About SSS3 Physics Scheme of Work

Physics is the study of the laws that govern matter, energy, and their interactions. It covers fundamental concepts such as motion, forces, energy, electricity, magnetism, waves, and nuclear physics. Physics helps us understand the workings of the universe, and it is crucial for technological progress. It underpins fields like engineering, medicine, and computer science, enhancing critical thinking and problem-solving abilities.

The Lagos state unified scheme of work for Physics in SSS3 builds on what students have learned in SSS1 and SSS2, helping them get ready for the West African Senior School Certificate Examination (WASSCE). It covers important topics like motion, forces, energy, electricity, magnetism, heat, and modern physics concepts. It also includes practical experiments to help students see how physics works in real life. By learning these topics, students get a good mix of theory and hands-on experience.

The WASSCE is a big exam that SSS3 students need to pass to go to university or start their careers, and the Lagos state unified scheme of work for SSS3 physics is designed to help students do well on this exam. Good physics knowledge helps students think critically and solve problems and equally equips them with skills that are useful for the WASSCE and their career development.

Assessment Guide

SSS3 students in Nigeria are assessed in Physics through continuous assessments and the WASSCE. Continuous assessments include class tests, assignments, oral presentations, projects, and class participation. The WASSCE consists of multiple-choice questions, essays, and practicals. These assessments evaluate a range of skills, ensuring holistic evaluation, skill development, preparation for higher education and careers, and identifying areas for improvement.
