There are several branches of science that are introduced to students in Class 3. These branches help children to develop a basic understanding of scientific concepts and encourage them to explore the world around them. Here are some of the main branches of science introduced in Class 3:


Life science, also known as biology, is the study of living organisms. In Class 3, students learn about various aspects of life science, such as plants, animals, and the human body. They learn about the different parts of plants and their functions, the life cycle of animals, and the basic structure and functions of the human body.


Physical science is the branch of science that deals with the study of non-living things. In Class 3, students are introduced to basic concepts of physical science, including matter, energy, and forces. They learn about different forms of matter, such as solids, liquids, and gases, and how they can change from one form to another. They also learn about different types of energy, such as light, heat, and sound, and how forces can affect the motion of objects.


Earth science is the branch of science that focuses on the study of the Earth and its natural processes. In Class 3, students learn about various aspects of earth science, including the Earth's structure, weather, and natural resources. They learn about the different layers of the Earth and their characteristics, the water cycle, different types of weather patterns, and the importance of conserving natural resources.


Environmental science is the branch of science that deals with the study of the environment and its components. In Class 3, students learn about the importance of taking care of the environment and how their actions can impact it. They learn about concepts such as pollution, recycling, and conservation. They also learn about different ecosystems and the importance of biodiversity.


Astronomy is the branch of science that deals with the study of celestial objects, such as stars, planets, and galaxies. In Class 3, students are introduced to basic concepts of astronomy, such as the solar system, the moon, and the different phases of the moon. They also learn about the importance of observing the sky and the tools used by astronomers.

Overall, the introduction of these branches of science in Class 3 helps students develop a curiosity for the world around them and lays the foundation for further scientific learning in higher grades.
