Physical Science in Grade 7 introduces students to the principles of matter, energy, motion, and forces. Through inquiry learning, learners ask questions about how the physical world works, test ideas with experiments, and reflect on evidence. Instead of only memorizing formulas, they explore patterns, design models, and connect science to real-life applications. Activities such as lab investigations, simple machines, and energy experiments make learning practical. By linking theory to experience, Physical Science becomes a way to understand nature, solve problems, and innovate for the future.
