learning process draws to a close, there is a very strong need for re-energizing students ' knowledge. (2) two different active metals. Animated in the form of animated images, students will be very interested in the wide range of battery applications available to students, and will be able to make them feel the greatness of a high-tech country, inspire their patriotism and thus broaden their horizons. 3. The polar divide forms a closed circuit. Negative zinc: zn-2e - = zn 2+ (oxidized reaction) positiveOriginal battery1. There are two electrodes of varying activity. At the same time, students can watch animations, see zinc melts into zinc ions, and hydrogen ions get electrons in the form of hydrogen bubbles, and when the buttons close, they can see the directional movement of electrons. The original battery works in this class
