Physics is the branch of science that deals with the study of matter, energy, and their interactions. In Class 7, students are introduced to various concepts such as motion, force, light, heat, sound, and electricity. They learn about different types of motions, effects of force, behavior of light, heat transfer, properties of sound, and basic electrical circuits.


Chemistry is the branch of science that deals with the composition, properties, and changes of matter. In Class 7, students learn about the basic concepts of chemistry such as elements, compounds, mixtures, acids, bases, and chemical reactions. They also explore the periodic table and learn about the properties and uses of common substances.


Biology is the branch of science that deals with the study of living organisms. In Class 7, students learn about the basic concepts of biology such as cells, tissues, organs, and organ systems. They also study plants and animals, their life processes, adaptations, and the environment they live in. Additionally, they learn about reproduction, nutrition, respiration, and other important biological processes.


Earth science is the branch of science that deals with the study of the Earth and its components. In Class 7, students explore topics related to the Earth's structure, layers, and composition. They learn about the rock cycle, types of rocks, minerals, weathering, erosion, and deposition. Students also study natural disasters such as earthquakes and volcanoes, as well as the Earth's atmosphere, weather, and climate.


Environmental science is the branch of science that deals with the study of the environment and its interactions with living organisms. In Class 7, students learn about the importance of environmental conservation, natural resources, pollution, and sustainable development. They also study ecosystems, food chains, and the impact of human activities on the environment.


Astronomy is the branch of science that deals with the study of celestial objects and phenomena. In Class 7, students learn about the solar system, the Sun, the Moon, and the planets. They also explore concepts such as eclipses, seasons, and the motion of celestial bodies. Additionally, they study the history of astronomy and the tools used by astronomers.

In Class 7, students gain a foundational understanding of these branches of science, laying the groundwork for further exploration and specialization in higher grades. This multidisciplinary approach helps them develop a holistic understanding of the natural world and its phenomena.
