Physical Science in Grade 9 introduces students to the fundamental principles of physics and chemistry that explain how the universe works. This subject emphasizes observation, experimentation, and problem-solving to build a foundation for advanced science courses. Learners explore concepts such as motion, forces, energy, matter, and chemical reactions, connecting them to real-world applications like transportation, technology, and energy use. By examining the structure of atoms, the behavior of waves, and the laws of motion, students learn how scientific ideas describe both everyday experiences and natural phenomena. Physical Science also highlights the role of evidence, measurement, and models in building scientific knowledge. By the end of the course, students see science not only as abstract theory but as a practical tool for innovation, critical thinking, and understanding the world around them.
