The document outlines a daily lesson plan for a Form 4 physics class on the topic of electric and electromagnetism. The lesson focuses on explaining electromotive force (emf) and internal resistance, as well as conducting an experiment to determine the emf and internal resistance of a dry cell. Students will learn about sources of emf like batteries and generators, carry out related activities, explain emf with teacher guidance, and conduct an experiment to determine emf and internal resistance of a dry cell. Their understanding will be assessed through answering questions and an exit ticket at the end of class.
