Learning material is a covalent bond. Learning resources in the form of textbooks. I also present material in the form of power points. In the power point I present there are important points from the material and a more detailed explanation of the material. At the end of the lesson I gave a tournament that was held in groups. The tournament is to give a name to each compound formula given. The group that can solve the problem quickly and correctly will be given a prize that I have prepared in the form of goods from Indonesia. All the media I use have been provided by the school, such as projectors, whiteboards and markers.
