Introducing science to first graders is crucial as it lays the foundation for a lifelong interest in understanding the world. Earth and Space Science helps young students appreciate the planet they live on and the vast universe beyond, sparking curiosity about natural phenomena. Life Science fosters an early understanding of living organisms, their environments, and the interdependence of life, encouraging respect for all forms of life. The study of Waves, through simple concepts like sound and light, introduces children to fundamental physical principles and nurtures their inquisitiveness about how things work. These units together build a holistic scientific awareness that is essential for their cognitive and social development.
