Parents and teachers should care about Normal Physical Science for children aged 7-9 because during these formative years, kids are naturally curious and eager to explore the world around them. Introducing them to physical science helps nurture an early interest in how things work, laying a strong foundation for future learning in STEM (Science, Technology, Engineering, Mathematics) fields.

Children's brains are highly receptive at this age, making it an optimal time for them to absorb fundamental scientific concepts. Engaging in hands-on experiments and observations can foster critical thinking, problem-solving skills, and creativity. These activities not only make learning enjoyable but also help children understand and apply their knowledge to real-world situations, enhancing their comprehension and retention.

Moreover, early exposure to physical science encourages positive attitudes toward learning. By demonstrating that science is not just a school subject but a way of understanding the universe, parents and teachers can instill a lifelong love for discovery and learning. This enthusiasm can boost children's confidence, motivation, and academic performance across subjects.

In addition, understanding basic science promotes environmental awareness and responsible decision-making, crucial in today's world. Overall, supporting early science education sets the stage for well-rounded cognitive development and prepares children for a future in an increasingly science-centric world.
