Science is a systematic study of natural phenomena. It is a discovery-oriented subject that deals with the observation, identification, description, experimentation, and theoretical explanation of natural phenomena. It has two main branches: physical science and life science. Physical science deals with the inanimate world, while life science deals with the animate world and the relationship between them. 

Class 7 is an important class for students as it lays the foundation for future studies. In this class, students learn about the basics of science which include the introduction to science, physical science, and life science. In addition, they also learn about the scientific method, the characteristics of a scientific theory, and the difference between a fact and a hypothesis.
