The fifth chapter deals with eight grade. In addition to cross-curricular connections with Chemistry, Mathematics, and Art culture connections were also found to the subjects of Biology, Physics, and Geography. During the description, below each example are listed learning outcomes achieved, tools necessary for task creation and method of implementation. Most of these examples require a certain period of work, so they can be realized as project tasks.
