Introduction to Basic Science as a School Subject
Basic Science is a school subject that introduces students to the study of nature, the environment, and how things work. It combines ideas from Physics, Chemistry, Biology, and Earth Science in a simple way that young learners can understand. The subject helps students to develop curiosity, observation skills, and problem-solving abilities. Through Basic Science, students learn about living and non-living things, the human body, matter, energy, and how to care for the environment. It lays the foundation for advanced science subjects in higher classes.
